Study: It’s Easier For Cities To Reduce Residential Emissions Than Transportation Emissions

It’s easier for cities to reduce their greenhouse gas emissions through the residential sector than it is through the transportation sector, a new study authored by an MIT professor has found. The primary ability to do so is through better construction practices, not increased housing density, interestingly.

The study findings are the result of an analysis seeking to determine the best ways for local planning policies to either complement the Obama administration’s Clean Power Plan or to make up for its absence. (As it stands, it’s looking less and less likely that the Clean Power Plan will ever go into effect).

“Our take-home message is that cities can do a lot at the local level with housing stock,” stated study co-author David Hsu, an assistant professor in MIT’s Department of Urban Studies and Planning, while also noting that: “In transportation, cities can’t make up for the loss of a national strategy.”

The researchers do note, though, that there’s wide variation with regard to possibilities based on the city — with the potential being much greater in fast-growing cities such as Houston as opposed to older cities like Boston.

The press release provides more: “To conduct the study, the researchers examined economic, environmental, and demographic data from 11 major US cities, then developed models projecting emissions through the year 2030, based on a series of different policy scenarios.

“For instance, to analyze ways of cutting emissions from residential energy by 2030, the researchers modeled a baseline scenario in which housing characteristics remained the same. They also modeled scenarios featuring a variety of changes, including the implementation of new energy-efficient construction standards, the building of more multifamily homes, and the retrofitting of homes to save energy.

“Simply requiring newly built homes to be more energy efficient would reduce residential emissions by an average of 6% by 2030. But requiring existing homes to be retrofitted would yield a further 19% reduction of residential emission, on average, across the 11 cities.”

Interestingly, reducing the number of single-family homes by 25% and replacing them with multifamily units “would have virtually no incremental benefit in terms of reduced residential energy use and CO2 emissions” — apparently owing to the fact that when single-family homes are made more energy efficient, the possible gains from multifamily designs are greatly lessened.

As a final note here, the residential sector currently accounts for around 20% of all US carbon dioxide emissions.

The new study is detailed in a paper published in the Journal of Planning Education and Research.

EDF Energy Renewables announced plans to sell its majority stake in five wind farms across Cambridgeshire and Lincolnshire for £98m in order to release equity to invest in developing further renewable projects elsewhere in the UK.

However, while selling its majority stake to clean energy investor Greencoat UK Wind PLC, the UK renewables arm of the French utility giant said it would keep a 20 per cent stake in the projects and continue to operate and provide maintenance for the wind farms.

EDF Energy will also continue to purchase all of the electricity generated at the sites, while operational and community benefit fund arrangements will remain unchanged, the firm said.

The five wind farms covered by the transaction are Deeping St Nicholas, Lincolnshire – 16.4MW, Red House, Lincolnshire – 12.3MW, Glass Moor, Cambridgeshire – 16.4MW, Red Tile, Cambridgeshire – 24.6MW, Bicker Fen, Lincolnshire – 26.6MW.

Matthieu Hue, CEO of EDF Energy Renewables, said the move formed part of EDF Group’s wider CAP 2030 renewable energy development strategy, with the UK seen as a major strategic market for the company.

“We have built close ties with the communities around these sites and we know they value industry partners they can work with over the long term,” said Hue in a statement. “That’s why it is important to us to continue to run the wind farms and maintain local relationships.

“We have an ambitious development portfolio, which will help us deliver the low carbon electricity the country needs,” he added. “This sale helps to support our ambitions and our delivery of new projects around the UK.”

Across the UK, the company already operates more than 696MW of wind farms, has more than 260MW under construction and has more than 454MW consented, 170MW in planning and 950MW in development.

Tim Ingram, chairman of Greencoat UK Wind, said the firm would take an 80 per cent stake in the wind farms, which comprise 47 turbines: “Following on from our recent further share issue, we are pleased to acquire assets from a tenth seller, a third major utility partnership, demonstrating UKW’s reach across the market in finding value for investorsm,” he said in a statement.

The news comes as Shell today announced it had completed the sale of several UK North Sea assets as well as its entire Gabon onshore oil and gas interests.

The oil major has sold a package of UK North Sea assets to Chrysaor for a total of up to $3.8bn, although it said it retains “a significant, more focused and strengthened presence in the UK North Sea, to which it remains committed”.

Meanwhile, Shell has sold its entire oil and gas interests off the coast of Gabon in West Africa – which in 2016 produced the equivalent of 41,000 barrels of oil per day – to Assala Energy Holdings Ltd for a total of $628m.

The company said the completion of the Gabon deal showed “the clear momentum behind Shell’s $30bn divestment programme and is in line with Shell’s drive to simplify the upstream portfolio and re-shape the company into a world class investment”.

Last Saturday, Every Fourth Light Bulb in Europe was Powered by the Wind

As you settled down to watch Strictly Come Dancing last Saturday evening there was a one in four chance your TV was being powered by the wind.

Trade body WindEurope confirmed yesterday that the European wind power sector set a new record last weekend, meeting 24.6 per cent of EU electricity demand on Saturday 28th October.

The group said the performance smashed the previous record of a 19.9 per cent share, which was set earlier in the month on 7th October.

The on-going expansion in Europe’s wind power capacity combined with strong northern winds and a continent-wide cool polar air mass to deliver the record performance.

