Advanced small modular reactors, known as SMRs, will probably have many advantages over older technology. But it's not yet known how they will stack up against other sources of electricity.
Several states, including Massachusetts and Rhode Island, have developed ambitious renewable energy targets that hinge in large part on getting their power from turbines stationed in the water.
Experts expect the wind business to remain brisk in the US and abroad, on land and offshore.
It's easier to see how customers benefit from increased grid security than it is to justify making them pay for it.
Blockchain technology could be applied to our energy grids to make them smarter, and turn energy consumers into producers.
US military bases usually get their electricity from the civilian grid, which is vulnerable to attack and to disaster. Solar-powered microgrids could protect national security, and would save money.
Smoothing out variable wind and solar is a growing problem. Instead of storing energy with batteries, utilities can adjust the power of millions of devices in buildings and homes.
