I think few people realize how much water is used for food production.

The numbers are quite mind-boggling, and a side effect of this is that a lot of energy is used to pump that water. So much so that the Idaho Power Company has started paying farmers to turn off their water pumps in the afternoon (during peak demand), resulting in a reduction in electricity consumption of "slightly over 5 percent" during hot afternoons.

While this is good, so much more could be done.

Some experts say that irrigating in the late afternoons is inefficient anyway, because some of the water will evaporate in the heat of the day. However Sid Erwin, who farms alfalfa and other crops in southern Idaho and is vice president of the Idaho Irrigation Pumpers Association, said that most local farms — including his — ran their pumps 24 hours a day. There is not enough evaporation to justify paying to send a worker to turn off the pumps in the afternoon, he said.

With the power company paying, the calculus changes. Mr. Erwin estimates that he could save upwards of $10,000 from the program — out of a $40,000 annual pumping bill.

That, he said, should be enough to “pay a man or two or three men” to make sure the pumps are properly turned off and on.

So they run the pumps 24 hours a day because it's less expensive than turning off the pumps? How about a timer system that automatically turns off the pumps at set times? If it saves about 1/4 a year in pumping costs (not to mention water costs), it seems like it would pay for itself pretty quickly.

Maybe power companies could even pay for these timer systems.

But even that would be a half solution. The real way to save both more electricity and water would be to use much more efficient irrigation techniques, such as drip irrigation. Arid countries have developed great expertise, but there's no reason why those techniques shouldn't be used everywhere. It's not because something is more plentiful that you should waste more of it.

NRC Begins Special Inspection at River Bend Nuclear Power Plant

NRC Special Inspection at River Bend reviews failures of portable emergency diesel generators, nuclear safety measures, and Entergy Operations actions after Fukushima; off-site power loss readiness, remote COVID-19 oversight, and corrective action plans are assessed.

 

Key Points

An NRC review of generator test failures at River Bend, assessing nuclear safety, root causes, and corrective actions.

✅ Evaluates failures of portable emergency diesel generators

✅ Reviews causal analyses and adequacy of corrective actions

✅ Remote COVID-19 oversight; public report expected within 45 days

 

The Nuclear Regulatory Commission has begun a special inspection at the River Bend nuclear power plant, part of broader oversight that includes the Turkey Point renewal application, to review circumstances related to the failure of five portable emergency diesel generators during testing. The plant, operated by Entergy Operations, is located in St. Francisville, La., as nations like France outage risks continue to highlight broader reliability concerns.

The generators are used to supply power to plant systems in the event of a prolonged loss of off-site electrical power coupled with a failure of the permanently installed emergency generators, a concern underscored by incidents such as the SC nuclear plant leak that shut down production for weeks. These portable generators were acquired as part of the facility's safety enhancements mandated by the NRC following the 2011 accident at the Fukushima Dai-ichi facility in Japan, and amid constraints like France limiting output from warm rivers, the emphasis on resilience remains.

The three-member NRC team will develop a chronology of the test failures and evaluate the licensee's causal analyses and the adequacy of corrective actions, informed by lessons from cases like Davis-Besse closure stakes that underscore risk management.

Due to the COVID-19 pandemic, they will complete most of their work remotely, while other regions address constraints such as high river temperatures limiting output for nuclear stations. An inspection report documenting the team's findings, released as global nuclear project milestones continue across the sector, will be publicly available within 45 days of the end of the inspection.

EU draft shows plan for more fixed-price electricity contracts

EU Electricity Market Reform advances two-way CfDs, PPAs, and fixed-price tariffs to cut volatility, support renewables and nuclear, stabilize investor revenues, and protect consumers from price spikes across wholesale power markets.

 

Key Points

An EU plan expanding two-way CfDs, PPAs, and fixed-price contracts to curb price swings and support low-carbon power.

✅ Two-way CfDs return excess revenues to consumers

✅ Boosts PPAs and fixed-price retail options

✅ Targets renewables, nuclear; limits fossil exposure

 

The European Union wants to expand the use of contracts that pay power plants a fixed price for electricity, a draft proposal showed, as part of an electricity market revamp to shield European consumers from big price swings.

The European Commission pledged last year to reform the EU's electricity market rules, after record-high gas prices, caused by cuts to Russian flows, sent power prices soaring, prompting debates over gas price cap strategies in response.

A draft of the EU executive's proposal, seen by Reuters on Tuesday and due to be published on Mar. 16, steered clear of the deep redesign of the electricity market that some member states have called for, even as nine EU countries opposed sweeping reforms as a fix earlier in the crisis, suggesting instead limited changes to nudge countries towards more predictable, fixed-price power contracts.

If EU countries want to support new investments in wind, solar, geothermal, hydropower and nuclear electricity, for example - a point over which France and Germany have wrestled - they should use a two-way contract for difference (CfD) or an equivalent contract, the draft said.

