Walmart has unveiled plans to further expand its use of solar panels, wind farms and electric vehicle charge points as it reported progress in slashing greenhouse gas emissions across its global supply chain last year.

The US retailer yesterday revealed it has worked with hundreds of global suppliers to achieve an overall cut in emissions of 20 million metric tonne during the first year of its Project Gigaton initiative.

Launched last April, the programme is aimed at cutting Walmart’s global supply chain greenhouse gases by one billion metric tonnes – or one gigaton – by 2030, and was recently been expanded to include suppliers in the UK and China.

It means there are now more than 400 suppliers with operations in more than 30 countries involved in Project Gigaton, through which companies supplying Walmart commit to emissions reductions across six areas: energy, agriculture, waste, packaging, deforestation and product use.

Kathleen McLaughlin, senior vice president and chief sustainability officer for Walmart, announced the latest Project Gigaton results at the firm’s annual sustainability summit yesterday, at which she also unveiled plans to expand Walmart’s use of solar, wind and EV charge points.

“In its first year, Project Gigaton has helped to inspire action that has led to the avoidance of millions of metric tons of greenhouse gas emissions and has expanded into an international campaign that includes the participation of several hundred suppliers,” she said. “The early success of Project Gigaton parallels ongoing progress in our operational efforts that seek to double our US renewable energy use and expand our customer electric vehicle charging hubs to retail outlets across more than 30 states.”

Walmart said it plans to more than double its EV charging station sites with the addition of several hundred charging stalls across its operations in 34 US states, bringing the retail giant’s total number of charging units to more than 1,000.

Several of the new charging stations will also feature super-fast chargers, it said, allowing drivers to charge up their EVs in between 10 and 30 minutes.

The retailer said it also plans to more than double the amount of renewable energy it uses in the US, focusing on expanding its on-site solar energy installations as well as purchasing more renewable power from wind farms through Power Purchase Agreements (PPAs).

It forms part of Walmart’s aim to supply its global operations with 50 per cent renewable energy by 2025. In the US, the retailer currently sources around 28 per cent of its power from renewables.

India Had Coal-Free Power Capacity Addition During 8 Months In 2017

India probably witnessed the greenest stretch of its power sector last year in terms of new capacity added. No thermal power capacity was added in 8 of the 12 months last year in India.

India managed to add coal-based power capacity in only 4 of the 12 months last calendar year. In six months, India actually retired coal-based power capacity, leading to a net reduction in installed coal-based capacity during those months. Overall, India added 7,115 megawatts of coal-based power capacity and retired 3,111 megawatts of capacity in 2017 — a net capacity addition of 4,004 megawatts during the entire year.

Only in three months did the coal-based power industry manage to beat capacity additions in the renewable energy industry. The largest monthly volume in the coal industry was seen in April 2017 with 3,115 megawatts capacity addition. The renewable energy industry saw addition of 7,242 megawatts in the same month.

Total capacity added in the renewable energy sector in 2017 was 12,829 megawatts, more than three times the net capacity addition in the coal sector. This is in stark contrast to the trends seen over the last few years.

In 2016, the coal-based power sector in India witnessed a net capacity addition of 15,950 megawatts — a gross capacity addition of 16,740 megawatts and 790 megawatts of retired capacity. Renewable energy industry witnessed the addition of 12,602 megawatts in 2016.

In 2016, the coal-based installed capacity in India had grown by 9.2% while in 2017 the capacity registered a meager growth of 2.1%. Renewable energy, on the other hand, grew by 33.7% in 2016 and 25.6% in 2017.

Renewable energy capacity additions have been driven largely by the solar power sector. While the capacity added in the solar and wind energy sector was evenly matched in 2016, the balance tipped overwhelming in favor of the solar sector in 2017.

US Wind Energy Now Supplies More Than 30% In Four States

Wind energy is one of the fastest growing forms of electricity generation in the United States, with the largest share renewable electricity generating capacity in the country, and according to new information from the American Wind Energy Association, wind energy now supplies more than 30% of the electricity in four states — Iowa, Kansas, Oklahoma, and South Dakota.

Launched in New Mexico this week — one of the rising stars of the US wind energy sector, adding wind power capacity at a faster rate in 2017 than any other state — the American Wind Energy Association (AWEA) published its U.S. Wind Industry Annual Market Report 2017 report which highlighted the role wind energy is playing in the country’s rapid expansion towards low-carbon electricity generation.

