One large turbine has fewer moving parts than ten smaller turbines. The mechanic can work in relative safety inside a larger turbine. It creates a local noise problem. There have been problems with raptor kills. Studies have shown these problems can be minimized with properly designed towers and blades.
All vegetation is produced by the sun.
All animal life is dependent on vegetation and therefore on the sun. Burning wood or garbage to create energy is a form of biomass conversion. Creating Methane, Ethanol or other fuels from vegetation is a form of biomass conversion. It should be noted that oil and coal are also forms of solar energy. Plants and animals which used the sun's energy to grow and create biomass died long ago and were transformed over long periods of time under great pressure into oil and coal.
