Germany Sets New Renewable Energy Record

Germany has broken another renewable energy record, with clean power providing a third of of the country’s electricity in 2017.

Preliminary data from the Association of Energy and Water Industries show that renewable electricity generation grew to a record 33 percent this year, up from 29 percent in 2016.

“The figures show impressively that there is already an accelerated shift in power generation from CO2-intensive to low-carbon and almost CO2-free energy sources,” Stefan Kapferer, the chairman of the association, said.

“The energy industry is clearly on course with regard to energy and climate targets: our industry is able to reduce CO2 emissions by 40 percent by 2020 compared to 1990.”

Onshore and offshore wind power has now surpassed natural gas, nuclear, and hard coal as the second largest electricity source, with a 16 percent slice of Germany’s power mix.

Germany often makes headlines for its impressive renewable power achievements.

On especially windy and/or sunny days, German power operators are sometimes forced to pay customers to take electricity from the grid.

Most recently, thanks to low demand, unseasonably warm weather and strong breezes, power prices went negative for much of Sunday and the early hours of Christmas Day, the New York Times reported. This is now the second Christmas in a row with two days of negative spot power prices.

Still, there’s room for improvement if Germany wants to meet the goals of its ambitious “Energiewende,” or sustainable energy transition. The country’s power supply still largely relies on lignite, aka brown coal, which generated about 23 percent of Germany’s electricity this year.

Trina Solar Suspends Plans For 1 Gigawatt Solar Fab In India

The world’s largest solar module manufacturer has suspended plans set up a fabrication facility in one of the fastest growing markets – India.

The head of sales for Trina Solar in India recently confirmed that the company has shelved plans to set up a 1 gigawatt solar module manufacturing facility in the country. Gaurav Mathur stated over capacities in the global solar modules market as the reason behind this decision. While this assertion may be true for the overall global market, it does not hold ground in India, especially with the massive expansion in installed capacity planned by the Indian government.

India plans to auction at least 74 gigawatts of solar power capacity between January 2018 and March 2020, or 2.7 gigawatts capacity every month, on average. Compare this with the installed annual solar module production capacity in India of 5 gigawatts and you’ll understand the huge gaping hole that needs to be fixed from the production side.

Trina Solar had planned to set up a 1 gigawatt production facility in the state of Andhra Pradesh. The project was announced following a policy push (Make In India) by the central government to encourage investment in the manufacturing sector. However, at least the solar module manufacturers are yet to see a clear policy that offer incentives for production solar cells or panels. So, after waiting for two years, Trina Solar found it prudent not to pursue its production facility plans, or it could be a way to pressure the government to move swiftly on the policy front.

“We are willing to manufacture in India, provided we get some kind of benefit, specifically for solar industry. It is only a matter of time. We will set up (the manufacturing unit) provided we have the right kind of policy support from the government,” Mathur said.

The prospect of a planned $400-500 million investment from a foreign company being jeopardized may very well push the government to act swiftly on its solar manufacturing policy. Already, the Ministry of New & Renewable Energy is planning to implement an auction policy for setting up solar equipment manufacturing facilities. According to media reports, the government may float tenders to set up 20 gigawatts of solar equipment manufacturing capacity.

It is unclear if Trina’s decision is a reaction to this policy change news, as such auctions would only increase competitiveness in the market.

Northborough-Southborough Public Schools Investigate the Use of Solar Energy

Since July 2016, the Northborough-Southborough Public School system has been investigating the feasibility of solar energy within their district.

“We have moved forward in a very collaborative way with our town,” shared Superintendent Christine Johnson.

The towns and the three collective school committees began the process of exploring the benefits of “going green,” one of which is to send an educational message to their students.

“We believe it important to be a good economic consumer and a good energy consumer so we put together the Request for Proposals (RFP),” Johnson noted.

The RFP process resulted in the selection of Tighe & Bond, an engineering and environmental consulting firm, to do a comprehensive study (Phase I). They presented their findings this fall which detailed preliminary information. Johnson reported that they liked what they learned and that there was the potential for some impressive returns that the towns would gain by following through with this concept.

The project has been broken into phases and Phase II will delve deeper into the various sites that will have the higher levels of return for cost savings. This phase will include the Request for Quotes (RFQ) from solar providers. The towns would lease the solar equipment rather than purchase which would alleviate any capital outlay.

Tighe & Bond’s Feasibility Study consisted of roof top and parking lot canopy solar units. Phase II will include structural analysis to determine the most viable sites within the school district’s 10 buildings, and Phase III will include equipment procurement and contract negotiation to move forward.

There are pluses and minuses to both types of solar units. The advantages of roof-mounted solar panels include streamlined aesthetics, optimization of space, fortification of roofs and greater speed of installation. Negatives include spatial limitations, orientation to the sun, age and condition of the roof, and zoning restrictions.

Parking lot canopy units are becoming more popular as roof and ground sites become scarce. They also provide secondary benefits such as heat reduction in summer and protection from weather elements. However, there is concern over difficulty in the winter with snow plow maneuverability.

Out of the ten buildings initially evaluated, these schools have been selected for further study: Lincoln Street, Fannie E. Proctor, Marion E. Zeh and Marguerite E. Peaslee elementary schools and Robert E. Melican Middle School. Some were better candidates for roof structures while others were best suited for parking lot canopies. Peaslee and Melican need roof repairs.

