Since taking over as CEO of Green Mountain Power, she's implemented a startup culture that represents a dramatic departure from a traditional utility model -- obsessing over the customer, mixing employees in order to uncover new ideas, testing out new products and re-imagining the power delivery business model itself.

And we could use wind, solar and storage to cost-effectively cut grid emissions in half. But to go from 50 percent reductions to 100 percent -- that will take a much more diverse range of technologies. That is the conclusion of a new literature review of 30...

It’s been 15 years since Cape Wind -- the project meant to be America’s first offshore wind farm -- was first proposed. For years, the 130-turbine, 450-megawatt project was held up as the start of an entirely new industry in the U.S. But fierce legal opposition and project financing problems eventually brought the project down.
