In addition to the Sun, other energy sources include:
* Fossil fuels: These are the remains of plants and animals that lived millions of years ago. They include oil, gas, and coal. Fossil fuels are used to generate electricity, power vehicles, and heat homes and businesses.
* Nuclear power: This is a type of energy that is produced by splitting atoms. Nuclear power plants generate electricity by using the heat from nuclear reactions to turn water into steam.
* Renewable energy sources: These are energy sources that are replenished naturally. They include solar power, wind power, and hydroelectric power. Renewable energy sources are becoming increasingly popular as ways to reduce our dependence on fossil fuels.
The main energy source for the future is likely to be a combination of renewable energy sources and nuclear power. These sources are clean, sustainable, and safe.
