RENEWABLE & NON-RENEWABLE SOURCES

Renewable energy sources are those that are already present in nature and that do not run out, such as sunlight, wind, sea waves, or the heat of the earth's interior.

The best-known renewable energies are:

Geothermal energy 

is generated from the heat 

accumulated in the earth's interior.

The advantages of renewable energies are that they do not pollute the environment, they are infinite because they do not run out and are regenerated naturally and, furthermore, they are respectful of health because they do not generate toxic waste.

The disadvantages of renewables are that the same natural resources are not found in all parts of the world, there are countries with few hours of daylight, others that do not have access to the sea, others with very dry climates and little rain that make it difficult to store water...

Non-renewable energy sources are those which, although they are also present in nature, are depleted as we use them, such as coal, oil, nuclear energy or natural gas.
