Solar Roadways Could Solve The US Energy Crisis
The benefits to their solar powered roadway go beyond the conventional. In addition to generating electricity, the solar road ways, which are crafted of solar cells and glass, contain LEDs that could provide drivers with information similar today’s overhead highway signs as well as melt snow and ice using built-in heating elements.
Solar Roadways Receives DOT Contract
A visionary project, called Solar Roadways, announced that it has been awarded a $100,000 Department of Transportation contract to build a prototype road "paved" with solar panels.

Alternative Energy
Scavenging Energy from Evaporation
According to NewScientist: “The researchers added metal plates to the walls of the central stem and connected them to a circuit. The charged plates and the water within the stem create a sandwich of two conducting layers separated by an insulating layer – in effect, a capacitor.”
Future Uses of Solar Energy
According to the U.S. Department of Energy’s Energy Efficiency and Renewable Energy arm, there will be more breakthroughs in new materials, cell designs, and novel approaches to product development in photovoltaic research and development. Future uses of solar energy could include our mode of transportation and even clothing, which will be equipped to produce clean, safe electric power.
Ambitious green targets boost renewable energy
Fund managers say this increased commitment, together with a similar focus from the US, plus stronger moves towards clean energy from China, is welcome news for an industry that has been slow to take off – and has suffered more than others in the recent downturn.

Bowing In The Wind?
How Does a Wind Turbine Work?
Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.
Small wind turbines blow out big sales
Sales of turbines big enough to serve a single home or office building grew rapidly last year and are poised for even faster growth this year, according to a report from the American Wind Energy Association
Home Wind Turbines Are A Worthless, Dangerous, Wasteful Vanity
This writer just looked at the wattage on a newly purchased Revlon brand hairdryer: Rating was 1985W. That's roughly equivalent to twenty, 100-W incandescant bulbs...surely more than a whole residence-worth of what's actually lit at any one time... or to over one hundred forty (14W-rated, 60W incandescant equivalent) compact flourescent bulbs.
More States Offer Rebates for Home Wind Turbines
Altogether, says Mr. Stimmel, some kind of financial incentive for residential small wind is available in about 17 states, though in some cases the incentives are offered through utilities rather than directly by the state itself.

The Future Of Energy
Power to the People: 7 Ways to Fix the Grid, Now
Now consider what we will ask the grid to handle in the near future: Demand for electricity is expected to increase by as much as 40 percent in the next two decades—more than twice the population growth rate. To meet that need, we will have to generate an additional 214 gigawatts, a feat that would require the construction of more than 357 large coal plants. We also want to plug in dozens, if not hundreds, of gigawatts of wind and solar power harvested from the most remote corners of the country. And we will want to recharge millions of electric vehicles every night, without fail.
Subsidies For Alternative Energy Costs Less Than Subsidies For Traditional Energy
The perpetual knock made against renewable energies like wind and solar is that they couldn't exist with out government subsidies. However, upon close inspection, it looks like all energy relies on healthy amount of support from the government.
New Material Could Help Cut Future Energy Losses
The team have produced a material from a football-shaped molecule, called carbon60, to demonstrate how a superconductor – an element, compound or alloy that does not oppose the steady passage of an electric current – could work at temperatures suitable for commercial use in cities and towns.
