If you want to get honest, unbiased advice on ways to save money on your home energy costs, call the Energy Trust of Oregon at 1.866.368.7878 or send them an email at firstname.lastname@example.org to request more information about home energy conservation programs. You already pay for ETO programs and services through a small surcharge on your monthly utility bills -- so you should use the program you've already paid for. ETO is a nonprofit whose mission is to help the Northwest reach its conservation goals. They will help you evaluate all your energy and money-saving options at no cost, and they aren't selling anything.
So don't fall for shady promotional "free lunch" deals, no matter how strong you think your sales resistance is. Companies that market like this are a lot hungrier and more experienced at this game than you are.
