Lynda Clemmons, VP of sustainable solutions at NRG, on transformative energy generation

"Our customers want things to be simple. Everybody wants to meet their sustainability goals. They want to do the right thing ... in a clean and green way," said Lynda Clemmons, vice president of sustainable solutions at NRG Energy, the U.S.integratedpower company.

The company is working a new project called "Renewable Select" thatcombines generation and retail to bring the choice of renewables to customers who want it, but might not have as large a purchasing power as the Googles and the Microsofts, as Clemmons noted.

The growth of renewables means the growth of clean power, but also consumer choice.
