As a Democratic congressman from Oklahoma, Glenn English had a reputation as a fiscal conservative. As the head of a group of nonprofit rural electric utility cooperatives that rely heavily on coal, heÂ’s fighting hard to convince Congress to open up its wallet.

Massive new federal spending is needed, he says, to ensure that there is enough electricity to meet national demand in a way that doesnÂ’t exacerbate global warming.

For English and the members of the National Rural Electric Cooperative Association (NRECA), a powerful lobbying group that has broad grassroots reach and a deep-pocketed political action committee, one priority is a $12 billion per-year spending effort to help low-income households make their homes more energy-efficient.

“It’s a big number” that will be difficult to win given Democratic “pay as you go” budget rules, English acknowledged.

“In a tight budget, that’s always the question: What’s our priority?”

The lobbying effort by NRECA is one example of how groups wary of congressional efforts to curb global warming are trying to redirect the momentum to pay for expensive new federal spending programs. If the projects are successful, they could take some pressure off coal users to pay for their own emissions cuts in the near term.

English said the energy efficiency effort would help keep consumer electricity bills reasonable.

The effort to curb greenhouse gas emissions is routinely equated to the development of an atomic bomb or the campaign to fight World War II. Curbing global warming is so expansive a challenge that the federal government will have to take the lead role.

In another example, mining companies, labor groups and for-profit electric utilities are joining NRECA in lobbying Congress to create a fund that would spend around $2 billion a year to pay for a technology to capture carbon dioxide emissions before they reach the atmosphere. The gas would instead be injected back into the earth, where it would sit under an impermeable layer of rock, hopefully forever.

The government has averaged around $100 million a year on spending to develop the technology, but it remains prohibitively expensive. The $2 billion figure comes from an estimate in a study conducted by the Massachusetts Institute of Technology. Total spending would approach $20 billion.

In a March letter to Congress, the National Mining Association and United Mine Workers of America complained that “inadequate incentives exist to spur the development and early deployment of CCS technologies in the power generation sector. And the lack of a reliable, substantial and sustained source of funding from the federal government, in partnership with industry, exacerbates the problem.”

“If this is truly one of the greatest technological challenges facing mankind, then what better time to mobilize the assistance of the federal government in partnership with the private sector?” said Kraig Naasz, the president and CEO of the National Mining Association.

“If climate change is inevitable, we are losing precious, precious time in developing this technology.”

Other groups like the Center for American Progress have called for new spending on carbon sequestration technology. Environmental groups are supportive too.

But some worry that the coal users and producers are lobbying for additional spending as a climate cure-all that negates the need for actual emissions caps such as those called for in the climate bill written by Sens. Joe Lieberman (I-Conn.) and John Warner (R-Va.) that will be on the Senate floor next month.

“The question is, where is the money going to come from with appropriations so tight?” said Jeremy Symons of the National Wildlife Federation. “We shouldn’t pretend that magic money will appear for bold new energy directions without the essential ingredient of a cap-and-trade program.”

Climate bills like Warner-Lieberman create an auction of emissions allowances that will provide money to pay for carbon sequestration and other technology efforts to help companies meet their emissions caps, Symons noted.

Plus it creates a market-wide incentive to shift away from conventional coal plants, he said.

That will be a big shift for NRECA members; more than 80 percent of the power co-ops use comes from coal. By reducing emissions through energy efficiency improvements, the burden for utilities to reduce their own emissions may be reduced or at least delayed.

Instead of a broad cap-and-trade bill, Congress is likely to continue this year to play around the edges by extending tax incentives that encourage the development of renewable power, like solar and wind, and support energy efficiency programs.

English said that tax incentives arenÂ’t enough for low-income residents to replace leaky windows or old appliances that eat up electricity. A $500 per low-income household credit is needed to ensure the improvements are made.

That amounts to about $12 billion a year for five years.

This week, the NRECA is holding its annual convention where 3,000 co-op members descend on Washington to press their case in person to lawmakers.

Co-ops produce and distribute electricity to only around 11 percent of the population, but their customers are located in around 75 percent of the nationÂ’s landmass. That gives them extensive political reach.

