What is Energy Efficiency?
Energy efficiency means using less energy to perform the same function. Appliances and machines are energy-efficient when they use less electricity, water, or gas to accomplish the same task.
Why is energy efficiency important?
In California, energy efficiency and conservation are high priorities. A major goal is to actually save the amount of energy generated and used altogether. Sometimes we call this unused energy a “negawatt” — a watt of energy that’s never been produced because it was unnecessary. Avoiding the use of energy in the first place is the cleanest and least expensive option — one watt never used is one that doesn’t pollute. That’s why energy utilities prioritize energy-efficient technology and conservation practices, even over renewable energy sources.
How can I achieve energy-efficiency?
Technological innovation plays a big role in improving energy-efficiency. Many products available today are designed to be energy-efficient. For example, newer, compact fluorescent light bulbs use one-third of the energy of older, incandescent bulbs to light the same space. Energy Star-certified washing machines clean clothes as effectively as a less energy-efficient or water-efficient model, but with 25% less energy and 35% less water.
