Renewable and Nonrenewable Resources

By Elisa Lazarte

​What is Renewable Energy?

Renewable energy comes from natural resources that are naturally replenished, such as sunlight, wind and waves.

​Types of Renewable Energy

​What is Non - Renewable Energy?

Non-renewable energy comes from natural resources that are not naturally replenished, such as oil and coal.

Solar Power

The use of pollution-free direct sunlight probably has the greatest potential of all the forms of solar energy for becoming a major source of energy in the future

• But today it is not yet used in any major way.

Each year the Earth receives from the sun about ten times the energy that is stored in all of its fossil fuel and uranium reserves put together. 

​

A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity

The photovoltaic effect is a physical and chemical phenomenon.
