Renewable energy solutions, while answering the energy problems of the United States, also can require billions of gallons of water annually and could cause conflicts over water resources, The New York Times reports.

"When push comes to shove, water could become the real throttle on renewable energy," Michael E. Webber, an assistant professor at the University of Texas Austin who studies the relationship between energy and water, told the Times.

Water efficiency is especially problematic with solar thermal farms, which use mirrors arranged in long troughs. "Trough technology has been more financeable, but now trough presents a separate risk — water," said Nathaniel Bullard, a solar analyst with New Energy Finance, a London research firm. Photovoltaic power plants, while typically more costly and less efficient than solar thermal farms, consume less water, mainly to wash the solar panels.

Solar developer BrightSource Energy is hoping to benefit from the water consumption issue with a technology that places mirrors on towers, producing a higher-temperature steam than from a trough system. It then uses a dry cooling method, which does not adversely affect power output.

In the meantime, water consumption is a contentious issue with state regulators for a number of big solar projects. Already, solar developers in California have had to resort to technologies that are less water intensive because local officials have refused to make large quantities of water available for their projects.

So far California has 35 large-scale solar projects planned that could generate 12,000 megawatts of electricity, each project with different water needs. In the southern part of the state, BrightSource Energy's dry-cooled Ivanpah project would need some 25 million gallons of water a year, mostly to wash mirrors. But in California's Mojave Desert, 705 million gallons would be swallowed up by the wet-cooled Abengoa Solar project, less than half the size of the Ivanpah project.

In Nye County, Nevada, requests for water from renewable energy developers "far exceed the amount of available water," said Joni Eastley, chairwoman of the county commission.

German developer Solar Millennium announced plans to build two large solar farms in the state's arid Amargosa Valley. Hard-hit from the recession, the hundreds of jobs the project would create was welcome news to the Nevada community. But now the people are divided ever since the company disclosed that the project would require 1.3 billion gallons of water a year - about 20 percent of the valley's available water. While some are worried about the impact of the solar farms on the environment, others are hoping to earn money selling their water rights.

As the population increases and renewable energy development continues, water scarcity will become a problem throughout the United States, not just in the arid western states, predicts Daniel M. Kammen, director of the Renewable and Appropriate Energy Laboratory at the University of California, Berkeley.

"When we start getting 20 percent, 30 percent or 40 percent of our power from renewables, water will be a key issue," Kammen told the Times.

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.

Hydro One launches Ultra-Low Overnight Electricity Price Plan

Ultra-Low Overnight Price Plan delivers flexible electricity pricing from Hydro One and the Ontario Energy Board, with TOU, tiered options, off-peak EV charging savings, balanced billing, and an online calculator to optimize bills.

 

Key Points

An Ontario pricing option with ultra-low night rates, helping Hydro One customers save by shifting usage to off-peak.

✅ Four periods with ultra-low overnight rate for EV charging

✅ Compare TOU vs tiered with Hydro One's online calculator

✅ Balanced billing and due date choice support budget control

 

Hydro One has announced that customers have even more choice and flexibility when it comes to how they are billed for electricity with the company's launch of the Ontario Energy Board's new Ultra-Low Overnight Electricity Price Plan for customers. A new survey of Ontario customers, conducted by Innovative Research Group, shows that 74 per cent of Ontarians find having choice between electricity pricing plans useful.

"As their trusted energy advisor, we want our customers to know we have the insights and tools to help them make the right choice when it comes to their electricity plans," said Teri French, Executive Vice President, Safety, Operations and Customer Experience. "We know that choice and flexibility are important to our customers, and we are proud to now offer them a third option so they can select the plan that best fits their lifestyle."

The same survey revealed that fewer than half of Ontarians are familiar with either tiered or the new ultra-low overnight price plans. To better support its customers Hydro One is providing an online calculator to help them choose which pricing plan best suits their lifestyle. The company also offers additional flexibility and assistance in managing household budgets by providing customers with the ability to choose their billing due date and flatten usage spikes from temperature fluctuations through balanced billing.

