A Canadian company says that it has developed a way for makers of precast concrete products to take all the carbon-dioxide emissions from their factories, as well as neighboring industrial facilities, and store them in the products that they produce by exposing those products to carbon-dioxide-rich flue gases during the curing process. Industry experts say that the technology is unproven but holds great potential if it works.

Dubbed the "missing greenhouse gas," nitrogen trifluoride (NF3) was found by a recent study to have a global climate impact 17,000 times greater than carbon dioxide. The chemical is found in the LCD panels of cell phones, televisions, and computer monitors, as well as in semiconductors and synthetic diamonds. The chemical is not one of the greenhouse gases monitored by the Kyoto Protocol, due to the fact that LCDs were not produced in significant quantities when it was drafted.

The jury is still out on whether hydrogen will ultimately be our environmental savior, replacing the fossil fuels responsible for global warming and various nagging forms of pollution. Two main hurdles stand in the way of mass production and widespread consumer adoption of hydrogen "fuel cell" vehicles: the still high cost of producing fuel cells, and the lack of a hydrogen refueling network.

With gas prices going through the roof and regulators requiring cars to be ever more miserly, Volkswagen is bringing new meaning to the term "fuel efficiency" with a bullet-shaped microcar that gets a stunning 282 235 mpg. Volkswagen's had its super-thrifty One-Liter Car concept vehicle -- so named because that's how much fuel it needs to go 100 kilometers -- stashed away for six years. The body's made of carbon fiber to minimize weight (the entire car weighs just 660 pounds) and company execs didn't expect the material to become cheap enough to produce the car until 2012.

The world's oceans are an energetic place, and military-industrial giant Lockheed Martin said today it has been granted $1.2 million by the Department of Energy to demonstrate that ocean thermal energy conversion is possible. Although the ocean often doesn't feel very warm, the temperature gradient between the warm, sun-soaked surface and the frigid, dark depths provides enough of a differential to run a heat engine. The idea has been kicking around for over a century but has never been scaled. Lockheed Martin helped build the largest ocean thermal energy conversion system to date back in the 80s, but it only ever produced 50,000 watts, or .05 megawatts.

Congress' financial bailout included an increase and extension on tax credits for solar energy users, still mostly an option for the rich. Earlier this year, Vicki Eckels put a state-of-the-art solar power system on her house in Fort Lauderdale for $43,000. ''I feel good because I'm a clean energy producer.'' The federal government will reward her by knocking off $2,000 from her 2008 taxes. If she had waited until next year to install the system, her tax savings could have been $12,900, thanks to a provision hidden within the massive bailout Congress passed last week.

Alternative energy giant Horizon Wind Energy wants to trap the immense potential of wind energy. They are planning to open an Indianapolis office for developing up to four new wind farms in Indiana. It will cost them more than $2 billion. Indiana wind farms will be the largest of the Horizon's farms and the proposed site will be at Meadow Lake in White County. The company will install up to 660 turbines spread over 100,000 acres. When the project is fully operational it could produce more than 1,000 megawatts per year - enough to power 300,000 houses.

Chemists claim that by mimicking photosynthesis in the lab, they could revolutionize fuel production within five years. Katharine Sanderson reports. Dan Nocera, a chemist at the Massachusetts Institute of Technology (MIT), Cambridge, made a bold statement at the American Chemical Society's fall meeting in Philadelphia last month. He claimed that within five years he could build a device capable of producing locally sourced hydrogen gas, which could power all the world's houses, fill people's car batteries and revolutionize energy supply in the developing world. "I guarantee, in under five years, you'll see this," he said.

A cheap new way to attach mirrors to silicon yields very efficient solar cells that don't cost much to manufacture. The technique could lead to solar panels that produce electricity for the average price of electricity in the United States.

The solar power installation at Applied Materials' headquarters is further evidence that companies looking to go green should think blacktop. The Sunnyvale, Calif.-based maker of gear for making high-tech products announced Friday that it has completed the installation a pair of solar power systems that together can produce 2.1 megawatts of energy--which qualifies it, the company says, as the "largest solar power deployment at a corporate facility in the United States."

