How are geothermal and hydroelectric energy similar?

Both are produced from steam and both are renewable source of energy.

Explanation:

Hydroelectric energy is produced by converting the kinetic energy of water into electric energy. It is a renewable source of energy and the water can be used again.

Geothermal energy is the thermal energy that is obtained from the earth. This thermal energy can be utilized to produce renewable energy. By passing a water stream and letting it to evaporate and then utilizing the steam, electricity can be generated.

they both use turbines to produce electricity.

Both convert naturally occurring energy into electricity.