During the pandemic, Ontario introduced electricity relief to support families, small businesses and farms, complementing these customer options.

"By offering families and small businesses more choice, we are putting them back in control of their energy bills," said Todd Smith, Minister of Energy. "Starting today Hydro One customers have a new option - the Ultra-Low Electricity Price Plan - which could help them save money each year, while making our province's grid more efficient."

Electricity price plan options

  • New Ultra-Low Overnight price plan (ULO): Designed for customers who use more electricity at night, such as those who charge their electric vehicle, this new price plan can help customers keep costs down and take control of their electricity bill by shifting usage to the ultra-low overnight price period and related off-peak electricity rates when province-wide electricity demand is lower.
  • This plan has four price periods that are the same in the summer as they are in the winter and includes an ultra-low overnight rate.
  • Time-of-Use price plan (TOU): TOU provides customers with more control over their electricity bill by adjusting their usage habits with time-of-use rates used in other jurisdictions as well.
  • In this plan, electricity prices change throughout each weekday, when demand is on-peak, and peak hydro rates can affect overall costs.
  • Tiered price plan (RPP): Tiered pricing provides customers with the flexibility to use electricity at any time of day at the same low price up until the threshold is exceeded during the month, after that usage is charged at a higher price.
  • For residential customers, the winter period (November 1 – April 30) threshold is 1,000 kWh per month and the summer period (May 1 – October 31) threshold is 600 kWh per month. 
  • For small business customers, the threshold is 750 kWh throughout the year, while broader stable electricity pricing supports industrial and commercial companies.

Gas-electric hybrid vehicles get a boost in the US from Ford, others

U.S. Hybrid Vehicle Sales Outlook highlights rising hybrid demand as an EV bridge, driven by emissions rules, range anxiety, charging infrastructure gaps, and automaker strategies from Ford, Toyota, and Stellantis across U.S. markets.

 

Key Points

Forecast of U.S. hybrid sales shaped by EV adoption, emissions rules, charging access, and automaker strategies.

✅ S&P sees hybrids at 24% of U.S. sales by 2028

✅ Bridges ICE to EV amid range and charging concerns

✅ Ford, Toyota, Stellantis expand U.S. hybrid lineups

 

Hybrid gasoline-electric vehicles may not be dying as fast as some predicted in the auto sector’s rush to develop all-electric models.

Ford Motor is the latest of several top automakers, including Toyota and Stellantis, planning to build and sell hundreds of thousands of hybrid vehicles in the U.S. over the next five years, industry forecasters told Reuters.

The companies are pitching hybrids as an alternative for retail and commercial customers who are seeking more sustainable transportation, but may not be ready to make the leap to a full electric vehicle.

"Hybrids really serve a lot of America," said Tim Ghriskey, senior portfolio strategist at New York-based investment manager Ingalls & Snyder. "Hybrid is a great alternative to a pure electric vehicle (and) it's an easier sell to a lot of customers."

Interest in hybrids is rebounding as consumer demand for pure electrics has not accelerated as quickly as expected, with EV market share dipping in Q1 2024 according to some analyses. Surveys cite a variety of reasons for tepid EV demand, from high initial cost and concerns about range to lengthy charging times and a shortage of public charging infrastructure in many regions.

“With the tightening of emissions requirements, hybrids provide a cleaner fleet without requiring buyers to take the leap into pure electrics,” said Sam Fiorani, vice president at AutoForecast Solutions.

S&P Global Mobility estimates hybrids will more than triple over the next five years, accounting for 24% of U.S. new vehicle sales in 2028. Sales of pure electrics will claim about 37%, supported by strong U.S. EV sales into 2024 momentum, leaving combustion vehicles — including so-called “mild” hybrids — with a nearly 40% share.

S&P estimates hybrids will account for just 7% of U.S. sales this year, and pure electrics 9%, underscoring that EV sales still lag gas cars as internal combustion engine (ICE) vehicles take more than 80%.

Historically, hybrids have accounted for less than 10% of total U.S. sales, with Toyota’s long-running Prius among the most popular models. The Japanese automaker has consistently said hybrids will play a key role in the company's long-range electrification plans as it slowly ramps up investment in pure EVs.

