According to a recently published report by Peachtree Capital Advisors, a New York-based investment bank, investors loved renewable energy in2010. The report notes that the wind industry closed the year at $4.8 billion in transaction value while solar finished at $.3.2 billion. Not to be forgotten, smart grid and LED lighting companies closed at $2.5 billion.

As far as 2010 investments in cleantech companies went in 2010, energy-efficiency start-ups closed the most deals with venture capitalists (VCs). But it was actually solar energy start-ups that saw the most VC money. As for wind? It’s a more mature market with a greater number of companies already well-positioned, meaning there was less room for start-ups to move in to the sector.

So what does all this fancy finance talk mean for the future of clean energy? It means that investors — most of which spend their time dissecting  scores of markets in order to find wise investment — see a great upside in renewable energy. And as long they keep investing, the industry will keep moving forward.