A new breed of solar tower may soon be sprouting up in Namibia, providing the nation with a carbon-free source of electricity and food during the day and night. At one and a half kilometers tall and 280 meters wide, these massive solar updraft towers could potentially produce 400MW of energy each - enough to power Windhoek, the nation's capital. Proposed by intellectual property company Hahn & Hahn, the towers generate energy by forcing heated air through a shaft lined with wind turbines. Additionally, the base of each tower will function as a 37 square km greenhouse where crops can be grown.

A group of Spanish developers working for a company called Ecofasa just announced a new biofuel made up from trash. This isn't a biodiesel made from used frying oil; instead, it's made from general urban waste which is treated by bacteria. The result of that bacteria? Fatty acids that can be used to produce standard biodiesel. According to the company's CEO, the process is fully biologic, competes with no feedstock and is really sustainable. However, the process doesn't yield that much actual fuel: just one liter of biodiesel from 10 kg of trash. The project is now in a development phase, but Ecofasa said that a commercially viable model could be ready in three to four years.

In a significant milestone in the deployment of flexible, printed photovoltaics, Konarka, a solar-cell startup based in Lowell, MA, has opened a commercial-scale factory, with the capacity to produce enough organic solar cells every year to generate one gigawatt of electricity, the equivalent of a large nuclear reactor. Organic solar cells could cut the cost of solar power by making use of inexpensive organic polymers rather than the expensive crystalline silicon used in most solar cells. What's more, the polymers can be processed using low-cost equipment such as ink-jet printers or coating equipment employed to make photographic film, which reduces both capital and manufacturing costs compared with conventional solar-cell manufacturing.

Energy Matters has a post on a new solar PV farm in Portugal - Portugal's Largest Solar Farm Opens. Portugal's Acciona Energy recently opened the country's largest solar power farm, executing the construction of the project in a record time of 13 months. The solar farm covers an area of 250 hectares in the municipality of Moura (Alentejo region), near the border with Spain. The AUD$571 million 48 MW facility will provide power to over 30,000 Portugese households; producing 93 million kWh of electricity annually and avoiding over 89,000 tonnes of carbon dioxide emissions compared to a similar output via coal fired power generation.

The nature has paid the price for extraordinary expansion of human civilization; the non-renewable energy resources of the world have been nearly exhausted. Now scientists all over the world are trying to work out a solution to make up the energy shortage that the human civilization is going to face in the coming years. Among many other products under development, the scientists have invested great hopes in the potentials of wind powered electricity generators. This is a system that harnesses the power of the wind to produce usable energy.

Having almost been run off the road by Iowa's gusty winds, I'm not surprised to hear about the state's interest in wind energy. But the scale of its current project- a one billion dollar wind farm- is truly impressive. The proposed Trade Wind Energy farm will feature 335 wind generators that can produce up to 500 MW of energy. Each generator will be able to power 500 to 1,000 homes. The generators will each be at least 1,000 feet apart, and property owners in the vicinity will receive rent for use of wind rights. Project details haven't been finalized, however, and the number of wind generators will ultimately depend on success in leasing property rights. But Trade Wind Energy representatives are confident that the project will go ahead as planned since some leases have already been signed and area farmers seem receptive.

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.

Coal plants are abundant in the United States. According to the Department of Energy they produce around 49% of the energy that we use.

Imagine cars with no tailpipes and no direct carbon emissions into our atmosphere - powered by an electrical energy system getting cleaner by the year through Renewable Portfolio Standards in effect in California and across the nation. More than a decade ago, I was one of the original owners of the EV1, an electric vehicle produced by General Motors (GM). When GM discontinued the series and reclaimed all of the EV1s, it was a major setback for the American car industry. Instead of leading the charge to create a new generation of vehicles - America fell behind.