Hourly output records also fell across the region, with the EU as a whole setting a new record of 89.9GW on Saturday evening. Germany also set a new record of 39.1GW, Poland delivered a record 5.1GW and Norway achieved a new high of 900MW.

In addition, Denmark saw 109 per cent of its power demand met by wind power.

Onshore wind dominated the market, delivering 21.8 per cent of European power throughout the day, while offshore wind provided a further 2.8 per cent.

The results come as two of Europe’s biggest economies continue to work on strategies that could deliver a further boost to the continent’s renewables sector.

Germany’s coalition talks could yet deliver a revamp of the country’s faltering climate strategy, which has been accused of failing to deliver on the government’s ambitious climate targets.

The leader of the Greens this week warned that it would not continue talks with Angela Merkel’s Christian Democratic Union and the centre right Free Democrats (FDP) unless the FDP officially endorses the country’s carbon targets.

The FDP had signalled it wants the goal of cutting emissions 40 per cent by 2020 – which Germany is on track to miss – to be reassessed. But Simone Peter, co-chair of the Greens, told Reuters the targets were non-negotiable.

“Before exploratory talks continue, the FDP must accept unconditionally the climate protection goals,” Peter said. “Otherwise the talks make no sense.”

Green groups are optimistic Merkel could seek to reinvigorate Germany’s decarbonisation strategy in order to secure the support of the Greens. However, she faces a tricky political challenge squaring the carbon targets with the FDP’s concerns.

Meanwhile, France’s Environment Minister Nicolas Hulot told Le Monde this week that the government would come forward with a new ‘Green Deal’ plan next year, designed to make good on its promise to reduce reliance on nuclear power and step up renewables deployment.

US Signs Deal With Denmark To Expand Offshore Wind Energy Cooperation

Foto-ilustracija: Pixabay

A new deal calling for further cooperation in the offshore wind energy sector has been signed by the US and Denmark, thanks to a fairly positive view of wind energy within the Trump Administration, according to recent reports.

The new agreement means that top Europe-based wind energy firms, such as DONG Energy and Vestas, should have an easier time developing projects and relationships within the US market.

“We see some positive initiatives coming out of the administration in Washington,” commented the head of DONG’s US business, Thomas Brostroem, in an interview with Reuters, while referencing efforts to streamline on the federal level the permitting process for offshore wind energy projects. “They’ve been really receptive to talk to European countries and developers to get know-how from the past decades.”

Reuters provides more: “Danish companies DONG Energy and Vestas had feared the nascent US offshore wind sector would be stymied after President Trump vowed to revive the coal industry, challenged climate-change science and blasted renewable energy as expensive and dependent on government subsidies. But both companies now say the Trump administration is increasingly looking at Europe’s experience as it seeks to kick-start the sector.

“The US offshore wind sector, which has lagged behind Europe, is at a critical juncture, with the first large-scale offshore wind auction in Massachusetts coming up in December. But to gain traction, industry executives and experts say the United States will need to replicate the dramatic cost cuts which Europe has implemented.”

This news follows on the continuing growth of the European offshore wind energy sector in recent years — with more than 12 gigawatts (GW) of offshore wind energy generation capacity now installed in the region.

“It is a huge scoop that we now get a formal cooperation with the Trump administration on offshore wind,” stated Danish climate and energy minister Lars Chr Lilleholt. “There’s no doubt that this is a sleeping giant.”

No, this indeed does not match well with what we’ve otherwise seen from the Trump administration on energy, but perhaps there is some hope in policies around this renewable energy arena.

Extreme Summer Heat Becoming More & More Prevalent Across US, Study Finds

Photo-illustration: Pixabay
Photo-illustration: Pixabay

The number of days in which extreme heat occurs during the summer have been rising across the US — particularly in the Western states and on the Eastern seaboard — over recent decades, a new study from the Natural Resources Defense Council found.

To be more particular, the study found that nearly two-thirds of the US has dealt with far more days of extreme summer heat over the last decade than during previous decades, with the study relying on temperature data from thousands of US government weather stations throughout the US. The new analysis compared data taken between 2007–2017 and 1961–1990.

The work identified 21 states (along with the District of Columbia) that were particularly hard hit — these states were ones where at least 75% of the residents are now dealing with “at least nine more than expected extreme summer heat days annually.”

NRDC provides more: “Severe heat is the number one cause of U.S. weather fatalities. High summer temperatures can cause heat exhaustion and heatstroke or worsen preexisting cardiovascular and respiratory conditions. Research has shown that more than 65,000 people end up in U.S. emergency rooms each summer with heat-related illnesses and an estimated 1,300 additional deaths occurred annually during extreme summer heat across 40 major US cities from 1975 to 2004. …

“City residents face a heightened risk because of the urban heat island effect, caused by the mostly paved urban surfaces that absorb and re-radiate heat. A lack of green space and tree cover in urban areas can substantially raise temperatures compared to surrounding regions. An NRDC study from earlier this year found that large cities like New York, Philadelphia, Chicago, and Boston could each experience at least six times as many dangerously hot summer days by 2100 as they did, on average, from 1975 to 2010. The study also found that, collectively, 45 major urban areas in the United States could see about 28,000 more deaths each year due to extremely hot summer days by the 2090s.”

As you’ve probably already noted, the recent forest fires seen along the West Coast of the US were fueled by high temperatures and the aridity accompanying them. As it stands, Southern California is right now in something of a heatwave — a somewhat strange occurrence for an October.