According to this latest report, wind power generated 6.3% of US electricity in 2017. However, wind’s impact can be better seen in its role in states like Iowa, Kansas, Oklahoma, and South Dakota, where it is generating over 30% of capacity. Looking further abroad, the report shows that more than 14 states are generating over 10% of electricity from wind. Overall, operating wind power capacity grew by 9% in 2017, with the installation of 7,017 megawatts (MW) worth of new capacity, bringing the country’s cumulative capacity up to 88,973 MW, or around 54,000 wind turbines operating in 41 states (as well as Guam and Puerto Rico).

“American wind power reached new heights for energy generated and U.S. jobs in 2017. And don’t be surprised when the industry continues to break records,” said Tom Kiernan, CEO of AWEA. “Wind is competitively priced, reliable, and clean – a winning combination that’s creating economic growth in all 50 states.”

New Mexico was highlighted by the AWEA as a standout, given that it is adding wind power capacity at a faster rate than any other state in the country. In 2017, New Mexico installed 570 MW — a 51% increase — and supplied over 13% of the state’s electricity generation.

“You can see the future of American energy here in New Mexico, where our industry grew at a faster rate than any other state last year,” said Kiernan. “It’s a place where wind farms and transmission lines are rapidly becoming staples of the economy, creating new jobs and bringing a wave of private investment to rural communities.”

“I’m proud that New Mexico’s wind power capacity grew at a faster rate than any other state and generated an unprecedented level of private sector investment and job growth,” added Martin Heinrich, the junior United States Senator from New Mexico. “With our robust wind and solar resources, New Mexico is at the epicenter of the rapidly growing clean energy economy. As consumers and major companies demand cheaper and cleaner power sources, our state stands to benefit and become an even bigger leader in this booming energy sector–especially in rural communities. We should be doing everything we can to meet our state’s full potential as a wind energy powerhouse, from building new transmission infrastructure to investing in job training programs. I will keep fighting for policies that move New Mexico’s energy economy forward.”

Meanwhile, the US wind energy industry is employing a record 105,500 people across the country, with wind projects or wind-related factories located in all 50 states (plus, again, Guam and Puerto Rico). The country now boasts over 500 wind-related factories which support over 23,000 factory jobs.

SunPower To Acquire SolarWorld Americas

Photo-illustration: Pixabay
Photo-illustration: Pixabay

In a move being billed as a “new chapter in American solar panel manufacturing” SunPower, one of the world’s leading solar manufacturers, has announced that it will acquire 100% of SolarWorld Americas, one of the two companies who filed a Section 201 trade case that led to the imposition of 30% tariffs on all imported solar cells and modules into the United States.

SolarWorld Americas, and its parent company SolarWorld have suffered from financial difficulties for years now, with the latter repeatedly filing for insolvency in its home country of Germany and the former seeking potential buyers to extricate it from the financial mess that it had created for itself and which had left it to side with Suniva in seeking government protection in the form of the Section 201 trade case, and which led to the imposition of a 30% tariff (for more, read here).

Announced on Wednesday, SunPower seems to have jumped into the fray in a move that might serve to reshape solar manufacturing in the United States, boasting as it would the return of SunPower to US manufacturing.

SunPower published a press release early on Wednesday morning, before trading opened, announcing that it had agreed to acquire 100% of the Hillsboro, Oregon-based SolarWorld Americas in a deal that failed to reveal its purchase price. According to SunPower, “SolarWorld Americas is the leading American manufacturer of solar panels” and its acquisition will seek “to revitalize the US high-technology manufacturing sector” by injecting “fresh capital into the SolarWorld Americas facility and implement leading-edge, high-efficiency P-Series solar panel manufacturing technology.” If the acquisition is approved — which will require approval from officials in both Germany and the United States — it will see SunPower become the largest US solar panel manufacturer.

Before approval is granted, however, and as of the time of writing, SunPower’s shares have already started to skyrocket in the first few minutes of trading on the New York Stock Exchange.

