One of the main ideas behind home efficiency improvements is that you have to spend money to save money. While this seems counterintuitive, it adds up when you examine it further--although home efficiency improvements cost money initially, they save you money in the long run by lowering heating and cooling bills and reducing the amount of energy required for you to live comfortably. And, although home efficiency projects cost money to start, many can be included on your Federal Tax Return, making you eligible for tax credits for consumer energy efficiency. Aside from being financially beneficial, home efficiency improvements are also environmentally friendly. Using less energy at your home has several positive environmental consequences including less burning of fossil fuels and a decrease in air pollution.
