First Solar has been one of the biggest players in solar, but it has some challenges on the horizon.

ItÂ’s not insurmountable for a company that is projecting to make between $3.7 billion and $3.9 billion for 2011, but the solar market can change fast.

On a conference call with analysts following the release of its first quarter earnings, First Solar officials said the challenges arenÂ’t unique.

One big hurdle the company has to deal with is financing from the U.S. Department of EnergyÂ’s loan guarantee program. Funds from the program as going into a deal that would have First Solar selling its Agua Caliente power plant to NRG Energy Inc. NRG has been pegged to get $967 million from the DOE program, but the deal is still pending.

ItÂ’s similar to what happened with Abengoa Solar on its Solana Generating Station. The company received notice of the loan guarantee in July 2010 but didnÂ’t finalize the deal until December.

“The process on the DOE side has taken just a little longer than expected,” said Larry Polizzotto, the company’s vice president of investor relations. “That could end up getting done by the end of the second quarter, but it might go into the third quarter.”

First Solar has three other projects in the DOE pipeline, and all seem to be moving forward, Polizzotto said.

Other issues involved the uncertainty over feed-in tariff programs in Europe. Several European countries, including Spain and Germany, have either dropped the tariffs or are planning to do so. The tariffs are a fixed amount that solar energy providers receive from utilities to buy power.

The result has First Solar potentially accelerating its North American pipeline if the demand in Europe isnÂ’t there. The company added 50 megawatts to its plans for this year in North America, and that number could grow further.

Competitive challenges may lie in the future. SunPower Corp. announced that French oil giant Total SA was putting in an estimated $4.2 billion to take a majority stake in the silicon panel manufacturer based in San Jose. That could add muscle to SunPowerÂ’s efforts to bring its panels to a larger market.

That comes after a mid-April announcement that General Electric was getting back into the solar market and using the same type of thin-film panels First Solar has used to develop solar systems.

GE doesnÂ’t have the development pipeline First Solar does, but it does have capital, and it has been a lender for solar systems in the past.

Rob Gillette, CEO of First Solar, said he expects other large companies to jump into solar as it becomes more cost effective and prices continue to fall.

“I think there will be more and more large companies that will jump into the industry, and we need a lot of viable competitors to really drive the technology into the utility sector,” he said.

$1 billion per year is being spent to support climate change denial

Climate Change Consensus and Disinformation highlights the 97% peer-reviewed agreement on human-caused warming, IPCC warnings, and how fossil fuel lobbying, misinformation, and astroturf tactics echo tobacco denial to mislead media and voters.

 

Key Points

Explains the 97% scientific consensus and the disinformation that obscures IPCC findings and misleads the public.

✅ 97% peer-reviewed consensus on human-caused climate change

✅ Fossil fuel funding drives denial and media misinformation

✅ IPCC and major scientific bodies confirm severe impacts

 

Orson Johnson says there is no scientific consensus on climate change. He’s wrong. A 2015 study by Drexel University’s Robert Brulle found that nearly $1 billion per year is being spent to support climate change denial. Electric utilities, fossil fuel and transportation sectors outspent environmental and renewable energy sectors by more than 10-to-1, undermining efforts to achieve net-zero electricity emissions globally. It is virtually the same strategy that tobacco companies used to deny the dangers of tobacco smoke, spending hundreds of millions of dollars to delay recognition of harm from tobacco smoke for decades, and today Trump's oil policies can similarly influence Wall Street's energy strategy. These are the same debunked sources Johnson quotes in his commentary.

The authors of six independent peer-reviewed papers on the consensus for human-caused climate change examined “the available studies and conclude that the finding of 97% consensus in published climate research is robust and consistent with other surveys of climate scientists and peer-reviewed studies,” according to an abstract in Environmental Research Letters, and public support for action is strong, with most Americans willing to contribute financially to climate solutions. Of the 30,000 scientists (people with a bachelor’s degree or higher in science) Johnson cites, only 39 specialized in climate science.

A new study by the U.N. Intergovernmental Panel on Climate Change draws on momentum from the Katowice climate summit to warn that “The consequences for nature and humanity are sweeping and severe.”

