Energy efficiency is gaining in importance as we face a carbon-constrained world. Energy efficiency means “using a reduced amount of energy while providing the same level of service”.
Some examples of this include:
- Replacing single pane windows with energy-efficient windows
- Saves on heating and cooling costs – in the winter, the new window keeps heat inside the home so you save energy (and $$$) by not having to use as much heat; in the summer, the windows keep hot air out and cool air in, saving money on electricity for air conditioning.
- Replacing old appliances with new Energy Star efficient ones
- Uses less energy and can do more – from televisions and refrigerators to computers or other office equipment, using Energy Star rated energy-efficient appliances provides the same (or better) service but uses less energy. When added across household and office appliances this can be a meaningful savings every year.
Taking steps to become more energy-efficient does not mean that we should stop trying to conserve energy as well. To give an example: if you change from incandescent to compact fluorescent lights, you are being more energy efficient. If you turn off lights you are not using, you are conserving energy. The two actions together have the most impact and provide the most benefit.
