Many people are aware that Iceland has the cleanest energy in the world by far. The island-nation generates 100% of its electricity from renewables such as hydroelectric and geothermal sources, and it’s also flirting with wind power. What those same people might not realize, however, is that this results in some of the cheapest electricity in the world.

As an Exelon company, Constellation Energy is part of one of the biggest — and historically most polluting — corporations in North America. Given Exelon’s vast production energy, ranking on the PERI Toxic 100 list is perhaps not that surprising. The good news is that Exelon is upfront about its room for eco-friendly improvement and make it easy for Constellation customers to go green, too.


Generally, the generation of electricity is unrelated to anything on your bill. Power plant companies generate electricity and sell it to utilities as well as retail electricity providers in deregulated areas. The electricity is then resold to you, the customer. Transmission and distribution is taken care of and charged to you by your utility, regardless of what company supplies the electricity. These charges are separate from the supply portion of your bill.
If you’re on a fixed rate tariff with your current supplier, check to see if there’s an exit fee for leaving the contract early. If there is, you’ll need to factor this cost into your price comparison as it could swallow up some of the potential savings. If you can supply your tariff name when you get a quote, we can take your tariff into account when showing you the savings you could make.
