Wind solar renewable energy sources.

Several forms have become price competitive with energy derived from fossil fuels. But they re growing quickly and can play a key role in tackling climate change. Available sources of renewable energy in pennsylvania include solar geothermal wind hydropower and biomass. Electricity generation air and water heating cooling transportation and rural off grid energy services.

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. 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. 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 pv panels are what you may see on the roof of someone s house.

Renewable energy often provides energy in four important areas. People have been putting wind energy to use throughout history to propel sail boats mill flour from grain and pump water. Renewable energy usable energy derived from replenishable sources such as the sun solar energy wind wind power rivers hydroelectric power hot springs geothermal energy tides tidal power and biomass biofuels. Solar wind hydropower and other renewable energy sources currently account for a small share of global energy.

Nearly a third of the earth s electricity will come from renewables by 2024 according to the international energy agency. Solar is the conversion of sunlight into electricity by either solar photovoltaic pv panels or solar thermal systems. Wind is the lowest cost large scale renewable energy source while rooftop solar panels are competitive with retail electricity prices. For example sunlight or wind keep shining and blowing even if their.

Clean energy has far more to recommend it.