Using a cumulative 124,000 kilowatt hours (kWh) of electricity per month at a cost of approximately $20,678 during the study period, renewable energy projects provide savings while stabilizing operating costs. For example, Lincoln Street School would see 119 percent energy savings.

As Phase II progresses, towns will analyze the information and opportunities for public input will occur. There will also be an educational component for students to track energy consumption and calculate costs and savings as part of their curriculum.

“This is a big project and it shows students that we are proactive in terms of being environmentally aware,” Johnson said. “It shows the taxpayers that we are trying to save money and it shows we are trying to be 21st-century ready.”

Plastic Trash Used In Construction Materials In Coastal Kenya — To Save Sea Turtles, Nature, Tourism

Photo: Pixabay
Photo-illustration: Pixabay

The coastline of Kenya has been a hotspot for tourism and fishing activities for a quite a while now — with the region also being home to fair numbers of sea turtles. Recent years, though, have made the region home to significant quantities of plastic trash and debris — much of which eventually washes into the sea.

With that reality in mind — and also the effect that such pollution has on wildlife and tourism — a man by the name of Sam Ngumba Ngaruiya has in recent times been working with locals in and around the town of Malindi to gather up and recycle the ubiquitous plastic pollution into construction materials.

The idea is simple: pay locals to gather up plastic debris and pollution, and then repurpose it into useful construction materials (fence poles, roof tiles, road signs, flooring, containers, etc.).

Ngaruiya’s firm, Regeneration Environmental Services Ltd, pays locals 10 shillings for 1 kilogram of plastic (~2 two-liter water bottles). Effectively, according to Ngaruiya, this means that in 4 or so hours, around 50 kilograms of plastic can be collected by those working on this — resulting in earnings of around 500 shillings ($4.86).

That’s roughly “enough to eat and feed their family for a day,” according to Ngaruiya. So, not a bad deal all things considered for those looking to make a living and also help clean up the local living environment.

The gathered plastics are then separated into 8 different types, which are then machine-chopped into flakes around 1-cm in size. These plastic flakes are then rinsed and dried — following which, they are then combined with hardeners and sun-blockers, then heated to around the melting point (avoiding going much higher limits toxic fume creation). Into this heated mass, locally acquired gravel, sand, coconut fibers, sawdust, etc., is added — with the mixture then being poured into already created moulds of the products in question.

“Basically we are substituting plastic for cement,” explained Ngaruiya in an interview with Reuters. The US-trained engineer went on to explain that when the melted plastic cools, it absorbs and “squeezes” the sand, creating a compact and rather strong building material.

“These recycled plastic products can last 200 years,” he continued. So, in other words, arguably the greatest “negative” of plastics — their resistance to degradation and decay — becomes a positive owing to a change of context (construction materials), according to Ngaruiya.

The coverage from Reuters continues: “Kai, a 3-year-old green sea turtle, was released back into the turquoise waters of the Indian Ocean off Kenya’s coast this month. She had been hospitalized after her guts were blocked with white plastic bags she swallowed, mistaking them for jellyfish, and tiny plastic pieces entangled in the sea grass she eats.

“In a bid to clean up Kai’s environment, the villagers of Watamu, who depend on fishing and tourism, joined hands in 2016 with an entrepreneur and a local ocean conservation charity to recycle plastic waste from two marine national parks in eastern Kenya … Villagers in Watamu, including school children, gather plastic waste from the sea, beaches and households every Friday, a holy day for the Muslim-majority community here.”

To date (since work began in 2016), Ngaruiya’s company has recycled around 40–50 tonnes of plastic pollution gathered from nearby areas. With the firm’s recycling plant possessing a daily capacity of around 2 tonnes, there’s certainly still room for growth, but orders for the recycled materials being produced there have remained sparse — despite being “competitively priced,” according to Ngaruiya.

Something very interesting here is that there is no government support backing the work — or support from various agencies, banks, etc. Ngaruiya has put around $500,000 of his own money into the project.

Kenya, as you may remember, actually went ahead and banned single-use plastic bags earlier this year because of the environmental problems associated with them, so the recognition that plastic pollution is a problem is there, but direct support for Ngaruiya’s project is nonexistent.

Ngaruiya noted that there likely needed to be a change at the consumer level for real change to come about: “It’s time to take personal responsibility with one’s own waste, to separate the organics from the plastics, and ensure they reach the recycling centers.”

He added that there needed to be many more facilities like his along the coast of Kenya to better deal with the problem.

To provide more context here, tourism in Kenya has fallen considerably in recent years, particularly with regard to coastal regions. The official line on the matter is that Islamist groups have created a security issue in the region. Other opinions exist, though, with a notable one being that the growing pollution problems scare tourists away.

A currency exchanger in Watamu by the name of Ben Kithiy was quoted as saying: “Floating plastic pieces sticking to the body when you are swimming in these waters makes for a very unpleasant experience.”

He added that even local children didn’t like swimming at the beaches much anymore as a result.

Kithiy also explained that over the last year he has found 5 rotten dead turtles on just his local beach in Blue Lagoon Bay; with many others also seen floating lethargically in shallow waters after consuming plastic debris (most of which likely starved). Obviously, such sights aren’t likely to draw in tourists looking for a vision of “unspoiled paradise.” (The fact that tourism, and international wealth pumps in general, are directly associated with such pollution is seemingly lost on many people.)

