The Burbo Bank Wind Farm, Liverpool Photo: GETTY By Richard gray-haired 2:39PM GMT 22 Nov 2008 7 Comments Professor David MacKay, a physicist at Cambridge University, said ministers would score to look at bare-ass(prenominal) forms of alternative energy, like tidal designer, if they were to meet their ambitious renewable energy commitments. Ministers have got pledged to translate 20 per centime of the countrys energy from renewable sources by 2020 and have relied on wind energy to provide almost wholly of the capacity. By analysing the add up power output thinkable from wind turbines and compar ing it to the amount of land needed to fellowship distributively turbine, Professor MacKay believes wind farms will need at least five quantify more land than has been antecedently estimated. His research has raised farther doubts over the viability of the Governments push for wind power.

Critics insist that wind energy is too unreliable to set back the creaking meshing of fogey fuel power place and would require an extensive network of back up power stations to provide energy on calm days. related to Articles * Up to 80 new wind farms planned 22 Nov 2008 Wind farms have also face intense ambition from rural campaigners who say the huge tur! bines, which tidy sum be up to 400 feet tall, are spoiling the countryside and sire a risk to wildlife. Professor MacKay, who has published a new control that examines a range of different renewable energy sources, insists he is a strong supporter of wind energy. His calculations show, however, that flow plans to defecate wind farms with a capacity of 33 gigawatts shoreward would produce but enough energy to provide each person in the UK with 4.4 kilowatt hours of energy...If you want to get a full essay, put up it on our website: BestEssayCheap.com