California is, notably, one of the 11 Western states identified by the new study as being most affected by rising levels of extreme summer heat.

Air Quality In Northern China During September Was Just As Bad As Last Year, Despite Reduction Initiatives

Foto-ilustracija: Pixabay
Photo-illustration: Pixabay

Despite all of the work put in as part of a campaign to reduce air pollution there, air quality in Northern China was just as bad in September 2017 as it was in September 2016, data from the Ministry of Environmental Protection (MEP) has revealed.

Considering the actions taken by the government there this year, the news doesn’t bode well for the country’s ability to greatly reduce its growing air pollution problems — and may end up provoking a negative public reaction considering the government’s promise to clean things up somewhat by the end of the year.

To be more specific here, PM2.5 levels in the Beijing-Tianjin-Hebei area during September 2017 were around 52 micrograms per cubic meter, the same as during September 2016.

It should also be noted that the country’s PM2.5 levels actually rose to 64 micrograms per cubic meter over first 9 months of 2017 — up 10.3% year-on-year, despite atarget of reducing the yearly average by 15% during 2017.

“Of 74 cities monitored by the MEP, Beijing, Tianjin, Zhengzhou in Henan, Taiyuan in Shanxi and six cities in Hebei province, including the steel producing city of Tangshan, were China’s most polluted cities last month,” Reuters notes.

“All of the cities were among the 28 named by the MEP in August to be subject to a major campaign to tackle air pollution this winter. But ahead of the campaign, local authorities had already begun to inspect factories, forcing many to shut down some of their operations during September. Hebei province has sent out 1,400 inspectors to conduct environmental checks across the province since early September.”

All of this comes just before the winter heating surge begins in the country — which sees coal-fired heating plants rapidly ramp up output, with air pollution levels rising in response.

Plans this year, though, are to require the energy-intensive steel, cement, smelting, and coke industries to stagger production, and to limit use of coal-fueled trucks, from the middle of November until the middle of March. It remains to be seen how effective these plans will be.

Record Loss Of Global Tree Cover In 2016, Driven By Forest Fires

Foto-ilustracija: Pixabay
Photo-illustration: Pixabay

The record loss of global tree cover in 2016 — totaling around 297,000 square kilometers (114,672 square miles) and representing a rise of 51% on 2015 — was driven partly by increasingly common wildfires driven by rising temperatures and drought, according to the Global Forest Watch (GFW) which utilized data provided by the University of Maryland.

“We saw quite a dramatic spike in 2016,” stated Mikaela Weisse, a research analyst at the US think-tank World Resources Institute, which oversees GFW. “That seems to be related to forest fires in countries including Brazil, Indonesia and Portugal.”

Altogether, tree cover equivalent to the full size of New Zealand was lost in 2016. (It should be noted here that GFW measures the actual loss of global tree cover, and doesn’t attempt to estimate net changes in forests to account for possible re-growth and tree planting.)

“By contrast, the UN’s Food and Agriculture Organization, using different methods, says the net global rate of deforestation has slowed by more than 50% in the last 25 years,” Reuters reports.

“GFW said Brazil’s Amazon region lost 37,000 square kilometers of tree cover in calendar 2016, almost three times more than in 2015. That contrasts with official Brazilian data showing that deforestation in the Amazon fell 16% in August 2016 to July 2017 compared with the same period a year earlier. Brazil said it was the first decline in three years. Brazil’s environmental agency Ibama said 2016 was the ninth-worst year for forest fires since monitoring began in 1998.”

So, what do you know, based on GFW figures, it appears that official deforestation data from the Brazil and the UN (amongst many others) underestimate the problem — what a surprise.

Reuters continues: “Weisse said GFW data often detected smaller-scale losses in tree cover, including in layers beneath the forest canopy, while the Brazilian data was better at recording clearances of large blocks of forest. GFW said Indonesia lost almost 1 million hectares of tree cover in 2016, probably the delayed result of a severe fire season in 2015.”

It seems very likely that we can expect to global tree cover continue disappearing rapidly as temperatures continue climbing and drought continues becoming more common — as that occurs, intense wild fires will become more and more common.

Recall this year’s forest fires on the West Coast of North America and in the Mediterranean if you want to understand where things are headed — it’s only going to get worse from here on out.

Air Mapping Initiative Reveals London’s Most Polluted Postcodes

The most polluted postcodes in London have been identified as part of a year-long initiative which saw thousands of personal air quality smart sensors handed out to local groups, businesses, and communities to help draw up a picture of pollution levels across the UK capital.

Using Drayson Technologies’ CleanSpace tags, the initiative generated more than 15 million local carbon monoxide (CO) data readings over a 12-month period. It revealed that WC1N – an area encompassing Great Ormond Street Hospital and the Brunswick Centre in Bloomsbury – had the highest overall readings for the pollutant.

It was followed in the pollution league table by W10 – spanning parts of Wormwood Scrubs prison, Ladbroke Grove and West Kilburn – and WC2, which covers parts of the West End as well as Charing Cross and Embankment tube stations.

Bishops Bridge Road near Paddington Station, followed by Euston Road and Great Portland Street were also identified as specific roads in London with the highest CO levels, according to the clean tech firm.

The initiative was also able to identify specific times of the year and day when pollution levels were at their worst, with the highest peak average of CO measured on 23 January this year – when the Mayor of London issued the city’s first ‘Black Alert’ for air pollution.

