Energy Sources Quiz: How Much You Know?

There will always be sunlight so solar energy is renewable.

There will always be flowing water on Earth so humans can always make hydropower.

Once fossil fuels are pumped or dug out of the ground and burned as the fuel they cannot be replaced, so they are non-renewable.

Hydropower is created when moving water is turned into electricity, such as when water flows past a dam's turbines which run the generators making electricity.

Most of the renewable energy sources do less harm to the environment than non-renewable energy sources.

Renewable energies can be used over again or made again if they run out.

The inside of the Earth will always be hot so geothermal energy will always be available.

Most energy sources are used for making electricity but many are used as fuel for cars and trucks.

Nuclear energy uses radioactive elements found in rocks dug from the earth. Once all the rocks that have the radioactive elements are dug up and used for nuclear energy, there will be no more sources for nuclear energy.

Nuclear energy is getting the energy from splitting an atoms nucleus (fission) to make electricity.

Thermal energy is heat energy. Geothermal energy is heat from inside the earth, usually from hot water deep in the earth.

Wind energy changes the energy from the wind into electrical energy using wind turbines. The wind is renewable.

Most of the time, solar energy is light energy from the sun used to make electricity but sometimes it is used to make heat.

Non-renewable energy can be used up completely. Once every little bit has been used on earth, there is no more left.
