Cogeneration of electricity and heat is one of the most promising means of using existing technologies for sustainable ends, but it is also one of the most neglected and least understood. Cogeneration can dramatically increase energy efficiency, slash carbon emissions, and save money.

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.

- 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.

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.

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.

Using the sun combined with nature's way of turning solar power into life-sustaining energy can be captured, artificially induced and could provide enough power in less than an hour to run the house, the car and bring on an era of true energy independence. The power of solar is not on the grand scale of collectors spread over square acres in the west desert, says Daniel Nocera, a widely cited chemist at the Massachusetts Institute of Technology who is scheduled to speak at Utah State University this week.

The presidential candidates are stumping hard. And while energy and environmental issues are getting frequent mentions, both the Republican and Democratic leaders are neglecting one area: geothermal energy. It now makes up just a sliver of the electricity generation pie. But experts at the Massachusetts Institute of Technology say that the technology could have far wider applications and be especially useful in times of high energy prices and carbon constraints. Not only is it much cleaner than fossil fuels but it also provides a continuous flow of energy -- all at a competitive prices.

(NaturalNews) Scientists have increasingly warned that a hasty switch from fossil fuels to biofuels may actually accelerate global warming rather than helping to avert it, leading U.K. Prime Minister Gordon Brown to declare his opposition to new European Union biofuel standards that will soon be going into effect.

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.

New greenhouse gases emitted in making flat-screen televisions or some refrigerants might be capped under a planned U.N. treaty to combat global warming, delegates at U.N. talks in Ghana said on Friday. Emissions of the recently developed industrial gases, including nitrogen trifluoride and fluorinated ethers, are estimated at just 0.3 percent of emissions of conventional greenhouse gases by rich nations. But the emissions are surging.

ntel on Thursday showed off a wireless electric power system that analysts say could revolutionize modern life by freeing devices from transformers and wall outlets. Intel chief technology officer Justin Rattner demonstrated a Wireless Energy Resonant Link as he spoke at the California firm's annual developers forum in San Francisco.

You can't always get what you want, the Rolling Stones counseled. But if you try sometimes, you get what you need. Factor billions of dollars, questionable loyalties and a privatization rap sheet invested more in profit than people into the equation, and you usually can get both what you want and what you need. In the case of hyper-loaded oil tycoon T. Boone Pickens, that means having your cake on climate crisis, fossil fuel addiction, eminent domain, water privatization and corporate earnings -- and eating it too.

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.

Australia is the dryest nation on earth, always was always will be, the trouble is Global warming is making the situation worse and rainfall is reducing in a disturbing pattern. For two centuries since European settlement the States have fought over 'Water-Right's' and the use of water to the detriment of the environment and ultimately to the sustainability of everyone residing here. The Murray-Darling Basin is 3,370km long, drains one-seventh of the Australian land mass, and is currently by far the most significant agricultural area in Australia. The name of the basin is derived from its two major rivers, the Murray River and the Darling River.

Vermont's four largest electric utilities believe the state needs new generating plants to replace at least some of the power they buy from outside sources. As VPR's Ross Sneyd reports, the companies say the plants should be powered by renewable energy, such as wood or wind.

The Federal Government will provide $50 million to the geothermal industry to help it begin making the technology viable for baseload energy production. Speaking to Alexandra Kirk on ABC Radio's AM program, the Minister for Resources and Energy, Martin Ferguson, said there was huge potential for geothermal energy in Australia.

Ikea's innovation was to cut storage and transport costs with flat-pack furniture, and at the same time bring some simple and attractive design to mass manufacturing. Now the Swedish company plans to bring this buying power to alternative energy. Johan Stenebo of Ikea spinoff company Greentech will invest $75 million in solar companies and wants the retail giant to start selling the products in Ikea store in two to four years.

Our American way of life is unsustainable; rather than attempting to perpetuate it, we must transition beyond it-quickly. Should we fail to do so, our society will collapse-in the not-too-distant future… Message to mainstream America: our American way of life-300+ million people enjoying historically unprecedented living standards-has been enabled by our increasingly dysfunctional ecological and economic behavior over the past 200 years. Our existing way of life is therefore unsustainable; in fact, America is facing imminent societal collapse.

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.
