If the U.S. could tap into just 2 percent of the geothermal power beneath Earth’s crust, it could supply more than 2,000 times our total annual energy consumption.

Japan will test solar power transmission from space in 2025 with a miniature space-based photoelectric plant that will wirelessly transmit energy from low Earth orbit to Earth.

Larderello is home to the world's oldest geothermal power site. The energy source was first used to power light bulbs in 1904, and now geothermal generates more than 5 percent of Italy's clean ...

While conventional solar panels on Earth can only produce power during daylight hours and are at the mercy of weather conditions, orbital solar arrays could beam massive amounts of clean energy to ...

In a controversial experiment, a team of physicists investigated whether we could harness the Earth's rotational energy to generate electricity. It's a deceptively simple idea that researchers ...

Solar power plants in space, although difficult to build, would produce energy 13 times more efficiently compared to those on Earth, as their view of the sun is not obscured by atmospheric gases.

In those places—generally volcanic hot spots where magma flows at shallow depths in the Earth’s crust and underground water reservoirs—geothermal energy can be a substantial source of power.

The 2025 theme, "Our Power, Our Planet," focuses on promoting renewable energy and clean electricity by 2030. First celebrated in 1970, Earth Day was founded by Senator Gaylord Nelson, Congressman ...

So-called rare earth elements are essential for modern wind power. They are major components of the ultra-powerful and long-lasting magnets through which turbines generate energy.

Astrophysicist Neil deGrasse Tyson discusses 2032 asteroid collision 05:14. An asteroid nearly the size of a football field now has roughly a 0.004% chance of hitting Earth in about eight years ...

Imagine an energy source that is not only abundant and efficient but also safer and cleaner than the nuclear power we know today. This isn’t science fiction—it’s thorium.

Scientists and engineers near the English city of Oxford have set a nuclear fusion energy record, they announced Thursday, bringing the clean, futuristic power source another step closer to ...
