First Solar Inc, the worlds largest thinfilm solar panel producer, has set up a Silicon Valley lab for a thinfilm technology with the potential for higher efficiency at a lower cost, sources said.

A big move toward panels based on CIGS, or copper indium gallium diselenide, technology would mark a major shift for First Solar into an area pioneered by others and would also lend support to critics who see limited room to improve the efficiency of the companys current cadmium telluride panels.

The company has said its cadtel panels can exceed 11 percent efficiency in converting sunlight to electricity, and it aims to improve that further.

First Solar acknowledged it has a small research and development unit in Silicon Valley but declined to comment further.

The Arizonabased company made a name for itself with these thinfilm panels that are less efficient than standard panels based on computer processorstyle silicon semiconductors, but are much cheaper to produce per watt of output.

CIGS offers the hope of cheap thinfilm production costs with efficiency near the best of silicon solar cells, which can be as high as 20 percent.

First Solar, which has never discussed its Silicon Valley operations publicly, has had a research and development unit there for a couple of years, five industry sources with knowledge of the operation said.

The company is looking at lowcost processes to manufacture CIGS panels, one of the people said, though two other sources said the CIGS research appears to be in its initial stages.

Most First Solar operations are outside California, with its corporate headquarters in Tempe, Arizona, and factories in Ohio and Malaysia. The Silicon Valley unit, however, would benefit from the abundant engineering and semiconductorrelated talent available in the San Francisco Bay Area.

In lab conditions, CIGS has demonstrated the efficiency of silicon cells. The U.S. Department of Energys National Renewable Energy Laboratory set a new efficiency record of 19.9 percent for CIGS, nearing the record for crystalline silicon cells, but no company has come close to that in the factory.

First Solar Chief Financial Officer Jens Meyerhoff, when asked about new technologies at an industry conference last month, said the company monitors emerging technologies closely but hasnt seen major competitive threats.

First Solar has an inhouse effort that deals with assessment and evaluation of alternate material sets and technologies, Meyerhoff added.

The company has never publicly said it is doing research on CIGSbased solar panels.

Silicon Valley is home to many startups that are looking to commercialize CIGSbased panels, including MiaSole, Nanosolar and Solyndra.

CIGS has caught the attention of researchers and companies as it has the potential to match the photovoltaic PV efficiency of crystalline silicon cells.

If you can do it, its probably the cheapest PV solution out there, said Travis Bradford, Director of Prometheus Institute for Sustainable Development.

Ascent Solar, a publicly traded CIGSbased solar company, has said it has achieved efficiency as high as 11.7 percent for its modules.

Sales of CIGS panels are tiny compared to First Solars sales of cadtel panels, or those made by large competitors Suntech Power Holdings and SunPower Corp.

The cost of building CIGS cells is expected to fall to 50 cents per watt in the coming years, less than half the level of current silicon cells.

Doug Ford's New Stance on Wind Power in Ontario

Ontario Wind Power Policy Shift signals renewed investment in renewable energy, wind farms, and grid resilience, aligning with climate goals, lower electricity costs, job creation, and turbine technology for cleaner, diversified power.

 

Key Points

A provincial pivot to expand wind energy, meet climate goals, lower costs, and boost jobs across Ontario’s power system.

✅ Diversifies Ontario's grid with scalable renewable capacity.

✅ Targets emissions cuts while stabilizing electricity prices.

✅ Spurs rural investment, supply chains, and skilled jobs.

 

Ontario’s energy landscape is undergoing a significant transformation as Premier Doug Ford makes a notable shift in his approach to wind power. This change represents a strategic pivot in the province’s energy policy, potentially altering the future of Ontario’s power generation, environmental goals, and economic prospects.

The Backdrop: Ford’s Initial Stance on Wind Power

When Doug Ford first assumed the role of Premier in 2018, his administration was marked by a strong stance against renewable energy projects, including wind power, with Ford later saying he was proud of tearing up contracts as part of this shift. Ford’s government inherited a legacy of ambitious renewable energy commitments from the previous Liberal administration under Kathleen Wynne, which had invested heavily in wind and solar energy. The Ford government, however, was critical of these initiatives, arguing that they resulted in high energy costs and a surplus of power that was not always needed.

In 2019, Ford’s government began rolling back several renewable energy projects, including wind farms, and was soon tested by the Cornwall wind farm ruling that scrutinized a cancellation. This move was driven by a promise to reduce electricity bills and cut what was perceived as wasteful spending on green energy. The cancellation of several wind projects led to frustration among environmental advocates and the renewable energy sector, who viewed the decision as a setback for Ontario’s climate goals.

