You might think that improving your home’s energy efficiency requires a significant investment in new high-tech windows, solar panels for your roof or even overhauling your HVAC system. Although it’s true that making any of those big investments can have a significant impact on your home’s energy consumption, little changes can make just as much of a difference. For example, it’s estimated that the United States spends more than $300 billion a year on energy that is wasted because of drafty doors and windows.
