Clean Energy Works connects champions of energy efficiency and renewable energy with resources that accelerate investment in clean energy solutions. Our work on financing energy efficiency building upgrades won a Fire Award for high-impact innovation at the Bloomberg New Energy Finance 2015 Future of Energy Summit, and the idea of harnessing the strength and scale of utilities to attract and deploy capital for cost effective clean energy solutions won a top award from the Climate Strategies Accelerator in 2017. Pay As You Save for Clean Transport was endorsed by The Global Innovation Lab for Climate Finance as a top finance instrument in 2018.

Clean Energy Works focuses on business plan development for utilities that are using PAYS® to update their investment model for the 21st century. We promote competitive, market-based approaches that clear barriers for entrepreneurs with innovative solutions and spur new job opportunities. A nonprofit organization, we also provide advisory services to policy-makers, public interest groups, and companies interested in rapidly scaling up investment in clean energy solutions.