The Shift: Embracing Wind Power

Fast forward to 2024, and Premier Ford’s administration is taking a markedly different approach. The recent policy shift, which moves to reintroduce renewable projects, indicates a newfound openness to wind power, reflecting a broader acknowledgment of the changing dynamics in energy needs and environmental priorities.

Several factors appear to have influenced this shift:

  1. Rising Energy Demands and Climate Goals: Ontario’s growing energy demands, coupled with the pressing need to address climate change, have necessitated a reevaluation of the province’s energy strategy. As Canada commits to reducing greenhouse gas emissions and transitioning to cleaner energy sources, wind power is increasingly seen as a crucial component of this strategy. Ford’s change in direction aligns with these national and global goals.

  2. Economic Considerations: The economic landscape has also evolved since Ford’s initial opposition to wind power. The cost of wind energy has decreased significantly over the past few years, making it a more competitive and viable option compared to traditional energy sources, as competitive wind power gains momentum in markets worldwide. Additionally, the wind energy sector promises substantial job creation and economic benefits, which are appealing in the context of post-pandemic recovery and economic growth.

  3. Public Opinion and Pressure: Public opinion and advocacy groups have played a role in shaping policy. There has been a growing demand from Ontarians for more sustainable and environmentally friendly energy solutions. The Ford administration has been responsive to these concerns, recognizing the importance of addressing public and environmental pressures.

  4. Technological Advancements: Advances in wind turbine technology have improved efficiency and reduced the impact on wildlife and local communities. Modern wind farms are less intrusive and more effective, addressing some of the concerns that were previously associated with wind power.

Implications of the Policy Shift

The implications of Ford’s shift towards wind power are far-reaching. Here are some key areas affected by this change:

  1. Energy Portfolio Diversification: By reembracing wind power, Ontario will diversify its energy portfolio, reducing its reliance on fossil fuels and increasing the proportion of renewable energy in the mix. This shift will contribute to a more resilient and sustainable energy system.

  2. Environmental Impact: Increased investment in wind power will contribute to Ontario’s efforts to combat climate change. Wind energy is a clean, renewable source that produces no greenhouse gas emissions during operation. This aligns with broader environmental goals and helps mitigate the impact of climate change.

  3. Economic Growth and Job Creation: The wind power sector has the potential to drive significant economic growth and create jobs. Investments in wind farms and associated infrastructure can stimulate local economies, particularly in rural areas where many wind farms are located.

  4. Energy Prices: While the initial shift away from wind power was partly motivated by concerns about high energy costs, including exposure to costly cancellation fees in some cases, the decreasing cost of wind energy could help stabilize or even lower electricity prices in the long term. As wind power becomes a larger component of Ontario’s energy supply, it could contribute to a more stable and affordable energy market.

Moving Forward: Challenges and Opportunities

Despite the positive aspects of this policy shift, there are challenges to consider, and other provinces have faced setbacks such as the Alberta wind farm scrapped by TransAlta that illustrate potential hurdles. Integrating wind power into the existing grid requires careful planning and investment in grid infrastructure. Additionally, addressing local concerns about wind farms, such as their impact on landscapes and wildlife, will be crucial to gaining broader acceptance.

Overall, Doug Ford’s shift towards wind power represents a significant and strategic change in Ontario’s energy policy. It reflects a broader understanding of the evolving energy landscape and the need for a sustainable and economically viable energy future. As the province navigates this new direction, the success of this policy will depend on effective implementation, ongoing stakeholder engagement, and a commitment to balancing environmental, economic, and social considerations, even as the electricity future debate continues among party leaders.

TTC Bans Lithium-Ion-Powered E-Bikes and Scooters During Winter Months for Safety

TTC Winter E-Bike and E-Scooter Ban addresses lithium-ion battery safety, mitigating fire risk on Toronto public transit during cold weather across buses, subways, and streetcars, while balancing micro-mobility access, infrastructure gaps, and evolving regulations.

 

Key Points

A seasonal TTC policy limiting lithium-ion e-bikes and scooters on transit in winter to cut battery fire risk.

✅ Targets lithium-ion fire hazards in confined transit spaces

✅ Applies Nov-Mar across buses, subways, and streetcars

✅ Sparks debate on equity, accessibility, and policy alternatives

 

The Toronto Transit Commission (TTC) Board recently voted to implement a ban on lithium-ion-powered electric bikes (e-bikes) and electric scooters during the winter months, a decision that reflects growing safety concerns. This new policy has generated significant debate within the city, particularly regarding the role of these transportation modes in the lives of Torontonians, and the potential risks posed by the technology during cold weather.

