Investing in Energy Efficiency

If you have completed your energy audit (link) and have already taken small steps to reduce your energy consumption (link) then you may be ready to invest in some larger purchases to continue on the road to energy efficiency. As you consider these purchases, you may also be interested in Return on investment, or ROI, on these purchases. When are you likely to recoup the cost invested, and is the extra cost worth the energy savings? Are these investments in Energy Efficiency worth it? Take a look at different “levels” of household improvement and their corresponding ROI.