For the members who don’t have an electric co-op in their districts, NRECA sponsors an “adopt a congressman” campaign to try to ensure they are contacted nevertheless.

NRECA, which grew out of New Deal efforts to electrify rural America, has started a new campaign to educate members of Congress and the public about the difficulty of meeting growing demand for electricity without worsening global warming trends. The effort has already generated 100,000 e-mails to lawmakers.

In addition to new spending programs, NRECA also has a number of policy changes for which it is lobbying this week.

The group has created a new renewable energy cooperative to help pay for renewable energy generation projects.

English said the effort would principally concentrate on wind energy projects in the Great Plains. But there arenÂ’t enough power lines to move electricity to the urban areas where it is needed, English said.

NRECA wants the federal government to take more control over where power lines are sited, to supercede local “not-in-my-backyard” laws that are blocking what it sees as a greater national good.

The Energy Department estimates energy demand will increase 17 percent between 2006 and 2020, which would require an additional 118,000 megawatts of power.

“In the next 10 years it will be extremely difficult to have enough electric power to meet the nation’s needs and have electric bills remain affordable. We need the government to partner with us to help avoid what we think is a very real possibility of blackouts and brownouts,” English said.

OPG, TVA Partner on New Nuclear Technology Development

OPG-TVA SMR Partnership advances advanced nuclear technology and small modular reactors for 24/7 carbon-free baseload power, enabling net-zero goals, cross-border licensing, and deployment within a North American clean energy hub.

 

Key Points

A cross-border effort by OPG and TVA to develop, license, and deploy SMRs for reliable, carbon-free baseload power.

✅ Coordinates design, licensing, construction, and operations

✅ Supports 24/7 baseload, net-zero targets, and energy security

✅ Leverages Darlington and Clinch River early site permits

 

Two of North America's leading nuclear utilities unveiled a pioneering partnership to develop advanced nuclear technology as an integral part of a clean energy future and creating a North American energy hub. Ontario Power Generation, whose OPG's SMR commitment is well established, and the Tennessee Valley Authority will jointly work to help develop small modular reactors as an effective long-term source of 24/7 carbon-free energy in both Canada and the U.S.

The agreement allows the companies to coordinate their explorations into the design, licensing, construction and operation of small modular reactors.

"As leaders in our industry and nations, OPG and TVA share a common goal to decarbonize energy generation while maintaining reliability and low-cost service, which our customers expect and deserve," said Jeff Lyash, TVA President and CEO. "Advanced nuclear technology will not only help us meet our net-zero carbon targets but will also advance North American energy security."

"Nuclear energy has long been key to Ontario's clean electricity grid, and is a crucial part of our net-zero future," said Ken Hartwick, OPG President and CEO. "Working together, OPG and TVA will find efficiencies and share best practices for the long-term supply of the economical, carbon-free, reliable electricity our jurisdictions need, supported by ongoing Pickering life extensions across Ontario's fleet."

OPG and TVA have similar histories and missions. Both are based on public power models that developed from renewable hydroelectric generation before adding nuclear to their generation mixes. Today, nuclear generation accounts for significant portions of their carbon-free energy portfolios, with Ontario advancing the Pickering B refurbishment to sustain capacity.

Both are also actively exploring SMR technologies. OPG is moving forward with plans to deploy an SMR at its Darlington nuclear facility in Clarington, ON, as part of broader Darlington SMR plans now underway. The Darlington site is the only location in Canada licensed for new nuclear with a completed and accepted Environmental Assessment. TVA currently holds the only Nuclear Regulatory Commission Early Site Permit in the U.S. for small modular reactor deployment at its Clinch River site near Oak Ridge, TN.

No exchange of funding is involved. However, the collaboration agreement will help OPG and TVA reduce the financial risk that comes from development of innovative technology, as well as future deployment costs.

"TVA has the most recent experience completing a new nuclear plant in North America at Watts Bar and that knowledge is invaluable to us as we work toward the first SMR groundbreaking at Darlington," said Hartwick. "Likewise, because we are a little further along in our construction timing, TVA will gain the advantage of our experience before they start work at Clinch River."