The head of the local Watamu Turtle Watch conservation program, Casper Van De Geer, explained to Reuters that around 15% of the turtles brought in for rehabilitation every year were directly harmed by the ingestion of plastic.

He stated: “Close to half of them die of infection as pieces of hard plastic lodge into nooks and crannies inside the intestine, lacerating it and causing infection.”

Hopefully, attitudes and initiatives similar to Ngaruiya’s become more common over the coming years. If ecological collapse is to be avoided, then such a shift will be a necessity.

Indian State Of Karnataka Announces 860 Megawatt Solar Tender

Photo: Pixabay
Photo-illustration: Pixabay

India’s fifth largest state in terms of operational solar power capacity has recently launched a huge tender to further expand its solar power infrastructure and meet the renewable purchase obligation.

Karnataka Renewable Energy Development Limited, a state government agency, recently issued tender documents for 860 megawatts of solar PV power capacity. The capacity will be allocated in blocks of 20 megawatts each across 43 locations in the state.

Interested bidders will be allowed to bid for as low as 3 megawatts per site. It is unclear as to why the state government chose to distribute the solar power projects across the state. Projects at a single location, like a solar park, tend to have lower capital cost investment as multiple power plants can share transmission and other basic infrastructure.

A possible reason for the state-wide distribution could be to insulate the transmission and distribution network from sudden fluctuations in solar power generation. In fact, the government had earlier cancelled a tender for 750 megawatts due to lack of adequate transmission infrastructure. A part of this cancelled capacity has been re-tendered.

Karnataka is host to perhaps the largest solar power park planned in India. The Pavagada solar power park is expected to have an eventual installed capacity of 2,700 megawatts. Auctions for a substantial capacity have already taken place with some projects also commissioned.

The state, which plans for 6,000 megawatts of solar power capacity operational by March 2022, clearly does not want all of its solar assets concentrated at one place and has thus decided to distribute the projects across districts.

It is heartening to see states taking initiative to push India’s solar power target of 100 gigawatts by March 2022. The central government recently announced plans to have 74 gigawatts of solar power capacity auctioned between January 2018 and March 2020.

An Argentine Startup Makes Shoes from Discarded Tire Scraps and Employs Single Mothers

Photo-ilustration: Pixabay
Photo-illustration: Pixabay

More than 100,000 tons of rubber tires are disposed of every year in Argentina. The majority of them are burned, contributing to the country’s already huge air pollution problem. So, when Alejandro Malgor and two of his friends, Ezequiel Gatti and Nazareno El Hom, realized they wanted to start a business, they decided to focus on tackling the problem — and make shoes from the discarded tire scraps.

But the trio didn’t stop at tackling environmental issues; they wanted to generate opportunities for the unemployed, and particularly single mothers, in their hometown of Mendoza.

“The garbage we generate creates opportunities for everyone,” Malgor explains.

Xinca currently employs 25 women from rural areas, where much of the production is done. Malgor says he is committed to working with local communities and enabling single mothers to remain heads of their families by providing them with employment opportunities.

This is part an Across Women’s Lives project: Wear and Tear series: The women who make our clothes.

“We like people and companies who buy our products to know they are helping empower women and people excluded by the system,” he says.

Although Argentina has finally pulled itself out of recession, the gap between poor and rich remains vast, with 50 percent of workers earning less than the minimum wage, and more than 32 percent of Argentinians living in poverty.

Xinca’s main objective is to empower women who don’t have access to education by providing them the training they need to work. Malgor says he and his co-founders want to give women back their dignity by helping them become independent through earning their own income.

“We want to help single mothers because they are so important to society. They are strong women who want to give the best lives for their children, but sometimes they do not have the resources or the tools to do this,” Malgor says.

That’s where Xinca comes in: “We teach the women how to work as a team, how to take responsibility in a job. When they learn new skills, the women get better self-esteem and more confidence. Having a job means they don’t only learn new tools for work but they grow personally, too.”

A 2014 study found around one in four Argentine homes are led by single parents, 72 percent of whom are single mothers.

Mauricia Vargas is one of those women. At 40 years old, she is the mother of two children, and she raises them alone. Before joining Xinca in 2014, she worked in agriculture. The farm work was hard, required long hours and paid little. Xinca offered her a chance to learn new skills and earn more money to support her family.

“For me, having a job means economic help and at the same time, to learn things I like,” Vargas explains. “This opportunity is very good because you are not just learning, you are meeting incredible people in the job and earning money at the same time.”

A 2010 census in Argentina found 1.7 million of the country’s women worked in rural areas. According to the United Nations Food and Agriculture Organization, rural women represent one-fourth of the world’s population and produce more than half the global food supply, but still face economic, social and gender inequality. The FAO identified key problems for rural Argentine women including lack of opportunities for education, training and employment and difficulty in accessing credit and to plan an “autonomous future.”

“The women we employ are women who want to get ahead, who want to improve the quality of life for their children, but who don’t know how to do it,” Malgor says. “So, we generate economic and social opportunities so they can do this for themselves.”

Since launching in 2013, Xinca has already recycled 20,000 kilograms of tires, which are provided by a recycling plant in Argentina’s capital, Buenos Aires. Malgor and his team don’t just focus on recycling tires, either. To make the shoe itself, they collect textile scraps from the fashion industry and have established several partnerships with companies who donate the fabric to Xinca.

“The process starts in the recycling plant, where we separate the metals from rubber,” Malgor explains. “Then, we cut the shoes directly from the tires. For the other part of the shoe, we reuse fabric from the fashion industry. We have partnerships with different brands that want to communicate that they are taking care of their waste.”

