To put the $370 billion in subsidies to work, the US needs to build new infrastructure and manage a lot of regulatory hurdles.

Here are two possible forms of regional geoengineering.

While a US transition to renewable energy by 2030 is possible, streamlined policies with clear goals and incentives are necessary to get there, says an industrial engineering professor.

While Congress considers new renewable energy incentives, Texas’ sprawling wind farms tell a story about renewable energy ownership in the US – and who benefits from subsidies.

An economist explains coal power’s rise and fall in charts.

"In principle, we can now scale semitransparent organic solar cells to two meters by two meters, which brings our windows much closer to reality."

The costs of three frequently touted solutions – tree planting, carbon capture and geoengineering – would be astronomical to make even a tiny dent in the carbon accumulated in the atmosphere.

This family of crystalline compounds is at the forefront of research seeking alternatives to silicon.

Sometimes wind and solar power produce more electricity than the local grid can handle. Better energy storage and transmission could move extra energy to where it’s needed instead of shutting it off.