Repeatedly high levels were also measured throughout November 2016 to February 2017, which Drayson Technologies said indicated that the air is dirtier in London during the winter months.

Meanwhile, the most polluted times of the day were on average seen between 8.51am and 9.21am each morning, as well as during the evenings between 8pm and midnight, spikes which the firm said were most likely due to Londoners being exposed to pollutants inside bars, restaurants or other buildings.

First launched last year by Drayson Technologies in partnership with charity the British Lung Foundation, the Map London initiative also saw green private car hire service Greentomatocars fit its vehicles with CleanSpace tags, generating 1.5 million readings from their daily journeys.

The company said it measured CO – rather than other pollutants such as nitrogen oxides or particulate matter – because it is found in both indoor and outdoor environments, with testing having shown that carbon monoxide “correlates well with all other major urban pollutants across seasons”.

Lord Drayson, chairman and CEO of Drayson Technologies, said the aim of the initiative was to help improve Londoners’ awareness of the air they breathe both indoors and outdoors. “We hope the data that we have collected will help people avoid pollution hotspots and allow us to better understand how air pollution impacts people’s health and in turn help Londoners lead healthier lives,” he said.

The results of the year-long campaign follow the launch of London’s Toxicity Charge last week, which means drivers of older, more polluting vehicles now have to pay an additional £10 fee in order to travel in Central London.

ALEKSANDRA ĐURĐEVIĆ Although There Are Neither Chargers nor Incentives in Serbia, Drivers Are Thrilled with BMW Electric and Hybrid Cars

At this year’s Car Show in Belgrade, Delta Motors not only presented visitors a wide range of BMW’s electric, hybrid and plug-in hybrid cars but also decided to place these vehicles on the domestic market.

Many have assessed this as a brave but premature move, as Serbia is still not ready, according to many, for ecomobility.

That is why we chose to talk to Aleksandra Đurđević, General Manager of Delta Motors and find out why “BMW Serbia” team decided to embark on an adventure of placing an electric car on the market.

EP: Why did you decide to sell both electric and hybrid BMW cars in our country? What is your strategy?

Aleksandra Đurđević: Delta Motors Company has introduced this special segment of vehicles, which is – in the context of our country – premature, but as representatives of the BMW Group for Serbia and Montenegro, we exactly want to introduce what is already reality in the world, to our country. We are aware that this is the fastest growing segment and that it has the most obvious prospect in the near future, as fossil fuel vehicles will drastically be reduced or completely out of usedue to the pollution standards that are prescribed in Europe and around the world.

Germany decided not to have vehicles with an internal combustion engine after 2030, so as not to cause further pollution. Electric vehicles ar  present in almost all countries in the region, so we are trying, with the help of foreign partners, to make suggestions and concrete solutions so that this development segment of our market accelerates. The global performance of the BMW manufacturer makes a strong focus on a leading position and we as representatives have no different attitude. We are pleased that our electric cars provoke extremely positive reactions during each test drive.

EP: What are the problems that you, as an importer of electric and hybrid vehicles, face in Serbia?

Aleksandra Đurđević: The challenges of introducing electric vehicles are not small, as it is the case with most new things in the beginning. We have successfully overcome administrative difficulties and now we are waiting for new tasks – initiatives related to  state incentives and infrastructuredevelopment.

The two key questions of a client interested in an electric vehicle are whether there are incentives and what the range of the vehicleis. There is plenty of room for the improvement in our country, primarily in terms of benefits for owners of these vehicles and charger network, which are key initiators for the sale of these vehicles and the impact on drivers’ awareness.

Of course, the use of an electric car is not entirely dependent on the infrastructure, but it implies that the user has a socket at the place where the vehicle is being charged. With a good infrastructure of public chargers, the importance of this factor will be significantly reduced.

BMW Serbia has initiated the development of a national and local strategy for electric vehicles with the Association of Vehicle Importers and Distributors and we believe that our country will opt for the best practices from the region and Europe and apply them in our country. So far as a company we are entering more challenging segments like this one, because we are here to offer our clients only the best from the aspect of innovation, technology, and mobility.

EP: Are people interested and are there any serious buyers? Do some of the interested parties give up because of the obstacles that stand in their way?

Aleksandra Đurđević: Clients are extremely interested, regardless of the fact that currently there is neither network of public chargers nor incentives. Today information is available from all over the world and people are well informed. An increasing number of electric vehicles are on the road, which will certainly affect the accelerated development of the infrastructure.

Electric car is currently being bought as a “second” car in the family, the one that you will primarily use for city driving. There are no obstacles for this kind of use because home charger is enough for our customers. BMW i3 has 200 km autonomy and it is important to note that the cost of maintaining such a vehicle is minimal, as the economic factor is a very important item.

EP: What incentives are offered to importers of “green” BMW vehicles in more developed countries?

Aleksandra Đurđević: Germany has launched an initiative in front of the European Commission to support the installation and expansion of the infrastructure network of chargers throughout its country, which was adopted by the Commission and prescribed a Directive by which all member states are obliged to develop an adequate charging network by 2020. From this, we clearly see that there is a developed awareness of the importance of introducing electric vehicles in Europe, while the very facts about the number of chargers and electric vehicles in the world speak for themselves.

In Japan, there are more chargers than gas stations, 40,000 to 35,000, in China it is planned to have a network of 5 million chargers by 2020, while in the USA there are programs of big incentives for the purchase of electric and hybrid vehicles.

