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.

Geothermal Energy We have found the company that is ready to lead the way on this exciting new energy technology. The company is one of the world's leading vertically integrated companies in the field of geothermal energy. Geothermal energy is one of the cleanest, most abundant sources of energy on the planet and now is the time to know as much as possible about this great new investment. This companies technologies and its subsidiaries engage in the geothermal and recovered energy power business. Before we get into the details of this business, lets take a closer look at what geothermal energy really is.

The value consumers place on goods and services often is a matter of simple economics. When demand is high and supply low, relative worth heads north. This fundamental truth from our friend Adam Smith couldn't be more relevant to the car business these days. Visit any dealership and ask how many thousands of dollars in incentives are available on trucks and SUVs collecting dust on the lot. On the flip side, the Prius hybrid's massive worldwide appeal is not only a sign of our energy-afflicted times but proof of what happens when there are more shoppers than cars.

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.

TreeHugger has a post on micro-wind power devices for the home - Hot Home Wind Turbines You Can Actually Buy, Plus One You Wish You Could. Though solar panels definitely hog the renewable energy stage when it comes to home installations, a number of new, innovative wind turbines have entered the market in the past couple of months. Not all of these are intended to be mounted on your roof, some you'll need a bit of a yard (and a dearth of neighbors) to install and they vary in price from affordable to "when am I going to actually pay this off?", but they all go to show that there's more than one way to harness the wind to generate electricity. Check 'em out...

Japan has announced plans to build its first new geothermal power stations in nearly two decades in a bid to tap the nation's domestic energy sources. A string of geothermal power plants are to be developed by a number of firms keen to capitalise on the active volcanic landscape that spans the country, while the government is also currently compiling guidelines supporting the development of such energy sources. Home to 108 active volcanoes - ten per cent of the world's active volcanoes - Japan is in a prime position to tap into underground geothermal energy sources. As a nation with few natural resources, Japan has long been dependent on importing substantial quantities of crude oil and natural gas. The country's renewed focus on geothermal energy marks a desired shift away from its dependency on imported energy sources which has made it susceptible to increasingly volatile prices.

Not sure whether a wind turbine on your property would generate enough energy to be worth the effort? Stew no more: the Carbon Trust has launched a new "Wind Yield Estimation Tool" on its Website. The tool lets users calculate their annual mean wind speed, potential energy generation and carbon savings based on postcode, landscape and type of wind turbine. According to the Carbon Trust, the tool is the "most rigorous of its kind" and is based on 30 years of data from the Met Office's 220 weather stations.

Renewable Energy World has an article on the state of play in the ocean energy market - Harnessing the Tides: Marine Power Update 2009 One hundred and forty-one years ago, the relentless sea off Scotland's coast inspired the following observation from native son and author George MacDonald. "I climbed the heights above the village, and looked abroad over the Atlantic. What a waste of aimless tossing to and fro! Gray mist above, full of falling rain; gray, wrathful waters underneath, foaming and bursting as billow broke upon billow…they burst on the rocks at the end of it, and rushed in shattered spouts and clouds of spray far into the air over their heads. "Will the time ever come," I thought, when man shall be able to store up even this force for his own ends? Who can tell?"

REW has an article on making the switch to a clean energy world - Will the Children of Today Be Living in a World Powered by Renewable Energy by 2050?. The world needs a one-off switch-over to renewable energy -- and this could be largely accomplished in just forty years time, slashing energy costs and greenhouse gases while allowing healthy economic growth, experts say. By 2050, 80 percent of the world's electricity could be coming from renewable energy sources provided efforts are made, in parallel, to improve energy efficiency, according to a study by the German Aerospace Center (DLR). That means, the children of today might well grow up to experience a world where the energy they use comes almost entirely from the sun, wind, sea and biomass. By 2090, the shift to renewable energy around the world could be almost 99 percent completed reducing pressure on the environment and laying the foundations for a new era of prosperity based on green energy.

Solar Power Authority has a post on the solar powered Google headquarters - Googleplex Solar. The Googleplex headquarters located in Mountain View California has installed one of the largest corporate solar power structures of any other company to date. The array consists of 9,212 solar panels produced by Sharp Electronics and has a capacity of 1.6 Megawatts (MW) which cover's ~30% of the Google campus electricity needs, the equivalent of roughly 1,000 California homes. This installation is said to save Google $393,000 in electricity per year and can be monitored real time at this interactive page that contains data on the electricity being produced. One of the most unique features of the Googleplex array of solar panels is that it contains several clusters of solar trees. These parking lot covers are designed to keep cars cool while also producing electricity and serving it to both the Googleplex or plugin hybrid electric cars (PHEV's).

Inhabitat has a post on Toyota's latest hybrid vehicle design - Toyota's New Hybrid MR2 Revealed!. The Toyota MR2 sportscar is hitting the road, remade from its older version into a Prius-inspired hybrid vehicle. The new MR2 will draw inspiration (and technology) from the iconic Toyota Prius, with the goal of creating a mass market hybrid sportscar that is as fun to drive as it is green. Toyota's development of the MR2 is not to one-up the Tesla Roadster, but rather to create a car that can do a reasonable 0-60mph in seven seconds and get an incredible 60mpg. We are all familiar with Toyota's efforts to create a mass market electric vehicle. The Prius, after all, is the best known green car on the market. So looking to capitalize on such technology while creating a sportier, much more dynamic looking vehicle has great implications for both a consumer market and the corporation's innovation.

The Guardian has an article on a report from Greenpeace, the European Solar Thermal Electricity Association and the International Energy Agency's SolarPACES group on the potential for solar thermal power to supply a large proportion of our energy needs (why they limit it to 25% is a mystery to me) - Concentrated solar power could generate 'quarter of world's energy'. Solar power stations that concentrate sunlight could generate up to one-quarter of the world's electricity needs by 2050, according to a study by environmental and solar industry groups. The technology, best suited to the desert regions of the world, could also create hundreds of thousands of new jobs and save millions of tonnes of CO2 from entering the atmosphere. Concentrating solar power (CSP) uses mirrors to focus sunlight onto water. This produces steam that can then turn turbines and generate electricity. It differs from photovoltaics, which use solar panels to turn sunlight directly into electricity and can operate even on overcast days. CSP only works in places where there are many days with clear skies and is a proven, reliable technology. At the end of 2008 CSP capacity was around 430MW, and worldwide investment in the technology will reach

Not everyone wants to have a home computer. They may work on one every day and think it would be an outrage to have to have one at their house as well. On the other hand, you might have a computer at home that basically works well but is not great for storing files, or running out of memory quickly.
