Electric sector transitions by technology (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption U.S. electricity grid needs to be 80% clean (up from 40% currently) for reaching the U.S. goal of reducing emissions by 50% by 2030. The chart shows the required new electricity generation capacity buildout to achieve this goal (right) and compares with the historical buildout rates (left). The U.S. will need to double its renewable energy buildout rates.
