In February US company LanzaJet, which produces sustainable aviation fuel (SAF) from ethanol, announced that it intended to build a second, larger plant on US soil. The Inflation Reduction Act (IRA) was a “big influence”, says Jimmy Samartzis, its chief executive. The second plant would add to its facility in Soperton, Georgia – the world’s […]

Gold’s scorching run to an all-time high may seem easy to explain from a distance, given the fractious geopolitical climate and murky outlook for the global economy. The precious metal is famously seen as a “safe haven,” and the general view is that bullion prices should rise when interest rates fall — which many investors […]

The final coal-fired power plants in New England are slated to shutter in the coming years, making it the second region to phase out the energy source that powered the U.S. economy for decades. In an announcement late last month, New Hampshire-based power provider Granite Shore Power said it had reached an agreement with federal […]

As the moon passes in front of the sun on April 8, its shadow will knock down solar power production in a sweeping band across the United States from Texas to Maine, home to more than 31 million people. The United States currently has more than 139 gigawatts of solar electricity generation capacity. That’s more […]

Researchers at the US Department of Energy’s National Renewable Energy Laboratory (NREL) have developed a prototype for a multi-day energy storage system using heated sand, setting the stage for a pilot demonstration project. The sand used in the thermal energy storage (TES) system could be heated to the range of 1,100 C using low-cost renewable […]

When you live far from the sprawling fields befitting utility-scale solar and wind farms, it’s easy to feel like clean energy isn’t coming online fast enough. But renewables have grown at a staggering rate since 2014 and now account for 22 percent of the nation’s electricity. Solar alone has grown an impressive eightfold in 10 […]

The U.S. Department of Energy is investing $60 million to demonstrate the efficacy and scalability of enhanced geothermal systems to help tap into the heat trapped underground, which can be used as clean, renewable energy. The agency selected three projects to receive the funds — Chevron New Energies, Fervo Energy, and Mazama Energy. Chevron’s pilot […]

Solar cars exist. The best place to see them is the World Solar Challenge, a race that’s held every two years in Australia. Competitors have to drive about 1,870 miles (3,000 kilometers), from Darwin on the country’s north coast to Adelaide on its south coast, using only energy from the Sun. Many cars that compete in […]

Money to address Louisiana’s land loss crisis will soon be in far shorter supply as oil spill money runs dry. But part of the solution may be arriving with the winds. One state representative is proposing a constitutional amendment that would dedicate future revenue from offshore wind and other alternative energy to Louisiana’s coastal fund. […]

Despite feigning interest, Big Oil still appears to oppose the global green transition and could well stand in its way. As Saudi’s state oil company leader condemns the green transition and calls for long-term oil production, other major industry players are voicing their scepticism around renewable energy and clean tech. Despite large investments into green […]
