ENERGY SOURCES

WHAT ARE ENERGY SOURCES?
They are natural resources that we can use to generate different forms of energy. Then we can transform that energy for various purposes.

There are two types of energy sources: renewable and non-renewable.

NON-RENEWABLE ENERGY SOURCES
They come from natural resources that are limited. It would take millions of years to generate these sources of energy. The most commonly are fossil fuels (oil,coal and natural gas) and nuclear energy (radioactive materials)

RENEWABLE ENERGY SOURCES
They comme from natural resources that we can´t set up completly. These include hydroelectric, solar, marine, geothermal, and biomass.
