Currently, the largest portion of energy is generated from fossil fuels such as coal, oil and natural gas. These natural resources are not renewable; furthermore, as consumption is constantly growing, coal, oil and gas may eventually run out.
Fossil fuels are environmentally harmful as greenhouse gases, such as carbon dioxide and methane, are emitted into the atmosphere during their consumption.
Renewable energy sources, such as the wind, solar and hydro energy, biomass, etc., leaves a much smaller CO2 footprint and are being exploited more and more worldwide. Wind power is one of the most innovative and rapidly developing sources of renewable energy.
global wind resource is bigger than global power demand.
At this time renewable energy forms a significant part of developed countries’ energy sector. Recognizing the advantages of renewables, such as their inexhaustibility and environmentally friendly nature, the above-mentioned countries are laboring for the progress and the development of renewable energy.