Xinca sells its products, which now include backpacks and caps, online as well as through the ethical clothing giant Patagonia. It’s hoping to use the money it won in a 2017 competition, The Chivas Venture, to expand to Australia, Chile and Uruguay. The company currently makes 1,500 pairs of shoes a month.

South Korea Aim: 5 Times More Solar Energy Generation By 2030

The government of South Korea has unveiled new plans for the country to boost its solar energy generation 5 times over by 2030, as revealed by the country’s Minister of Trade, Industry and Energy.

The news follows on earlier campaign promises by the relatively new President, Moon Jae-in — campaign promises to cease support for new nuclear energy projects and to embrace “eco friendly” energy modalities. The new president has more or less kept his word, as the government has now cancelled plans for 6 new nuclear reactors.

That said, South Korea still represents the 5th largest nuclear energy user in the world — with a total of 24 nuclear reactors now active in the country, altogether meeting around a third of its electricity demand.

Commenting on the plans, the Minister of Trade, Industry and Energy, Paik Un-gyu, stated: “We will fundamentally change the way renewable energy is developed by creating an environment where the public can easily participate in the renewable energy business.”

Reuters provides more: “South Korea plans to provide a fifth of the country’s total amount of electricity from renewable energy by 2030, up from 7% in 2016. To meet that goal, it plans to add 30.8 gigawatts (GW) of solar power generating capacity and 16.5 GW of wind power capacity by 2030. As of 2017, South Korea has 5.7 GW of generating capacity from solar power and 1.2 GW from wind power.

“The additional capacity will come from major projects, as well as by converting individual households, farms, and small businesses to renewable energy, the ministry said.”

The government is apparently now aiming for approximately 1 out of every 30 households to be equipped with solar energy systems by 2022. That’s certainly an interesting goal, isn’t it? Quite a divergence from where politics are headed in the great old USA it would seem…

Adnan Bosović: The Balkans Has to Keep up with Europe

Photo: PE Elektroprivreda BiH
Photo: PE Elektroprivreda BiH

Adnan Bosović, the electrical engineer and expert associate for the development of distributive, energy efficient facilities in the Sector for strategic development in PE Elektroprivreda BiH – Sarajevo, has explained to us the situation in Bosnia and Hercegovina regarding ecomobility, how popular energy efficient cars are and also the situation with charging infrastructure.

EP: What is the situation in BiH in terms of e-mobility? What is the percentage of hybrid and fully electric cars?

Adnan Bosović: Year after year, the number of hybrid cars, which have come on the market much earlier, is increasing. However, these vehicles cannot be charged from the grid. PE Elektroprivreda BiH – Sarajevo has recently purchased the first two electric cars in BiH Mitsubishi iMiEV and Volkswagen e‑Golf. I do not have information on the usage of plug-in hybrid cars in BiH. There is also a small number of transformed electric cars.

EP: In your opinion, what is the reason for a small number of these vehicles in wider use?

Adnan Bosović: It is evident that the market for electric cars in BiH is still at a very early stage of development. However, as in other sectors, it is expected that BiH will also achieve the EU’s level of development of the electric cars market with a certain delay. Given the fact that the sales price of the electric cars is still quite high, the key precondition for this is the introduction of incentives.

EP: What are all the obstacles which buyers but also importers encounter when buying electric cars in your country?

Adnan Bosović: So far, two brands which PE Elektroprivreda BiH – Sarajevo has purchased, are present on BiH’s market. Service equipping and training of service’s personnel is being performed only now. Both buyers and importers have difficulties with but the purchase of electric cars due to the limited offer on the market and larger orders in the EU countries. Other obstacles for the general use of electric cars are lack of public and private charging infrastructure and the drivers’ fear of disappearance of energy before reaching their destination due to the limited reach of the existing electric cars.

EP: Do you expect that BiH will soon provide subsidies to importers of electric and hybrid vehicles as well as tax reliefs to the owners of these cars?

Adnan Bosović: I believe that it is necessary to insist on the introduction of different incentives and benefits according to the model of EU countries since this is the key precondition to finally start with the significant sale of electric cars in Bosnia and Herzegovina.

EP: Does PE Elektroprivreda BiH – Sarajevo influence a change in legislation regarding the simplification of electric vehicles’s registration?

Adnan Bosović: Up to this moment it was early to start with this kind of initiatives, but we notice that the public has matured for the progress in this regard, so we hope to see some concrete steps in the near future.

Photo: PE Elektroprivreda BiH

EP: When do you expect for charging infrastructure, that is the network of charging stations to be built in BiH?

Adnan Bosović: There is already a certain number of chargers for electric vehicles in BiH, primarily in the city of Sarajevo. A good part refers to the chargers in car showrooms, that are intended for their own usage. The first public charging station in BiH was installed by the Hotel Residence Inn Marriott in Sarajevo in 2016, but it is intended only for the hotel guests. The first charging station that PE Elektroprivreda BiH – Sarajevo has installed is placed in front of the Directorate building at 15 Vilsonovo šetalište in Sarajevo. The charger is in the function and we expect its promotion soon. Charging will be free of charge for all owners of the electric vehicles until further notice. In the years to come, we will certainly be witnesses of the spread of charging network and charging stations for electric vehicles in BiH.

