German officials launched what they say is the world's first fleet of hydrogen-powered passenger trains Wednesday, replacing 15 diesel trains that previously operated on nonelectrified tracks in the state of Lower Saxony.

For about half an hour on Friday, the national energy market caught a glimpse of what a renewables-powered future might look like.

The rush to build wind farms to combat climate change is colliding with preservation of one of the U.S. West’s most spectacular predators — the golden eagle — as the species teeters on the edge of decline.

Covering parking lots makes both renewable energy and a more pleasant parking experience.

The US is a latecomer to offshore wind development, but President Biden has set big goals for expanding it. The Gulf of Mexico has good conditions and a large offshore energy industry.

The world’s best solar power schemes now offer the “cheapest…electricity in history” with the technology cheaper than coal and gas in most major countries. That is according to the International Energy Agency’s World Energy Outlook 2020. The 464-page outlook, published today by the IEA, also outlines the “extraordinarily turbulent” impact of coronavirus and the “highly uncertain” future of global energy use over the next two decades.

The Inflation Reduction Act is expected to cut roughly a billion tons of greenhouse gas emissions a year by 2030, save thousands of lives a year, and prompt a transformation of the U.S. energy and transportation landscape.

Only a relatively small fraction of gas actually, you know, moves your car around. The rest is wasted.

If we could harness fusion to generate electricity, it would be one of the most efficient and least polluting sources of energy possible.

Taxpayers spent $15 million on research to build a breakthrough battery. Then the U.S. government gave it to China.

After a moment when hopes dimmed that the United States could become an international leader on climate change, legislation that Congress is poised to approve could rejuvenate the country’s reputation and bolster its efforts to push other nations to reduce greenhouse gas emissions more quickly.

With energy and fuel costs at an all-time high, the world is seeking cost-effective solutions for moving away from oil and gas for energy needs. Luckily, a new study by Stanford University says that it might not be as difficult as we think to move toward renewable energy sources.

To accommodate the West Virginia senator, Democratic leadership agreed to legislation streamlining permits for the often-stalled Mountain Valley Pipeline and removing jurisdiction from a court that keeps ruling against the project.

The Biden administration projects the program could spur the development of 134 gigawatts of new solar power capacity nationwide.

The state's last coal-fired power plant will close down in September.

The West Virginia Democrat, a holdout on his party’s domestic agenda, said the package would reduce inflation, a concern he had cited in rejecting it just weeks ago.

A secondary school and a residents’ association have teamed up with Barcelona city council to create a solar energy community with the capacity to grow – rooftop by rooftop – across large areas of the city. The solar panels on the roof of Quatre Cantons secondary school in the former industrial district of Poblenou supply power to the school and 30 households in the surrounding area.

More has been invested in nuclear fusion in the last 12 months than over the past decade, according to new industry figures. The clean energy solution has attracted about $2.8bn (£2.5bn) in investment globally over the past year, compared with $1.9bn (£1.6bn) in total over the past decade.The solution produces clean energy by fusing together atomic nuclei. It is the reaction which powers the Sun and in turn fuels life on Earth.

Nearly 40GW of solar PV will be rolled out across Europe by the end of the year, according to SolarPower Europe (SPE), as the continent scrambles to deploy renewables and wean itself off Russian gas. The expectation-beating figure of more than 39GW of solar PV is a significant jump on last year’s figure of 27GW, itself a decade-long installation record.

The idea of storing heat in sand to warm homes through winter may, on the face of it, seem too simple to work. Drop a load of cheap builder's sand in an insulated silo, heat the sand with renewable electricity, and then tap the stored thermal energy for months on end.
