Hi, just brief FYI on how the evolution of the "green power" program (what you get with REC purchases) was for 2013. For those of us that live "in the shade" (i.e. hidden under trees) and can't invest in community solar projects, it gives the option to instruct our utility to purchase our Wh from renewable sources at a symbolic premium. PSE Green Power in 2013 is: 75% Wind (Purchased from WA,OR,ID,CA) 11% Livestock Methane (WA,OR) 10% Low Impact Hydro (WA) 3.5% Solar (WA,OR,CA) 0.5% Landfill Gas (WA) This shows an IMO positive big increase in wind (up to 75% from 50% some years ago) less landfill gas (used to be 20%) & wood waste (0% now). Compared to the regular energy mix for PSE in 2013: 42% Hydroelectric 30% Coal 18% Nat Gas 8% Wind 1% Nuclear 1% Other If you are using PSE and are not signed up, I recommend doing so even if you have solar panels. Other utilities may brand their programs differently but they all have to offer REC options to consumers up to a minimum amount.