California’s Office of Planning and Research says: “Every major scientific organization in the United States with relevant expertise has confirmed the IPCC’s conclusion, including the National Academy of Sciences, the American Meteorological Society, the American Geophysical Union, and the American Association for the Advancement of Science. The list of international scientific organizations affirming the worldwide consensus on climate change is even longer.”

Former President Obama argued that decarbonization is irreversible as the clean-energy transition accelerates.

This issue is a symptom of an even larger problem. Recently, Facebook announced it would continue to allow political ads that contain obvious lies. America’s corporate news media has been following the same policy for years. Printing stories and commentary with information that is clearly not true or where data has been cherry-picked to strongly imply a lie, such as claims that Ottawa is making electricity more expensive for Albertans, sets up a false equivalence fallacy in which two incompatible arguments appear to be logically equivalent when, in fact, they are not.

Conservatives focus exclusively on progressive income taxes to argue that rich people pay a disproportionate share of taxes while ignoring that they take a disproportionate share of income, and federal income taxes account for less than half of taxes collected, with almost all of the other taxes being heavily regressive. Critics of single-payer healthcare disregard that almost every other developed country on earth has been using single-payer for decades to provide better care with universal coverage at roughly half the cost. Other examples abound, including recent policy milestones like the historic U.S. climate deal that nevertheless become targets of misinformation. We live in a society where truth is no longer truth, reality is supplanted by alternative facts and where crippling polarization is driven by the inability to agree on basic facts.

The crisis in numbers: How COVID-19 has reshaped Saskatchewan

Saskatchewan COVID-19 economic impact: real-time data shows drops in electricity demand, oil well licensing, traffic and tickets, plus spikes in internet usage, government site visits, remote work, and alcohol wholesale volumes.

 

Key Points

COVID-19 reduced energy use, drilling and traffic, while pushing activity online; jobs, rents and sales show strain.

✅ Electricity demand down 6.7%; residential usage up

✅ Oil well license applications fell 15-fold in April

✅ Internet traffic up 16%-46%; wireless LTE up 34%

 

We’re only just beginning to grasp how COVID-19 has upended Saskatchewan’s economy, its government and all of our lives.

The numbers that usually make headlines — job losses, economic contraction, bankruptcies — are still well behind the pace of the virus and its toll.

But other numbers change more quickly. Saskatchewan people are using less power, and the power industry is adopting on-site staffing plans to ensure reliability as conditions evolve. We’re racking up fewer speeding tickets. And as new restrictions come, we’re clicking onto Saskatchewan.ca as much as 10,000 times per minute.

Here’s some data that provides a first glimpse into how much our province has changed in just six weeks.

Electricity use tends to rise and fall in tandem with the health of the economy, and the most recent data from SaskPower suggests businesses are powering down, while regional utilities such as Manitoba Hydro seek unpaid days off to trim costs.

Peak load requirements between March 15 and April 26 were 220 MW lower than during the same period in 2019, and elsewhere BC Hydro is posting COVID-19 updates at Site C as it manages project impacts. That’s a decrease of 6.7 per cent, with total load on April 29 at 2,551 MW. A megawatt is enough electricity to power about 1,000 homes.

Separate from pandemic impacts, an external investigation at Manitoba Hydro has drawn attention to workplace conduct issues.

But it’s not homes that are turning off the lights. SaskPower spokesman Joel Cherry said commercial and industrial usage is down, while residential demand is up, with household electricity bills rising as more people stay home.

The timing of power demand has also shifted, a pattern seen as residential electricity use rises during work-from-home routines. Peak load would usually come around 8 or 9 p.m. in April. Now it’s coming earlier, typically between 5 and 6 p.m.

Oil well applications fall 15-fold
Oil prices have cratered since late February, and producers in Saskatchewan have reacted by pulling back on drilling plans, while neighbouring Alberta provides transition support for coal workers amid broader energy shifts.

Applications for well licences fell from 242 in January to 203 in February (including nine potash and one helium operations), before dropping to 84 in March. April, the month benchmark oil prices went negative for one day, producers submitted just 15 applications.

That’s 15 times fewer than the 231 applications the Ministry of Energy and Resources received in April 2019.

