"Unlike large fossil fuel generation, clean energy technologies tend to become rapidly cheaper over time. In the past eight years, we have seen costs for wind drop by 40 percent, solar by over 60 percent, and energy-saving LED lights by 90 percent. In many places, clean energy is now, and will remain, cost-competitive as technology costs drop. While these trends alone will not be able to keep the U.S. on a trajectory to avoid the most dangerous effects of climate change, they bolster the case that clean energy is an attractive, innovation-oriented growth option for our economy, and one that undoubtedly many stakeholders will be pressing for in the months ahead and in future elections."  - Brookings Institute
