SustainLane has put together a list of the top 10 cities (sadly, only out of the 50 largest cities in the US) based on the proportion of their electricity coming from renewables. Surprisingly, Oakland, CA, clocks in at the top with 17%, and Chicago comes in at ten (really, eleven, because there's a tie for 2nd) with 2.5%.
If you're familiar with the clean energy plan, then, you'd know that when we get our full complement of wind power, Springfield is going to beat the top performer, with our 20% versus Oakland's 17%. Even if you exclude the state's portion, we tie Portland for third, with 10%.
Of course, none of these cities are going to stop moving forward, and Springfield shouldn't either. We can increase that percentage in two ways: first when CWLP opens up it's green power program (wherein residents and businesses can choose to buy more renewable energy, for a slight increase in cost), and second by reducing our overall energy use--since our wind power commitment is for a set capacity (120MW), any decrease in our overall electricity consumption will get reflected as an increase in the proportion of our electricity coming from wind.
Obviously, we're not doing this so we can top someone's list (especially, when that person restricts the list to the 50 largest cities in the country). But it's always nice when you can ratchet the right thing to do to a little virtuous competition.