Ford is the latest to roll out more aggressive hybrid plans. On its second-quarter earnings call in late July, Chief Executive Jim Farley surprised analysts, saying Ford expects to quadruple its hybrid sales over the next five years after earlier promising an aggressive push into all-electric vehicles.

“This transition to EVs will be dynamic,” Farley told analysts. “We expect the EV market to remain volatile until the winners and losers shake out.”

Among Ford’s competitors, General Motors appears to have little interest in hybrids in the U.S., while Stellantis will follow Toyota and Ford’s hedge by offering U.S. buyers a choice of different powertrains, including hybrids, until sales of pure electric vehicles start to take off after mid-decade, a potential EV inflection point according to forecaster GlobalData.

In a statement, GM said it, echoing leadership's view that EVs won't go mainstream until key issues are addressed, "continues to be committed to its all-electric future ... While we will have hybrid vehicles in our global fleet, our focus remains on transitioning our portfolio to electric by 2030.”

Stellantis said hybrids now account for 36% of Jeep Wrangler sales and 19% of Chrysler Pacifica sales. In addition to new pure electric models coming soon, "we are very bullish on hybrids going forward," a spokesperson said.

This year, manufacturers are marketing more than 60 hybrids in the U.S. Toyota and its premium Lexus brand are selling at least 18 different hybrid models, enabling the Japanese automaker to maintain its stranglehold on the sector.

Hyundai and sister brand Kia offer seven hybrid models, with Ford and Lincoln six. Stellantis offers just three, and GM’s sole entry, due out later this year, is a hybrid version of the Chevrolet Corvette sports car.

But hybrids remain in short supply at many U.S. dealerships.

Andrew DiFeo, dealer principal at Hyundai of St. Augustine, south of Jacksonville, FL, doesn't see EV adoption hitting the levels the Biden administration wants until EV charging networks are as ubiquitous as gas stations.

"Hybrids are a great bridge to whatever the future holds,” said DiFeo, adding, “I've got zero in stock (and) I've got customers that want all of them."

Group of premiers band together to develop nuclear reactor technology

Small Modular Reactors in Canada are advancing through provincial collaboration, offering nuclear energy, clean power and carbon reductions for grids, remote communities, and mines, with factory-built modules, regulatory roadmaps, and pre-licensing by the nuclear regulator.

 

Key Points

Compact, factory-built nuclear units for clean power, cutting carbon for grids, remote communities, and industry.

✅ Provinces: Ontario, Saskatchewan, New Brunswick collaborate

✅ Targets coal replacement, carbon cuts, clean baseload power

✅ Modular, factory-made units; 5-10 year deployment horizon

 

The premiers of Ontario, Saskatchewan and New Brunswick have committed to collaborate on developing nuclear reactor technology in Canada. 

Doug Ford, Scott Moe and Blaine Higgs made the announcement and signed a memorandum of understanding on Sunday in advance of a meeting of all the premiers. 

They will be working on the research, development and building of small modular reactors as a way to help their individual provinces reduce carbon emissions and move away from non-renewable energy sources like coal. 

Small modular reactors are easy to construct, are safer than large reactors and are regarded as cleaner energy than coal, the premiers say. They can be small enough to fit in a school gym. 

SMRs are actually not very close to entering operation in Canada, though Ontario broke ground on its first SMR at Darlington recently, signaling early progress. Natural Resources Canada released an "SMR roadmap" last year, with a series of recommendations about regulation readiness and waste management for SMRs.

In Canada, about a dozen companies are currently in pre-licensing with the Canadian Nuclear Safety Commission, which is reviewing their designs.

"Canadians working together, like we are here today, from coast to coast, can play an even larger role in addressing climate change in Canada and around the world," Moe said.  

Canada's Paris targets are to lower total emissions 30 per cent below 2005 levels by 2030, and nuclear's role in climate goals has been emphasized by the federal minister in recent remarks. Moe says the reactors would help Saskatchewan reach a 70 per cent reduction by that year.

