What Is Energy Efficiency?

What is energy efficiency? Energy efficiency means using less energy while providing or using the same service. There are other meanings but for our purposes this is the best one.
Examples of energy efficiency include replacing single pane windows with energy efficient double pane windows. The new windows prevent the heat in your home from escaping in the Winter and keep the cool air from escaping in the Summer. Because of this the A/C runs less and saves energy. Another example is when you replace an appliance, like a refrigerator or washing machine with a new energy efficiency model. The new model provides the same service but uses less water and electricity. Therefore these new models have created energy efficiency.
Installing insulation keeps your home cool in the summer and warm in the winter. Insulation performance is measured by R-value. A high R-value means more insulation power. Depending on the the place of installation, the R-value recommendation will differ. For the biggest energy saving, add insulation in the attic. If you look across your attic floor and your insulation is level or below floor joists, you definitely need more insulation. But just because you insulation covers the floor joists doesn't mean you don't need anymore. The recommended level for most attics is R-38, around 12-15 inches. Although in very cold climates R-49 is recommended.