Well licences are needed for drilling, operating, injecting, producing or exploring an oil and gas or potash well in the province.

There has been no clear trend in well abandonment, however. There were 176 applications for abandonment in March and 155 in April, roughly in line with figures from the year before.

SGI spokesman Tyler McMurchy believes the lower numbers might stem from a combination of lower traffic volumes during part of the month, possibly combined with a shift in police priorities. The March 2020 numbers are also well below January and February figures.

Indeed, the Ministry of Highways and infrastructure reported a 16 per cent decrease in average daily traffic last month compared to March 2019, through its traffic counts at 11 different spots on highways across the province.

In Regina, traffic counts at 16 locations dropped from a high of 2.1 million in the first week of March to a low of 1.3 million during the week of March 22. That’s a 44 per cent decrease.

Counts have gradually recovered to 1.6 million in the weeks since. The data was fairly consistent at all 16 spots, which are largely major intersections, though the city cautioned they may not be representative of Regina as a whole.

Tickets for cellphone use while driving also fell, dropping from 562 in February to 314 in March. McMurchy noted that distracted driving numbers in general have been falling since November as stiffer penalties were announced. Impaired driving tickets were up, by contrast, but still within a typical range.

Internet traffic shoots up 16 per cent, far more for rural high speed
You may be spending a lot more time on Netflix and Facebook in the age of social distancing, and SaskTel has noticed.

From late February to late April, SaskTel has seen “very significant increases in provincial data traffic.” DSL and fibre optic networks have handled a 16 per cent increase in traffic, while demand on the wireless LTE network is up 34 per cent.

Usage on the Fusion network up 46 per cent. That network serves rural areas that don’t have access to other high-speed options.

The specific reference dates for comparison were February 24 and April 27.

“We attribute these changes in data usage to the pandemic and not expected seasonal or yearly shifts in usage patterns,” said spokesman Greg Jacobs.

Saskatchewan.ca was attracting just 70 page views per minute on average in February. But page views jumped over 10,000 per minute at 2:38 p.m. on March 18, as Moe was still announcing the new measures.

That’s a 14,000 per cent increase.

For all of March, visitor sessions on the site clocked in at 3,905,061, almost four times the 944,904 recorded for February.

Bureaucracy has increasingly migrated to cyberspace, with 62 per cent of civil servants now working from home. Government Skype calls, both audio and video, have tripled from 12,000 sessions per day to 35,000.Telephone conference calls increased by a factor of 14 from the first week of February to the second full week of April, with 25 times more weekly call participants. 

The Ministry of Central Services reported a 17 per cent jump in emails received by government over the past two months, excluding the Ministry of Health.

But as civil servants spend more time on their computers, the government’s fleet is spending a lot less time on the road. The ministry has purchased 40 per cent fewer litres of fuel for its vehicles over the past four weeks, compared to the same time last year.

Alcohol wholesale volumes up 22 per cent, then fall back to normal
Retailers bought more alcohol from the Saskatchewan Liquor and Gaming Authority (SLGA) last month, just as the government began tightening pandemic restrictions.

Wholesale sales volumes were up 22 per cent over March 15 to 28, compared to the same period in 2019. SLGA spokesman David Morris said the additional demand “was likely the result of retailers stocking-up as restrictions related to COVID-19 took effect.”

But the jump didn’t last. Wholesale volumes were back to normal for the first two weeks of April. SLGA did notice a very slight uptick last week, however, with volumes out of its distribution centre up three per cent. The numbers do not include Brewer’s Distributors Ltd.

It’s unclear how much more alcohol consumers actually purchased, since province-wide retail numbers were not available.

There was no discernible trend in March for anti-anxiety medication, however. The number of prescriptions filled for benzodiazepines like Valium, Xanax and Ativan see-sawed over March, according to data provided by the College of Physicians and Surgeons, but its associate registrar does not believe the trends are statistically relevant.

One-fifth of tenants miss April rent
About 20 per cent of residential rent went totally unpaid in the first six days of April, according to the Saskatchewan Landlord Association (SLA).