“We are thrilled to announce this agreement to acquire SolarWorld Americas, one of the most respected manufacturers of high-quality solar panels for more than 40 years,” said Tom Werner, SunPower CEO and chairman of the board. “The time is right for SunPower to invest in U.S. manufacturing, and SolarWorld Americas provides a great platform for us to implement our advanced P-Series solar panel manufacturing technology right here in our home market. P-Series technology was invented and perfected in Silicon Valley, and will now be built in SolarWorld Americas’ factory, helping to reshape solar manufacturing in America.”

SunPower will seek to ramp up SolarWorld Americas operations in an effort to “capitalize on strong US market demand” which, in short, stems from the continued growth of the solar industry but is also being driven by the need for locally-made solar cells and modules in the wake of the 30% tariff. SunPower — who design, manufacture, and deliver solar products — will invest in factory improvements and increased working capital, while also retrofitting a portion of SolarWorld Americas’ facility to be able to produce P-Series solar panels.

“SunPower is the solar industry technology leader,” added Jürgen Stein, CEO of SolarWorld Americas. “We are delighted that SunPower has agreed to inject fresh capital and their industry leading P-Series technology into SolarWorld Americas operations here in Hillsboro. Our hundreds of long-time employees are excited to be part of this next chapter in SolarWorld Americas’ long history. We are thrilled about this acquisition as it means quite simply, that our company can look forward to redoubled strength as it continues to innovate and expand into the future. This outcome is ideal for SolarWorld Americas and its employees.”

As companies based in the United States and around the world scramble to understand how the imposition of a 30% tariff on imported solar cells and modules will impact their businesses, many companies are re-thinking whether or not to invest in US manufacturing capacity. For SunPower, this acquisition of SolarWorld Americas may shortcut any number of issues they could otherwise have faced.

Siemens Gamesa Renewable Energy announced on Monday that it had been awarded the contract to supply wind turbines for four separate wind farms in Spain by developer Gas Natural Fenosa Renovables, for a total of 166 megawatts (MW).

The four wind farms in question are being developed by Gas Natural Fenosa Renovables, which was awarded the 166 MW capacity in Spain’s renewable energy auction held in May of 2017 that awarded 3 gigawatts (GW) worth, mainly to wind energy. The obvious preference for wind immediately caused the Spanish solar association (Unión Española Fotovoltaica) to cry foul. However, the reality of the situation — at least so far as I was able to tell at the time — was that wind energy was better placed to offer lower bids.

The company was actually awarded a total of 667 MW worth of wind power in the Spanish renewable energy auction, requiring €700 million in investments. This adds to a total installed capacity of 979 MW in Spain and another 234 MW spread across Australia, Mexico, and Brazil.

“The result from the auction highlights the value of the portfolio of renewable projects by the energy group, on which it has been working hard for the last few years and which has led to the creation of a truly competitive and streamlined portfolio of projects,” explained Rafael Villaseca, Gas Natural Fenosa Renovables’ CEO, at the time.

Fast-forward nearly a year and Gas Natural Fenosa Renovables has awarded the contract to supply the wind turbines for its four wind farms to Siemens Gamesa, one of, if not the leading wind turbine manufacturer in the world. Siemens Gamesa will provide 48 of its SG 3.4-132 wind turbines — one of its most popular products — and will also commission, operate, and maintain the turbines for three years, all of which are due to be completed mid-2019.

Beyond offering one of the world’s leading wind energy brands and a popular product, Siemens Gamesa also offers locally-produced turbines, with the turbine blades to be manufactured at the company’s Aoiz factory in Navarre, Spain and in nearby Tangiers, Morocco, and the nacelles will be manufactured at its Ágreda facility in Soria, Spain.

Activists Call on Red Sox to Go 100 Percent Renewable

On April 10, Massachusetts environmental groups launched a campaign asking the state’s beloved Red Sox baseball team to “go green,” an Environment Massachusetts press release reported.

In their joint “Sox Go Green” campaign, Environment Massachusetts and MASSPIRG Students are specifically calling on the team to source 100 percent of the power it uses for Fenway Park, its Florida spring training facility and all other team operations from renewable energy.

The campaign is not at all antagonistic to the team, but rather urges the Red Sox to use their name recognition to inspire other Massachusetts institutions to take environmental action.

“As a lifelong Sox fan, I know how important this team is in the eyes of everyone who lives in Massachusetts,” MASSPIRG chapter chair and UMass Boston student Morganne McGuirk said in the press release. “If the Red Sox go 100 percent renewable, other businesses and institutions will undoubtedly follow their lead.”

