Renewable energy

Renewable energy is energy that can never be extinct. Some renewable energy sources are solar, wind, hydro power, biomass, and geothermal.Renewable energy is energy that is created from renewable resources, which can be used sustainably and are naturally regenerated. Some nonrenewable sources are fossil fuels and coal. It doesn't harm the environment, doesn't pollute. It is used for electricity generation. It is clean and does not contribute to global warming of greenhouse effects but it is costly. Renewable energy is a new technology. It is being looked at a possible source of electricity for the future. Each renewable energy source has its benefits and costs. About 16% of the global final energy is consumed everyday and the age of oil and natural gas will come to an end. And to meet the crisis, we need alternative sources. Solar energy is renewable energy. Solar energy units can be installed on open rooftops or at any place where sunlight is available. Wind energy captured with wind turbines can produce electricity. Sunshine and the wind can turn water into an energy called hydroelectric energy. We can have bioenergy from bio-mass of plants. Hydrogen is a source of energy. If hydrogen is separated from another element, it can be burned as a fuel to produce electricity. We can get geothermal energy from inside the earth. We can have ocean energy from the tide and energy. However, renewable energy provides 19% of electricity generation worldwide. Renewable power generators are spread across many countries and wind power alone already provides a significant share of electricity in some areas. On the other hand, solar hot water makes an important contribution to renewable heat in many countries. Renewable biofules have contributed to a significant decline in all consumption. But is true that all the renewable energies come from neutral sources.