EP: Does PE Elektroprivreda BiH – Sarajevo plan to connect with international corridors that is to enable travellers from Europe to charge their electric vehicles in BiH without difficulties?

Adnan Bosović: If BiH wants to connect to international corridors on which electric cars will run, the development of high-power DC chargers is certainly an imperative. Of course, we are aware of the importance of these charging stations, but it’s too early to talk about concrete locations and their number.

EP: When do you expect that the things in the Balkans will change for the better and what steps should be taken?

Adnan Bosović: Time passes quickly and the sector of electromobility is rapidly evolving, so the Balkans needs to keep up with Europe, which means that incentives and different tax reliefs should be introduced, then invest into the charging network for electric cars, as well as purchase electric cars.

EP: What number of cars can the existing distribution grid endure?

Adnan Bosović: We have done detailed analyses on the impact of electric cars’ charging on our distribution grid on which basis we have developed several scientific and expert papers. The results show the average percentage of electric cars breakthrough, from which we do not expect major problems, is 5-10 percent. This means that the distribution grid is not an obstacle for the introduction of electric cars. Of course, the problems may occur locally, in certain places, but operators of distribution system have established ways to increase the capacity of their grids. Naturally, for the greater breakthrough of 20-50 percent, the problems are big and much is changed, but on this topic, there are many scientific and expert papers.

Photo: PE Elektroprivreda BiH

EP: What impact on change does your team of innovation experts have in this sector?

Adnan Bosović: Sector for strategic development in PE Elektroprivreda BiH – Sarajevo is among other things in charge with pilot projects and the introduction of new technologies in our company, so our role in the sector of electromobility is thus clear. We carry out our activities with the help of other sectors. For example, the pilot project of the first charging station could not be possible without the Sector for General Affairs and Elektrodistribucija Sarajevo. The development of electric cars’ market will certainly be supported by many other subjects such as car sellers, environmental funds, municipalities, ministries and other institutions.

EP: Since you have recently shown your first electric cars, can you tell us something more about it? What are its characteristics, what battery does it have and what is battery’s capacity? How many kilometers has it crossed so far? Have you thought about installing solar panels on its roof?

Adnan Bosović: So far we have purchased two electric vehicles as part of the fleet of PE Elektroprivreda BiH – Sarajevo. Those are Mitsubishi iMiEV and Volkswagen e Golf. Mitsubishi iMiEV is a small city car for 4 people whose mo‑ tor has the power of 49kW and the capacity of the battery is 16 kWh which allows maximum range of 160 km. Volkswagen e Golf is an electric car for 5 people and the power of the motor is 100 kW, the capacity of its battery is 35.8 kWh and its range is 300 km. For the time being, the Directorate of the company will use them for local tours in Sarajevo. The cars are serially produced so we are not thinking about their refinement in terms of installing solar panels.

Photo: Elektroprivreda BiH

EP: Tell us something about the chargers you are working on, how fast are they?

Adnan Bosović: The first charging station, that we installed was equipped with two Mode3 type 2 connectors, is envisaged for AC charging of 2 vehicles with a maximum power of 2×22 kW. It should be pointed out that the power of AC charging of electric vehicles depends on the power of rectifier in an electric vehicle that is limiting. So, Mitsubishi iMiEV is charging with a power of 3.7 kW at our station and Volkswagen e-Golf with a power of 7.2 kW.

EP: Since you had a chance to drive an electric car, can you describe us your impression?

Adnan Bosović: I had a chance to of course drive our two recently purchased cars, as well as some others during the business visits to the countries in the region. The greatest subjective difference in comparison to the vehicles with manual transmission is that everything is automatic in electric cars. In addition to that, a great acceleration of electric cars has made a powerful impression, but also the fact that they are unusually silent.

EP: Do you have any message for the drivers – pollutants for the end?

Adnan Bosović: The massive use of electric cars is the future and that is something that is already happening in developed countries all around the world. The selling price is still relatively high, but it will definitely fall with greater mass production and with the development of technology. The introduction of incentives makes these cars more affordable to ordinary people and thus we need to insist on their introduction in the countries of our region.

India Plans 5 Gigawatt Offshore Wind Auction In 2018

After delay of several years, India may eventually auction and allocate its first-ever offshore wind energy projects next year.

The Minister for New & Renewable Energy, RK Singh, recently told media outlets that at least 5 gigawatts of offshore wind energy capacity could be auctioned in 2018. Feasibility study on one of the proposed sites is in progress while a similar survey would begin at two more sites soon, Singh added.

India plans to auction 10 gigawatts of wind energy capacity each in 2018 and 2019 to reach a total installed capacity of 60 gigawatts by March 2022.

The talks of survey for offshore wind energy projects in India date back to 2010. The Centre for Wind Energy Technology (now the National Institute of Wind Energy) was reported to undertake a 2- to 3-year feasibility survey along India’s coastline. Either those surveys were never undertaken or the new surveys are being conducted at a higher hub height to correspond with the current technology available.

The National Institute of Wind Energy (NISE) had upgraded India’s onshore wind energy potential from 49 gigawatts at 50 meters hub height to 103 gigawatts at 80 meters hub height and eventually to 302 gigawatts at 120 meters hub height. A similar upgrade in the offshore wind energy potential may have delayed the government’s plans.

The Ministry of New & Renewable Energy, along with other arms of the government, approved the offshore wind energy policy in 2015. While there have been no auctions for offshore wind energy projects, Suzlon Energy — one of India’s leading wind energy solutions providers — was reportedly working on a 600 megawatt project in the state of Gujarat. No recent updates on the project are available.