The activists want the team to follow a two-step schedule. In five years, they want them to get 100 percent of their electricity from New England solar and wind farms. In 10 years, they want them to meet all their transportation and heating needs from renewables as well.

Activists point out that if the Red Sox head their suggestion, they will be joining seven Massachusetts cities and towns and major state institutions like Harvard and Boston Universities, as well as 120 major companies including Google.

If the Red Sox agree, it would not be out of character for a team with a history of taking environmental actions.

They were the first Major League Baseball team to install solar thermal panels in 2008, which were used to heat water in Fenway Park. In spring of 2015, the they planted Fenway Farms, a rooftop garden over the third-base side of the park. Produce from the garden is used to prepare food sold at the stadium.

But the Red Sox are not alone among professional sports teams in taking action on environmental issues.

In March, the National Hockey League (NHL) announced plans to increase its environmental commitments over concerns that climate change would threaten the frozen ponds on which many of its players first learned to skate. The NHL said it would focus on reducing carbon emissions, supporting energy efficiency, and reducing waste and water use.

In the world of Football, the Philadelphia Eagles have 2,500 solar panels installed at their stadium.

The Red Sox main rivals, the New York Yankees, have also taken environmental action. Since the team’s new stadium opened in 2009, the team has used renewable energy certificates, which represent one megawatt-hour of renewable energy generated and delivered to the grid, for 100 percent of the stadium’s purchased energy.

“If I know anything about Boston, it’s that we don’t like to come in second to New York,” Environment Massachusetts State Director Ben Hellerstein said in the release. “The Red Sox should set their sights on winning the race to 100 percent renewable energy.”

India Added More Solar & Wind In 2017 Than Coal-Based Capacity

Photo - ilustration: Pixabay
Photo-illustration: Pixabay

Perhaps for the first time ever, India added more renewable energy capacity in a calendar year than coal-based capacity. One of the fastest growing renewable energy markets achieved this feat last year.

According to government data, India added 12.8 gigawatts of renewable energy capacity against just 4 gigawatts of net coal-based power capacity added in 2017. Renewable energy dominated the new capacity added in India with a massive share of 66%, up from 42% in 2016. Coal-based power capacity had a share of 21% in the new net capacity added, down from 54% in 2016.

Interestingly, the total power capacity added in India in 2017 was also down from 30 gigawatts in 2016 to 19 gigawatts in 2017. The sharp decline is also due to the 3.1 gigawatts of coal-based capacity retired last year, also a record.

Net coal-based capacity declined from 16 gigawatts in 2016 to just 4 gigawatts in 2017. Wind energy capacity declined marginally in 2017, from 4.3 gigawatts to 4.1 gigawatts. The solar power sector witnessed another record year with new capacity added increasing from 4.7 gigawatts to 8 gigawatts. A marginal fall wind capacity added in 2017 also meant virtually no growth in new renewable energy capacity added in 2017 compared to 2016.

More net capacity in the renewable energy sector was added in three of the four quarters last year than in the coal-based power sector. Since Q3 2015, India has seen more renewable energy capacity added in six of the 10 quarters.

Winds have been blowing in favor of India’s renewable energy sector over the last few months and quarters due to regular auctions in the solar and wind energy sectors. While the wind energy sector did see a slowdown due to policy changes, it is likely to be back on track of accelerated growth in the coming months as nearly 7.5 gigawatts of auctioned capacity (by early April 2018) comes online.

Similarly, large and regular solar power auctions have been planned at the central as well as state level across the country. These would also add to the huge pipeline of projects already auctioned and under construction.

Finland’s Fortum Wins Tender To Increase Country’s Solar Energy Capacity By 30%

The Finland-based firm Fortum has won a tender to build out the country’s total solar energy capacity by around 30%, it has revealed.

Given that Fortum is majority-owned by Finland itself, the fact that it won the tender isn’t too surprising itself, but it is interesting how substantial the tender is. The plan is reportedly to install solar photovoltaic (PV) systems on around 40 commercial buildings throughout the country.

While this will altogether only amount to around 10 megawatts (MW) worth of nameplate capacity, the buildout will actually represent the largest solar energy project to date among Finland, Sweden, and Norway, reportedly.

A statement on the matter released by the company noted that “installation work will start in spring 2018 and will be completed during autumn 2018.”