"It's a win-win agreement that benefits all of those served by both OPG and TVA, as well as our nations," said Lyash. "Moving this technology forward is not only a significant step in advancing a clean energy future and Canada's climate goals, but also in creating a North American energy hub."

"With the demand for clean electricity on the rise around the world, Ontario's momentum is growing. The world is watching Ontario as we advance our work to fully unleash our nuclear advantage, alongside a premiers' SMR initiative that underscores provincial collaboration. I congratulate OPG and TVA – two great industry leaders – for working together to deploy SMRs and showcase and apply Canada's nuclear expertise that will deliver economic, health and environmental benefits for all of us to enjoy," said Todd Smith, Ontario Minister of Energy.

"The changing climate is a global crisis that requires global solutions. The partnership between the Tennessee Valley Authority and Ontario Power Generation to develop and deploy advanced nuclear technology is exactly the kind of innovative collaboration that is needed to quickly bring the next generation of nuclear carbon-free generation to market. I applaud the leadership that both companies are demonstrating to further strengthen our cross-border relationships," said Maria Korsnick, President and CEO, Nuclear Energy Institute.

Three New Solar Electricity Facilities in Alberta Contracted At Lower Cost than Natural Gas

Alberta Solar Energy Contracts secure low-cost photovoltaic PPAs for government operations, delivering renewable electricity at 4.8 cents/kWh, beating natural gas LCOE, enhancing summer grid efficiency across Hays, Tilley, and Jenner with Canadian Solar.

 

Key Points

Low-cost PV power agreements meeting 55% of Alberta government electricity demand via new Canadian Solar facilities.

✅ Price: 4.8 cents/kWh CAD, under gas-fired generation LCOE.

✅ Sites: Hays, Tilley, Jenner; 50% equity with Conklin Métis Local #193.

✅ Supplies 55% of provincial government electricity demand.

 

Three new solar electricity facilities to be built in south eastern Alberta (Canada) amid Alberta's solar growth have been selected through a competitive process to supply the Government of Alberta with 55 per cent of their annual electricity needs. The facilities will be built near Hays, Tilley, and Jenner, by Canadian Solar with Conklin Métis Local #193 as 50-percent equity owners.

The Government of Alberta's operations have been powered 100 per cent with wind power since 2007. Upon the expiration of some of these contracts, they have been renewed to switch from wind to solar energy. The average contract pricing will be $0.048 per kilowatt hour (3.6 cents/kWh USD), which is less than the average historical wholesale power pool price paid to natural gas-fired electricity in the province in years 2008 - 2018.

"The conversation about solar energy has long been fixated on its price competitiveness with fossil fuels," said John Gorman, CanSIA President & CEO. "Today's announcement demonstrates that low cost solar energy has arrived as a mainstream option in Alberta, even as demand for solar lags in Canada according to federal assessments. The conversation should next focus on how to optimize an all-of-the-above strategy for developing the province's renewable and non-renewable resources."

"This price discovery is monumental for the solar industry in Canada" said Patrick Bateman, CanSIA Director of Policy & Market Development. "At less than five cents per kilowatt hour, this solar electricity has a cost that is less than that of natural gas. Achieving Alberta's legislated 30 per cent by 2030 renewable electricity target just became a whole lot cheaper!".

 

Quick Facts:

  • The contract price of 4.8 cents/kWh CAD to be paid by Alberta Infrastructure for this solar electricity represents a lower Levelized Cost of Electricity (LCOE) than the average annual wholesale price paid by the power pool to combined-cycle and single-cycle natural gas-fired electricity generation which was 7.1 cents/kWh and 11.2 cents/kWh respectively from 2008 - 2018.
  • Alberta receives more hours of sunshine than Miami, Florida in the summer months. Alberta's electricity supply is most strained in summer, highlighting challenges for solar expansion when high temperatures increase the resistance of the distribution and transmission systems, and reduce the efficiency of cooling thermal power plants. For this reason, solar facilities sited near to electricity demand improves overall grid efficiency. Supply shortages are atypical in Alberta in winter when solar energy is least available. When they do occur, imports are increased and large loads are decreased.
  • In 2018, Alberta's solar electricity generation exceeded 50 MW. While representing much less than 1% of the province's electricity supply today, the Canadian Solar Industries Association (CanSIA) forecasts that solar energy could supply as much as 3 per cent of the province's electricity by 2030, supporting renewable energy job growth across Alberta. A recent supply chain study of the solar electricity sector in Alberta by Solas Energy Consulting Inc. found a potential of $4.1 billion in market value and a labour force rising to 10,000 in 2030.