A Growing Safety Concern

The move to ban lithium-ion-powered e-bikes and scooters from TTC services during the winter months stems from increasing safety concerns related to battery fires. Lithium-ion batteries, commonly used in e-bikes and scooters, are known to pose a fire risk, especially in colder temperatures, and as systems like Metro Vancouver's battery-electric buses expand, robust safety practices are paramount. In recent years, Toronto has experienced several high-profile incidents involving fires caused by these batteries. In some cases, these fires have occurred on TTC property, including on buses and subway cars, raising alarm among transit officials.

The TTC Board's decision was largely driven by the fear that the cold temperatures during winter months could make lithium-ion batteries more prone to malfunction, leading to potential fires. These batteries are particularly vulnerable to damage when exposed to low temperatures, which can cause them to overheat or fail during charging or use. Since public transit systems are densely populated and rely on close quarters, the risk of a battery fire in a confined space such as a bus or subway is considered too high.

The New Ban

The new rule, which is expected to take effect in the coming months, will prohibit e-bikes and scooters powered by lithium-ion batteries from being brought onto TTC vehicles, including buses, streetcars, and subway trains, even as the agency rolls out battery electric buses across its fleet, during the winter months. While the TTC had previously allowed passengers to bring these devices on board, it had issued warnings regarding their safety. The policy change reflects a more cautious approach to mitigating risk in light of growing concerns.

The winter months, typically from November to March, are when these batteries are at their most vulnerable. In addition to environmental factors, the challenges posed by winter weather—such as snow, ice, and the damp conditions—can exacerbate the potential for damage to these devices. The TTC Board hopes the new ban will prevent further incidents and keep transit riders safe.

Pushback and Debate

Not everyone agrees with the TTC Board's decision. Some residents and advocacy groups have expressed concern that this ban unfairly targets individuals who rely on e-bikes and scooters as an affordable and sustainable mode of transportation, while international examples like Paris's e-scooter vote illustrate how contentious rental devices can be elsewhere, adding fuel to the debate. E-bikes, in particular, have become a popular choice among commuters who want an eco-friendly alternative to driving, especially in a city like Toronto, where traffic congestion can be severe.

Advocates argue that instead of an outright ban, the TTC should invest in safer infrastructure, such as designated storage areas for e-bikes and scooters, or offer guidelines on how to safely store and transport these devices during winter, and, in assessing climate impacts, consider Canada's electricity mix alongside local safety measures. They also point out that other forms of electric transportation, such as electric wheelchairs and mobility scooters, are not subject to the same restrictions, raising questions about the fairness of the new policy.

In response to these concerns, the TTC has assured the public that it remains committed to finding alternative solutions that balance safety with accessibility. Transit officials have stated that they will continue to monitor the situation and consider adjustments to the policy if necessary.

Broader Implications for Transportation in Toronto

The TTC’s decision to ban lithium-ion-powered e-bikes and scooters is part of a broader conversation about the future of transportation in urban centers like Toronto. The rise of electric micro-mobility devices has been seen as a step toward reducing carbon emissions and addressing the city’s growing congestion issues, aligning with Canada's EV goals that push for widespread adoption. However, as more people turn to e-bikes and scooters for daily commuting, concerns about safety and infrastructure have become more pronounced.

The city of Toronto has yet to roll out comprehensive regulations for electric scooters and bikes, and this issue is further complicated by the ongoing push for sustainable urban mobility and pilots like driverless electric shuttles that test new models. While transit authorities grapple with safety risks, the public is increasingly looking for ways to integrate these devices into a broader, more holistic transportation system that prioritizes both convenience and safety.

The TTC’s decision to ban lithium-ion-powered e-bikes and scooters during the winter months is a necessary step to address growing safety concerns in Toronto's public transit system. Although the decision has been met with some resistance, it highlights the ongoing challenges in managing the growing use of electric transportation in urban environments, where initiatives like TTC's electric bus fleet offer lessons on scaling safely. With winter weather exacerbating the risks associated with lithium-ion batteries, the policy seeks to reduce the chances of fires and ensure the safety of all transit users. As the city moves forward, it will need to find ways to balance innovation with public safety to create a more sustainable and safe urban transportation network.

Florida Court Blocks Push to Break Electricity Monopolies

Florida Electricity Deregulation Ruling highlights the Florida Supreme Court decision blocking a ballot measure on retail choice, preserving utility monopolies for NextEra and Duke Energy, while similar deregulation efforts arise in Virginia and Arizona.