The precise number is 19.7 per cent, but there’s some uncertainty due to the survey method, which is based on responses from 300 residential landlords with 14,000 units. An additional 12 per cent of tenants paid a portion of their rent, but not the full amount. The figures do not include social housing.

Cameron Choquette, the association’s executive officer, partly blames the province’s decision to suspend most landlord tenant board hearings for evictions, saying it “allows more people to take advantage of landlords by not paying their rent and not facing any consequences.”

The government has defended the suspension by saying it’s needed to ensure everyone has a safe place to self-isolate if needed during the pandemic.

March’s jobs numbers were bad, with almost 21,000 fewer Saskatchewan people employed compared to February.

April’s labour force survey is expected on Friday. But new April numbers released Wednesday show that two-thirds of the province’s businesses managed to avoid laying off staff almost entirely.

According to Statistics Canada, 66.2 per cent of businesses reported laying off between zero and one per cent of their employees due to COVID-19. That was better than any other province. Just 7.6 per cent laid off all of their employees, again the best number outside the territories. The survey period was April 3 to 24.

Some businesses are even hiring. Walmart, for instance, has hired 300 people in Saskatchewan since mid-March.

Trade and Export Development Minister Jeremy Harrison chalked the data up to a relatively more optimistic business outlook in Saskatchewan, combined with “very targeted” restrictions and a support program for small and medium businesses.

That support program, which provides $5,000 grants to qualifying businesses affected by government restrictions, has only been around for three weeks. But it’s already been bombarded with 6,317 applications.

The total value of those applications would be $24,178,000, according to Harrison. Of them, 3,586 have been approved with a value of $11,755,000.

Businesses are coming to Harrison’s ministry with thousands of questions. Since it opened in March, the Business Response Team has received 4,125 calls and 1,758 emails.

The kinds of questions have changed over the course of the pandemic. Many are now asking when they can open their doors, according to Harrison, as they wonder about “grey areas” in the Re-Open Saskatchewan plan.

TagEnergy Launches France’s Largest Battery Storage Platform

TagEnergy France Battery Storage Platform enables grid flexibility, stability, and resilience across France, storing wind and solar power, balancing supply and demand, reducing curtailment, and supporting carbon neutrality with fast-response, utility-scale capacity.

 

Key Points

A utility-scale BESS in France that stores renewable energy to stabilize the grid, boost flexibility, and cut emissions.

✅ Several hundred MW utility-scale capacity for peak shaving.

✅ Fast-response frequency regulation and voltage support.

✅ Reduces fossil peaker use and renewable curtailment.

 

In a significant leap toward enhancing France’s renewable energy infrastructure, TagEnergy has officially launched the country's largest battery storage platform. This cutting-edge project is set to revolutionize the way France manages its electricity grid by providing much-needed flexibility, stability, and resilience, particularly as the country ramps up its use of renewable energy sources and experiences negative prices in France during periods of oversupply,

The new battery storage platform, with a total capacity of several hundred megawatts, will play a crucial role in facilitating the country's transition to a greener, more sustainable energy future. It marks a significant step forward in addressing one of the most pressing challenges of renewable energy: how to store and dispatch power generated from intermittent sources such as wind and solar energy.

The Role of Battery Storage in Renewable Energy

Battery storage systems are key to unlocking the full potential of renewable energy sources. While wind and solar power are increasingly important in reducing reliance on fossil fuels, their intermittent nature—dependent on weather conditions and time of day—presents a challenge for grid operators. Without an efficient way to store surplus energy produced during peak generation periods, when negative electricity prices can emerge, the grid can become unstable, leading to waste or even blackouts.

This is where TagEnergy’s new platform comes into play. The state-of-the-art battery storage system will capture excess energy when production is high, and then release it back into the grid during periods of high demand, supporting peak demand strategies or when renewable generation dips. This capability will smooth out the fluctuations in renewable energy production and ensure a constant, reliable supply of power to consumers. By doing so, the platform will not only stabilize the grid but also increase the overall efficiency and utilization of renewable energy sources.

