Wind solar renewable energy sources.

Wind energy is an indirect form of solar energy created by a combination of factors including the uneven heating of earth s atmosphere by solar radiation variations in topography and the rotation of earth. Solar wind hydropower and other renewable energy sources currently account for a small share of global energy. Electricity generation air and water heating cooling transportation and rural off grid energy services. Available sources of renewable energy in pennsylvania include solar geothermal wind hydropower and biomass.

But they re growing quickly and can play a key role in tackling climate change. Several forms have become price competitive with energy derived from fossil fuels. Renewable energy often provides energy in four important areas. Clean energy has far more to recommend it.

By 2030 the lcoe ranges of both conventional coal and gas technologies as well as wind and large scale solar converge to a common range of a 50 to a 100 per megawatt hour. Renewable energy often referred to as clean energy comes from natural sources or processes that are constantly replenished. Wind is the lowest cost large scale renewable energy source while rooftop solar panels are competitive with retail electricity prices. Solar is the conversion of sunlight into electricity by either solar photovoltaic pv panels or solar thermal systems.

People have been putting wind energy to use throughout history to propel sail boats mill flour from grain and pump water. Following is a brief description of each. Renewable energy is energy that is collected from renewable resources which are naturally replenished on a human timescale such as sunlight wind rain tides waves and geothermal heat. Nearly a third of the earth s electricity will come from renewables by 2024 according to the international energy agency.

That s because renewable energy sources such as solar and wind don t emit carbon dioxide and other greenhouse gases that contribute to global warming.
