Wind turbines as a renewable energy source have problems of noise, visual clutter and land use, and one U.S. researcher says moving them offshore is a solution.

Offshore wind farms have been built, but only in shallow water near coasts, and one naval architect wants to go much farther out by placing turbines on floating platforms, a release from the American Institute of Physics said.

Dominique Roddier of Marine Innovation & Technology of Berkeley, Calif., has proposed a platform design dubbed "WindFloat" based on existing gas and oil platform designs.

Roddier and his and colleagues published a feasibility study of the design in the Journal of Renewable and Sustainable Energy, published by the AIP.

Testing of a small scale model in a wave tank showed the platform is stable enough to support a 5-megawatt wind turbine producing enough energy "to support a small town," Roddier said.

A full-size prototype being built in collaboration with electricity company Energia de Portugal "should be in the water by the end of 2012," Roddier says.

New Program Set to Fight for 'Electricity Future That Works for People and the Planet'

Energy Justice Program drives a renewables-based transition, challenging utility monopolies with legal action, promoting rooftop solar, distributed energy, public power, and climate justice to decarbonize the grid and protect communities and wildlife nationwide.

 

Key Points

A climate justice initiative advancing renewables, legal action, and public power to challenge utility monopolies.

✅ Challenges utility barriers to rooftop solar and distributed energy

✅ Advances state and federal policies for equitable, public power

✅ Uses litigation to curb fossil fuel dependence and protect communities

 

The Center for Biological Diversity on Monday rolled out a new program to push back against the nation's community- and wildlife-harming energy system that the climate advocacy group says is based on fossil fuels and a "centralized monopoly on power."

The goal of the new effort, the Energy Justice Program, is to help forge a path towards a just and renewables-based energy future informed by equitable regulation principles.

"Our broken energy system threatens our climate and our future," said Jean Su, the Energy Justice Program's new director, in a statement. "Utilities were given monopolies to ensure public access to electricity, but these dinosaur corporations are now hurting the public interest by blocking the clean energy transition, including via coal and nuclear subsidy schemes that profit off the fossil fuel era."

"In this era of climate catastrophe," she continued, "we have to stop these outdated monopolies and usher in a new electricity future that works for people and the planet."

To meet those goals, the new program will pursue a number of avenues, including using legal action to fight utilities' obstruction of clean energy efforts, helping communities advance local solar programs through energy freedom strategies in the South, and crafting energy policies on the state, federal, and international levels in step with commitments from major energy buyers to achieve a 90% carbon-free goal by 2030.

Some of that work is already underway. In June the Center filed a brief with a federal court in a bid to block Arizona power utility Salt River Project from slapping a 60-percent electricity rate hike on rooftop solar customers—amid federal efforts to reshape electricity pricing that critics say are being rushed—a move the group described (pdf) as an obstacle to achieving "the energy transition demanded by climate science."

The Center is among the groups in Energy Justice NC. The diverse coalition seeks to end the energy stranglehold in North Carolina held by Duke Energy, which continues to invest in fossil fuel projects even as it touts clean energy and grid investments in the region.

The time for a new energy system, says the Energy Justice Program, is now, as climate change impacts increasingly strain the grid.

"Amid this climate and extinction emergency," said Su, "the U.S. can't afford to stick with the same centralized, profit-driven electricity system that drove us here in the first place. We have to seize this once-in-a-generation opportunity to design a new system of accountable, equitable, truly public power."

B.C. Hydro adds more vehicle charging stations across southern B.C.

BC Hydro EV Charging Stations expand provincewide with DC fast chargers, 80% in 30 minutes at 35 c/kWh, easing range anxiety across Vancouver, Vancouver Island, Coquihalla Highway, East Kootenay, between Kamloops and Prince George.

 

Key Points

Public DC fast-charging network across B.C. enabling 80% charge in 30 minutes to cut EV range anxiety.

✅ 28 new stations added; 30 launched in 2016

✅ 35 c/kWh; about $3.50 per tank equivalent

✅ Coverage: Vancouver, Island, Coquihalla, East Kootenay

 

B.C. Hydro is expanding its network of electric vehicle charging stations.

The Crown utility says 28 new stations complete the second phase of its fast-charging network and are in addition to the 30 stations opened in 2016.

Thirteen of the stations are in Metro Vancouver, seven are on Vancouver Island, including one at the Pacific Rim Visitor Centre near Tofino, another is in Campbell River, and two have opened on the Coquihalla segment of B.C.'s Electric Highway at the Britton Creek rest area.

A further six stations are located throughout the East Kootenay and B.C. Hydro says the next phase of its program will connect drivers travelling between Kamloops and Prince George, while stations in Prince Rupert are also being planned.

BC Hydro has also opened a fast charging site in Lillooet, illustrating expansion into smaller communities.

Hydro spokeswoman Mora Scott says the stations can charge an electric vehicle to 80 per cent in just 30 minutes, at a cost of 35 cents per kilowatt hour.

Mora Scott says that translates to roughly $3.50 for the equivalent of a full tank of gas in the average four-cylinder car.

