The 6 Types of Renewable Energy – And Why We Need Them Now

Traditional energy sources, such as coal or oil, are non-renewable, meaning they are finite and we will one day use up the earth''s supply. This is obviously an issue, as the entire infrastructure of our planet currently revolves around humans using vast quantities of these substances, which take thousands, or in some cases, millions of years to reproduce.

Renewable Energy: Everything You Need to Know

Renewable energy refers to energy that comes from naturally regenerating sources. These energy sources are sustainable because they can be used without running out of resources or causing major harm to the environment.

What is Renewable Energy?

Where renewable sources are those that are recyclable, clean energy are those that do not release pollutants like carbon dioxide, and green energy is that which comes from natural sources. While there is often cross-over between these energy types, not all types of renewable energy are actually fully clean or green.

Renewable energy (or green energy) is energy from renewable natural resources that are replenished on a human timescale. The most widely used renewable energy types are solar energy, wind power, and hydropower. Bioenergy and geothermal power are also significant in some countries. Some also consider nuclear power a renewable power source, although this is controversial. Rene
