Generating electricity accounts for one-quarter of all the greenhouse gases emitted worldwide each year. That means the most important single step we can take to prevent the worst effects of climate change is to find reliable, affordable, and net-zero emission sources of power for people around the world. We should continue to deploy the renewable-energy tools we already have, like wind and solar. At the same time, we need to develop new tools that are more consistent, reliable, and available to all, and build a better, more efficient electric grid that can store and transmit clean energy when and where it’s needed.
Much of the work that could be done with electricity involves significantly reducing costs and improving quality of technologies already in use, some for a long time. Some of it, however, requires the invention of new kinds of power sources or ways to keep the waste we produce now from entering the atmosphere.
