The European Climate, Infrastructure and Environment Executive Agency (CINEA) has signed grant agreements with seven solar projects across Finland with a combined capacity of 212.99 MW. A total €27.5 million is being invested across the projects through the EU renewable energy financing mechanism, following successful bids in the EU’s first cross-border solar tender held last […]

As technologists search for approaches to reduce our global carbon footprint and stave off the worst ravages of climate change, they are turning to an old friend—hydrogen. The potential of hydrogen fuel cells for generating power is enormous although not without issues. Published in the International Journal of Sustainable Aviation, a team from the UK and Romania […]

The White House on Tuesday will announce steps to modernize a major roadblock to the clean energy transformation: America’s aging electrical infrastructure. The new initiative between the feds and 21 states aims to make faster fixes and improvements to the grid, committing to build a bigger and more modern grid as part of a larger […]

A new heat-to-energy converter has reached a record efficiency of 44% – the average steam turbine manages about 35%, for comparison. This thermophotovoltaic cell is a major step on the way to sustainable, grid-scale renewable energy storage. With renewable energy prices dropping fast, the barrier now is their intermittency – the first point any renewable […]

“Megasolar opposed!! Don’t make a fool of us. Residents are angry,” screams one handwritten sign, the word “opposed” emphasized in red. “Absolutely against megasolar construction!” yells another. Signs like these dot the otherwise idyllic agricultural landscape in the city of Gojo, Nara Prefecture. Since January this year, when Nara Gov. Makoto Yamashita announced plans to […]

The Florida Office of Energy is planning to repeal goals for utilities statewide to transition to cleaner energy, including that 100% of the state’s energy come from renewable sources by 2050. The proposal to roll back the goals was crafted by the director of the Office of Energy, Brooks Rumenik, and has been approved by […]

Closing in on the theoretical maximum efficiency, devices for turning heat into electricity are edging closer to being practical for use on the grid, according to University of Michigan research. Heat batteries could store intermittent renewable energy during peak production hours, relying on a thermal version of solar cells to convert it into electricity later. […]

Why is squeezing out the gas so important? Electricity produced by gas peakers is the most expensive in the Australian grid. All electricity providers can then match that price even if they are producing electricity from free wind or sunshine. Batteries can store Australia’s massive oversupply of electricity produced during the day from abundant sunshine, […]

It doesn’t take a lot of energy to dig up coal or pump oil from the ground. In contrast, most renewable sources of energy involve obtaining and refining resources, sophisticated manufacturing, and installation. So, at first glance, when it comes to the energy used to get more energy—the energy return on investment—fossil fuels seem like […]