The provinces' three energy ministries will meet in the new year to discuss how to move forward and by the fall a fully-fledged strategy for the reactors is expected to be ready.

However, don't expect to see them popping up in a nearby field anytime soon. It's estimated it will take five to 10 years before they're built. 

Ford lauds economic possibilities
The provincial leaders said it could be an opportunity for economic growth, estimating the Canadian market for this energy at $10 billion and the global market at $150 billion.

Ford called it an "opportunity for Canada to be a true leader." At a time when Ottawa and the provinces are at odds, Higgs said it's the perfect time to show unity. 

"It's showing how provinces come together on issues of the future." 

P.E.I. premier predicts unity at Toronto premiers' meeting
No other premiers have signed on to the deal at this point, but Ford said all are welcome and "the more, the merrier."

But developing new energy technologies is a daunting task. Higgs admitted the project will need national support of some kind, though he didn't specify what. The agreement signed by the premiers is also not binding. 

About 8.6 per cent of Canada's electricity comes from coal-fired generation. In New Brunswick that figure is much higher — 15.8 per cent — and New Brunswick's small-nuclear debate has intensified as New Brunswick Premier Blaine Higgs has said he worries about his province's energy producers being hit by the federal carbon tax.

Ontario has no coal-fired power plants, and OPG's SMR commitment aligns with its clean electricity strategy today. In Saskatchewan, burning coal generates 46.6 per cent of the province's electricity.

How would it work?
The federal government describes small modular reactors (SMRs) as the "next wave of innovation" in nuclear energy technology, and collaborations like the OPG and TVA partnership are advancing development efforts, and an "important technology opportunity for Canada."

Traditional nuclear reactors used in Canada typically generate about 800 megawatts of electricity, and Ontario is exploring new large-scale nuclear plants alongside SMRs, or enough to power about 600,000 homes at once (assuming that 1 megawatt can power about 750 homes).

The International Atomic Energy Agency (IAEA), the UN organization for nuclear co-operation, considers a nuclear reactor to be "small" if it generates under 300 megawatts.

Designs for small reactors ranging from just 3 megawatts to 300 megawatts have been submitted to Canada's nuclear regulator, the Canadian Nuclear Safety Commission, for review as part of a pre-licensing process, while plans for four SMRs at Darlington outline a potential build-out pathway that regulators will assess.

Ford rallying premiers to call for large increase in federal health transfers
Such reactors are considered "modular" because they're designed to work either independently or as modules in a bigger complex (as is already the case with traditional, larger reactors at most Canadian nuclear power plants). A power plant could be expanded incrementally by adding additional modules.

Modules are generally designed to be small enough to make in a factory and be transported easily — for example, via a standard shipping container.

In Canada, there are three main areas where SMRs could be used:

Traditional, on-grid power generation, especially in provinces looking for zero-emissions replacements for CO2-emitting coal plants.
Remote communities that currently rely on polluting diesel generation.
Resource extraction sites, such as mining and oil and gas.

Turkish powership to generate electricity from LNG in Senegal

Karpowership LNG powership in Senegal will supply 15% of the grid, a 235 MW floating power plant bound for Dakar, enabling fast deployment, base-load electricity, and cleaner natural gas generation for West Africa.

 

Key Points

A 235 MW floating plant supplying 15% of Senegal's grid with fast, reliable, lower-emission LNG electricity.

✅ 235 MW LNG-ready floating plant meets 15% of Senegal's demand

✅ Rapid deployment: commercial operations expected early October

✅ Cleaner natural gas conversion planned after six months

 

Turkey's Karpowership company, the designer and builder of the world's first floating power plants and the global brand of Karadeniz Holding, will meet 15% of Senegal's electricity needs from liquefied natural gas (LNG) with the 235-megawatt (MW) powership Ayşegül Sultan, which started its voyage from Turkey to Senegal, where an African Development Bank review of a coal plant is underway, on Sunday.

Karpowership, operating 22 floating power plants in more than 10 countries around the world, where France's first offshore wind turbine is now producing electricity, has invested over $5 billion in this area.