“The number of electric vehicles on B.C. roads is increasing, there’s currently around 9,000 across the province, and we actually expect that number to rise to 300,000 by 2030,” Scott says in a news release.

In partnership with municipalities, regional districts and several businesses, B.C. Hydro has been installing charging stations throughout the province since 2012 with support from the provincial and federal governments and programs such as EV charger rebates available to residents.

Scott says the utility wants to ensure the stations are placed where drivers need them so charging options are available provincewide.

“One big thing that we know drivers of electric vehicles worry about is the concept called range anxiety, that the stations aren’t going to be where they need them,” she says.

Several models of electric vehicle are now capable of travelling up to 500 kilometres on a single charge, says Scott.

BC Hydro president Chris O’Riley says the new charging sites will encourage electric vehicle drivers to explore B.C. this summer.

New rules give British households right to sell solar power back to energy firms

UK Smart Export Guarantee enables households to sell surplus solar energy to suppliers, with dynamic export tariffs, grid payments, and battery-friendly incentives, boosting local renewable generation, microgeneration uptake, and decarbonisation across Britain.

 

Key Points

UK Smart Export Guarantee pays homes for exporting surplus solar power to the grid via supplier tariffs.

✅ Suppliers must pay households for exported kWh.

✅ Dynamic tariffs incentivize daytime solar generation.

✅ Batteries boost self-consumption and grid flexibility.

 

Britain’s biggest energy companies will have to buy renewable energy from their own customers through community-generated green electricity models under new laws to be introduced this week.

Homeowners who install new rooftop solar panels from 1 January 2020 will be able to lower their bills as many seek to cut soaring bills by selling the energy they do not need to their supplier.

A record was set at noon on a Friday in May 2017, when solar energy supplied around a quarter of the UK’s electricity, and a recent award that adds 10 GW of renewables indicates further growth.

However, solar panel owners are not always at home on sunny days to reap the benefit. The new rules will allow them to make money if they generate electricity for the grid.

Some 800,000 householders with solar panels already benefit from payments under a previous scheme. However, the subsidies were controversially scrapped by the government in April, with similar reduced credits for solar owners seen in other regions, causing the number of new installations to fall by 94% in May from the month before.

Labour accused the government last week of “actively dismantling” the solar industry. The sector will still struggle this summer as the change does not come in for another seven months, so homeowners have no incentive to buy panels this year.

Chris Skidmore, the minister for energy and clean growth, said the government wanted to increase the number of small-scale generators without adding the cost of subsidies to energy bills. “The future of energy is local and the new smart export guarantee will ensure households that choose to become green energy generators will be guaranteed a payment for electricity supplied to the grid,” he said. The government also hopes to encourage homes with solar panels to install batteries to help manage excess solar power on networks.

Greg Jackson, the founder of Octopus Energy, said: “These smart export tariffs are game-changing when it comes to harnessing the power of citizens to tackle climate change”.

A few suppliers, including Octopus, already offer to buy solar power from their customers, often setting terms for how solar owners are paid that reflect market conditions.

“They mean homes and businesses can be paid for producing clean electricity just like traditional generators, replacing old dirty power stations and pumping more renewable energy into the grid. This will help bring down prices for everyone as we use cheaper power generated locally by our neighbours,” Jackson said.

Léonie Greene, a director at the Solar Trade Association, said it was “vital” that even “very small players” were paid a fair price. “We will be watching the market like a hawk to see if competitive offers come forward that properly value the power that smart solar homes can contribute to the decarbonising electricity grid,” she said.

USA: 3 Ways Fossil Energy Ensures U.S. Energy Security

DOE Office of Fossil Energy safeguards energy security via the Strategic Petroleum Reserve, domestic critical minerals from coal byproducts, and carbon capture to curb CO2, strengthening resiliency amid shocks and supporting U.S. manufacturing and defense.

 

Key Points

A DOE program advancing energy security through SPR stewardship, critical minerals R&D, and carbon capture.

✅ Manages the Strategic Petroleum Reserve for emergency crude supply

✅ Develops domestic critical minerals from coal and mining byproducts

✅ Deploys carbon capture, utilization, and storage to cut CO2

 

The global economy has just experienced a period of unique transformation because of COVID-19. The fact that remains constant in this new economic landscape is that our society relies on energy; it’s an integral part of our day-to-day lives, even as U.S. energy use has evolved over time. According to the U.S. Energy Information Administration, approximately 80 percent of energy consumption in the United States comes from fossil fuels, so having access to a secure and reliable supply of those energy resources is more important than ever for national energy security considerations today. Below are three examples that highlight how our work at the U.S. Department of Energy’s Office of Fossil Energy (FE) helps ensure the Nation’s energy security and resiliency.

