As a general definition, renewable energies are those sources that depend on natural in order to produce energy whether it is thermal, mechanical, or electrical. Like sun, wind, water, and geothermal … etc.
Those sources are considered as renewable sources when compared to fuel or gas sources as the amount of energy that could be delivered from. Taking in consideration those energies could be converted from a type to another. As; Wind energy could be converted to electrical one by using fans or wings. Thus this energy is converted from motion energy to mechanical one as a force over wings and then to electrical energy.
These types of energy have a high concern world widely. As its role in clean sustainability of environment, and its Permanente.
Finally as of our concern and role toward the environment we also keep upgrades over our lighting products that work with photovoltaic systems, as a type of these renewable energies.