The news of a potential auction would be music to the ears of companies like Suzlon Energy, Vestas, and Senvion which are operational in India and would be front-runners to supply technology to project developers who bid for the projects.

Flying cars seem to be moving from the realm of science fiction to reality – and Richard’s Architecture + Design (RA+D) helmed by architect Richard Moreta Castillo has already designed a net-zero tower pioneering drone car infrastructure. The Smart Power Long tower, a condominium building planned for Shanghai, features landing pads for flying cars. The futuristic concept is super green, according to RA+D, and will feature a vertical forest in which 50,000 trees and shrubs could scrub the skies.

Dubai started testing flying taxis earlier this year, and RA+D also pointed to Nevada officials seeking permission from the Federal Aviation Administration for flying passenger drones as evidence the futuristic vehicles could soon be soaring the skies. RA+D first came up with the drone car tower concept in 2015 with their Moscow Tower, and they said the Shanghai tower’s construction could occur faster than expected – between 2018 and 2020.

The condominium tower draws design inspiration from Chinese dragon art. Docking stations for drone cars wind up the exterior. The building could clean the air naturally, as plants take in carbon dioxide, and could also have 180 carbon dioxide extractors, according to RA+D. The air could then be expelled from the top in numbers corresponding with the hour, illuminated with an LED spotlight to create an appearance similar to fire, to create what RA+D described as the “first smoke and chromatic clock for the reference of the Shanghai community.”

Clean technologies are also part of Smart Power Long’s design, such as a recycling water plant utilizing ultraviolet disinfection treatment. A vertical electrical power plant will draw on solar, wind, hydro, and geothermal energy. The multi-use building could also contain a convention center, water river biology laboratories, and residences.

Smart Power Long is designed for Shanghai’s Pudong District with a budget of $600 million.

An ultra-fast electric vehicle (EV) charging station that just opened in Germany could offer upcoming models of EVs a range of 100 kilometers, or around 62 miles, in a snappy five minutes. It’s the first public station with the super fast chargers in Europe. Four cars can be charged at the same time at the Ultra-E station right now at rates of 175 kilowatts (kW) – with 350 kW coming soon.

Two different ultra-fast EV charging networks are springing up across Europe right now, according to Electrek; the one that just went online is from Ultra-E, backed by partners like BMW, Audi, Renault, and the Netherlands-based Allego, which is equipping a corridor with 21 ultra-fast stations from the Netherlands to the Austrian border.

Allego COO Ulf Schulte said in a statement, “We are delighted to be setting a milestone for future elctro-mobility in Europe with this new generation of fast chargers.”

These ultra-fast chargers are located in Kleinostheim close to the A3 motorway, at the Aschaffenburg-West exit on Saaläcker Strasse. Two of the four ultra-fast connections will be offering charging at rates of 350 kW in the spring – although Electrek pointed out no EV can currently charge at that rate yet. Schulte said, “We support all the current charging cards and access apps, enabling anyone to charge their e-car at Allego and quickly be on their way.”

More Ultra-E charging stations will be popping up soon, every 150 to 200 kilometers or so – that’s around 93 to 124 miles – near motorway exits. The next one is planned for Bernau am Chiemsee in Southeast Germany.

Electrek said the other up-and-coming charging network is Ionity, a joint venture of Daimler, BMW, Ford, Volkswagen, Porsche, and Audi. They announced in late November they’ve secured site partners for 18 countries in Europe.

India auctioned off 750 megawatts of utility-scale solar power capacity over the last few days to wrap up a highly eventful 2017 that saw new records being created in terms of tariffs.

The famous Bhadla solar power park in the Indian state of Rajasthan is in the news once again. The Solar Energy Corporation of India auctioned 750 megawatts of solar power capacity at this solar power park. Interestingly, while the projects will be located in Rajasthan, the power generated will be acquired by the neighboring state of Uttar Pradesh.

There were two separate auctions of 500 megawatts and 250 megawatts. The first auction of 500 megawatts was oversubscribed 6 times over with interested developers submitting bids for 3.1 gigawatts. The tariff bids were between Rs 2.47/kWh (3.80¢/kWh) and Rs 3.29/kWh (5.07¢/kWh). While the viability gap funding (capital support by the government) was on offer, none of the developers opted for it.

Hero Future Energies secured 300 megawatts of capacity at Rs 2.47/kWh (3.80¢/kWh) and SoftBank-backed SB Energy won rights to develop 200 megawatts at Rs 2.48/kWh (3.81¢/kWh); SB Energy had actually placed bid for 500 megawatts of capacity.

Other major developers that submitted bids but failed to make the cut in this auction include Actis Energy, Azure Power, Canadian Solar, ReNew Power, EDF, and Solairedirect. Acme Solar, too, participated in the auction and quoted Rs 3.03/kWh (4.67¢/kWh) for 300 megawatts of capacity. Interestingly, this bid is 24% higher than the bid Acme had placed in May 2017 in a similar auction for a project in the Bhadla solar power park. That May 2017 bid of Rs 2.44/kWh (3.7¢/kWh) remains the lowest-ever tariff for a solar power project in India. Acme is expected to launch an initial public offering to raise funding for this project.

The second auction for 250 megawatts of capacity also witnessed huge participation from project developers. Prospective developers placed bids for 1,350 megawatts, translating into an oversubscription of 5.4 times.