Notably, the exact terms and value of the deal have not been publicly disclosed.

Reuters provides some context on the matter: “The total solar power production capacity in Finland neared 35 MW by the end of 2017 and adding the new installations will increase the country’s output by about 30%…Fortum, the Nordic region’s largest utility in terms of customer base, has so far been active in the solar power industry mostly in India, where it has implemented projects with a total output of 185 MW.”

Presumably all of the new solar energy generation capacity will be installed in the the southern part of the country where solar insolation levels aren’t too bad. Even that being the case, such installations will still provide most of their generation potential during a period of just a half year or so, clustered around the summer solstice.

India A Step Closer To First Offshore Wind Energy Auction

Photo: Pixabay
Photo-illustration: Pixabay

Nearly eight years after we first covered news about India taking initial steps to set up offshore wind energy projects, the first government document seen as a precursor to a final auction has been released.

The Ministry of New and Renewable Energy recently issued an expression of interest document on its website. The Ministry wants to gauge market interest to set up 1 gigawatt of offshore wind energy capacity off the coast of Gujarat, western India.

Back in November 2010, we covered a news story stating that the Ministry is planning to conduct a survey to establish the generation potential for offshore wind energy. The survey was supposed to take two to three years to complete. There is no word on whether this survey has indeed been completed or not.

In 2015, the Ministry approved an offshore wind energy policy that outlined the various approvals project developers would require to set up the projects, the various agencies that would be involved in the approvals, and so on.

Late last year, the Ministry announced that it plans to hold auctions for 5 gigawatts of offshore wind energy capacity in 2018-19. Minster for New and Renewable Energy RK Singh stated that a feasibility study ongoing at one of the proposed sites is in progress, while a similar survey would begin at two more sites soon. Apart from Gujarat, offshore wind energy projects are likely to come up in Tamil Nadu as well.

As of February 28th, 2018, India had an installed wind energy capacity of 32.9 gigawatts. The government has set a target to increase this figure to 60 gigawatts by March 2022. The government is expected to auction 10 gigawatts of wind energy capacity each in 2018-19 and 2019-20 to this effect.

Since India introduced competitive auctions in the wind energy sector last year, nearly 7.5 gigawatts of capacity has been allocated to project developers. Minimum tariff bids in these auctions have collapsed by nearly 30% in a matter of just 12 months. Offshore wind energy auctions are expected to be highly competitive as well, even though the capital cost of at least the initial projects is expected to be high.

Claire Perry to Instruct Committee on Climate Change to Scope Net Zero Goal

UK Climate Minister says government will ask climate watchdog to consider how UK could meet 1.5C Paris target

Later this year the UK government will formally ask its official climate experts, the Committee on Climate Change (CCC), to explore the potential for the UK to tighten its emission reduction targets to bring them in line with international goals, Energy and Climate Minister Claire Perry announced today.

Speaking during the Commonwealth Heads of Government Meeting (CHOGM) taking place in London this week, Perry said she would instruct the CCC to report on the implications of the Paris Agreement’s target to limit a rise in global average temperature to “well below” 2C and aim for 1.5C.

“After the IPCC’s report later this year, we will be seeking the advice of the UK’s independent advisors, the Committee on Climate Change, on the implications of the Paris Agreement for the UK’s long-term emissions reduction targets,” Perry said.

Under the 2008 Climate Change Act the UK already has a target to cut greenhouse gas emissions by 80 per cent by 2050, against 1990 levels, which is technically consistent with Paris goals to limit warming to below 2C.

But there have been growing calls for the government to boost its national targets in light of the Paris Agreement’s target for reducing annual emissions to ‘net zero’ during the second half of the century, which would require anthropogenic emissions to be balanced by the removal of greenhouse gases from the atmosphere.

Campaign group Plan B is currently pursuing a legal challenge against the government in a bid to get the law strengthened, while research from the LSE’s Grantham Research Institute last month also backed a net zero goal.

In March 2016 former Energy Minister Andrea Leadsom promised the UK would enshrine a net-zero emissions goal into UK law, but following the Brexit vote and last year’s election plans stalled.

The Intergovernmental Panel on Climate Change – the IPCC – is due to release a report on the global implications of the 1.5C target in September. Perry said she would instruct the CCC to look at how the UK would meet such a goal after that report is released. The CCC will not only evaluate the UK’s current target in light of the 2015 Paris Agreement, but also latest science and technology, both of which have moved on fast in the 10 years since the Climate Change Act was first agreed.

