California is considering a controversial proposal for utilities to charge customers for electricity based partly on household income. Two scholars explain how this approach could benefit everyone.

"The impact of wind turbines on house prices is much smaller than generally feared," says Maximilian Auffhammer.

Higher oil prices and better drilling technologies have

Researchers have engineered a new perovskite solar cell that is stable and energy efficient.

Solar development isn’t always good for the land, but pairing it with agriculture can produce multiple benefits.

An online model enables users to calculate the least-cost strategy for a specific regional grid under various assumptions; outcomes vary widely from region to region.

When the Moon blocks the Sun during an eclipse, utility suppliers have to pull power from the grid to make up for gaps in solar energy.

Detroit’s plan to install solar panels in city neighborhoods may conflict with residents’ desires to see lower energy bills and more housing.

Militaries around the world are rapidly developing science fiction-like laser weapons, motivated in part by the growing threat from swarms of drones.
