Although we have the necessary resources and technology to meet most of our energy needs in the future with renewable energy, until fairly recently one key strategy has, for the most part, been overlooked in North America. This strategy involves the cooperative or collaborative installation and ownership of renewable energy projects at the local, community level.

CSE projects are somewhat similar to Community Supported Agriculture (CSA). The main difference, however, is that instead of investing in potatoes, carrots, or cucumbers, with CSE, local residents invest in energy projects that provide greater energy security and a wide variety of other benefits.