In our country, this segment of ecology is still not being paid enough attention to, while in developed countries a big emphasis is placed on reducing the emissions of harmful gases while driving. Soon it will not be enough for vehicles to have zero emissions only, but they need to be ecological throughout the process, from production to recycling. In fact, only by using electricity generated in an environmentally sound manner in the car production, can the use of electric vehicles completely make sense.

So far as a company, we are entering more challenging segments such as development of national and local strategy for electric vehicles, because we are here to offer our clients only the best from the aspects of innovation, technology, and mobility

Even when the region is concerned, we do not lag behind Europe significantly. In Croatia, there is already a developed network of over 100 chargers, and in 2015 they began with state incentives for the purchase of electric and hybrid vehicles. Fast chargers for all types of new electric cars in Slovenia are located every 50 kilometers, the state provides incentives of 100 percent for the construction of chargers, while the purchase of a new electric car is subsidized with as much as 7,500 euros.

We believe that it is just a matter of time when some of these initiatives will be adopted in our country as well because this is a sure road to ambitious global ecological goals.

EP: Given that the infrastructure of charging stations here is only in the planning phase, what do you offer to potential customers, but also to tourists or business people who have set on a journey in a eco-friendly BMW through our country? Where and how can they recharge their electric vehicles?

Aleksandra Đurđević: Chargers will be available to customers in our facilities. Charging vehicles on our network chargers will be free of charge and the owner of a vehicle, in a more favorable mode of power (at night, when vehicles are most often charged), can pay a completely symbolic price. It is also planned that chargers are installed in Crowne Plaza and Holiday Inn hotels, that our dealer network is fully covered and also that the chargers are installed in Delta City and other shopping centers.

EP: You have introduced your own electric car i3, plug-in hybrid i8, as well as 330e iPerformance at the fair. Can you tell us more about each one of them? Which model stands out most?

Aleksandra Đurđević: BMW in its portfolio has a completely separate segment of electric and hybrid vehicles – “BMWi vehicles”, that are different in all segments from any other BMW vehicle. The goal was to move the engineering borders by creating a car that is the leader in “sustainability” from the point of view of environmental protection, whose trump card is not only the zero emissions of harmful gases.

With model BMW i3 the slogan “Born Electric” emphasizes the most efficient ecological car throughout the whole process, starting from production, usage to vehicles recycling. The BMW i3 is the most outstanding model because it represents the future of urban mobility. The vehicle is about 4 meters long and has a spacious interior. Due to its specific design (car body made from CFRP – Carbon Fiber Reinforced Plastic and batteries placed in the floor of the vehicle), it is extremely dynamic and agile. The total weight of the base model is 1,285 kg. It has an electric power of 125 kW and accelerates to 100 km/h in 7.3 seconds. The autonomy of single-charge is about 200 km depending on the mode of use.

The BMW i8 is a model that promotes the new brand in the best way. It provokes excitement with a great sports design. It is a plug-in hybrid and is powered by two engines: 1.5-litre gasoline engine driving rear wheels rated 170 kW and an electric motor powering the front wheels rated 96 kW. The total system power is 266 kW. When both engines work at the same time i8 accelerates to 100 km/h in 4.4 seconds. The autonomy of the movement in the electric mode is about 30 km and the total is about 440 km. The shell is like the model i3 made from CFRP and the total weight of the vehicle is about 1500 kg.

The 330e is a representative of a special BMW 330e sub-brand to which hybrid cars belong, which are electrified versions of conventional vehicles. The current gamma consists of 225xe, 330e, 530e, 740e and X5 xDrive 40 e. Series 3 is one of the key BMW models and has got its PHEV version. This model is series hybrid and its drive consists of a 135 kW diesel two-litre petrol engine that transfers power to the wheels via an eight-speed gearbox with an integrated 65 kW electric motor. The total system power is 185 kW. Acceleration up to 100 km/h reaches in 6.1 seconds and the autonomy in the electric mode is up to 40 km.

An interesting feature of the current hybrid models is that there is a choice of driving mode, so by using the eDrive button, it is possible to activate “Auto mode” which means  the use of both engines according to the driving conditions. “Save mode” activates the drive on the ICE and uses every opportunity to recharge the battery with regenerative braking. The third type is “E mode”, that is, driving exclusively on the electric drive.

Soon it will not be enough for vehicles to have only zero emissions, but they need to be ecological throughout the process

EP: Many manufacturers of electric vehicles have a problem with battery production technology, tell us about the capacities of your batteries. What does BMW’s plan to introduce in this field?

Aleksandra Đurđević: Since the beginning of the electrification technology, the battery has changed considerably. In the current era of electrification, the first hybrid model was the BMW X6 active hybrid and it used NI MH batteries with which it could only cross 2-3 kilometers in the electric vehicle mode. The current batteries are Li ION. They are made from segments and their reparation is possible by replacing components. Certainly, innovations are primarily reflected in the increase of their capacity, which will affect the increase in autonomy.

Photo: BMW

EP: What does BMW prepare new when it comes to e‑mobility? What models and what features can we expect in the years to come?

Aleksandra Đurđević: By 2020, BMW plans to have more than 30 models in its range with some sort of electric drive. Completely electric vehicles should have the autonomy of about 500 km. By then, some of the BMW conventional models will appear in completely electric versions like the electric X3.

