With 11 newcomers - several of them American expats gone to Europe - our list of the most powerful women in global business demonstrates their rise in male-dominated fields, from nuclear energy to mining to oil.

16. Vivienne Cox
EVP, Gas, Power, and Renewables
BP
Country: Britain
2006 rank:  15

The Oxford-trained chemist's credentials are high octane - a career that spans 30 years at BP and includes stints at the exploration and finance divisions. One of Cox's challenges is to lead the company's clean- and alternative-energy movement. And though 2006 saw just a 3% profit increase, she recently worked out a deal with Rio Tinto, where she's a board member, to develop zero-emission coal technologies.
