Energy efficient retrofits to existing housing stock provide a great return for residents and contribute to energy sustainability for communities.

RMI has a great piece about how properly valuing the benefits of the retrofits can improve financing options.

Our colleagues in the WealthWorks / Wealth Creation in Rural Communities work at MACED have coordinated a program, How$martKY, that works with electricity cooperatives to help make cost effective energy efficiency improvements for cooperative customers.