The Scale and Scope of the Platform

TagEnergy's battery storage platform is one of the largest in France, with a capacity capable of supporting a wide range of energy storage needs across the country. The platform’s size is designed to handle significant energy loads, making it a critical piece of infrastructure for grid stability. The project will primarily focus on large-scale energy storage, but it will also incorporate cutting-edge technologies to ensure fast response times and high efficiency in energy release.

France’s energy mix is undergoing a transformation as the country aims to achieve carbon neutrality by 2050. With ambitious plans to expand renewable energy production, particularly from offshore wind such as North Sea wind potential, solar, and hydropower, energy storage becomes essential for managing supply and demand. The new battery platform is poised to provide the necessary storage capabilities to keep up with this shift toward greener, more sustainable energy production.

Economic and Environmental Impact

The launch of the battery storage platform is a major boon for the French economy, creating jobs and attracting investment in the clean energy sector. The project is expected to generate hundreds of construction and operational jobs, providing a boost to local economies, particularly in the areas where the storage facilities are located.

From an environmental perspective, the platform’s ability to store and release renewable energy will greatly reduce the country’s reliance on fossil fuels, decreasing greenhouse gas emissions. The efficient storage of solar and wind energy will mean that more clean electricity can be used, with solar-plus-storage cheaper than conventional power in Germany underscoring cost competitiveness, even during times when these renewable sources are not producing at full capacity. This will help France meet its energy and climate goals, including reducing carbon emissions by 40% by 2030 and achieving carbon neutrality by 2050.

The development also aligns with broader European Union goals to increase the share of renewables in the energy mix. As EU nations work toward their collective climate commitments, energy storage projects like TagEnergy’s platform will be vital in helping the continent achieve a greener, more sustainable future.

A Step Toward Energy Independence

The new battery storage platform also has the potential to enhance France’s energy independence. By increasing the storage capacity for renewable energy, France will be able to rely less on imported fossil fuels and energy from neighboring countries, particularly during periods of high demand. Energy independence is a key strategic goal for many nations, as it reduces vulnerability to geopolitical tensions and fluctuating energy prices.

In addition to bolstering national security, the platform supports France’s energy transition by facilitating the deployment of more renewable energy. As storage capacity increases, grid operators will be able to integrate larger quantities of intermittent renewable energy without sacrificing reliability. This will enable France to meet its long-term energy goals while also supporting the EU’s ambitious climate targets.

Future of Battery Storage in France and Beyond

TagEnergy’s launch of France’s largest battery storage platform is a monumental achievement in the country’s energy transition. However, it is unlikely to be the last of its kind. The success of this project could pave the way for similar initiatives across France and the wider European market. As battery storage technology advances, and affordable solar batteries scale up, the capacity for storing and utilizing renewable energy will only grow, unlocking new possibilities for clean, affordable power.

Looking ahead, TagEnergy plans to expand its operations and further invest in renewable energy solutions. The French market, along with growing demand for storage solutions across Europe, presents significant opportunities for further development in the energy storage sector. With the continued integration of renewable energy into the grid, large-scale storage platforms will play an increasingly critical role in shaping a low-carbon future.

The launch of TagEnergy’s battery storage platform marks a pivotal moment for France’s renewable energy landscape. By providing critical storage capacity and ensuring the reliable delivery of clean electricity, the platform will help the country meet its ambitious climate and energy goals. As technology advances and the global transition to renewables accelerates, with over 30% of global electricity now coming from renewables, projects like this one will play an essential role in creating a sustainable, low-carbon energy future.

California proposes income-based fixed electricity charges

Income Graduated Fixed Charge aligns CPUC billing with utility fixed costs, lowers usage rates, supports electrification, and shifts California investor-owned utilities' electric bills by income, with CARE and Climate Credit offsets for low-income households.

 

Key Points

A CPUC proposal: an income-based monthly fixed fee with lower usage rates to align costs and aid low-income customers.

✅ Income-tiered fixed fees: $0-$42; CARE: $14-$22, by utility territory

✅ Usage rates drop 16%-22% to support electrification and cost-reflective billing

✅ Lowest-income save ~$10-$20; some higher earners pay ~$10+ more monthly

 

The Public Advocates Office (PAO) for the California Public Utilities Commission (CPUC) has proposed adding a monthly income-based fixed charge on electric utility bills based on income level.  

