Solar panels, wind-powered turbines, fossil fuel-burning generators and water-powered turbines are some examples of electricity-generating systems that are suitable for use by individual homeowners. The ideal solution depends on the location.
Solar panels do not generate electricity at night, and the production is low on overcast days. Similarly, a wind-powered turbine needs doesn't work in windless weather. A combination of these two systems with batteries as a backup may provide enough energy.
A water-powered turbine is suitable only for locations near a water stream. However, compared to the sunlight-powered and the wind-powered systems, it is capable of providing almost continuous flow of electricity.
The cost efficiency of a fossil fuel-burning generator depends on the fuel used. This source of energy is not renewable.
