Renewable Energy Certificates seem like a great way to prove your green. I like the idea. My Electric company is offering to sell me RECs along with the electricity I consume. They market it like I'm helping renewables along. Thing is, as I think about it, I'm really not sure I can trust my electric company isn't just trying to sell the same horse twice.
With their existing green generators in place, lets say the company generates 50% green electricity and 50% coal electricity. In doing this, they also generate RECs. If I go along with their plan (and lets say that I consume 1% of the total energy available), do I have any guarantee that the energy company would work to change their portfolio to 51% green energy to accommodate the newly purchased RECs??
