What is the short term future of Alternative Energy?

We all know we need alternative energy solutions in the next decade. However, I am wondering what the impact of energy price reductions are on current investments in alternative energy. Is this going to cause companies to stomp on the brakes in this category until we get a rally in energy prices to the $70 - $90/ bbl range?? I think so, but looking for your view.
