Wind farms generate electricity using the power of the wind. There are no polluting carbon dioxide (CO2) emissions, such as are released from fossil fuels (coal, oil and natural gas).
Those aspects of human health and diseases that are determined by the factors in the environment that guarantee the proper fate of future generations are called environmental health....
Your carbon footprint builds up as you become responsible for more carbon dioxide emissions. You can do this by buying a bigger car, or by using your air conditioning, or by driving to work instead of taking public transport. You can build it up even by eating more red meat!
Electrons absorb energy to make electrons move from an lower energy level to a higher energy level. This energy is released as some form of e-m radiation when the electron moves from the higher level to a lower energy level.
Carbon Dioxide is the primary one. It is made by burning fossil fuels. Methane is also a result of human agricultural practices. Chlorofluorocarbons are released in some manufacturing processes, though in recent years there have been much tighter international controls on CFC emissions.