Achieving great autonomy is not a problem at this moment, it is only necessary to install larger batteries, but they would drastically increase the overall weight of the vehicle so that the characteristic BMW driving dynamics would be lost. I believe that the advancement in the construction of batteries will be such that it will be possible to retain our essential “DNA” characteristics and at same time increase the autonomy.

EP: And in the end do you have a message for drivers polluters?

Aleksandra Đurđević: Schedule a test drive with an electric car, I guarantee a unique feeling of driving.

Climate Change Already Damaging Health of Millions Globally, Report Finds

The health of hundreds of millions of people around the world is already being damaged by climate change, a major report has revealed.

Heatwaves are affecting many more vulnerable people and global warming is boosting the transmission of deadly diseases such as dengue fever, the world’s most rapidly spreading disease. Air pollution from fossil fuel burning is also causing millions of early deaths each year, while damage to crops from extreme weather threatens hunger for millions of children.

The findings, published in the Lancet journal, come from researchers at 26 institutions around the world, including many universities, the World Health Organization, World Bank and the UN’s World Meteorological Organization (WMO). The WMO reported on Monday that the level of carbon dioxide in the atmosphere made a record jump in 2016 to hit a concentration not seen for more than three million years.

“Climate change is happening and it’s a health issue today for millions worldwide,” said Prof Anthony Costello, at the World Health Organization and co-chair of the group behind the new report. It follows a related report in 2009 that warned that climate change was the biggest danger to global health in the 21st century, an assessment repeated in the new report.

But Costello said acting to halt global warming would also deliver a huge benefit for health: “The outlook is challenging, but we still have an opportunity to turn a looming medical emergency into the most significant advance for public health this century.”

“Our scientists have been telling us for some time that we’ve got a bad case of climate change. Now our doctors are telling us it’s bad for our health,” said Christiana Figueres, who as the UN’s climate chief negotiated the Paris climate change agreement and also co-chaired the new report.

“Hundreds of millions of people are already suffering health impacts as a result of climate change,” she told the Guardian. “Tackling climate change directly, unequivocally, and immediately improves global health. It’s as simple as that.”

One of the most striking of the 40 indicators assessed by the researchers was a huge increase in the number of people over 65 exposed to extreme heat. This rose by 125 million between 2000 and 2016 and worries doctors because older people are especially vulnerable to heat.

“There is no crystal ball gazing here, these are the actual observations,” said Prof Peter Cox, at the University of Exeter, UK. He said the 70,000 deaths that resulted from the 2003 heatwave in Europe looked small compared to the long-term trends: “We were alarmed when we saw this.”

Most of the increase in exposed people resulted from rising temperatures, but the number of older people is also rising, creating a “perfect storm”, Cox said. The report also found that hotter and more humid weather was increasingly creating conditions in which it is impossible to work outside. In 2016, this caused work equivalent to almost a million people to be lost, half in India alone.

The report also found that climate change has increased the ability of dengue fever to spread, because the mosquitoes and the virus they carry breed more quickly. Dengue is also known as “breakbone fever” due to the pain it causes and infections have doubled in each decade since 1990, now reaching up to 100 million infections a year now. Dengue was used as an example in the report and the researchers suggest global warming will also increase the spread of other diseases such as schistosomiasis.

Air pollution is known to cause millions of early deaths every year but the new report highlights the 800,000 annual deaths related solely to coal burning. The good news here, said Prof Paul Wilkinson, is that coal production peaked in 2013 and is now falling. “We are seeing the first turn [in the trend] but we have a long way to go,” he said. “It is a health dividend we are ignoring if we do not act.”

The impacts of climate change are not limited to poorer nations, said Dr Toby Hillman, at the Royal College of Physicians, but also affect developed nations like the UK. He said air pollution kills about 40,000 in the UK each year and criticised low government funding levels for cycling and walking. Hillman also noted other impacts, such as sharp increases in mental health problems after extreme weather events like flooding.

The new report highlighted imminent threats as well, such as the loss of crops to increasingly hot and extreme weather. “We are going to see millions more undernourished children as a result of that,” said Prof Hugh Montgomery, at University College London (UCL).

Montgomery said the potential benefits of climate change appeared to be small in comparison to the damages: “We are not ducking the potential benefits, we just find it hard to see what they are.”

Cox said it was not clear that global warming will actually reduce winter cold spells, which cause early deaths in higher latitude countries, because changes happening in the Arctic can exacerbate cold snaps. Prof Georgina Mace, also at UCL, said the evidence for a warmer climate increasing food production was often very localised and short term: “Overall the overwhelming pattern is negative.”

Clare Goodess, a climate researcher at the University of East Anglia and not part of the Lancet report, said: “The indicators reveal some stark warnings for human health, as well as some glimmers of hope, [and] the key messages appear robust. The attribution of [climate change] temperature trends to human activities is now unequivocal, so the urgency of addressing the issues raised by this report is not in doubt.”

India’s Essel Infra To Sell 685 Megawatts Of Solar Power Assets

Another Indian company which has a substantial renewable energy portfolio is looking to sell off its solar power assets.

Essel Infraprojects, part of the Essel Group, is looking for buyers for its 685 megawatts of solar power capacity, which forms nearly 50% of its overall renewable energy portfolio of 1,400 megawatts. While the company has not specified the reason for this planned sale, it joins several others who have either already sold off or are looking to offload their solar power assets.

Another important commonality in Essel Infraprojects and other sellers is that they are not core power generation companies or renewable energy project developers. Essel Infraprojects has diversified interests and assets in power transmission, transportation, and waste management.

