The Department of Defense could be a perfect place to deploy some of the early-stage energy efficiency technologies because they can be both co-researcher and customer. However, ITIF President notes efficiency is only a "transitional" strategy. Countries like China and India can't reduce the increases in their carbon emissions with efficiency alone. They will need new clean technologies, which means spending money on R&D. Low-carbon energy technologies are necessary to combat global warming on the proper scale.
