Shopping for a plan based on renewable sources is no different than shopping for any other kind of plan — you calculate your costs the same way, look for the same fees, and weigh in customer satisfaction and other perks. The one thing that’s different is also looking at what percentage of your energy comes from renewable content in the EFL. That number can swing from as low as 0 percent all the way up to 100 percent, with the majority of plans that partially offset energy with renewable content hovering around 15 percent.
