We don’t need nuclear power, coal, or biofuels. We can get 100 percent of our energy from wind, water, and solar (WWS) power. And we can do it today—efficiently, reliably, safely, sustainably, and economically.

We can get to this WWS world by simply building a lot of new systems for the production, transmission, and use of energy. One scenario that Stanford engineering professor Mark Jacobson and I developed, projecting to 2030, includes:

Providing clean, renewable energy to the 1.4 billion people who are living without electricity is the No. 1 priority of the United Nations, the secretary general of the U.N. said during a visit Aug. 24 to the U.S. Department of Energy's National Renewable Energy Laboratory.

NEW YORK--(EON: Enhanced Online News)--New research from Bloomberg New Energy Finance reveals that despite many platitudes and pledges, governments of the world are spending substantially more on subsidizing dirty forms of energy than on renewables and biofuels. In fact, support for cleaner sources is dwarfed by the help the oil, coal, and other fossil fuel sectors receive.

There is a new tool sharpening California's renewable vision. It is in the form of a state-of-the-art system control center that houses the first dedicated renewables dispatch facility in the nation. As the state approaches a goal of generating 20 percent of its power from renewable resources, which escalates to an ambitious 33 percent by 2020, ensuring reliability brings new meaning to California grid operations.
