Denmark is leading the wind power race. And they’re doing a little too well. Denmark gets about 20% of its total electrical power from wind, and on more blustery days, that percentage can double, putting a strain on their electricity grids. And although this may not seem like a problem for us consumers, on a windy day the price of electricity can drop to zero, putting utility companies in a tough spot as they try to offload excess power.

To offset these loses, Dong Energy, a Danish utility company has found a way to utilize this excess wind power. The company, one of Northern Europe’s leading energy groups, has plans to build a nationwide system to charge electric cars with the surplus wind power. Partnering with a California-based company, a time-line has been put in place to have the infrastructure to support a country-wide electric car system by 2010.

Denmark has built stronger connections to nearby Germany, Sweden and Norway so it can sell excess electricity on windy days. When it blows in Denmark for example, Norway buy cheap power to supplement their own hydropower resources.

“We have to keep investing heavily in the grid to make sure we can transport the electricity from wind when and where it is most needed,” said Peter Jorgensen, vice president of the state-owned company that runs Denmark’s grid.

Barack Obama is now officially the 44th President of the United States.

“Today I say to you that the challenges we face are real,” Obama said in his inaugural speech. “They are serious and they are many. They will not be met easily or in a short span of time. But know this, America — they will be met.”

Over 1.4 million people crowded onto the National Mall to watch Obama become America’s first black president.  The overwhelming supoprt for Obama, who currently holds an 80 percent approval rating, is primarily due to America’s distaste for Bush, who has left office with the lowest ratings in presidential history.

Obama has just taken the weight of the multiple woes of American (and much of the world) upon his shoulders, and has pledged to do his best to help curb the economic crises and bring an end to the war in Iraq.

Obama also has plans to turn to renewable energy for the clean technology sector, planning to add 20 gigawatts or more of wind power by 2012. Welcome, Barack Obama!

The Greenbird is part aeroplane, part sailboat, part Formula One car, which runs on the harnessed power of wind. A U.K. company with hopes for a zero carbon transportation future, has engineered a land craft and ice craft, powered only by the wind.

The solid, carbon-fibre sails provide thrust, while the design enables the land craft to travel at between 3 to 5 times the real wind speed, depending on the surface traction. This wind-powered car recently clocked 60 mph during a preliminary speed trial in the Australian desert.

If you’re thinking about cruising the strip in this puppy though - think again. The car is developed for speed and novelty, not necessarily designed for the mainstream market. For cars you can be seen in, check out these eco-friendly vehicles.
