The generator may also be turned using hydro energy harnessed by dams, or by steam produced by nuclear fission. This conductor is tapped on to a network of transmission lines, distribution lines and transformers, to deliver electricity to our homes, offices and manufacturing plants. The transformers are used to convert the electricity from the voltage used for distribution to the voltage used at the service point. The biggest electricity consumption in your home is from your heating and air conditioning equipment. Older, less insulated homes use even more electricity.
Older appliances are less energy efficient and cost more to run, too.
Water heaters are usually the second largest user of electricity in your home. There are a few things you can do to save electricity and save money in the long run. Make sure your home is insulated properly. Ceiling, wall and floor insulation reduces heating and cooling costs, while helping to keep your home cooler in the summer and warmer in the winter. Set your water heater temperature to 120 degrees.
