Geothermal and Hydroelectric Energy

In the recent past, humans have been looking for and trying out alternative sources of renewable energy to reduce dependence on fossil fuels. How can the energy from volcanoes be tapped for human use?

• The lava can be used for cooking.

• The energy from the magma can be used to heat water.

• Geothermal energy can be used to generate electricity.

• Geothermal energy can be tapped to produce steam used for heating showers.
