Yesterday we published a list of 18 hot solar startups that you don’t see in all the headlines.
Today we are expanding on the energy theme with a 17 hot wind, biofuel and oceans-energy companies. They come from the Cleantech 100 list of privately held firms selected for their potential to grow quickly.

Wave farm developer Pelamis made the Cleantech 100 list
The list was compiled and released earlier this week by the Cleantech Group and the Guardian, publishers of the Guardian newspaper in Britain.
Today’s list includes three winds companies, two marine-energy firms and 12 businesses involved with biofuels. Eleven are from the U.S., five make their homes in Europe and one is Israeli.
The Cleantech 100 includes companies in eight other market segments, and we will publish their names in coming days. Overall, there are 55 startups from the United States, 13 from the United Kingdom, 10 from Germany, five from Israel and three from India. No Chinese companies made the list.
