Global wind energy capacity to double over five years
...Most of the growth would come from Latin America, Africa, India, China and the rest of Asia. In terms of cumulative wind capacity, while Europe had been ahead for some time, Sawyer said it was predicted that by 2016, Asia would have overtaken Europe as the leader in this regard.
Optimistic models predicted that by 2020, there would be 1 071 GW of installed wind power globally and 2 342 GW by 2030. However, more moderate models predicted 832 GW in 2020, and 1 778 GW in 2030.
Substantial growth was forecast for 2012, but policy uncertainty in the US is weighing on next year’s outlook, Sawyer said.
The biggest challenge facing the wind energy sector continued to be the perception that wind was more expensive than coal. According to a 2010 study in North America, the general perception by government officials and media was that installing wind capacity was four times more expensive than building coal plants, but the study showed that in the same year, the cost of building new wind energy projects was in reality on a level with those of coal.
“Ten, five years ago everybody said renewables are just too expensive. . . Every situation is different but on the whole, as a general statement, that is just no longer true. And that not only goes for wind but it also goes for solar [photovoltaic] and we have to combat that at every available opportunity,” said Sawyer. (CLICK THE LINK ABOVE TO CONTINUE)
