The Ultimate Guide to Renewable Energy: Top 7 Strategies

What is Renewable Energy?

Renewable energy is energy that is derived from natural resources that are replenished on a human timescale and are therefore virtually inexhaustible. Examples of renewable energy sources include solar energy, wind energy, hydro power, geothermal energy, and biomass energy. These energy sources are considered renewable because they are constantly replenished by nature and do not run out like finite resources such as coal, oil, and natural gas. The use of renewable energy is becoming increasingly popular due to concerns about climate change, energy security, and the environmental impacts of traditional energy sources.

The most popluar renewable energy sources currently are:

1. Solar energy

2. Wind energy

3. Hydro energy

4. Tidal energy

5. Geothermal energy

6. Biomass energy
