Renewable energy is simply the energy that is produce by or came from the natural resources. Let us first see the term renewable. What does it mean? It means it is changed or replenished naturally. An example of natural resources that can produce renewable energies are one that comes from the sunlight, rain, wind, geothermal heat and also tides. Renewable energy comes in many forms and it has been subjected to many researches. Some have been already functioning and is helping the environment.
The form of the technologies that concentrates of focuses on renewable energies are solar power, micro hydro or hydroelectricity, wind power, biofuels, biomass (energy came from the plants) and others. They are very useful in their own uses and it cost less to consumers who opted to use it. They are even contributing to the non-pollution of this planet we are living and having benefit of their own. It is indirectly helping someone while enjoying the benefit of renewable energy.
Then why is it important that renewable energy should be used? Because when we continually used the energy that was produced by limited materials that can be gone at any moment then we will turn to crisis if we cannot get that kind of material anymore. Getting that kind of material will cost more and also caused damage to the environment. Our product is far less than the costs for those materials.