Azure Power and ReNew Power Ventures secured rights to develop 200 megawatts at Rs 2.48/kWh (3.88¢/kWh) and 50 megawatts at Rs 2.49/kWh (3.89¢/kWh), respectively. Three companies — ReNew Power Ventures, SB Energy, and FRV Solar had placed bids to set up the entire 250 megawatt capacity. Other bidders included Actis Energy, Hero Future Energies, Canadian Solar and EDEN RE.

Power generated from this 750 megawatt capacity will be acquired by Uttar Pradesh, which has not seen such low tariffs in its own solar power auctions. Uttar Pradesh utilities recently signed power purchase agreements for solar power at Rs 7.02/kWh (11¢/kWh). The power supplied to Uttar Pradesh from the Bhadla solar power park will now come at additional cost as the central government has exempted inter-state transmission of solar power from any charges.

Uttar Pradesh had expressed interest in the procurement of power from Bhadla-based solar power projects after the May 2017 auction at the solar park that yield record-low tariff of Rs 2.44/kWh (3.7¢/kWh). Delhi Metro Rail Corporation has already signed a similar agreement to acquire around 200 megawatts from Rewa solar power park located 800 kilometers away in the state of Madhya Pradesh. Indian Railways eyes a similar arrangement in the near future.

The Mucomir small hydropower plant in Scotland is now back on the grid, following the modernization of equipment at the plant, technology group Voith has announced.

Operated by SSE, the upgraded project was commissioned back in the autumn and is now operating with improved cost efficiency and meets the strictest environmental standards.

For this project Voith was responsible for the new build, installation and commissioning of the turbine unit, installation of a control system, circuit breaker and hydraulic unit, and for refurbishing the generator.

“The modernization work was done during a shutdown, and because of the tight schedule, the fabrication and installation of the components were a major challenge,” explained Christian Merkl, Project Manager of Voith Hydro Germany. “However, thanks to our experience and our close cooperation with plant operator SSE, we were able to complete the project no less than three weeks ahead of schedule.”

The special design of the new turbine runner reduces adverse effects on fish and makes it easier for them to pass through it. This means that SSE is taking regional fishery interests into account and acknowledging the importance of the power plant for migratory fish in the local catchment area. In addition, as part of the upgrade, oil and grease-free bearings were installed to avoid environmental damage.

Peter Diver, Programmes Manager at SSE, says of the project: “The modernization of the Mucomir hydropower plant ensures the commercial viability of the facility while taking account of ecological factors and using the most effective technological solution. We are delighted to have implemented this important project with Voith as our partner.”

Following the upgrade, the Mucomir plant qualifies for feed-in tariff – resulting in improved remuneration for the power station and was an important part of the business case, securing the station for the future. As well as improved protection of fish and the environment, the use of ultra-modern developments in the hydraulic system also achieves greater efficiency. Moreover, the power plant is now equipped with a remote control system ensuring safe and efficient unmanned operation that also allows fast fault analysis where necessary.

Power Potential of Renewable Energy Sources Being Harmed by Climate Change

Climate change is affecting wind energy’s potential to provide power, diminishing a renewable energy source that scientists and policymakers are counting on to replace fossil fuels, according to two scientific studies.

The world is turning more and more to renewable sources of energy — wind, solar power, and in some cases energy from flowing water — to fight climate change. But what if climate change itself alters the distribution of wind, or sunlight falling on the Earth’s surface, or river flows, and so changes or even shrinks the potential of these energy sources?

The studies suggest that, at least for wind energy, that is not only happening — at least in some key locations — but that it could grow worse.

“Renewables, including wind, are an important part of many nations’ and even states’ overall strategies for reducing greenhouse emissions,” said Kristopher Karnauskas, a researcher at the University of Colorado, and first author of one of the studies. “So it’s important that we fully understand how the potential efficacy of that mitigation strategy may be changing concurrently with the problem itself. We can’t assume that the baseline wind energy resource is a constant.”

Why would wind energy potential change because of climate change? At the most fundamental level, winds are driven by the unequal distribution of the sun’s energy across the surface of the Earth, which in turn creates regions of different atmospheric pressure. Wind then flows from regions of high pressure to regions of low pressure. Those installing wind turbines try to place them in spots where that flow tends to be particularly strong.

But climate change is also distributing energy unevenly across the planet. In particular, land surfaces are warming up more rapidly than are ocean surfaces, even as the Arctic is warming up much more rapidly than the northern hemisphere’s middle latitudes.

It’s not surprising that the distribution of winds around the Earth would change under global warming. Indeed, in the Southern Hemisphere, some researchers believe that changing winds are responsible for the growing melting of Antarctic glaciers, as they are driving warmer, deeper waters closer to the icy continent.

So how could changing wind patterns affect the deployment and effectiveness of wind energy?

The first of the two studies, recently published in Nature Scientific Reports, gives a first glimpse at an answer. It finds that the nation that has installed more wind energy than any other on Earth — China — is actually seeing a lowering of wind energy potential across vast regions, especially inner Mongolia and Gansu, two of the largest installation areas.

“To my great surprise instead of finding a random signal, we found that it was actually declining,” said Michael McElroy, a Harvard Earth sciences professor who is one of the authors of the study. He conducted the research with Peter Sherman, the first author, and Xinyu Chen of Harvard.

