Renewable energy

 Renewable energy can defined as the energy from natural resources mainly from rain, biogas, waves, sunlight, geothermal power or energy and other natural resources. The most striking statistics is that about 20 percent of the world's energy comes from renewable resources compare to non -renewable energy. This sad statistic has motivated the world leaders to implement ways to encourage the population to use this type of energy. This is because of its environmental significance. Renewable energy is a type of energy harnessed without exhausting natural resources such as vestige fuels and timber. This energy is independent on fossils to generate electricity. This energy is maintainable as it is imitative from sources that always consistent.
 Advantages of Renewable Energy

 It is extremely maintainable since it originates from everlasting sources
 This energy does not produce any greenhouse gas. The gases are always clean and environmental friendly.
 It is very cost effective since no fuel is needed to sustain this electricity firm. No labor is required to operate this energy hence less cost.
 The energy has numerous benefits to the immediate communities since most of them are located in local areas where other forms of energy such as electricity are rare.
 A particular form of renewable energy like geothermal steam firms occupies less geographical area compared to other types of energy.
 Biomass energy assists to reduce on the volume of garbage.
 In numerous scenarios when an individual has access to renewable energy source, like solar power, fitted to their residence, they will distribute the energy to reduce the depletion of natural resources.

 Majority of renewable energy originates from the sun, which is the main source directly or indirectly. Renewable energy harnessed by solar energy hitting directly the people's house roofs. This generates energy used for domestic chores such as cooking, lightening and heating and many more other uses once connected to domestic reservoir.
 The sun's heat also energies the wind and current which is harnessed by wind turbines. The suns heat cause wind to evaporate results to vapor that rotates the turbines causing the formation of hydroelectricity. The inorganic matter from plants is used to manufacture biomass that produces electricity for domestic tasks. This energy type referred to as bioenergy.
 Hydrogen is a component found in many organic composites together with water. It is also the most profuse element found on the Earth. Since it has many other elements and when combined with these elements, like with oxygen results to water. Hydrogen is a fuel when burned with these elements to generate electricity.
 Another form is the ocean energy, which results as result of tidal variance resulting to tidal energy. On top of tidal energy, there is the ocean's wave energy, which is compelled by the tides and the winds foundations. The sun heats the ocean surface more than the ocean inner deeps, making a temperature variance that results to an energy source. These forms of ocean energy can produce electricity when harnessed well.
 People should adopt this type of energy to achieve a cheap and maximum environmentally safe energy and preventing degradation.
