30. Buy Energy Star appliances
When you are in the market for a new appliance, such as a refrigerator, freezer, dishwasher, air conditioner, washing machine, dryer, dehumidifier, television, oven, and more, aim to buy an “Energy Star”-certified one, as that designation means that it’s environmentally friendly and efficient — and should save you money on your energy bill. There are even Energy Star-certified windows. According to the folks at EnergyStar.gov, “More than 2,200 product models from more than 140 manufacturers were recognized as ‘ENERGY STAR Most Efficient’ in 2017. By choosing ENERGY STAR, a typical household can save about $575 on their energy bills and still enjoy the quality and performance they expect.”