The researchers found, based on a large database of meteorological records, that there already has been a wind energy decline in key regions of China from 1979 through 2015. And they found that this had happened in concert with an overall warming trend, although natural climate fluctuations also played a role.

The change occurred, McElroy said, because the Asian continent has been warming up faster than the Pacific Ocean offshore.

Solar Panels Are Replacing Diesel Fuel in Canada’s Far North

The sun being a resource worth tapping into is now globally accepted, but how to do it in the most efficient way is still an ongoing conversation. The obvious choice is to put solar panels in regions with lots of sun, such as Africa or Asia.

But solar energy doesn’t only make sense in places where you have plenty of light. Canadian communities with as little as five hours of sun a day could soon leapfrog from diesel dependence to a clean energy economy.

Kuujjuaq, the largest Inuit community of the Nunavik territory, is leading the way with a project that saved more than 400 liters (105.67 gallons) of diesel between September and October, providing an equivalent amount of electricity (1,100 kwh) from solar panels.

With an investment of $560,000, the solar panels will not only generate energy, but also data and knowledge to plan big in the future. “Our pilot involves studying solar technology for a full 12 months period” Andy Moorhouse of Makivik Corporation, an organization that represents Inuit in Nunavik and manages the project, told Futurism.

“By the end of September 2018, we’ll be able to have full data on how these technologies did throughout the year, especially during dark times such as now,” he said. “It’s a learning scope for us, we want to see how well the technology handles our harshest climate, and try to understand if anything better could be designed specifically for the Arctic climate.”

“It absolutely makes sense to invest in renewable and hybrid energy systems in the Arctic,” Victoria Herrmann, director of the Washington-based Arctic Institute, told Futurism. She explained that on average, Arctic residents pay twice as much as their southern counterparts for heating, electricity, and transportation fuel. “For those living in the Arctic, petroleum fuel isn’t about global commodity markets: it’s about survival. Solar, wind, and other renewable energy sources are not just possible there, they’re profitable.”

While Canadian investors and governments are still dipping their toes into clean energy, states such as Alaska already boast success stories “that have proven [renewables] to be economically viable and a tremendous boost for remote communities’ energy sovereignty and economic vitality,” Herrmann said.

Projects like the solar panel pilot in Kuujjuaq and the large-scale installation planned for Old Crow, she said, prove that renewables can work for many of the over 170 remote Indigenous communities in Canada that rely on expensive and dirty diesel.

This year, Canada has allocated $400 million of its federal budget to the establishment of a 11-year Arctic Energy Fund. This, Herrmann said, “can do for the Canadian North what the Alaska Renewable Energy Fund has done for their neighbor.”

For now, the people of Kuujjuaq are waiting to see what’s in this project that may improve their lives in the long term. Moorhouse said that future plans will depend “on the results of this tests, and also we need to understand each community’s needs, including consumption patterns at different times of the year.” If the solar experiment proves viable, like early results suggest, the infrastructure could be scaled up to power schools or clinics, and eventually entire villages.

100% Renewable Energy Worldwide Isn’t Just Possible—It’s Also More Cost-Effective

Transitioning the world to 100 percent renewable electricity isn’t just some environmentalist pipe dream—it’s “feasible at every hour throughout the year” and is more cost-effective than the current system, which largely relies on fossil fuels and nuclear energy, a new study claims.

The research, compiled by Finland’s Lappeenranta University of Technology (LUT) and the Berlin-based nonprofit Energy Watch Group (EWG), was presented Wednesday at the Global Renewable Energy Solutions Showcase, a stand-alone event coinciding with the COP 23 climate talks in Bonn, Germany.

The authors said that the existing renewable energy potential and technologies coupled with storage can generate enough energy to meet the global electricity demand by 2050.

The researchers estimated that the switch will bring the total levelized cost of electricity on a global average down to €52 ($61) per megawatt-hour (including curtailment, storage and some grid costs) compared to €70 (82) megawatt-hour in 2015.

“A full decarbonization of the electricity system by 2050 is possible for lower system cost than today based on available technology,” said Christian Breyer, the lead author of the study.

“Energy transition is no longer a question of technical feasibility or economic viability, but of political will,” added Breyer, who is also a professor of Solar Economy at LUT and serves as chairman of EWG’s Scientific Board.

According to the study, solar power and battery storage are critical parts of the transition. Falling prices will also lead to widespread adoption of the technologies. The researchers predict that the globe’s electricity mix by 2050 will consist of solar photovoltaics (69 percent), wind energy (18 percent), hydropower (8 percent) and bioenergy (2 percent).

By following this path, greenhouse gas emissions in the electricity sector will come down to zero and drastically reduce total losses in power generation, the study found. Not only that, the renewable energy transition would create 36 million jobs by 2050, 17 million more than today.

“There is no reason to invest one more dollar in fossil or nuclear power production,” EWG president Hans-Josef Fell said. “Renewable energy provides cost-effective power supply. All plans for a further expansion of coal, nuclear, gas and oil have to be ceased. More investments need to be channeled in renewable energies and the necessary infrastructure for storage and grids. Everything else will lead to unnecessary costs and increasing global warming.”

This is the not the first time researchers have suggested that the planet’s road to 100 percent renewables is possible. Earlier this year, Stanford University professor Mark Jacobson and 26 co-authors published a study and created clean energy roadmaps for 139 individual countries. The chosen countries emit more than 99 percent of all carbon dioxide worldwide.