If it does opt for a tougher goal, the UK government will have to act quickly to give the country the best chance of achieving faster decarbonisation. According to the LSE researchers, a fresh target would need to be in place by 2020 to coincide with the submission of revised ‘nationally determined contributions’ to the Paris Agreement and the CCC’s advice on the sixth carbon budget.

The UK is the first G7 country to formally promise to explore a net zero goal, and polling research suggests the move has strong public support. Conservative environmental think tank Bright Blue this week released analysis of polling from Opinium suggesting that 64 per cent of UK adults agree the UK should aim to cut its emissions to zero over the next few decades.

The survey, which questioned more than 4,000 adults, found that 51 per cent of people are more concerned about climate change today than a decade ago, climbing to 57 per cent among the under 40s.

“A net zero target is supported by a clear majority of the public, including Conservative voters, while concern about climate change is particularly high among younger voters,” Bright Blue head of research Sam Hall said. “By adopting a net zero target, the government is therefore seizing a great opportunity to appeal to key younger voters without trading off existing voters.”

Former climate diplomat and CEO of the European Climate Foundation Laurence Tubiana, today urged other nations to follow the UK’s lead.

“10 years after the UK pioneered its world-first Climate Change Act, today’s announcement shows that once again it is the British government looking to lead the world on climate change,” she said. “For a safe climate we need all governments to aim for cutting pollution to net zero levels by 2050. This decision to review Britain’s long-term climate target sends a strong message to the EU and other big economies that London is committed to the Paris Agreement, and now it’s time they too considered what more they can do.”

Reaction among other campaigners and climate experts was also almost universally positive. Ed Matthew, associate director at environmental think tank E3G, said a net zero goal would “cement the UK as the global leader in the battle against climate change”.

Former environment secretary and former leader of the Conservative Party Lord Michael Howard also welcomed the news. “The Climate Change Act has proven its worth, but as science and diplomacy move on, it should of course be kept under review – and the tougher international targets agreed at the Paris summit make it likely that the UK’s own target will need to be strengthened,” he said.

More Good News About Coal-Killing Perovskite Solar Cells

Foto-ilustracija: Pixabay
Photo-illustration: Pixabay

US coal and nuclear energy stakeholders are still holding out hope for their aging power plants, but the window for relief is closing fast. They face stiff competition from low-cost natural gas, and renewables are flexing their muscles, too. This is all happening before perovskite solar cells hit the market at scale. Why does this matter? New perovskite technology could drive solar costs down past conventional silicon solar cells, pushing both nuclear and fossil energy farther out of the picture.

For those of you new to the topic, perovskite refers to a class of lab-grown, crystalline materials that mimic the structure of the naturally occurring mineral perovskite.

Synthetic perovskites have caused quite a stir among photovoltaic researchers in recent years. They are relatively cheap and easy to grow in the lab, and they can be used in a thin-film format that provides the additional benefits of high volume, low-cost solar cell manufacturing.

In a perfect world, perovskites would offer a low-cost alternative to conventional silicon solar cells. Unfortunately for solar energy fans, the world is not a perfect place for perovskites because they degrade quickly when exposed to humidity.

On the bright side, there is a solution. Someone just has to find it.

The EU consortium Solliance is one of many research organizations working the problem. Last November it announced a world record of 13.5% for its thin film perovskite solar cell, and just last week it updated its perovskite PV progress. The latest iteration of the cell hit the 14.5% mark.

Last week’s announcement is also significant because Solliance demonstrated that the new cell can be interconnected with others to make a larger module without a significant loss of efficiency.

The trick is to make sure that the active material covers as much of the module as possible. Solliance shrank the non-active, interconnection areas down to a fraction. It achieved 95.3% coverage for the active areas and ended up with an efficiency of 13.5% for the module overall.

Then there’s that thing about low-cost manufacturing:

…Apart from the electrodes currently used, all layers can be processed in ambient environment and at temperatures below 120⁰C, making expensive equipment obsolete. The deposition and interconnection technologies are industrially available for both Sheet-to-Sheet and Roll-to-Roll manufacturing.

