What Is Energy Efficiency? - 02nd November 2014

What is energy efficiency?
What is energy efficiency?
The best way to understand this idea is through examples as examples,
When you replace a single pane window in your house with an energy-efficient one, the new window prevents heat from escaping in the winter, so you save energy by using your furnace or electric heater less while still staying comfortable. In the summer, efficient windows keep the heat out, so the air conditioner does not run as often and you save electricity.
When you replace an appliance, such as a refrigerator or clothes washer, or office equipment, such as a computer or printer, with a more energy-efficient model, the new equipment provides the same service, but uses less energy. This saves you money on your energy bill, and reduces the amount of greenhouse gases going into the atmosphere.
Energy efficiency is a win-win.
LED lighting is an innovative tool in the energy efficiency arsenal, which includes a huge variety of proven technologies and strategies that any nation, including developing ones, can use to create a cleaner and more prosperous future.
Energy efficiency is not energy conservation.
Energy conservation is reducing or going without a service to save energy.
For example: Turning off a light is energy conservation. Replacing an incandescent lamp with a compact fluorescent lamp (which uses much less energy to produce the same amount of light) is energy efficiency.
Both efficiency and conservation can reduce greenhouse gas emissions.
