Energy efficiency is "using less energy to provide the same service".
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 bulb with an light-emitting diode or LED bulb (which is
several times better that uses much less energy to produce the same amount of light) is energy efficiency.
Both efficiency and conservation can reduce greenhouse gas emissions.
Why reducing electricity use is a good idea?
Reducing your electricity use brings a number of benefits:
- Saving money:
- reducing your power bills through changed behaviours
- in the long term by reducing the need for more generators and network infrastructure
- It reduces greenhouse gas emissions which contribute to climate change. While renewable sources of energy, like the wind, play an
increasing role in our system, the vast majority of our electricity is still generated from fossil fuels like gas, oil and coal. Therefore
reducing our electricity use reduces the flow of carbon dioxide into the atmosphere.
Small changes to the way we use electricity can make a big difference.
