To the Editor:
There seems to be a lot of confusion about Princeton’s program to aggregate the town’s electricity purchases. This program provides both a lower rate and electricity supply with renewable energy content (50% for all, 100% for those who choose that option).

Let’s be clear: when Constellation purchases renewable energy credits (RECs) from a solar or wind developer in the local grid (aka PJM), it is promoting the installation of renewable energy projects by providing additional revenue so that project investors can recapture their capital outlay over a 15- to 25-year term. Every kilowatt-hour of electricity that a wind or solar project generates — at zero emissions — and puts into PJM is a kilowatt-hour not generated by coal or natural gas. That means cleaner air, not just for you, but for the entire region as well.

Perhaps you’ve read the news: renewable energy will produce more electricity in the United States this year than coal will. You should be proud of Princeton for doing its part to move us toward a cleaner, safer, and more sustainable planet.
