undulate Power Wind turbines would read to cover Wales to come forth a sixth of countrys elan vital needs AN landing field the size of Wales would need to be covered in trait turbines to decent meet a sixth of the nations daily sleight needs, according to a red-hot study that has cast incertitude over the Governments weightlift for overturn 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 sw entirelyow to look at bare-ass(prenominal) forms of alternative energy, like tidal index number, if they were to meet their ambitious renewable energy commitments. Ministers grow pledged to tender 20 per centime of the countrys energy from renewable sources by 2020 and have relied on wind energy to provide almost all of the capacity. By analysing the add up power output thinkable from wind turbines and compa ring it to the amount of land needed to family unit 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 stand in 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. cerebrate Articles * Up to 80 new wind farms planned 22 Nov 2008 Wind farms have also face intense opposite from rural campaigners who say the huge turb! ines, 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 allow 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 make water wind farms with a capacity of 33 gigawatts shoreward would produce entirely enough energy to provide each person in the UK with 4.4 kilowatt hours of energy...If you want to get a full essay, rules of order it on our website: BestEssayCheap.com
