Sustainable energy 

All energy sources deliver the same product, and the electricity is there for you – when and where you need it. The refrigerator keeps running, the lights keep turning on, the A/C (or furnace) keeps you cool (or warm) regardless of the source that generates it – coal, sunshine, wind. However, in the community and around the globe, the source makes a big difference.
