Ohm Connect uses your electrical usage data to try to reduce the use of “kicker” power plants that have to come online to meet increased demand and increase pollution. Whenever you save power (intentionally or not) they give you points. Points can be cashed out for PayPal transfers or for gift cards. (CA only). You just have to make an account and link it to your utility.

They also give away free smart thermostats sometimes. I highly recommend it! You can be green and get paid for it. Win. Win.