European Power Hits Records as Plants Start to Buckle in Heat

European Power Crisis intensifies as record electricity prices, nuclear output cuts, gas supply strain, heatwave drought, and Rhine shipping bottlenecks hit Germany, France, and Switzerland, tightening winter storage and driving long-term contracts higher.

 

Key Points

A surge in European power prices from heatwaves, nuclear curbs, Rhine coal limits, and reduced Russian gas supply.

✅ Record year-ahead prices in Germany and France

✅ Nuclear output curbed by warm river cooling limits

✅ Rhine low water disrupts coal logistics and generation

 

Benchmark power prices in Europe hit fresh records Friday as utilities are increasingly reducing electricity output in western Europe because of the hot weather. 

Next-year contracts in Germany and France, Europe’s biggest economies rose to new highs after Switzerland’s Axpo Holding AG announced curbs at one of its nuclear plants. Electricite de France SA is also reducing nuclear output because of high river temperatures and cooling water restrictions, while Uniper SE in Germany is struggling to get enough coal up the river Rhine. 

Europe is suffering its worst energy crunch in decades, and losing nuclear power is compounding the strain as gas cuts made by Russia in retaliation for sanctions drive a surge in prices. The extreme heat led to the driest July on record in France and is underscoring the impact that a warming climate is having on vital infrastructure.

Water levels on Germany’s Rhine have fallen so low that the river may effectively close soon, impacting supplies of coal to the plants next to it. The Rhone and Garonne in France and the Aare in Switzerland are all too warm to be used to cool nuclear plants effectively, forcing operators to limit energy output under environmental constraints. 

Northwest European weather forecast for the next two weeks:
relates to European Power Hits Records as Plants Start to Buckle in Heat
  
The German year-ahead contract gained as much as 2% to 413 euros a megawatt-hour on the European Energy Exchange AG. The French equivalent rose 1.9% to a record 535 euros. Long-term prices are coming under pressure because producing less power from nuclear and coal will increase the demand for natural gas, which is badly needed to fill storage sites ahead of the winter.  


France to Curb Nuclear Output as Europe’s Energy Crisis Worsens
Uniper SE said on Thursday that two of its coal-fired stations along the Rhine may need to curb output during the next few weeks as transporting coal along the Rhine becomes impossible. 

Plants on the river near Mannheim and Karlsruhe, operated by Grosskraftwerk Mannheim AG and EnBW AG, have previously struggled to source coal because of the shallow water, even as German renewables deliver more electricity than coal and nuclear at times. Both companies said generation hasn’t been affected yet. 

“The low tide is not currently affecting our generation of energy because our plants do not have the need for continuous fresh water,” a Steag GmbH spokesman said on Friday. “But the low tide level can make running plants and transporting coal more complicated than usual.”

The spokesman said though that there is slight reduction in output of about 10 to 15 megawatts, which would equate to a few percent, because of the hot temperatures. “This has been happening over some time now and is a problem for everyone because the plant system is not designed to withstand such hot temperatures,” he said.

"In our recent Climate Report, we shared a vision of a cleaner electricity future with an increasing focus on renewables and battery storage in addition to a diverse mix of zero-carbon nuclear, natural gas, hydro and energy efficiency programs.

"Achieving this clean energy vision will require all of us working together to develop a plan that is smart, equitable and ensures the reliability and affordability that will spur economic growth in the region. While we're disappointed that we're not able to move forward with ACP, we will continue exploring ways to help our customers and communities, particularly in eastern North Carolina where the need is great," said Good.

