As before, we have put together a long list of prospective candidates in four different fields — manufacturing, policy, finance and development. Readers can vote for who they judge to be the most powerful.
Last year the first seven places went to the chief executives of the industry's leading manufacturers, with GE's Anne McEntee topping the poll. But this could be the year that policy makers come to the fore with minds concentrated on the COP21 UN climate change talks in Paris in December.
The rise of yieldcos in North America, and the growing importance of outside investors to fund large, complex projects are also reflected in this year's long list.
The voting will be open for one week.
