A small, lightweight fission system could help spacecraft travel huge distances. 

"A solar thermal fuel is like a rechargeable battery, but instead of electricity you put sunlight in and get heat out."

Over and over we’ve gotten scientific wake-up calls, and over and over we’ve hit the snooze button. If we keep doing that, climate change will no longer be a problem, because calling something a problem implies there’s still a solution. By Bill McKibben.

Palau, under threat from sea level rise, wants to have 70 percent renewable energy by 2050

President Trump has promised to revive coal's flagging fortunes. Is it possible?

Arizona-based electric vehicle startup Atlis Motor Vehicles claims that it achieved “a full charge in 12 minutes, 35 seconds” of a prototype battery pack that it believes is scalable for its upcoming electric pickup truck. The company describes this as “the test of their first large-scale prototype pack used a public DC fast charge station,” but the prototype was only a 3 kWh pack.

The natural gas "bridge" to sustainability may be shorter than expected.

Being able to control plasma that is hotter than the Sun is notoriously difficult.

India, the world's third largest oil importer, says it abides by sanctions imposed by the United Nations, but not those of other countries.

An oil spill that has been quietly leaking millions of barrels into the Gulf of Mexico has gone unplugged for so long that it now verges on becoming one of the worst offshore disasters in US history.

Seawater is a complex cocktail of useful minerals, but it’s hard to separate the ones we need. Now a team of scientists from Australia and the US has developed a new water desalination technique that can not only make seawater fresh enough to drink, but recover lithium ions for use in batteries.

The fossil fuel era won't last forever. And a new set of countries will find their reserves of lithium, copper and rare earth metals are in high demand. By Andrew Barron.

The push to provide nuclear power to Saudi Arabia has divided U.S. policymakers. By Steven Mufson.

Current EV batteries could be charged much quicker, researchers say.

A rechargeable battery that works at –70° C could be used in some of the coldest places on Earth or other planets.

Bitcoin could consume 7.7 gigawatts by the end of 2018.

A country getting all its electricity from a combination of wind, solar and hydro sounds like science fiction. It's not.

The fossil fuel industry brings in a staggering amount of money to countries all around the world, but that doesn't mean it will last forever.

Despite tariffs that President Trump imposed on imported panels, the U.S. installed more solar energy than any other source of electricity in the first quarter.

Latest study suggests that emissions of the potent greenhouse gas could be coming from faulty equipment.

Fossil fuel proponents may claim that even renewables or “clean energy” have harmful impacts on the environment to justify continued drilling and mining — but that’s not the whole truth. Here’s the reality — all forms of energy production, and really any form of human development, can have impacts. But renewables like wind and solar are called clean for a reason. Their impacts are many times smaller than those of other energy sources. Scott Tinker’s recent commentary in The Hill arguing the environment damage renewable cause contains outdated and incorrect information about renewable energy.

The firm says tests at Japanese factories had "deviated from the prescribed testing environment".

That’s profoundly concerning for climate change.