The company currently operates six solar power projects with another six under construction. Several of these projects were won in competitive auctions under central or state governments. It is unclear about the future of other renewable energy projects of the company.

In early 2016, the company had committed to have an operational renewable energy capacity of 12 gigawatts including 7.5 gigawatts of solar, 4 gigawatts of wind, and 500 megawatts of waste-to-energy projects. The company also signed an agreement with the government of Rajasthan to set up a 5 gigawatt solar power park; no details or developments have been recently reported in this matter.

possible reason for selectively selling off solar power assets could be the sharp fall in solar power tariffs due to increased competition and fall in solar power modules prices. The increased competition has led to a mad race to the bottom which saw tariffs fall by 86% since 2010. At present the lowest solar power tariff in India is Rs 2.44/kWh (3.7¢/kWh).

Norwegian Firm Signs Deal For 2 Gigawatt Solar Project In Iran

At a time when the future of the Iran nuclear deal seems uncertain, European companies are pushing forward with renewable energy cooperation with the Middle East country.

Norwegian solar modules manufacturer Saga Energy has reportedly signed an agreement with Iran’s Amin Energy Developers for setting up a 2 gigawatt solar power project. The total value of the deal is estimated to be $2.9 billion. Few details are available about the agreement, but the project is likely to be operational in five years.

This is the second Norwegian company to have signed a solar project development deal in Iran. In September this year, Scatec Solar signed an agreement to set up 500 megawatts of solar power capacity in Iran in a phased manner. The first phase of the capacity addition entails the implementation of 120 megawatts of capacity at an estimated cost of $120 million per 100 megawatts.

The country’s total installed power capacity is 77,000 megawatts. In order to diversify its power mix, Iran aims to have more than 5000 megawatts of renewable energy facilities by 2022, which would include 4,500 megawatts of wind power and 500 megawatts of solar power, according to the Renewable Energy Organization of Iran.

Ever since Iran signed up to the nuclear deal that placed restrictions on its nuclear program, several European companies have raced to set up renewable energy projects in the country. At least the interest shown by the the European countries for renewable energy investment in Iran put the country in sync with the rapid renewable energy developments seen in regional neighbors like Saudi Arabia, United Arab Emirates, and Jordan.

Speaking of the Middle East region, a recent study by the Lappeenranta University of Technology in Finland showed that Iran can play a major role in the development and implementation of a pan-Middle East renewable energy grid. This regional grid would be significantly cheaper than nuclear or fossil fuel+carbon capture systems.

Macquarie Plans Entry Into India Solar Power Market

After investments in India’s thermal power market, Macquarie Asia Infrastructure Fund (MAIF) is now planning entry into India’s rapidly growing solar power market.

According to media reports, Hindustan Powerprojects Limited is planning to sell off some of its solar power assets to MAIF as the former looks to expand its solar base globally. Hindustan Powerprojects confirmed the development to an Indian business daily.

Hindustan Powerprojects has less than 300 megawatts of operational solar power capacity in India with an additional 150-200 megawatts under construction. The company is reportedly looking to sell off around half of the operational capacity to MAIF.

This is yet another instance of Indian developers looking to sell equity stake or entire assets to interested buyers to raise funds for further capacity expansion. In this case, Hindustan Powerprojects already has a substantial footprint in developed markets like the United Kingdom, Germany, Italy, and Japan. These international markets will now be the focus of the country as competition in the Indian market has increased substantially. The company has set a target for 2 gigawatts of operational capacity in overseas markets by 2022.

Through this acquisition Macquarie will make an entry into the Indian solar power market. The advantage that Macquarie would get from Hindustan Powerprojects is that the company was among the first entrants in the Indian solar power market.

The company commissioned India’s first utility-scale solar power project even before the National Solar Mission was announced in 2010. Solar power tariffs at that time were as high as Rs 17.91/kWh (27¢/kWh). It also has projects in Gujarat, again with substantially high tariffs compared to the current tariffs.

It is, however, unclear which projects Hindustan Powerprojects will sell to MAIF under the proposed transaction. Still, with power projects tied up with state and central government-owned companies, the revenue is somewhat assured for the next 20-25 years.

Global Solar Market Demand Expected To Reach 100 Gigawatts In 2017, Says SolarPower Europe

European solar industry association SolarPower Europe has published a new analysis predicting that global solar market demand will reach 100 gigawatts for the first time ever this year, a 30% growth from 2016 levels.

SolarPower Europe, the region’s member-led solar association, published its latest market analysis for annual global solar power demand, which it predicts will reach 100 gigawatts (GW) for the first time ever in 2017. This represents a 30% growth from 2016 solar power demand levels when 76.6 GW was connected to the grid.

“It is good to see the growing deployment and political support for solar power, the most versatile and clean form of energy that is now also the lowest-cost for power generation in most countries of the world,” said Michael Schmela, Executive Advisor and Head of Market Intelligence at SolarPower Europe.

This is not the first time that analysts have predicted 2017 solar demand levels will near or reach 100 GW this year, but this late in the year the validity of the prediction grows. In July, GTM Research predicted that global solar power demand would exceed 80 GW for the first time, whereas in September EnergyTrend published an analysis which predicted China’s demand would help push total global demand over the 100 GW mark.

