Energy inequality will have to reduce substantially by 2050 to maintain a safe climate and decent living standards for all.

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.

The US electricity grid is actually five regional grids, and it's hard to share power between them. A macrogrid could bridge the gaps, making electricity cheaper and more reliable.

Ramping up fossil power sources is no longer a good option in an energy-supply crisis. Bring in the weather forecasters.

Electricity is only one part of the green energy puzzle we need to solve.

Consumers can play their part in reducing carbon emissions by choosing to shift their energy use to when renewable generation is at its daily peak.
