Q. What is green energy and how can I support it?

This is a great question and a very important topic. “Green” or renewable energy is energy that comes from a source that is continually replenished; some examples are sunlight, wind, and water.

By now, most people know that using energy efficient products, like compact fluorescent light bulbs (CFLs) can lower their monthly electric bills. To help customers save even more money, NHSaves—the utility-sponsored energy efficiency collaborative—has again published a catalog of discounted energy efficient lighting products both in print and online.