In a statement to members of the press at Karmarine Shipyard, Karpowership Trade Group Chair Zeynep Harezi said they aimed to provide affordable electricity to countries in need of electricity quickly and reliably, as projects like the Egypt-Saudi power link expand regional grids, adding that they could commission energy ships capable of generating the base electric charge of the countries, as tidal power in Nova Scotia begins supplying the grid, in a period of about a month.

Harezi recalled that Karpowership commissioned the first floating energy ship in 2007 in Iraq, followed by Lebanon, Ghana, Indonesia, Mozambique, Zambia, Gambia, Sierra Leone, Sudan, Cuba, Guinea Bissau and Senegal, while Scottish tidal power demonstrates marine potential as well. "We meet the electricity needs of 34 million people in many countries," she stressed. Harezi stated that the energy ships, all designed and produced by Turkish engineers, use liquid fuel, but all ships can covert to the second fuel.

Considering the impact of electricity production on the environment, Harezi noted that they plan to convert the entire fleet from liquid fuel to natural gas, with complementary approaches like power-to-gas in Europe helping integrate renewables. "With a capacity of 480 megawatts each, the world's largest floating energy vessels operate in Indonesia and Ghana. The conversion to gas has been completed in our project in Indonesia. We have also initiated the conversion of the Ghana vessel into gas," she said.

Harezi explained that they would continue to convert their fleets to natural gas in the coming period. "Our 235-MW floating electric vessel, the Ayşegül Sultan, sets sail today to meet 15% of Senegal's electricity needs on its own. After an approximately 20-day cruise, the vessel will reach Dakar, the capital of Senegal, and will begin commercial operation in early October," Harezi continued. "We plan to use liquid fuel as bridging fuel in the first six months. At the end of the first six months, we will start to produce electricity from LNG on our ship. Thus, Ayşegül Sultan will be the first project to generate electricity from LNG in Africa, while the world's most powerful tidal turbine is delivering power to the grid, officials said. Our floating power plant to be sent to Mozambique is designed to generate electricity from LNG. It is also scheduled to start operations in the next year."

Brazilian electricity workers call for 72-hour strike

Eletrobras Privatization Strike sparks a 72-hour CNE walkout by Brazil's electricity workers, opposing asset sell-offs and grid privatization while pledging essential services; unions target President Wilson Ferreira Jr. over energy-sector reforms.

 

Key Points

A 72-hour CNE walkout by Brazil's electricity workers opposing Eletrobras sell-offs, while keeping essential services.

✅ 72-hour strike led by CNE unions and federations

✅ Targets privatization plans and leadership at Eletrobras

✅ Essential services maintained to avoid consumer impact

 

Brazil's national electricity workers' collective (CNE) has called for a 72-hour strike to protest the privatization of state-run electric company Eletrobras and its subsidiaries.

The CNE, which gathers the electricity workers' confederation, federations, unions and associations, said the strike is to begin at Monday midnight (0300 GMT) and last through midnight Wednesday, even as some utilities elsewhere have considered asking staff to live on site to maintain operations.

Workers are demanding the ouster of Eletrobras President Wilson Ferreira Jr., who they say is the leading promoter of the privatization move.

Some 24,000 workers are expected to take part in the strike. However, the CNE said it will not affect consumers by ensuring essential services, a pledge echoed by utilities managing costs elsewhere such as Manitoba Hydro's unpaid days off during the pandemic.

#google#

Eletrobras accounts for 32 percent of Brazil's installed energy generation capacity, mainly via hydroelectric plants. Besides, it also operates nuclear and thermonuclear plants, and solar and wind farms, reflecting trends captured by young Canadians' interest in electricity jobs in recent years.

The company distributes electricity in six northern and northeastern states, and handles 47 percent of the nation's electricity transmission lines, even as a U.S. grid pandemic warning has highlighted reliability risks.

The government owns a 63-percent stake in the company, a reminder that public policy shapes the sector, similar to Canada's future-of-work investment initiatives announced recently.
