Have you ever heard about renewable energy sources? Well if you haven’t, you should know it’s a good way to contribute to the saving of the planet as it can replace conventional fuels in few distinct areas such as electricity generation, wind and air heating or cooling and motor fuels.

First of all, renewable energy is commonly used to refer to the energy that originates from sources which are replenished on a human timescale. Renewable energy might come from sunlight, wind, rain, tides, waves, and geothermal heat but wind, solar and biomass are three main renewable energy sources.

Moreover, solar energy, which relies on the nuclear fusion power from the core of the sun, can be collected and used in many ways. For example, lots of people use solar energy to heat water with solar collectors. As for wind power, wind energy can be used to pump water or generate electricity. Finally, the most modern forms of biomass (the energy from plants are methane generation and alcohol production for automobile fuels.

To sum up, our planet is about to get destructed. That’s why we should adopt an environmental way of thinking and a good way of showing our environmental conscience is using renewable energy. But we have to admit that using renewable energy might be difficult because methods of exploiting these forms of energy are not advanced yet.
