Construction on the nation's first solar demonstration project in a highway right of way has begun. At the Interstate 5 and Interstate 205 interchange in Tualatin, Oregon, 594 solar panels are being installed on a strip of land beside the highway roughly the length of two football fields. Governor Ted Kulongoski, with transportation and utilities officials, broke ground on Thursday on the all-Oregon project.

Sunrgi, a Hollywood-based start-up, came out of stealth mode this week claiming it can collect twice as much sunlight as other photovoltaic designs and convert it to electricity for 5 cents a kilowatt-hour, on par with fossil fuels.

News flash: Terrorists sink an oil tanker, blocking the vital Bosporus Strait. Oil rockets to $160 a barrel and gasoline to $5 a gallon in the United States. What can keep the globe's biggest oil-guzzling economy from running dry?

Reduce 6. Reinvest 2. Share 7. Relocalize 3. Diversify 8. Reengineer 4. Distribute 9. Reskill 5. Store 10. Remobilize

Traffic was piling up going from West Seattle to Interstate 5 - and that meant Rich Feldman had to drive a few feet and stop, over and over, all the way up the access ramp. As they looked out at the line of cars ahead of their plug-in Toyota Prius, Feldman and the business executive sitting beside him, John Clark, couldn't have been happier.

Here at Inhabitat we love to see innovative reuses for organic waste, and so we're perpetually fascinated by the potential of poo to be used as a renewable source of energy. Last week Dutch agriculture minister Gerda Verburg announced a groundbreaking development for the field as she unveiled the world's largest biomass power plant to run exclusively on poultry manure. The plant will convert a third of the nation's chicken waste into energy while running at a capacity of 36.5 megawatts - enough to power 90,000 homes!

Kramer Junction. Nevada Solar One. Andasol 1. Kimberlina. They're obscure names today. But they'll be household names tomorrow. The reason? Each is now providing 'here and now' proof concentrating solar power (CSP) works. That can't be said for cabon capture and storage. Nor can it be said for 'next generation' nuclear. Each faces years of additional research and development before some 'first mover' will be game enough to build one. That just isn't the case with concentrating solar power. It's got 20 years of proven commercial operation (Kramer Junction) behind it. It also has new innovations coming on line (Nevada Solar One), with solar thermal storage (Andasol 1), and the promise of super-low costs in coming years (Ausra's Kimberlina). What it adds up to is a price-declining research and development juggernaut in concentrating solar power. This is rapidly bringing concentrating solar power closer to competitiveness with dirty fossil fuels. The California Energy Commission estimates this price 'cross over' could happen by 2015. Bulls predict sooner. And in an industry where new plants and equipment can last 40 years, 5-7 years from now is like tomorrow. What this means is that for forward planning of new infrastructure, concentrating solar power is already nipping at the heels of coal. Toss in carbon prices and the reduced likelihood of protesters chaining themselves to bulldozers as they are likely to at any new coal plants, CSP starts looking like a VERY good deal indeed.

The US Department of Energy (DOE) issued a Funding Opportunity Announcement (FOA) for up to $6 million over two years (FY09-FY10), subject to annual appropriations, to address wind development technical challenges and market acceptance barriers as outlined in the "20% Wind Energy by 2030" report published in July 2008. The announcement will address six topic areas: (1) turbine research, development and testing; (2) distributed wind technologies; (3) market acceptance efforts; (4) environmental research and sitting strategies; (5) transmission analysis, planning and assessments; and (6) workforce development.

Matthew Simmons has received quite a bit of press in the past week, after his Ocean Energy Institute floated a proposal to build a $25 billion, 5 GW wind farm in the Gulf of Maine. Offshore wind farms have a number of advantages over their land based equivalents - they are less hazardous to wildlife, have fewer objections raised on NIMBY concerns and winds are generally stronger over the oceans than they are over land.

Spain has set a record this week by powering 29-40% of its electricity needs from wind energy. A huge 11,180 MW was generated on Thursday when high winds blew through north west Spain. When demand was lower early in the morning, wind energy supplied 40% of the country's requirements whilst later on when demand rose, wind energy supplied 29%. This year wind turbines have supplied 11.5% of electricity demand in Spain positioning the country as the third biggest producer of wind energy next to Germany (second) and the US (first). There is a national target of reaching 20,000 MW by 2010. This compares with a figure of just 7300 MW likely to be operational in the UK by 2010 (the number currently built or with planning consent). Companies with a significant presence in Spain are Iberdrola, Acciona and Endesa.

March 3, 2009 Arizona based First Solar has achieved a major milestone in reducing the manufacturing cost for solar panels below the $1 per watt price barrier - the target necessary for solar to compete with coal-burning electricity on the grid or grid-parity. Using cadmium telluride (CdTe) technology in its thin-film photovoltaic cells, First Solar claims to have the lowest manufacturing cost per watt in the industry with the ability to make solar cells at 98 cents per watt, one third of the price of comparable standard silicon panels. The efficiency is in part due to a low cycle time - 2.5 hours from sheet of glass to solar module - about a tenth of the time it takes for silicon equivalents.

For all of solar power's positive attributes and benefits, the most obvious drawback it suffers from is its marriage to the sun; the sun must shine for the power system to work.

Presently, the world consumes in the neighborhood of approximately 18.5 TW [terawatts; 18,500 gigawatts (GWe)/18,500,000 megawatts(MWe)] with virtually no all-electric vehicles on the highways.

So far, CNG vehicles haven't made a blip on my radar screen, even though the group Natural Gas Vehicles for America (NGVA) estimates there are 150,000 NGVs on U.S. roads today and over 5 million worldwide. It took a phone call from sunny Southern Utah to clue me in to recent developments, which include a local refueling station overflowing with CNG-hungry vehicles. There are about 1500 CNG refueling stations in the US, which is about the same number of commercial stations offering E85 ethanol blends. Utah has a total of 91 CNG filling stations, most of which are reserved for commercial fleet use, but there are 20 open to the public. According to an article by the Associated Press, you could drive Utah from top to bottom and hit 22 different stations offering compressed natural gas.
