Wind could meet world power demand by 2013, say Stanford researchers
By Andrew Myers (*) Adapting a sophisticated climate model, researchers show that there is plenty of wind available to supply half to several times the world's total energy needs within the next two decades. Read full article

Sep 12th, 2012 - 06:47 am - Link - Report abuse 0The text says by 2030, but what a nonsense paper this is. How do scientists get funding for such crazy research?
“Today, we have installed a little over 1 percent of the wind power needed,” Jacobson said.”
“Jacobson and Archer would site half of the 4 million turbines over water. The remaining 2 million would require a little more than one-half of 1 percent of the Earth's land surface.”
So how is the power to get from these turbines to where people live and what about all the the base load power stations that would need to be built, plus grids cannot cope with more than around 8% from wind before they fail.
“Their model assumed wind turbines could be installed anywhere and everywhere, without regard to societal, environmental, climatic or economic considerations.”
Quite. So what value is this?
@1 I think I've found a purpose for argieland. We could carpet the whole place with turbines. It's not serving any useful purpose at the moment.
Sep 12th, 2012 - 11:35 am - Link - Report abuse 0There is to much wind coming from some argie bloggers , now,
Sep 12th, 2012 - 12:18 pm - Link - Report abuse 0Perhaps its what they do,
Still,
If a blow jobs worth doing,
Then you might as well blow properly.
Just don’t regurgitate at the same time .lol..
I guess if the wind blew consistently and at all times we could replace all other sources of energy.
Sep 12th, 2012 - 02:21 pm - Link - Report abuse 0Unfortunately, the 10% rule tells us that the over-provision needs to be some x10 to ensure there is sufficient electrical energy everywhere at all times. So 4 million mega-turbines (100m high) translates into 40 million, half of these along the coast.
There are 356,000 Km (221208 miles) of coastline, with 'fractal complexity'.
There would be 56 giant wind turbines per mile .... 30 yards apart, ie touching tips ... along every mile of shoreline in the world.
Some countries have long coastlines; [top 10: Canada (125,567 miles), Indonesia (33,998), Russia (23,397), The Philippines (22,549), Japan (18,486), Australia (16,006), Norway (15,626), United States (12,380), New Zealand (9,404), China (9,010)];
some countries are small and have no coastline at all.
A world-wide electricity grid would be some grid!
Some nations would be nett sellers and some would be nett buyers of 'World Electricity'. Canada with a 'low' population, high wind energies and long coastlines would be theoretically very rich indeed!
The key word is 'theoretical'. Mathematical models and calculations are all very well, but we live in the real world with mixed (alternative) energy economies.
My Environmental Science students used to like this end-of-first year seminar, and, at its conclusion, would then step out into the open air with the sun beating down its summer energy onto them.
think most “scientists” or people feeding info into a computer,are acid heads
Sep 12th, 2012 - 04:25 pm - Link - Report abuse 0cause they have beautiful experiences with little reality involved.end of.
Excellent plan for action, now lets get on and do it