As for when you can get your hands on that low-cost thin film solar cell, that’s a good question. It doesn’t look like that will take forever, though. Panasonic is a partner in the consortium along with the “disruptive” renewable energy company Greatcell Solar Limited and the Russia-based solar business incubator Solartek.

Speaking of progress, one of the world’s biggest cheerleaders for perovskite solar cells is the National Renewable Energy Laboratory, and it has just come out with an article that outlines just how quickly things are developing in the field.

Perovskites were unstable and there were all kinds of problems—but you could clearly see in all the measurements that these were high-quality semiconductors. We saw where efficiency records were broken day after day after day. We realized this is not something we should be ignoring.

The article also makes a good case for the advantages of perovskites over silicon:

…The silicon technology requires a high-temperature manufacturing process, whereas the perovskite process is simpler: chemicals are applied to a substrate, either by deposition or roll-to-roll printing. When dry, the residue leaves crystals that serve as excellent semiconductors. This means perovskite panels are more flexible than rigid silicon panels…

At this point, NREL is confident that perovskites will break into the market. Here’s a take from NREL staff scientist David Moore:

I don’t see anything that stands in the way of commercialization of perovskite. There are a couple of challenges left. We need to make sure they’re going to last 30 years. But the strides we’re making in those areas are just as rapid as the progress we made with efficiency in the first five years. Just based on the progression of both of those things, there’s every reason to believe that we’ll continue on that path to solve those problems…

Less Meat and More Green Power: Scientists Cook Up 1.5 Degrees Trajectory with Minimal Reliance on Negative Emissions

Scientists at Utrecht University in the Netherlands have modelled a way to hit tough global climate targets without resorting to the extensive use of negative emissions technology such as bioenergy with carbon capture and storage (BECCS).

Most 1.5 degree climate scenarios – a temperature limit that would save low-lying islands from rising sea levels and avert the worst economic and ecological impacts of climate change – rely heavily on negative emissions technology to make the numbers add up.

But such technology is still relatively unproven and commercially challenging, while planting more foreststo act as carbon sinks takes time and eats into the available land to grow food.

Researchers at Utrecht University claimed to have found a way around this challenge last week, with the release of a new paper explaining how the 1.5 degrees target can be reached with a radically scaled down use of negative emissions technology.

Using computer modelling, the scientists found that by using more renewable power and cutting down on agriculture emissions the world can hit 1.5 degrees with substantially less use of negative emissions technology.

Animal production, for example, is responsible for up to 14.5 per cent of global emissions, as well as demanding extensive land and water use and playing a role in deforestation. If humans limited intake of meat and dairy to a healthy amount the pressure to use negative emissions would ease substantially.

Detlef van Vuuren, project manager of the IMAGE project and professor at Utrecht University, acknowledged that such lifestyle shifts may be difficult to deliver. “It is clear that each path comes with its own challenges,” he admitted. “For example, a change in dietary habits entails a large-scale change in the global food system. In any case, each scenario shows a clear break with past trends.”

But the paper notes that such alternative scenarios offer many other global benefits in line with the Sustainable Development Goals, such as improving health and global food supply.

The paper also stressed that ongoing investment in negative emissions technology would be necessary in any scenario in order to meet the 1.5 degree target.

Majority of Americans Want Climate Education in Schools

In a rebuke to efforts by the Heartland Institute and at least 10 state legislatures, a large majority of Americans believe climate change should be taught in schools, the Yale Program on Climate Change Communication (YPCCC) reported Wednesday.

When the YPCCC asked Americans, “Should schools teach our children about the causes, consequences, and potential solutions to global warming?”, a national average of 78 percent either somewhat or strongly agreed that they should.

Moreover, a large majority shared that view in all of the 50 states and more than 3,000 counties surveyed, whether or not they favored Republicans or Democrats in elections.

The results suggest that efforts in at least 10 states to alter how climate change is addressed in state educational standards are out of step with voters.

For example, YPCCC holds up the case of Idaho, where state legislators argued that no section on human-caused climate change should be included in state science standards, but instead arguments for and against a human role should be presented. Scientists and educators successfully argued that such a move would damage the education and futures of students by presenting a scientific consensus on an urgent issue as up-for-debate. The final decision was in line with the majority of Idahoans views, since, according to YPCCC data, 76 percent of them support climate education.

The same is true for the residents of other states debating their science standards, including Texas, Oklahoma and Kentucky.

