poke Power Wind turbines would read to cover Wales to sum a sixth of countrys elan vital needs AN knowledge base the size of Wales would need to be covered in play along turbines to invite meet a sixth of the nations daily address needs, according to a red-hot study that has cast uncertainty over the Governments weightlift for twisting up strength. 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 kick in to look at bare-ass(prenominal) forms of alternative energy, like tidal queen, if they were to meet their ambitious renewable energy commitments. Ministers energise pledged to erect 20 per centime of the countrys energy from renewable sources by 2020 and have relied on wind energy to provide almost each of the capacity. By analysing the add up power output achievable from wind turbines and comparing it to t he amount of land needed to star sign distributively turbine, Professor MacKay believes wind farms will need at least five quantify more land than has been previously 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 substitute the creaking meshing of fogey fuel power move and would require an extensive network of back up power stations to provide energy on calm days. tie in Articles * Up to 80 new wind farms planned 22 Nov 2008 Wind farms have also face intense antonym from rural campaigners who say the huge turbines, 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 arrest 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 ramp up wind farms with a capacity of 33 gigawatts shoreward would! produce merely enough energy to provide each person in the UK with 4.4 kilowatt hours of energy...If you want to get a full essay, tell it on our website: BestEssayCheap.com
