This is the third day in a row that The Optimist Daily is reporting about the very rapid breakthroughs in the fields of renewable energy. The U.S. Department of Energy has just published this chart. In the past seven years, the costs of different clean energy technologies fell between 41 and 94 percent. We predict that the impact of this acceleration will soon become clear in new and more positive climate change models. Rapid ongoing innovation will make it possible to stop global warming.
