Wind power does not reduce CO2 emissions as much as claimed
“The assertion that wind turbines don’t reduce carbon emissions is a myth, according to conclusive statistical data obtained from National Grid and analysed here in the Guardian for the first time,” Chris Goodall and Mark Lynas claimed in a recent Guardian blog. Professor Gordon Hughes responds: 1. It is unfortunate that the polarisation of positions renewable energy has coarsened arguments about the impact of wind and solar power on electricity systems. This has been apparent in a series of postings . . . Complete article »
Why is wind power so expensive?
Summary 1. Wind power is a capital-intensive means of generating electricity. as such, it competes with electricity generated by nuclear or coal-fired generating plants (with or without carbon capture). However, because wind power is intermittent, the management of electricity systems becomes increasingly difficult if the share of wind power in total system capacity approaches or exceeds the minimum level of demand during the year (base load). It is expensive and inefficient to run large nuclear or coal plants so that . . . Complete article »