The aim is to provide a stable revenue stream to investors, and help make consumers' energy bills less volatile, even though rolling back electricity prices is tougher than it appears. Restricting this support to renewable and low-carbon electricity also aims to speed up Europe's shift away from fossil fuels.

Two-way CfDs offer generators a fixed "strike price" for their electricity, regardless of the price in short-term energy markets. If the market price is above the CfD strike price, then the extra revenue the generator receives should be handed out to final electricity consumers, the draft EU document said.

Countries should also make it easier for power buyers to sign power purchase agreements (PPA) - another type of long-term contract to directly buy electricity from a generator.

Governments should also make sure consumers have access to fixed-price electricity contracts - echoing France's new electricity pricing scheme to reassure Brussels - giving them the option to avoid a contract that would expose them to volatile prices swings in energy markets, the draft said.

If European energy prices were to spike to extreme levels again, the Commission suggested allowing national governments to temporarily intervene to fix prices while weighing emergency measures to limit prices where needed, and offer consumers and small businesses a share of their electricity at a lower price.

Abu Dhabi seeks investors to build hydrogen-export facilities

ADNOC Hydrogen Export Projects target global energy transition, courting investors and equity stakes for blue and green hydrogen, ammonia shipping, CCS at Ruwais, and long-term supply contracts across power, transport, and industrial sectors.

 

Key Points

ADNOC plans blue and green hydrogen exports, leveraging Ruwais, CCS, and ammonia to secure long-term supply.

✅ Blue hydrogen via gas reforming with CCS; ammonia for shipping.

✅ Green hydrogen from solar-powered electrolysis under development.

✅ Ruwais expansions and Fertiglobe ammonia tie-up target long-term supply.

 

Abu Dhabi is seeking investors to help build hydrogen-export facilities, as Middle Eastern oil producers plan to adopt cleaner energy solutions, sources told Bloomberg.

Abu Dhabi National Oil Company (ADNOC) is holding talks with energy companies for them to purchase equity stakes in the hydrogen projects, the sources referred, as Germany's hydrogen strategy signals rising import demand.

ADNOC, which already produces hydrogen for its refineries, also aims to enter into long-term supply contracts, as Canada-Germany clean energy cooperation illustrates growing cross-border demand, before making any progress with these investments.

Amid a global push to reduce greenhouse-gas emissions, the state-owned oil companies in the Gulf region seek to turn their expertise in exporting liquid fuel into shipping hydrogen or ammonia across the world for clean and universal electricity needs, transport, and industrial use.

Most of the ADNOC exports are expected to be blue hydrogen, created by converting natural gas and capturing the carbon dioxide by-product that can enable using CO2 to generate electricity approaches, according to Bloomberg.

The sources said that the Abu Dhabi-based company will raise its production of hydrogen by expanding an oil-processing plant and the Borouge petrochemical facility at the Ruwais industrial hub, supporting a sustainable electric planet vision, as the extra hydrogen will be used for an ammonia facility planned with Fertiglobe.

Abu Dhabi also plans to develop green hydrogen, similar to clean hydrogen in Canada initiatives, which is generated from renewable energy such as solar power.

Noteworthy to mention, in May 2021, ADNOC announced that it will construct a world-scale blue ammonia production facility in Ruwais in Abu Dhabi to contribute to the UAE's efforts to create local and international hydrogen value chains.

Germany should stop lecturing France on nuclear power, says Eon boss

EU Nuclear Power Dispute strains electricity market reform as Germany resists state aid for French reactors, while Eon urges cooperation to meet the energy transition, low-carbon goals, renewables integration, and cross-border power trade.

 

Key Points

A policy standoff between Germany and France over nuclear energy's role, state aid, and electricity market reforms.

✅ Germany opposes state aid for existing French nuclear plants.

✅ Eon CEO urges compromise to advance market reform and decarbonization.

✅ Cross-border trade shows reliance on French nuclear amid renewables push.

 

Germany should stop trying to impose its views on nuclear power on the rest of the EU, the head of one of Europe’s largest utilities has warned, as he stressed its importance in the region’s clean energy transition.

Leonhard Birnbaum, chief executive of German energy provider Eon, said Berlin should accept differences of opinion as he signalled his desire for a compromise with France to break a deadlock amid a nuclear power dispute over energy reforms.

Germany this year shut down its final three nuclear power plants as it followed through on a long-held promise to drop the use of the energy source, effectively turning its back on nuclear for now, while France has made it a priority to modernise its nuclear power plants.

The differences are delaying reforms to the region’s electricity market and legislation designed to meet greenhouse gas emissions targets.

One sticking point is Germany’s refusal to back French moves to allow governments to provide state aid to existing power plants, which could enable Paris to support the French nuclear fleet.

The Eon chief, whose company has 48mn customers across Europe, said it would be “better for everyone” if the two countries could approach the dispute with the mindset that “everyone does their part”, even as Germany has at times weighed a U-turn on the nuclear phaseout in recent debates.

