All the talk resonating through the Congress and the White House about energy efficiency, clean energy investments and green jobs begs the following question: Exactly where is the money going to come from?
Probably not via the cap-and-trade plans circulating in the House and Senate, which focus on curbing carbon emissions and forcing utilities to draw on more existing renewable energy sources. And likely not from the credit markets, which are only functioning these days thanks to massive intervention by the Federal Reserve.
For all their social utility, next-generation energy projects are a somewhat risky investment because of fluctuating fossil fuel prices, an incomplete national transmission grid and the lack of a proven track record for the technologies involved. The government can offer loan guarantees and tax credits to reduce some of the risk, but those incentives are always subject to the whims of Congress.
Which is why there is an intensifying push to create a so-called Green Bank, which would provide a dedicated source of funds for renewable and energy efficient initiatives.
