Vast amount of clean energy can be generated via wind turbines and supply more than enough of what the entire planet needs, reports said.
Yet to realise such a gigantic undertaking, large scale of money and engineering efforts must be poured on global projects that would dramatically multiply the world's existing wind farms, The Associated Press (AP) reported on Tuesday citing the findings of two new U.S. studies.
The scientific studies authored separately by Ken Caldeira and Mark Jacobson pointed to the likelihood that wind turbine farms could harness enough energy to feed all the power-hungry nations.
While the two studies, recently published in the journals Nature Climate Change and the Proceedings of the National Academy of Sciences, clash on the quantity of energy that wind turbines could potentially create, both agreed on concluding that the amount should far exceed what the world consumes at the moment.
Mr Jacobson of the Stanford University in California is convinced that if operational wind farms in the world would be increased by at least a hundred times, these turbines could collectively provide the overall energy requirements of man, and probably more.
Too bad, he added, the world's quest for alternative energy source is currently geared heavily on nurturing the further development of natural gas, taking away the investments needed to fire up what his study termed as the stalled wind turbine industry.
Mr Caldeira of the Carnegie Institution for Science, also in California, is upbeat on the potential of wind turbine farms, which he asserted would boost the world's energy stocks by at least 20 per cent.
In fact, he sees no limit at all on how dependable wind turbines could be provided there would be enough of them in strategic locations around the world.
"It's really a question about economics and engineering and not a question of fundamental resource availability," Mr Caldeira was quoted by AP as saying in his report.
Critics, however, scored the new studies for ignoring the hard realities of economics.
Wind farms with the present technology governing their structures and functions, critics said, would not be able to attract the money needed because of uncertain investment return scenario with such projects.
Literally, the world will be covered with wind turbines just so to realise the imagery painted by the studies of Mr Jacobson and Mr Caldeira, Jerry Taylor of Cato Institute told AP.