Published this week, SolarPower Europe’s new analysis predicts that China alone has already installed around 42 GW worth of new solar capacity in the first nine months of the year, and will likely add more than 50 GW for the whole year — a 45% growth over the 34.5 GW installed during 2016. Europe and Japan are both expected to add at least 7.5 GW in 2017, the United States around 12 GW, and India around 10 GW.

“In just two and a half years, the average prices in German auctions for solar power have decreased by nearly 50% to only 4.91 euro cents per kWh — and in Spain solar just won an impressive 4 GW in the national clean energy tender,” said Thomas Doering, Policy Advisor and analyst in SolarPower Europe’s Market Intelligence Team. “The time has never been better to invest in solar in Europe and beyond.”

“Solar is the fastest growing source of new energy and the most popular energy technology amongst Europeans,” added James Watson, CEO of SolarPower Europe. “This serves as a reminder to European policymakers to raise their solar ambitions. On the EU level we need at least a 35% renewable energy target by 2030. If we take advantage of this opportunity, we will see more jobs and investments in solar across the continent, and in turn, solar demand will grow again in Europe.”

China Declares War On Polluters — Shutters 40% Of Factories

China is getting serious about curbing pollution. According to sources, up to 40% of its factories have been closed at least temporarily recently as the country has struggled to meet its year-end pollution reduction goals. Officials from more than 80,000 factories have been charged with criminal offences for breaching emissions limits over the past year.

“[B]asically, you’re seeing these inspectors go into factories for surprise inspections,” supply chain consultant Gary Huang from 80/20 Sourcing tells NPR (h/t Futurism). “They’re instituting daily fines, and sometimes — in the real severe cases — criminal enforcement. People are getting put in jail.”

How is the crackdown affecting China’s sprawling manufacturing sector? The government says total output will not be affected, but it is hard to see how the stepped up enforcement could fail to have a negative economic effect.

In prior years, factory shutdowns only lasted a few weeks at most, but environmental protection minister Li Ganjie says the number and length of closures this year is “unprecedented.”

“For those areas that have suffered ecological damage, their leaders and cadres will be held responsible for life,” Yang Weimin told the New York Times recently. He is the deputy director of the Communist Party’s Office of Financial and Economic Affairs. “Our people will be able to see stars at night and hear birds chirp,” he promises.

At the Communist Party annual congress this week, China announced that it plans to reduce the amount of fine particulate matter (that’s the stuff in the air that is less than 2.5 microns in diameter, which is small enough to cross over into the bloodstream from the lungs) from 47 micrograms per cubic meter in 2016 to 35 micrograms per cubic meter by 2035.

“It will be very difficult to reach the goal, and we need to make greater efforts to achieve it,” Li says. “These special campaigns are not a one-off, instead it is an exploration of long-term mechanisms. They have proven effective so we will continue with these measures.”

The tougher enforcement of pollution laws is putting pressure on China’s industrial sector, which will need to adapt by instituting better, smarter, and safer ways of doing business.

“It’s a huge event. It’s a serious event. I think many of us here believe it will become the new normal,” exporter Michael Crotty from China-based MKT & Associates told NPR. “The consumers of China don’t want red and blue rivers. They don’t want to see grey skies every day.”

Unlike the United States, where polluters are rewarded with generous government subsidies at taxpayer expense, China is determined to do what is necessary to protect its citizens from environmental harm. Some would call that leadership.

Carbon Intensity of Global Economy Falls, but not Fast Enough

The carbon intensity of the global economy is falling faster than ever before, but the pace of change is still not enough to hit global climate targets, new research published by PwC warns today.

In 2016 the carbon intensity of the world’s economy fell 2.6 per cent, a continuation of the “step change” in the pace of decarbonisation seen since 2014.

But according to the latest Low Carbon Economy Index (LCEI), which tracks G20 countries’ efforts to reduce the carbon intensity of their economy, progress still falls well short of the 6.3 per cent rate needed to deliver emissions cut compatible with keeping temperature increases to under 2C.

Some countries actually increased the carbon intensity of their economies in 2016 – Indonesia, Argentina, Turkey and South Africa all saw emissions rise faster than their economies grew.

And although nations such as the US, Australia and Mexico did manage to cut their emissions intensity faster than the global average, only China and the UK cut their emissions in line with the two degrees goal. They reduced their emissions intensity by 7.7 per cent and 6.5 per cent respectively, mainly by cutting coal consumption and boosting energy efficiency.

“As countries prepare to discuss the process for raising the ambition of their national targets at the next round of climate talks in Bonn next week, our report emphasises the fact that the Paris Agreement will only be possible if they are serious about accelerating action,” Jonathan Grant, director of climate change at PwC and co-author of the report, said in a statement.

Emerging economies – the so-called ‘E7’ group of China, India, Brazil, Mexico, Russia and Turkey – together cut their emissions intensity at a faster rate of 4.2 per cent, while the G7 nations lagged behind with an overall emissions intensity cut of 2.9 per cent.

The widening gap between the worst and best performing countries poses a serious problem for business, Grant warned. “Companies are being encouraged by investors and others to assess the risks of two degrees scenarios,” he said. “But they’re not forecasting or planning on a two degrees outcome, because the signals from governments just aren’t there right now.”

“Despite the increase in carbon pricing regulation in countries around the world, the price signal is often too feeble to prompt significant low carbon investment,” he continued. “Many companies are now planning for a range of potential outcomes including an increase in extreme weather and other climate impacts.”