The rate change is designed to lower bills for the lowest-income residents while aligning billing more directly with utility costs. 

PAO’s recommendation for the Income Graduated Fixed Charge places fees between $22 and $42 per month in the three major investor-owned utilities’ territories, including an SDG&E minimum charge debate under way, for customers not enrolled in the California Alternative Rates for Energy (CARE) program. As seen below, CARE customers would be charged between $14 per month and $22 a month, depending on income level and territory.

For households earning $50,000 or less per year, the fixed charge would be $0, but only if the California Climate Credit is applied to offset the fixed cost.

Meanwhile, usage-based electricity rates are lowered in the PAO proposal, part of major changes to electric bills statewide. Average rates would be reduced between 16% to 22% for the three major investor-owned utilities.

The lowest-income bracket of Californians is expected to save roughly $10 to $20 a month under the proposal, while middle-income customers may see costs rise by about $20 a month, even as lawmakers seek to overturn income-based charges in Sacramento.

“We anticipate the vast majority of low-income customers ($50,000 or less per year) will have their monthly bills decrease by $10 or more, and a small proportion of the highest income earners ($100,000+ per year) will see their monthly bills rise by $10 or more,” said the PAO.

The charges are an effort to help suppress ever-increasing electricity generation and transmission rates, which are among the highest in the country, with soaring electricity prices reported across California. Rates are expected to rise sharply as wildfire mitigation efforts are implemented by the utilities found at fault for their origin.

“We are very concerned. However, we do not see the increases stopping at this point,” Linda Serizawa, deputy director for energy, PAO, told pv magazine. “We think the pace and scale of the [rate] increases is growing faster than we would have anticipated for several years now.”

Consumer advocates and regulators face calls for action on surging electricity bills across the state.

The proposed changes are also meant to more directly couple billing with the fixed charges that utilities incur, as California considers revamping electricity rates to clean the grid. For example, activities like power line maintenance, energy efficiency programs, and wildfire prevention are not expected to vary with usage, so these activities would be funded through a fixed charge.

Michael Campbell of the PAO’s customer programs team, and leader of the proposed program, likened paying for grid enhancements and other social programs with utility rate increases to “paying for food stamps by taxing food.” Instead, a fixed charge would cover these costs.

PAO said the move to lower rates for usage should help encourage electrification as California moves to replace heating and cooling, appliances, and gas combustion cars with electrified counterparts. In addition, lower rates mean the cost burden of running these devices is improved.

Cheap material converts heat to electricity

Polycrystalline Tin Selenide Thermoelectrics enable waste heat recovery with ZT 3.1, matching single crystals while cutting costs, powering greener car engines, industrial furnaces, and thermoelectric generators via p-type and emerging n-type designs.

 

Key Points

Low-cost tin selenide devices that turn waste heat into power, achieving ZT 3.1 and enabling p-type and n-type modules.

✅ Oxygen removal prevents heat-leaking tin oxide grain skins.

✅ Polycrystalline ingots match single-crystal ZT 3.1 at lower cost.

✅ N-type tin selenide in development to pair with p-type.

 

So-called thermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, providing what seems like a free lunch. But despite helping power the Mars rovers, the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermoelectrics that work just as well as the pricey kind. The work could pave the way for a new generation of greener car engines, industrial furnaces, and other energy-generating devices.

“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist at Beihang University who was not involved with the work. He notes there are still a few more steps to take before these materials can become high-performing thermoelectric generators. However, he says, “I think this will be used in the not too far future.”

Thermoelectrics are semiconductor devices placed on a hot surface, like a gas-powered car engine or on heat-generating electronics using thin-film converters to capture waste heat. That gives them a hot side and a cool side, away from the hot surface. They work by using the heat to push electrical charges from one to the other, a process of turning thermal energy into electricity that depends on the temperature gradient. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.

 Over the past 2 decades, researchers have produced thermoelectric materials with increasing ZTs, while related advances such as nighttime solar cells have broadened thermal-to-electric concepts. The record came in 2014 when Mercouri Kanatzidis, a materials scientist at Northwestern University, and his colleagues came up with a single crystal of tin selenide with a ZT of 3.1. Yet the material was difficult to make and too fragile to work with. “For practical applications, it’s a non-starter,” Kanatzidis says.

