A new report jointly produced by the Information Technology & Innovation Foundation and the Breakthrough Institute compares the U.S.’s competitiveness on the clean energy front with China, Japan, and South Korea. What they found confirms what others have written about of late: that the U.S. is now lagging in the innovation game it once ruled. According to the study, public investments in clean energy in those countries far outpace U.S. investments. If the gap persists, the U.S. will find itself importing the overwhelming majority of the clean energy technologies it deploys, from wind turbines and high-speed-rail materials to solar cells and nuclear-plant equipment. It’s a troubling survey that underscores how much ground the U.S. needs to make up to become a world leader in innovation and green energy.
