(Phys.org) -- A study conducted by researchers from the ETH and Empa has come to the conclusion that large sized wind turbines produce "greener" electric power than small ones. Environmental benefits have also accrued as wind turbine producers gain experience and learn from each other. The developers of life-cycle analyses have also profited from the experience of the last 30 years of wind generator usage because this allows them to fine tune their techniques, enabling them to better estimate the effects of new technologies over large timespans.
