Paying extra for renewable power?
Many power companies offer a renewable power option. You pay more and some or all of your electricity will be “from” renewable sources. The price is low. Supposedly renewable energy certificates (RECs) are similar. One can pay ~$55/year and supposedly achieve the equivalent of 100% renewable power. https://www.terrapass.com/product/productres-recs
Sounds wonderful – a way for anyone to easily erase their carbon footprint due to electricity use. But is it legit? – some say that the utility is playing an accounting game and charging extra for power while not actually changing anything. They already installed some amount of renewable power for other reasons.
It’s not at all clear to me. My guess – that at the low cost involved, everyone should do it even if the effect is small. But don’t say “I’ve done my part” and stop there.