National Center for Science Education Deputy Director Glenn Branch told Business Insider in 2017 that, when it comes to determining state science standards, “the two topics that arouse the most discontent and controversy are climate change and evolution.”

But the YPCCC data suggests that that controversy is manufactured at the political level and not felt by most Americans.

One key controversy-monger, according to YPCCC, is the climate-denying think tank the Heartland Institute. In March 2017, the fossil-fuel-funded group sent out 25,000 copies of a book called Why Scientists Disagree About Global Warming to science teachers nationwide.

Despite that effort, majority opinion seems more in line with the Next Generation Science Standards (NGSS), a science-education template that Branch called “the gold standard.” The NGSS clearly link human activity to climate change and have been accepted by 19 states and Washington, DC, Business Insider reported.

However, more teacher education is needed to ensure U.S. school children are learning accurate climate science. YPCCC cited research published in Science that found that only 30 percent of middle school and 45 percent of high school science teachers understand the degree of scientific consensus on human-caused climate change. Worse, 30 percent of teachers who teach climate change tell their students it is due to natural causes.

Good News, Bad News For Renewable Energy In New Jersey

When Chris Christie, former governor of New Jersey, wasn’t closing traffic lanes leading to the George Washington Bridge to punish political opponents, he was putting up barriers to renewable energy. Now that he has been consigned to the dustbin of history, his successor, Philip Murphy, is pushing a plan that will help New Jersey realize 50% of its electrical energy from renewables by 2030. That target brings the state in line with similar programs underway in California and New York.

New Jersey, like several other states and many individual cities, is determined to do its part to meet America’s commitments to the Paris climate change accords, despite headwinds from the Trump administration. “If you look at the United States commitments under Paris, these percentages would more than uphold New Jersey’s share of the burden,” Robert C. Orr, the primary science adviser to the UN secretary general, tells the New York Times. Orr is now the dean of the School of Public Policy at the University of Maryland.

“Obviously, New Jersey is a significant state, but it’s not a driver in the same sense that California is,” he says. “But by putting New Jersey in a group with California and New York and then Vermont and Maryland, you start to see, not getting all the way to Paris targets, but you start to see the trend line moving toward us meeting Paris.” Governor Murphy has also been supportive of an initiative to build offshore wind turbines along the New Jersey coast, something Christie openly opposed. The new initiative seeks to build 3,500 megawatts of offshore wind generation by 2030, enough to power 1.5 million homes.

The part of Murphy’s plan that will not please environmentalists is his embrace of nuclear energy. “I believe the biggest bridge we have to our clean energy future are the nukes and, not to mention, the thousands of jobs they support,” he says. New Jersey currently derives nearly half of its electricity from four nuclear power plants. One of those — the Oyster Creek facility — is scheduled to close soon, but Murphy’s plan will shovel $300 million a year to the remaining nukes to keep them going for a few more years. New Jersey rate payers will have the privilege of paying the subsidy.

Nonetheless, some environmental groups feel the need to temper their distaste for the program. “We don’t want to see the abrupt closure of nuclear plants, because if you close them tomorrow, we know that they’ll just be replaced by more fossil fuels,” says Dale Bryk, senior strategic director for the Natural Resources Defense Council. “You have to have an orderly transition plan that involves scaling up renewables first, so that when the nuclear plants close, they’re replaced with clean energy.”

Not everyone is so sanguine, however. “It’s going to put a chilling effect on spending more for renewable energy, because to build out renewable will cost much more,” says Jeff Tittel, director of the New Jersey Sierra Club. “This bill is about a nuclear subsidy, and that’s the primary purpose. And that’s the diversion to make you think you’re getting something that you’re not.”

New York and Illinois have granted similar subsidies to nuclear facilities but they contain a provision the New Jersey legislation does not. Every three years, the companies that operate nuclear reactors in those states will have to open their books to demonstrate they still need the subsidy. The New Jersey nuclear plants will be under no such obligation.

Green energy proponents will complain the subsidies should be used to install more renewable energy facilities and they have a valid point. In the long run, every available dollar should be put to work creating the clean energy grid of the future rather than propping up traditional generating facilities that are no longer economically viable. Still, Rome wasn’t built in a day. Some progress is better than none, especially at a time when federal policy favors a return to the age of steam.