 

Key Points

A high court decision removing a retail choice ballot measure, keeping Florida utility monopolies intact for incumbents.

✅ Petition language deemed misleading for 2020 ballot

✅ Preserves NextEra and Duke Energy market dominance

✅ Similar retail choice pushes in VA and AZ

 

Florida’s top court ruled against a proposed constitutional amendment that would have allowed customers to pick their electricity provider, even as Florida solar incentives face rejection by state leaders, threatening monopolies held by utilities such as NextEra Energy Inc. and Duke Energy Corp.

In a ruling Thursday, the court said the petition’s language is “misleading” and doesn’t comply with requirements to be included on the 2020 ballot, reflecting debates over electricity pricing changes at the federal level. The measure’s sponsor, Citizens for Energy Choice, said the move ends the initiative, even as electricity future advocacy continues nationwide.

“While we were confident in our plan to gather the remaining signatures required, we cannot overcome this last obstacle,” the group’s chair, Alex Patton, noting ongoing energy freedom in the South efforts, said in a statement.

The proposed measure was one of several efforts underway to deregulate U.S. electricity markets, including New York’s review of retail energy markets this year. Earlier this week, two Virginia state lawmakers unveiled a bill to allow residents and businesses to pick their electricity provider, threatening Dominion Energy Inc.’s longstanding local monopoly. And in Arizona, where Arizona Public Service Co. has long reigned, regulators are considering a similar move, while in New England Hydro-Quebec’s export bid has been energized by a court decision.

Tesla updates Supercharger billing to add cost of electricity use for other than charging

Tesla Supercharger Billing Update details kWh-based pricing that now includes HVAC, battery thermal management, and other HV loads during charging sessions, improving cost transparency across pay-per-use markets and extreme climate scenarios.

 

Key Points

Tesla's update bills for kWh used by HVAC, battery heating, and HV loads during charging, reflecting true energy costs.

✅ kWh charges now include HVAC and battery thermal management

✅ Expect 10-25 kWh increases in extreme climates during sessions

✅ Some regions still bill per minute due to regulations

 

Tesla has updated its Supercharger billing policy to add the cost of electricity use for things other than charging, like HVAC, battery thermal management, etc, while charging at a Supercharger station, a shift that impacts overall EV charging costs for drivers. 

For a long time, Tesla’s Superchargers were free to use, or rather the use was included in the price of its vehicles. But the automaker has been moving to a pay-to-use model over the last two years in order to finance the growth of the charging network amid the Biden-era charging expansion in the United States.

Not charging owners for the electricity enabled Tesla to wait on developing a payment system for its Supercharger network.

It didn’t need one for the first five years of the network, and now the automaker has been fine-tuning its approach to charge owners for the electricity they consume as part of building better charging networks across markets.

At first, it meant fluctuating prices, and now Tesla is also adjusting how it calculates the total power consumption.

Last weekend, Tesla sent a memo to its staff to inform them that they are updating the calculation used to bill Supercharging sessions in order to take into account all the electricity used:

The calculation used to bill for Supercharging has been updated. Owners will also be billed for kWhs consumed by the car going toward the HVAC system, battery heater, and other HV loads during the session. Previously, owners were only billed for the energy used to charge the battery during the charging session.

Tesla says that the new method should more “accurately reflect the value delivered to the customer and the cost incurred by Tesla,” which mirrors recent moves in its solar and home battery pricing strategy as well.

The automaker says that customers in “extreme climates” could see a difference of 10 to 25 kWh for the energy consumed during a charging session:

Owners may see a noticeable increase in billed kWh if they are using energy-consuming features while charging, e.g., air conditioning, heating etc. This is more likely in extreme climates and could be a 10-25 kWh difference from what a customer experienced previously, as states like California explore grid-stability uses for EVs during peak events.

Of course, this is applicable where Tesla is able to charge by the kWh for charging sessions. In some markets, regulations push Tesla to charge by the minute amid ongoing fights over charging control between utilities and private operators.

Electrek’s Take
It actually looks like an oversight from Tesla in the first place. It’s fair to charge for the total electricity used during a session, and not just what was used to charge your battery pack, since Tesla is paying for both, even as some states add EV ownership fees like the Texas EV fee that further shape costs.

However, I wish Tesla would have a clearer way to break down the charging sessions and their costs.

There have been some complaints about Tesla wrongly billing owners for charging sessions, and this is bound to create more confusion if people see a difference between the kWhs gained during charging and what is shown on the bill.