(1) Open crude oil reserves to respond to crises

FE has overall program responsibility for carrying out the mission of the Strategic Petroleum Reserve (SPR), the world’s largest supply of emergency crude oil. These federally-owned stocks are stored in massive underground salt caverns along the coastline of the Gulf of Mexico. The SPR is a powerful tool U.S. leaders use to respond to a wide range of crises, including energy crisis impacts on electricity and fuels, involving crude oil disruption or demand loss.  When the COVID-19 pandemic hit, the oil markets crashed and crude oil demand dropped drastically across the world. U.S. oil producers turned to the SPR to store their oil while broader energy dominance constraints were becoming evident in practice. This helped alleviate the pressure on producers to shut in oil production and proved to be a critical asset for American energy and national security.

(2) Use the Nation’s abundant coal reserves to produce valuable materials

Critical materials, including rare earth elements, are a group of chemical elements and materials with unique properties that support manufacturing of most modern technologies. They are essential components for critical defense and homeland security applications, green energy technologies, hybrid and electric vehicles, and high-value electronics. While these materials are not rare, they are hard to separate and expensive to extract. The United States relies heavily on imports from China. To reduce U.S. dependence on foreign sources, FE has a research and development program aimed at producing a domestic supply of critical materials from the Nation’s abundant coal resources and associated byproducts from legacy and current mining operations. Many of the technologies being developed can also be used to separate critical minerals from other mining materials and byproducts. Tapping into these resources has the potential to create new industries and revitalize coal communities and the workforce in coal-producing regions.

(3) Decrease carbon emissions for a cleaner energy future

FE is committed to balancing the Nation’s energy use with the need to protect the environment, and has a comprehensive portfolio of technological solutions that help keep carbon dioxide (CO2) emissions out of the atmosphere. For example, amid high natural gas prices that reinforce the case for clean electricity, the Department has been investing in carbon capture, utilization, and storage technologies for over a decade. These technologies capture CO2 emissions from various sources, including coal-fired power plants and manufacturing plants, before they enter the atmosphere. Several of these cutting-edge technologies have been deployed at major demonstration sites, supported by clean energy funding that aims to benefit millions. Three of these projects—Petra Nova, Archer Daniels Midland, and Air Products & Chemicals—have captured and injected over 10.8 million metric tons of CO2. The success of these projects is paving the way toward a cleaner and more sustainable American energy future.

Ontario Breaks Ground on First Small Modular Nuclear Reactor

Ontario SMR BWRX-300 leads Canada in next-gen nuclear energy at Darlington, with GE Vernova and Hitachi, delivering clean, reliable power via modular design, passive safety, scalability, and lower costs for grid integration.

 

Key Points

Ontario SMR BWRX-300 is a 300 MW modular boiling water reactor at Darlington with passive safety and clean power.

✅ 300 MW BWR supplies power for about 300,000 homes

✅ Passive safety enables safe shutdown without external power

✅ Modular design reduces costs and speeds grid integration

 

Ontario has initiated the construction of Canada's first small modular nuclear reactor (SMR), supported by OPG's SMR commitment to deployment, marking a significant milestone in the province's energy strategy. This development positions Ontario at the forefront of next-generation nuclear technology within the G7 nations.

The project, known as the Darlington New Nuclear Project, is being led by Ontario Power Generation (OPG) in collaboration with GE Vernova and Hitachi Nuclear Energy, and through its OPG-TVA partnership on new nuclear technology development. The chosen design is the BWRX-300, a 300-megawatt boiling water reactor that is approximately one-tenth the size and complexity of traditional nuclear reactors. The first unit is expected to be operational by 2029, with plans for additional units to follow.

Each BWRX-300 reactor is projected to supply electricity to about 300,000 homes, contributing to Ontario's efforts, which include the decision to refurbish Pickering B for additional baseload capacity, to meet the anticipated 75% increase in electricity demand by 2050. The compact design of the SMR allows for easier integration into existing infrastructure, reducing the need for extensive new transmission lines.

The economic impact of the project is substantial. The construction of four such reactors is expected to create up to 18,000 jobs and contribute approximately $38.5 billion CAD to the Canadian economy, reflecting the economic benefits of nuclear projects over 65 years. The modular nature of SMRs also allows for scalability, with each additional unit potentially reducing costs through economies of scale.

Safety is a paramount consideration in the design of the BWRX-300. The reactor employs passive safety features, meaning it can safely shut down without the need for external power or operator intervention. This design enhances the reactor's resilience to potential emergencies, aligning with stringent regulatory standards.

Ontario's commitment to nuclear energy is further demonstrated by its plans for four SMRs at the Darlington site. This initiative reflects a broader strategy to diversify the province's energy mix, incorporating clean and reliable power sources to complement renewable energy efforts.

While the development of SMRs in Ontario is a significant step forward, it also aligns with the Canadian nuclear initiative positioning Canada as a leader in the global nuclear energy landscape. The successful implementation of the BWRX-300 could serve as a model for other nations exploring advanced nuclear technologies.

Ontario's groundbreaking work on small modular nuclear reactors represents a forward-thinking approach to energy generation. By embracing innovative technologies, the province is not only addressing future energy demands but also, through the Pickering NGS life extension, contributing to the global transition towards sustainable and secure energy solutions.
