Whilst the energy grids we rely on to provide us with cheap and reliable electricity may have been fit for purpose in the 20th century, it is now abundantly clear that the design of 21st century energy networks will have to be very different. In Europe, the foundations for a secure, flexible and more energy efficient future are already being laid.
David Crane is a man who isn't afraid of a challenge. When he took the helm at NRG Energy in the winter of 2003, the company was mired in Chapter 11 bankruptcy proceedings -- just one of many companies caught in the meltdown of the U.S. power generation industry, instigated by the scandalous collapse of Texan power giant Enron in 2001.
Sandwiched between two nondescript commercial buildings in a vacant lot squats what looks like a long, plastic-shrouded greenhouse. Hanging nearby is a cluster of five-foot-long plastic sacks bulging with green slime that resemble intravenous drip bags for the Jolly Green Giant. It doesn't look like groundbreaking technology, but these scum bags in Cambridge, Mass., just might help save the planet.
Halfway around the world, a zero-carbon, zero-waste, automobile-free city known as Masdar is rising from a 2.3-square mile plot of desert in Abu Dhabi.
Whisky is for drinkin', water is for fightin'.
NRG Energy's David Crane can seem miscast sometimes in the role of a Fortune 500 CEO. He wears a child's blue Swatch with a shiny plastic band. He settles into a chair - even a boardroom chair - the way a teenager would, with one leg curled up under his body.
Widespread anxiety about the damaging effects of burning fossil fuels, coupled with a genuine fear that oil and gas will become scarce before the century ends are fueling a renewed interest in renewable energy and, in particular, solar power solutions.
The proliferation of coal-burning power plants around the world may pose "the single greatest challenge" to averting dangerous climate change, an international panel of scientists have reported.
Georgia Gov. Sonny Perdue declared a water supply emergency in north Georgia on Saturday as its water resources dwindled to a dangerously low level after months of drought.
If you've read our story on Macquarie Bank you know that - regardless of that company's prospects - investors see plenty of opportunities in infrastructure.

For a long time, conventional wisdom has held that coal would easily meet the nation's rising demand for electricity. It's cheap, and there's enough of it in the U.S. to power the country for an estimated 250 years.
Joel Rheault ducks beneath the steel door of the elevator cage and steps into a freezing rainstorm -- 1,600 feet below ground, at the mouth of a cavernous concrete tunnel. Wind whips the water dripping from his hard hat as Rheault switches on his headlamp, climbs into a Toyota Land Cruiser that's been parked underground, and drives off into the darkness.
"We were at heightened security - we were at red," recalls Al Griffith, spokesman for the utility that owns the Seabrook Nuclear Power Plant in New Hampshire.
As the summer swelters on, skyscrapers and apartments around the city will crank up air conditioners and push the city's power grid to the limit -- but some have found a cool alternative
MAKING ELECTRICITY IS A DIRTY BUSINESS. Just take a peek inside the boiler at your typical power plant. Fueled by crushed coal, a fireball howls and burns at 2,500° Fahrenheit, hot enough to melt iron. A ghostly snow of ash drifts down around the fire until it hits a pipe or a ridge. There it piles up, melts and hardens into slag, which reduces the boiler's efficiency. Removing the slag is costly, time consuming, and dangerous. Slag formations can grow to the size of a small car and weigh several tons. Some workers have used shotguns to try to blast the stuff off the boiler; others have used jackhammers. Neither method works very well. For decades, slag has been the nightmare of the utility industry.

The Bush administration Tuesday applauded a Russian ultimatum to Iran that it will not supply fuel for Iran's Bushehr nuclear power plant until Iran agrees to suspend uranium enrichment.
Most people don't spend an hour gabbing on their cell phone in the middle of the day. It's just too expensive.
Big lumps of sooty coal hardly seem like the future of energy, but that's exactly what the U.S. Department of Energy predicts. Consumption of the fossil fuel --the main source of greenhouse gas and a major contributor to acid rain, smog and mercury poisoning --will hit 10.6 billion tons a year by 2030, a near doubling of the 5.4 billion tons burned in 2003, according to the agency.
The planet's most pressing environmental problems—global warming, energy shortages, overfishing, pollution—may seem just too big to be solved with today's technology. But don't despair: A lot of br...

As the U.S. Supreme Court prepares to take up the issue of climate change, some unusual alliances are forming - and corporate America finds itself on both sides of the debate.
While the U.S. hems and haws over reviving nuclear energy as a less expensive alternative to oil, Russia has dug back 30 years in our nuclear history to find a solution for some of its own energy woes: the floating nuclear power plant.
Rattling down a red dirt road on the edge of the Australian outback, Roger Davey hits the brakes and hops out of a rented Corolla. With a sweep of his arm, he surveys his domain - 24,000 acres of e...

Dean Kamen, the engineer who invented the Segway, is puzzling over a new equation these days. An estimated 1.1 billion people in the world don't have access to clean drinking water, and an estimated 1.6 billion don't have electricity. Those figures add up to a big problem for the world--and an equally big opportunity for entrepreneurs.