Saskatchewan to credit solar panel owners, but not as much as old program did

Saskatchewan Solar Net Metering Program lets rooftop solar users offset at retail rate while earning 7.5 cents/kWh credits for excess energy; rebates are removed, SaskPower balances grid costs with a 100 kW cap.

 

Key Points

An updated SaskPower plan crediting rooftop solar at 7.5 cents/kWh, offsetting usage at retail rate, without rebates.

✅ Excess energy credited at 7.5 cents/kWh

✅ Offsets on-site use at retail electricity rates

✅ Up to 100 kW generation; no program capacity cap

 

Saskatchewan has unveiled a new program that credits electricity customers for generating their own solar power, but it won’t pay as much as an older program did or reimburse them with rebates for their costs to buy and install equipment.

The new net metering program takes effect Nov. 1, and customers will be able to use solar to offset their own power use at the retail rate, similar to UK households' right to sell power in comparable schemes, though program details differ.

But they will only get 7.5 cents per kilowatt hour credit on their bills for excess energy they put back into the grid, as seen in Duke Energy payment changes in other jurisdictions, rather than the 14 cents in the previous program.

Dustin Duncan, the minister responsible for Crown-owned SaskPower, says the utility had to consider the interests of people wanting to use rooftop solar and everyone else who doesn’t have or can’t afford the panels, who he says would have to make up for the lost revenue.

Duncan says the idea is to create a green energy option, with wind power gains highlighting broader competitiveness, while also avoiding passing on more of the cost of the system to people who just cannot afford solar panels of their own.

Customers with solar panels will be allowed to generate up to 100 kilowatts of power against their bills.

“It’s certainly my hope that this is going to provide sustainability for the industry, as illustrated by Alberta's renewable surge creating jobs, that they have a program that they can take forward to their potential customers, while at the same time ensuring that we’re not passing onto customers that don’t have solar panels more cost to upkeep the grid,” Duncan said Tuesday.

Saskatchewan NDP leader Ryan Meili said he believes eliminating the rebate and cutting the excess power credit will kill the province’s solar energy, a concern consistent with lagging solar demand in Canada in recent national reports, he said.

“(Duncan) essentially made it so that any homeowner who wants to put up panels would take up to twice as long to pay it back, which effectively prices everybody in the small part of the solar production industry — the homeowners, the farms, the small businesses, the small towns — out of the market,” Meili said.

The province’s old net metering program hit its 16 megawatt capacity ahead of schedule, forcing the program to shut down, while disputes like the Manitoba Hydro solar lawsuit have raised questions about program management elsewhere. It also had a rebate of 20 per cent of the cost of the system, but that rebate has been discontinued.

The new net metering program won’t have any limit on program capacity, or an end date.

According to Duncan, the old program would have had a net negative impact to SaskPower of about $54 million by 2025, but this program will be much less — between $4 million and $5 million.

Duncan said other provinces either have already or are in the process of moving away from rebates for solar equipment, including Nova Scotia's proposed solar charge and similar reforms, and away from the one-to-one credits for power generation.

Britain got its cleanest electricity ever during lockdown

UK Clean Electricity Record as wind, solar, and biomass boost renewable energy output, slashing carbon emissions and wholesale power prices during lockdown, while lower demand challenges grid balancing and drives a drop to 153 g/kWh.

 

Key Points

A milestone where wind, solar and biomass lifted renewables, cutting carbon intensity to 153 g/kWh during lockdown.

✅ Carbon intensity averaged 153 g/kWh in Q2 2020.

✅ Renewables output rose 32% via wind, solar, biomass.

✅ Wholesale power prices slumped 42% amid lower demand.

 

U.K electricity has never been cleaner. As wind, solar and biomass plants produced more power than ever in the second quarter, with a new wind generation record set, carbon emissions fell by a third from a year earlier, according to Drax Electric Insight’s quarterly report. Power prices slumped 42 per cent as demand plunged during lockdown. Total renewable energy output jumped 32 per cent in the period, as wind became the main source of electricity at times.

“The past few months have given the country a glimpse into the future for our power system, with higher levels of renewable energy, as wind led the power mix, and lower demand making for a difficult balancing act,”said  Iain Staffell, from Imperial College London and lead author of the report.

The findings of the report point to the impact energy efficiency can have on reducing emissions, as coal's share fell to record lows across the electricity system. Millions of people furloughed or working from home and shuttered shops up and down the country resulted in daily electricity demand dropping about 10% and being about four gigawatts lower than expected in the three months through June.

Average carbon emissions fell to a new low of 153 grams per kWh of electricity consumed over the quarter, as coal-free generation records were extended, even though low-carbon generation stalled in 2019, according to the report.
