Al Gore’s commitment to promoting green energy has brought him widespread acclaim, a Nobel Prize and even an Oscar. It’s also brought him more than a pretty penny.

The author of An Inconvenient Truth has swelled his net worth to about $100 million, largely due to his investments in green energy, after being worth less than $2 million during his time as Vice President, The Washington Post reports.

That's big money for the lifelong devotee of environmental responsibility, who in his last year as Vice President only garnered a $181,400 salary. Even the film version of "An Inconvenient Truth," despite being among the top-ten highest grossing documentaries of all time, netted much less than Al Gore earned through investments.

For more on Al Gore's investments in green energy read the full WaPo article..

Gore isn’t the only one who’s betting on green energy. The United States invested $51 billion in renewable energy in 2011 , second only to China in a year where green investments hit a record high.

He also has to thank the Obama administration's 2009 stimulus package. The $80 to $90 billion worth of government investment in green energy has helped to grow many of the companies Gore and his renewable energy-based hedge fund Generation Investment Management have put the majority of their money in. In fact, nine of 11 companies that Gore endorsed during a 2008 presentation on fighting climate change received government investment, WaPo reports.

Few will need reminding, however, that not all investments in green energy turn out to be as sustainable as the technology those dollars hope to bring about. Bankrupt solar energy company Solyndra is one of the primary examples of renewable energy investment gone wrong after the company failed despite a $527 million loan from the U.S. government.

But the success rate of renewable energy companies may be far higher than some, particularly Presidential candidate Mitt Romney, would like to admit. During the first Presidential debate, Romney claimed that over half the green energy companies benefitting from stimulus dollars failed. In fact, just 1.4 percent of the U.S. dollars invested in green energy went to companies that had failed by the end of 2011, CleanTechnica reports.

  • Myth: The amount of cash available has grown tremendously.

    <a href="http://www.nytimes.com/2011/02/10/business/economy/10fed.html?_r=1">Some Federal Reserve critics claim</a> that the Fed has devalued the U.S. dollar through a massive expansion of the amount of currency in circulation.

  • Myth: The Fed can't easily unwind all of this stimulus.

    <a href="http://www.salon.com/2012/09/01/ben_bernanke_speaks//">Some commentators</a> <a href="http://seekingalpha.com/article/161203-fed-unwinding-won-t-be-easy">have claimed</a> that the Fed can't safely unwind its quantitative easing measures. But the Fed's program involves buying some of the most heavily traded and owned securities in the world, Treasury and government-backed mortgage bonds. The Fed will likely have little problem finding buyers for these securities, all of which will eventually expire even if the Fed does nothing. But <a href="http://economistsview.typepad.com/timduy/2012/09/plosser-opposes-the-1933-37-expansion.html">economists have noted</a> that once the Fed decides it's time to unwind the stimulus, the economy will have improved to such an extent that this won't be an issue.
