The average American family spends about $1,900 per year on home energy bills. Much of that goes out the window, quite literally. According to the Department of Energy, over half of home energy is wasted in inefficient appliance and under-insulated abodes. On the bright side, most efficiency improvements will pay for themselves quickly, and save you loads of cash in the long run. And there are plenty of free home energy assessment tools out there for owners and renters alike, as well as billions of dollars worth of state and federal incentives.
A great place to start is the Home Energy Saver site, which will help you do a detailed home energy audit, then connect up with tax credits, rebates, and financing for efficiency upgrades. There’s also EnergySavers.gov, which has handy tips for greening both your home and your ride. Suggestions range from big investments (replacing windows and adding insulation), to quick fixes that pay for themselves in less than a year (or immediately), like weatherstripping, turning down your water heater, and slashing ~$200 per year off the vampiric tendencies of undead electronics with a power strip diet. If you prefer to be in the hands of a startup instead of government researchers, take a look at WattzOn, which hooks you up with personalized home efficiency and cash incentive suggestions.
If you want to go the high tech route, you can also take a thermal image of your personal palace with an infrared camera, which will give a stark visual of where heat leaks out while Jack Frost is nipping at your nose (which happen to be the same spots where heat sneaks in during the summertime). As a bonus, renting a thermographic camera will help you investigate paranormal activity, as well as spy on Obama’s R-values.
