LOW ROLLING RESISTANCE TIRES
Only about 12 to 20 percent of the energy produced by the engine actually turns the wheels, and about one-third of that is consumed by rolling resistance. As you drive down the road, your tires squirm and deform every time you go around a corner, accelerate, or apply the brakes. The repeated tire deformation between the tire and the road, within the tire and between the tire and the rim, causes mechanical energy to be converted to heat; hence additional mechanical energy must be supplied to drive the axle.

NREL REPORT - CONSUMERS AND GREEN POWER
The U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) today released its annual assessment of leading utility green power programs. Under these voluntary programs, consumers can choose to help support additional electricity production from renewable resources such as wind and solar.
SEMANTIC SEARCH REIGNITES HYDROGEN FUEL RESEARCH
The Obama administration has made alternative fuel research a key objective for the country. Researchers in the area of hydrogen fuel cell research therefore are faced with a plethora of peer reviewed publications that they must read to stay abreast of not only the latest publications but also historical publications that may be relevant to a current discovery.

THE ROAD TO ENERGY SELF SUFFICIENCY
Have you ever bought a lottery ticket? Everybody loves a good contest. Let's have a national contest to devise a solution for our energy problem. If this plan is launched there will be innumerable business plans being word processed before the next dawn. Can you imagine having the patent on the replacement for oil? How valuable would that be, tax free? As a spin off value of this contest, can you imagine having the patent to create a new source of water, and be able to sell it to the drought stricken Mid East and Africa, and have the profits being tax free for ten years? How valuable would that be? How many people / companies would be lining up to participate?
TIDAL WAVE INDUSTRY ANALYSIS
While the wave energy industry is still in its infancy phase of development, America and the rest of the world are realizing the catastrophic effects of the oil industry's grip upon the global economy. We look at hydrogen and solar energy as viable alternatives to oil. In addition, tidal wave energy is a phenomenon that should be seriously considered as a viable form of energy for people to power their homes, cars, and boats.
Largest Solar Array in Southeast
Orange County Convention Center's new one-megawatt photovoltaic (PV) system , the largest rooftop solar installation in the Southeast. Solar panels will span the length of five and a half football fields, generating 1,300 megawatt-hours of electricity per year - greatly reducing the center's carbon footprint and electricity costs. The unveiling will kick off the Green Cities Florida Conference, a two-day event providing fresh, innovative and useful information to businesses, communities and governments interested in embarking on the road to sustainability or improving their current efforts.
EUROPE'S LARGEST ONSHORE WINDFARM COMING ONLINE
Scotland's Whitelee windfarm has a capacity of 322MW, enough to power 180,000 homes, or a city the size of Glasgow. The opening celebration was enhanced by the news of the Scottish Government's approval for an extension, which will raise the windfarm's power capacity to 452MW and create 300 much-needed green jobs in construction. Whitelee takes the current level of wind operating up to 3.5GW. A further 9.2GW is either under construction or about to start construction, but 8.6GW, of which 7.1GW is onshore, is still awaiting planning permission. In England and Wales the majority of this is onshore at Local Government level, where planning decisions can take up to two years to be made, and the approval rate is only 40%.
Semiconductors Save Money and Energy --- Big Time
Semiconductor technologies, present in many modern day devices and systems, are so essential to advances in energy efficiency gains that the United States economy could expand by more than 70 percent through 2030 and still use 11 percent less electricity than it did in 2008, according to a new study by the American Council for an Energy-Efficient Economy (ACEEE). The report estimates the cumulative net electricity bill savings enabled by semiconductors might exceed $1.2 trillion through 2030. With smart investments productivity gains could reduce electricity use to only 3,364 billion kWh by 2030. The resulting savings of 1,242 billion kWh means that the economy may actually consume 11 percent less electricity in 2030 than it did in 2008. Original Metering.com article.
Gravel Stores Energy for the Grid
A group of English engineers have built an advanced heat pump and connected it to an energy storage system using two silos full of plain old gravel that they say is as cheap as pumped hydro, as location-agnostic as a battery - and is super efficient. Using the heat pump as the key, the team built an energy storage system that compresses argon gas to produce a temperature differential and deposits heat and cold into two separate large silos of gravel. Energy is stored in the gravel and when the process is reversed, it can be released.
PG&E Brightsource deal breaks solar contract record
The contracts secure 1,310 megawatts of solar thermal power from seven projects, the first of which - a 110MW installation in Ivanpah, California - is slated to be online by 2012. Construction is set to begin in "about six months, following approval from the California Energy Commission and the Bureau of Land Management," says BrightSource chief executive John Woolard in an interview published on PG&E's Web site.
GE to Invest $100M+ in New York Battery Plant
General Electric has announced that it plans to build a new battery factory in upstate New York with an "initial investment" of $100 million and additional funds requested under the stimulus package. First up for the New York plant, if all of the financing comes through: batteries for hybrid freight trains. It's looking at providing energy storage devices for other applications including utilities, telecoms and load leveling for the smart grid. At full capacity, the new plant is designed to produce 10 million battery cells, or about 900 MW-hours of energy storage per year.
Clayton i-House - $93,300
"This innovative 'green' home , featuring solar panels and numerous other energy-saving products, is truly a home of the future," Warren Buffett wrote his shareholders. "Estimated costs for electricity and heating total only about $1 per day when the home is sited in an area like Omaha." The "i-house's" metal v-shaped roof - inspired by a gas-station awning - combines design with function. The roof provides a rain water catchment system for recycling, supports flush-mounted solar panels and vaults interior ceilings at each end to 10 1/2 feet for an added feeling of openness. The Energy Star-rated design features heavy insulation, six-inch thick exterior walls, cement board and corrugated metal siding, energy efficient appliances, a tankless water heater, dual-flush toilets and lots of "low-e" glazed windows.
IEEE launches smart grid interoperability standards project
Leveraging the technical breadth of the IEEE and its open standards development process, IEEE P2030 will provide a knowledge base for understanding and defining smart grid interoperability of the electric power system with end use applications and loads. It will involve the integration of energy technology and information and communications technologies, which is necessary to achieve seamless operation for electric generation, delivery, and end-use benefits that will permit two-way power flow with communication and control.