Already a clean-energy leader, Duke Energy has reduced its carbon emissions by 39% from 2005 and remains on track to cut its carbon emissions by at least 50% by 2030, as peers like Alliant's carbon-neutral plan demonstrate broader industry momentum toward decarbonization. The company also has an ambitious clean energy goal of reaching net-zero emissions from electricity generation by 2050. 

In September 2020, Duke Energy plans to file its Integrated Resource Plans (IRP) for the Carolinas after an extensive process of working with the state's leaders, policymakers, customers and other stakeholders. The IRPs will include multiple scenarios to support a path to a cleaner energy future in the Carolinas, reflecting key utility trends shaping resource planning.

Since 2010, Duke Energy has retired 51 coal units totaling more than 6,500 megawatts (MW) and plans to retire at least an additional 900 MW by the end of 2024. In 2019, the company proposed to shorten the book lives of another approximately 7,700 MW of coal capacity in North Carolina and Indiana.

Duke Energy will host an analyst call in early August 2020 to discuss second quarter 2020 financial results and other business and financial updates. The company will also host its inaugural Environmental, Social and Governance (ESG) investor day in October 2020.

Spent fuel removal at Fukushima nuclear plant delayed up to 5 years

Fukushima Daiichi decommissioning delay highlights TEPCO's revised timeline, spent fuel removal at Units 1 and 2, safety enclosures, decontamination, fuel debris extraction by robot arm, and contaminated water management under stricter radiation control.

 

Key Points

A government revised schedule pushing back spent fuel removal and decommissioning milestones at Fukushima Daiichi.

✅ TEPCO delays spent fuel removal at Units 1 and 2 for safety.

✅ Enclosures, decontamination, and robotics mitigate radioactive risk.

✅ Contaminated water cut target: 170 tons/day to 100 by 2025.

 

The Japanese government decided Friday to delay the removal of spent fuel from the Fukushima Daiichi nuclear power plant's Nos. 1 and 2 reactors by as much as five years, casting doubt on whether it can stick to its timeframe for dismantling the crippled complex.

The process of removing the spent fuel from the units' pools had previously been scheduled to begin in the year through March 2024.

In its latest decommissioning plan, the government said the plant's operator, Tokyo Electric Power Company Holdings Inc., will not begin the roughly two-year process (a timeline comparable to major reactor refurbishment programs seen worldwide) at the No. 1 unit at least until the year through March 2028 and may wait until the year through March 2029.

Work at the No. 2 unit is now slated to start between the year through March 2025 and the year through March 2027, it said.

The delay is necessary to take further safety precautions such as the construction of an enclosure around the No. 1 unit to prevent the spread of radioactive dust, and decontamination of the No. 2 unit, even as authorities have begun reopening previously off-limits towns nearby, the government said. It is the fourth time it has revised its schedule for removing the spent fuel rods.

"It's a very difficult process and it's hard to know what to expect. The most important thing is the safety of the workers and the surrounding area," industry minister Hiroshi Kajiyama told a press conference.

The government set a new goal of finishing the removal of the 4,741 spent fuel rods across all six of the plant's reactors by the year through March 2032, amid ongoing debates about the consequences of early nuclear plant closures elsewhere.

Plant operator TEPCO has started the process at the No. 3 unit and already finished at the No. 4 unit, which was off-line for regular maintenance at the time of the disaster. A schedule has yet to be set for the Nos. 5 and 6 reactors.

While the government maintained its overarching timeframe of finishing the decommissioning of the plant 30 to 40 years from the 2011 crisis triggered by a magnitude 9.0 earthquake and tsunami, there may be further delays, even as milestones at other nuclear projects are being reached worldwide.

The government said it will begin removing fuel debris from the three reactors that experienced core meltdowns in the year through March 2022, starting with the No. 2 unit as part of broader reactor decommissioning efforts.

The process, considered the most difficult part of the decommissioning plan, will involve using a robot arm, reflecting progress in advanced reactors technologies, to initially remove small amounts of debris, moving up to larger amounts.

The government also said it will aim to reduce the pace at which contaminated water at the plant increases. Water for cooling the melted cores, mixed with underground water, amounts to around 170 tons a day. That number will be brought down to 100 tons by 2025, it said.

