By changing the way that conventional silicon solar panels are made, Day4 Energy, a startup based in Burnaby, British Columbia, has found a way to cut the cost of solar power by 25 percent, says George Rubin, the company's president.

While still a small percentage of overall electric generation, there's no denying that wind power has been growing consistently in the United States. In 2007, an additional 5,329 megawatts of capacity was added, an amount which was slightly more than a quarter of all new global wind capacity that year. Currently an additional 8 gigawatts of wind capacity is under construction and scheduled to be operational by the end of 2008. The result: This will be the third straight year that the United States leads the world in annual wind power installations, according to a new study by Emerging Energy Research.

It is time to pay close attention to President Eisenhower's warning. In the past six months, the U.S. Air Force (USAF) has begun a major effort to define the future of energy supplies for the U.S. and for its military allies. If military brass reach their goal, the transportation fuel of the future will be based on coal. According to Air Force Assistant Secretary William Anderson, the USAF plan is to:

The world is finally doing something about climate change. People are changing their light bulbs and buying hybrid vehicles. Renewable energy is gaining ground. But is this enough? Policy-makers insist that environmental responsibility not come at the expense of economic growth. Massive populations in China and India are playing catch-up with America's consuming and polluting ways. And on a planet biologists believe can only support a few billion humans over the long haul, our population is near seven billion and continuing to rise. Will our efforts to save the planet be nullified by our worship of growth?

State regulators in Colorado have given the green light to plans by Xcel Energy to shut down two coal-powered energy plants in the state, and build one of the world's largest utility-scale solar-power facilities. Following discussions lasting several days, the Colorado Public Utilities Commission (CPUC) backed the power company's voluntary decision to close the two coal-fired plants at Denver and Grand Junction, making Xcel the first utility in the U.S. to make such a move solely in an effort to reduce emissions.

It is a sad commentary on the culture we live in that so many of us are afraid to exercise our right to use the public roads in a non-polluting manner. Believe me, I know how you feel. I went from not riding my bicycle for many, many years and have since become a 4-season rider in the northern midwest. Here are some things that have helped me make the transition.

This map is from the August 2008 "Humanitarian Implications of Climate Change" report, commissioned by U.N. OCHA and CARE. It shows cumulative humanitarian risk hotspots for all three climate-related hazards studied - floods, cyclones and drought. Areas at risk of more than one type of hazard are considered to be of most concern for humanitarian actors.

Giving away bicycles to commuters to get them out of their cars is no longer strictly a private enterprise. The state and King County are trying it as well. A new "green bike" program announced Thursday is aimed at getting 300 workers to reduce their commute trips by 60 percent between now and May.

New South Wales, Australia is the site of a pilot project where solar thermal technology reduces the use of fossil fuels. Coal and solar generate electricity using the same turbines. Coal power plants can utilize solar to produce 15%-60% of the electricity. A higher quantity is possible, but requires significantly more modifications to be made to the coal boilers.

- Amid mounting agreement that future clean, "carbon-neutral", energy will rely on efficient conversion of the sun's light energy into fuels and electric power, attention is focusing on one of the most ancient groups of organism, the cyanobacteria.

The cost of oil peaked above $140 a barrel this summer, nearly double the price a year earlier and 40% higher than worst-case scenarios discussed just months earlier. Gas prices followed suit, peaking well above $4 a gallon during peak driving season and sending drivers, carmakers and politicians all into fits. Heating oil prices started climbing to record levels months before heating season.

Exxon Mobil agreed to pay out 75 percent of a $507.5 million (276 million pounds) damages ruling to settle the 1989 Exxon Valdez oil spill off Alaska, the Anchorage Daily News reported on Tuesday. Citing both Exxon and the plaintiff's lawyer, the Anchorage Daily News said the oil giant will release about $383 million for distribution to the nearly 33,000 commercial fishermen and others who sued Exxon after the worst tanker crash in U.S. history.

At the risk of sounding like a cheerleader, the scale of some of the new solar power plants being announced over the past few weeks are just astounding. PG&E has contracted with a 250 MW and a 500 MW solar plant in California, a 250 MW integrated solar plant/manufacturing facility is being built in India, and the Clinton Foundation is discussing building a similar 5,000 MW facility in a different part of India. At the beginning of the summer a new 10 MW thin-film facility was claiming the record for that category and a 400 MW solar thermal plant in the Mojave Desert was big news. Furthering the great solar scale-up:

Their mission: to deliver cost-efficient solar electricity. The Nanosolar company was founded in 2002 and is working to build the world's largest solar cell factory in California and the world's largest panel-assembly factory in Germany. They have successfully created a solar coating that is the most cost-efficient solar energy source ever. Their PowerSheet cells contrast the current solar technology systems by reducing the cost of production from $3 a watt to a mere 30 cents per watt.

Feed-in Tariffs in 70 words or less: Government and power utility offers premium, long-term contracts to residential, commercial, and industrial citizens to generate power on-site. Rates are based on the cost of buying and installing various renewable energy systems, but only paid on actual power produced. Citizens purchase back grid power, as per usual, from utility at regular prices. Increase in cost is paid for with a small surcharge to all electricity ratepayers.

The Peruvian alternative energy company Iberoperuana Inversiones SAC has commenced construction on a 240 megawatt wind energy farm. It is Peru's first major alternative energy project. Iberoperuana Inversiones plans to invest $240 million in the farm, which is projected to provide clean electricity for an estimated 80,000 families in Peru's southern desert region of Paracas. The wind energy park will be located near the city of Ica (near Paracas National Park and the Nazca Lines) and will be known as the "Parque Eólico San Andrés" (San Andrés Wind Park).

Geothermal power is getting a closer look from several directions. These new studies are based on "hot rocks" at temperatures of around 150 degrees C (about 300 degrees F) that can be reached by drilling a couple of miles into the earth's crust. This is a much more involved approach than dealing with surface or near-surface geothermal activity, as is used for much of Iceland's power generation.

tullamarine interchange, tullamarine solar power, solar power, solar sound barrier, solar power barrier, sound-proof solar panels, noise reduction solar barriers In the search for a solar solution to power our cities, one of our biggest obstacles is the massive acreage required by conventional arrays. Photovoltaic panels are flat and expansive, and urban centers are at a serious loss for free space. Now Australian renewable energy retailer Going Solar has conceived of a clever strategy that infuses urban transit systems with energy producing potential - install solar panels in highways as sound barriers!

A New Jersey company said on Tuesday it will invest $20 million over three years to develop an underground compressed-air storage system for wind turbines and other power sources, a sign of growing confidence in the technology. Energy Storage and Power is a joint ventured formed by energy developer PSEG Global and Michael Nakhamkin, who designed the only compressed air-storage facility in the U.S.

We could be generating huge amounts of power from sewage. The process is pretty simple - just ferment sewage to produce a fuel called biogas. Biogas is almost entirely methane, and so is natural gas, so the two are essential interchangeable. The potential to produce biogas is almost entirely overlooked by most countries - except Sweden.
