Bill Gates in his own blog:
The United States has made remarkable progress over the last two years toward a future where every home is powered by clean energy. Thanks in part to historic federal investments, we’re on a path to use more clean electricity sources than ever before—including wind, solar, nuclear, and geothermal energy—which would reduce household costs, cut pollution, and diversify our energy supply so we’re not dependent on any one thing.
But to take advantage of this opportunity, we need to first bring our grid into the 21st century. (This is an issue in other places around the world, too, but I’m going to focus on the U.S. here.) The way we move electricity around in this country just isn’t designed to meet modern energy needs.
