We do use way to much oil & need alternatives but the big problem right now is Investors driving up the prices by trading so heavly in the futures market. Greed is destroying the planet faster than all the polution & waste combined.
To answer your question
How many solar panels and wind mills will it take to replace 87 million barrels of oil a dayMore than we have the global capicity or resources to manufacture.
In a report, which was produced at the request of Congress, the U.S. Department of Interior's Bureau of Land Management (BLM), said there are 279 million acres under federal management where oil and gas could potentially could be extracted.
More than half of it is totally off-limits to drillers.
"The total onshore resource is 31 billion barrels," said BLM's lead scientist Richard Watson, who authored the report. "Of that, 19 billion barrels are currently inaccessible or 62 percent. A little over 2 billion barrels, or 8 percent, is accessible under what we call standard lease terms."
If you add in the 85.9 billion barrels of oil that lie offshore, as determined by the Interior Department's Minerals Management Service, there are 117 billion barrels of oil on lands owned or managed by the U.S. government.
But all expansion of offshore oil recovery is currently off-limits.
Adding in what's available on privately held land, the figure rises to 139 billion barrels of oil, according to the government - more than the known oil reserves of Iran, Iraq, Russia, Nigeria or Venezuela, respectively.
