Which of the following is a renewable energy source?
Renewable resources include solar energy, wind, falling water, the heat of the earth (geothermal), plant materials (biomass), waves, ocean currents, temperature differences in the oceans and the energy of the tides.
What are primary and secondary energy sources?
Activity Overview: Primary energy consists of unconverted or original fuels. … Secondary energy includes resources that have been converted or stored. For example, primary energy sources include petroleum, natural gas, coal, biomass, flowing water, wind, and solar radiation.
What are the 5 main renewable energy sources?
There are five major renewable energy sources
- Solar energy from the sun.
- Geothermal energy from heat inside the earth.
