The pilot is located off the coast of Haiyang, a city in Read more about The world’s first offshore floating wind-solar pilot just came online in China[…]

Back in 2013, Techdirt wrote about “the monster lurking inside free trade agreements”. Formally, the monster is known as Investor-State Dispute Settlement (ISDS), but here on Techdirt we call it “corporate sovereignty“, because that is what it is: a system of secret courts that effectively places companies above a government, by allowing them to sue Read more about Finally: Countries Start To Rebel Against Corporate Sovereignty, But Ten Years Too Late[…]

The project, and others like it, could help unlock America’s clean energy future. Perhaps a decade from now, if all goes smoothly, large underground pipes will connect this Read more about A California project would store solar energy to use when the sun goes down in water batteries[…]

1. Fossil Fuels View the full-size infographic While the U.S. is a dominant player in both oil and natural gas production, China holds the top spot as the world’s largest fossil fuel producer, largely because of its significant production and consumption of coal. Over the last decade, China has used more coal than the rest Read more about Charted: 40 Years of Global Energy Production, by Country[…]

[…] To avoid taking water from an already strained local supply, a team led by Gang Kevin Li, senior lecturer at the University of Melbourne, Australia, has built a system which extracts water from airborne vapor using a hygroscopic electrolyte, in this case sulfuric acid. The approach then uses solar-generated electricity to split the water Read more about Hydrogen could be harvested from thin air in the desert[…]

A nuclear fusion reaction has lasted for 30 seconds at temperatures in excess of 100 million°C. While the duration and temperature alone aren’t records, the simultaneous achievement of heat and stability brings us a step closer to a viable fusion reactor – as long as the technique used can be scaled up. Most scientists agree Read more about Korean nuclear fusion tokamak reactor achieves 100 million°C for 30 seconds[…]

Hydrogen fuel promises to be a clean and abundant source of energy in the future – as long as scientists can figure out ways to produce it practically and cheaply, and without fossil fuels. A new study provides us with another promising step in that direction, provided you can make use of existing supplies of Read more about Scientists Find a Simple Way to Produce Hydrogen From Water at Room Temperature[…]

A major breakthrough in nuclear fusion has been confirmed a year after it was achieved at a laboratory in California. Researchers at Lawrence Livermore National Laboratory’s (LLNL’s) National Ignition Facility (NIF) recorded the first case of ignition on August 8, 2021, the results of which have now been published in three peer-reviewed papers. Nuclear fusion Read more about Nuclear Fusion Breakthrough Confirmed: California Team Achieved Ignition[…]

Virtually all wind turbines, which produce more than 5 percent of the world’s electricity, are controlled as if they were individual, free-standing units. In fact, the vast majority are part of larger wind farm installations involving dozens or even hundreds of turbines, whose wakes can affect each other. Now, engineers at MIT and elsewhere have Read more about A new method boosts wind farms’ energy output, without new equipment[…]

“Switch to solar panels to help save the planet,” they say. And they’re (mostly) right. Solar panels are a great source of clean energy because, unlike fossil fuels, solar energy doesn’t produce harmful carbon emissions while creating electricity. But how “clean” is the process of creating solar panels? Ironically enough, solar panel production is reliant Read more about The Environmental Impact of Solar Panels[…]

The aviation industry’s attempts to go green are getting a boost from an unlikely place: carbon-neutral jet fuel pulled from thin air. That may seem far-fetched, but it’s a concept that engineers at the Swiss Federal Institute of Technology (ETH) have not only proved experimentally, but apparently proven again at scale. Even better, the fuel Read more about Pull jet fuel from thin air? We can do that, say scientists[…]

Wave Swell Energy’s remarkable UniWave 200 is a sea platform that uses an artificial blowhole formation to create air pressure changes that drive a turbine and feed energy back to shore.