So, his team decided to make its thermoelectrics from readily available tin and selenium powders, an approach that, once processed, makes grains of polycrystalline tin selenide instead of the single crystals. The polycrystalline grains are cheap and can be heated and compressed into ingots that are 3 to 5 centimeters long, which can be made into devices. The polycrystalline ingots are also more robust, and Kanatzidis expected the boundaries between the individual grains to slow the passage of heat. But when his team tested the polycrystalline materials, the thermal conductivity shot up, dropping their ZT scores as low as 1.2.

In 2016, the Northwestern team discovered the source of the problem: an ultrathin skin of tin oxide was forming around individual grains of polycrystalline tin selenide before they were pressed into ingots. And that skin acted as an express lane for the heat to travel from grain to grain through the material. So, in their current study, Kanatzidis and his colleagues came up with a way to use heat to drive any oxygen away from the powdery precursors, leaving pristine polycrystalline tin selenide, whereas other devices can generate electricity from thin air using ambient moisture.

The result, which they report today in Nature Materials, was not only a thermal conductivity below that of single-crystal tin selenide but also a ZT of 3.1, a development that echoes nighttime renewable devices showing electricity from cold conditions. “This opens the door for new devices to be built from polycrystalline tin selenide pellets and their applications to be explored,” Kanatzidis says.

Getting through that door will still take some time. The polycrystalline tin selenide the team makes is spiked with sodium atoms, creating what is known as a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.

Zhao’s team recently reported making an n-type single-crystal tin selenide by spiking it with bromine atoms. And Kanatzidis says his team is now working on making an n-type polycrystalline version. Once n-type and p-type tin selenide devices are paired, researchers should have a clear path to making a new generation of ultra-efficient thermoelectric generators. Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial furnaces to scavenge energy from some of the 65% of fossil fuel energy that winds up as waste heat.

In a significant move towards bolstering India's efforts towards a low-carbon future, the World Bank has approved an additional $1.5 billion in financing. This article explores how this funding aims to support India's transition to cleaner energy sources, informed by global moves toward clean and universal electricity standards and market access, the projects it will fund, and the broader implications for sustainable development.

Commitment to Low-Carbon Transition

India, as one of the world's largest economies, faces substantial challenges in balancing economic growth with environmental sustainability. The country has committed to reducing its carbon footprint and enhancing energy efficiency through various initiatives and partnerships. The World Bank's financing represents a crucial step towards achieving these goals within the context of the global energy transition now underway, providing essential resources to accelerate India's transition towards a low-carbon economy.

Projects Supported by World Bank Funding

The $1.5 billion financing package will support several key projects aimed at advancing India's renewable energy sector and promoting sustainable development practices. These projects may include the expansion of solar and wind energy capacity, enhancing energy efficiency in industries and buildings, improving waste management systems, and fostering innovation in clean technologies.

Collaboration and Partnership

The approval of $1.5 billion in financing underscores the importance of international collaboration and partnership in advancing global climate goals, drawing lessons from China's path to carbon neutrality where relevant. The World Bank's engagement with India demonstrates a commitment to supporting developing countries in their efforts to transition towards sustainable development pathways and build resilience against climate change impacts.

Challenges and Opportunities

Despite the positive impact of the World Bank's financing, India faces challenges such as regulatory barriers, funding constraints, and technological limitations in scaling up renewable energy and energy efficiency initiatives, as well as evolving investor sentiment amid U.S. oil policy shifts that affect energy strategy. Addressing these challenges requires coordinated efforts from government agencies, private sector stakeholders, and international partners to overcome barriers and maximize the impact of investments in sustainable development.

Conclusion

The World Bank's approval of $1.5 billion in financing to support India's low-carbon transition marks a significant milestone in global efforts to combat climate change and promote sustainable development. By investing in renewable energy, enhancing energy efficiency, and fostering innovation, the funding contributes to building a cleaner, more resilient future for India and sets a precedent for international cooperation in addressing pressing environmental challenges worldwide.
