The smart grid will save energy and money, but implementation may prove costly
A nut-and-bolts, transformer-and-cable view of the power grid as it gets smarter
Improving turbines, which lie at the core of a modern power grid, is all about standing up to the heat
The grid's flow of data is supposed to improve energy delivery but must be protected from hackers' prying eyes
Utilities are spending billions to make the grid more reliable, efficient, and green
Geothermal, solar thermal, and even nuclear power could provide alternatives to today's carbon-based fuel sources
The U.S.--and the world--is gearing up to build a potentially massive fleet of new nuclear reactors, in part to fight climate change. But can nuclear power handle the load?
The world's first power facility to capture and store a portion of its carbon dioxide has begun operating in Appalachia
The new economic stimulus package set aside $11 billion in federal funding for creation of a so-called "smart grid." But it's not clear what this national electricity delivery system will look like, how it will function or who will manage the information required to make the grid intelligent.
Federal investment in entrepreneurs will create jobs, boost the economy and raise energy security
Tougher regulatory measures are in place, but we're still a long way from a "smart" power grid
With $610 million in economic stimulus money added to his budget, Patrick Gallagher is preparing the nation's standards and measures agency for prime time
One small island in Denmark is technically 100 percent powered by sustainable sources of energy. Could the experiment succeed anywhere else?
CAMBRIDGE, MASS.—By 2030, the people of the world will be driving as many as two billion cars—up from 700 million today—according to John Viera, director of sustainable business strategies for Ford Motor Company.
If you're still clutching your chest over that last sky-high electric bill and wondering how to keep it down next month, you'll be heartened to hear that help may be on the way from the company behind the world's largest search engine.
Simply using instead of losing energy, the U.S.--and the world--could power its way out of crisis. David Biello reports
The standard for plugging electric cars and hybrids into utility meters remains undefined
The U.S. electric grid is so old and outdated it can't handle the influx of wind power and other intermittent renewable resources. Integrating such sources requires adapting a system that is finely tuned to balance the amount of electricity being used with the amount of electricity being generated with fickle winds.
A smarter power grid that automatically responds to problems could reduce the rising number of debilitating blackouts