“Neither the French will be able to persuade us to use nuclear power, nor we will be able to persuade them not to. That’s why I think we should take a different approach to the discussion,” he added.

Birnbaum said Germany “would do well to be a bit cautious about trying to impose our way on everyone else”. This approach was unlikely to be “crowned with success”.

“The better solution will not come from opposing each other, but from working together.”

Birnbaum made the comments at a press conference announcing Eon’s second-quarter results.

The company raised its profit outlook, predicting adjusted net income of €2.7bn to €2.9bn, and promised to reduce bills for customers as it hailed “diminishing headwinds” following the energy crisis caused by the war in Ukraine.

Birnbaum, whose company owned one of the three German nuclear plants shut down this year, pointed out that French nuclear energy was helping the conversion to a system of renewable energy in Germany at a time when Europe is losing nuclear power just when it needs energy.

This was a reference to Europe’s shared power market that allows countries to buy and sell electricity from one another. 

Germany has been a net importer of French electricity since shutting down its own nuclear plants, which last month prompted the French energy minister Agnès Pannier-Runacher to accuse Berlin of hypocrisy. 

“It’s a contradiction to massively import French nuclear energy while rejecting every piece of EU legislation that recognises the value of nuclear as a low-carbon energy source,” Pannier-Runacher told the German business daily Handelsblatt.

She also criticised Berlin’s drive to use new gas-fired power plants as a “bridge” to its target of being carbon neutral by 2045, even as some German officials contend that nuclear won’t solve the gas issue in the near term, arguing that it created a “credibility problem” for Germany: “Gas is a fossil fuel.”

Berlin officials responded by pointing out that Germany was a net exporter of electricity to France over the winter when its nuclear power stations were struggling to produce because of maintenance problems. 

They added that the country only imported French power because it was cheaper, not because their country was suffering shortages.

Berlin argues that renewable energy is cleaner and safer than nuclear, despite renewable rollout challenges linked to cheap Russian gas and grid expansion, and accuses France of seeking to protect the interests of its nuclear industry.

In Paris, officials see Germany’s resistance to nuclear energy as wrong-headed given the need to fight climate change effectively, and worry it is an attempt to undercut a key aspect of French industrial competitiveness.

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.

Tariffs on Chinese Electric Vehicles

Canada EV Tariffs weigh protectionism, import duties, and trade policy against affordable electric vehicles, climate goals, and consumer costs, balancing domestic manufacturing, critical minerals, battery supply chains, and China relations amid US-EU actions.

 

Key Points

Canada EV Tariffs are proposed duties on Chinese EV imports to protect jobs vs. prices, climate goals, and trade risks.

✅ Shield domestic automakers; counter subsidies

✅ Raise EV prices; slow adoption, climate targets

✅ Spark China retaliation; hit exports, supply chains

 

Canada, a rising star in critical EV battery minerals, finds itself at a crossroads. The question: should they follow the US and EU and impose tariffs on Chinese electric vehicles (EVs), after the U.S. 100% tariff on Chinese EVs set a precedent?

The Allure of Protectionism

Proponents see tariffs as a shield for Canada's auto industry, supported by recent EV assembly deals that put Canada in the race, a vital job creator. They argue that cheaper Chinese EVs, potentially boosted by government subsidies, threaten Canadian manufacturers. Tariffs, they believe, would level the playing field.

Consumer Concerns and Environmental Impact

Opponents fear tariffs will translate to higher prices, deterring Canadians from buying EVs, especially amid EV shortages and wait times already affecting the market. This could slow down Canada's transition to cleaner transportation, crucial for meeting climate goals. A slower EV adoption could also impact Canada's potential as an EV leader.

The Looming Trade War Shadow

Tariffs risk escalating tensions with China, Canada's second-largest trading partner. China might retaliate with tariffs on Canadian exports, jeopardizing sectors like oil and lumber. This could harm the Canadian economy and disrupt critical mineral and battery development, areas where Canada is strategically positioned, even as opportunities to capitalize on the U.S. EV pivot continue to emerge across North America.

Navigating a Charged Path

The Canadian government faces a complex decision. Protecting domestic jobs is important, but so is keeping EVs affordable for a greener future and advancing EV sales regulations that shape the market. Canada must carefully consider the potential benefits of tariffs against the risks of higher consumer costs and a potential trade war.

This path forward could involve exploring alternative solutions. Canada could invest in its domestic EV industry, providing incentives for both consumers and manufacturers. Additionally, collaborating with other countries, including Canada-U.S. collaboration as companies turn to EVs, to address China's alleged unfair trade practices might be a more strategic approach.

Canada's decision on EV tariffs will have far-reaching consequences. Striking a balance between protecting its domestic industry and fostering a robust, environmentally friendly transportation sector, and meeting ambitious EV goals set by policymakers, is crucial. Only time will tell which path Canada chooses, but the stakes are high, impacting not just jobs, but also the environment and Canada's position in the global EV race.
