Long-shot money is flowing into start-ups that seek the energy of the stars. Driving the investments is a rising alarm about global warming.

Oil prices hit multi-year highs on Monday buoyed by recovering demand and high natural gas and coal prices encouraging users to switch to fuel oil and diesel for power generation.

Major Chinese energy companies are in advanced talks with U.S. exporters to secure long-term liquefied natural gas (LNG)supplies, as soaring gas prices and domestic power shortages heighten concerns about the country's fuel security, several sources said.

Winterization of natural gas facilities in Texas is slow going.

The infamous Indian Point nuclear plant, located roughly 30 miles north of Manhattan, shut down earlier this year. To many, the shutdown was a victory following decades of protests about safety and environmental concerns. Here’s the problem: When operating, Indian Point provided more electricity than is produced annually by all solar and wind in New York state.

Only ecodesign stoves can be legally sold from 2022 – but experts say the standard is shockingly weak

NASA has devised a plan to ensure the volcano underneath Yellowstone remains dormant in order to prevent a possible natural disaster.

With a number of recent breakthroughs, the race is on to prove that nuclear fusion is not only possible, but integral to a clean energy future

California is closing Diablo Canyon, which is a source of clean power, as it faces an energy emergency and a mandate to eliminate carbon emissions. Why?

China faces mounting pressure to ramp up coal imports and ensure supplies to keep lights on, factories open and water flowing as a severe power crunch roils the northeastern industrial heartland.

Catalyst based on nickel and iron allows electrical current to be harvested from the breakdown of urea.

Back in 2013, Techdirt started writing about the boring-sounding Investor-State Dispute Settlement (ISDS) system. It was so boring, we decide to use a better term for it: corporate sovereignty. It's an appropriate name, since this system of...

Bitcoin mining will only contribute to 0.9% of global carbon emissions even if the coin's price were to hit a mind-boggling $10 trillion by 2030.

From upstate New York hydroelectric plants to volcanoes in El Salvador, some Bitcoin miners are looking for cheap energy—just as long as it’s renewable. Bitcoin has earned a notorious reputation for its carbon emissions due to the network's energy use, which resulted in a series of tweets in May by Tesla CEO Elon Musk, who said his electric car company would no longer accept Bitcoin for payments because of environmental concerns surrounding the use of fossil fuels to mine the asset. U.S. lawmakers, like Sen. Elizabeth Warren, have also criticized the energy expenditure of the cryptocurrency.

As global carbon emissions that stem from fossil fuels keep adding to our ever-growing climate change issue, energy companies have turned their focus on renewables to generate fuel. One of those companies is Synhelion from Switzerland. The company harnesses the energy of the heat of the sun and converts the collected carbon dioxide into synthetic fuels, in turn offering a green and sustainable solution.

The only way to really address the climate crisis is through politics, policymakers and legislation.

The technology is there, but public perception needs to change.

Tesla has also built several utility-scale energy storage systems around the world, but typically hasn't functioned as the retail electricity provider there.

The lithium-ion batteries in our devices degrade over time and come with a large environmental cost. Are there better ways to store and carry energy that are kinder to the planet?