The water is being treated to remove the most radioactive materials and stored in tanks on the plant's grounds, but already more than 1 million tons has been collected and space is expected to run out by the summer of 2022.

A robot is killing weeds by zapping them with electricity

Electric weed-zapping farm robots enable precision agriculture, using autonomous mapping, per-plant targeting, and robotics to reduce pesticides, improve soil health, boost biodiversity, and lower costs with data-driven, selective weeding and seed-planting workflows.

 

Key Points

Autonomous machines that map fields, electrocute weeds per plant, and plant seeds, cutting pesticides, inputs, and costs.

✅ Precision agriculture: per-plant targeting reduces pesticide use up to 95%.

✅ Autonomous mapping robot surveys 20 hectares per day for weed data.

✅ Electric weeding and seeding improve soil health, biodiversity, and ROI.

 

On a field in England, three robots have been given a mission: to find and zap weeds with electricity, as advances in digitizing the electrical system continue to modernize power infrastructure, before planting seeds in the cleared soil.

The robots — named Tom, Dick and Harry — were developed by Small Robot Company to rid land of unwanted weeds with minimal use of chemicals and heavy machinery, complementing emerging options like electric tractors that aim to cut on-farm emissions.
The startup has been working on its autonomous weed killers since 2017, and this April launched Tom, its first commercial robot which is now operational on three UK farms. The other robots are still in the prototype stage, undergoing testing.

Small Robot says robot Tom can scan 20 hectares (49 acres) a day, collecting data, with AI-driven analysis guiding Dick, a "crop-care" robot, to zap weeds. Then it's robot Harry's turn to plant seeds in the weed-free soil.

Using the full system, once it is up and running, farmers could reduce costs by 40% and chemical usage by up to 95%, the company says, and integration with virtual power plants could further optimize energy use on electrified farms.

According to the UN Food and Agriculture Organization six million metric tons of pesticides were traded globally in 2018, valued at $38 billion.

"Our system allows farmers to wean their depleted, damaged soils off a diet of chemicals," says Ben Scott-Robinson, Small Robot's co-founder and CEO.

Zapping weeds
Small Robot says it has raised over £7 million ($9.9 million). Scott-Robinson says the company hopes to launch its full system of robots by 2023, which will be offered as a service at a rate of around £400 ($568) per hectare. The monitoring robot is placed at a farm first and the weeding and planting robots delivered only when the data shows they're needed — a setup that ultimately relies on a resilient grid, where research into preventing ransomware attacks is increasingly relevant.

To develop the zapping technology, Small Robot partnered with another UK-based startup, RootWave, while innovations like electricity from snow highlight the breadth of emerging energy tech.

"It creates a current that goes through the roots of the plant through the soil and then back up, which completely destroys the weed," says Scott-Robinson. "We can go to each individual plant that is threatening the crop plants and take it out."

"It's not as fast as it would be if you went out to spray the entire field," he says. "But you have to bear in mind we only have to go into the parts of the field where the weeds are." Plants that are neutral or beneficial to the crops are left untouched.

Small Robot calls this "per plant farming" — a type of precise agriculture where every plant is accounted for and monitored.

A business case
For Kit Franklin, an agricultural engineering lecturer from Harper Adams University, efficiency remains a hurdle, even as utilities use AI to adapt to electricity demands that could support wider on-farm electrification.

"There is no doubt in my mind that the electrical system works," he tells CNN Business. "But you can cover hundreds of hectares a day with a large-scale sprayer ... If we want to go into this really precise weed killing system, we have to realize that there is an output reduction that is very hard to overcome."

But Franklin believes farmers will adopt the technology if they can see a business case.

"There's a realization that farming in an environmentally friendly way is also a way of farming in an efficient way," he says. "Using less inputs, where and when we need them, is going to save us money and it's going to be good for the environment and the perception of farmers."

As well as reducing the use of chemicals, Small Robot wants to improve soil quality and biodiversity.

"If you treat a living environment like an industrial process, then you are ignoring the complexity of it," Scott-Robinson says. "We have to change farming now, otherwise there won't be anything to farm."
