The most renewable energy is energy that is never used. When producing energy using renewable technology, it is a rule of thumb that every $1 spent on energy efficiency saves $3 on system costs.

We are currently working with the REC Center to help decrease their energy use. (see "Western re-examining new building" The Western Front- 05.17.07)
