EnerWorks has made a bold statement of its commitment to solar cooling with its technology now powering the largest solar thermal heating and cooling installation in the world.
The Geothermal Resources Council s extending an invitation to students to submit abstracts for presentation at its 2009 Annual Meeting in Reno, Nevada, October 4-7, 2009.
Limited gas pipeline connectivity and rising natural consumption rate in the domestic market will force Spain to import more LNG in the coming years.
New measures to stimulate the economy can also address energy security and greenhouse gas emissions, according to Western Australia's largest peak body for enterprises across the sustainable energy sector.
The eco-sheet shows that there is no silver bullet solution. When looking at CO2 emissions only, it would be clear what options to take. However, this is not the only environmental consideration. Not preferring any particular method of electricity generation, the eco-sheet lists the main environmental impact categories and benchmarks them against the electricity generation mixes for the EU 25 and EU 15.
Lead-carbon batteries are different from other types of batteries because they combine the high energy density of a battery and the high specific power of a supercapacitor in a single low-cost device. The primary goals of lead-carbon research have been to extend the cycle lives of lead-acid batteries and increase their power.
The grid will need to be totally redesigned to integrate small generation inputs from PV, wind, biomass and other more sustainable system inputs, the majority of which will need to utilize energy storage to provide reliable energy reduction.
What do supermarkets do with their products when the expiry date has been reached? Surprisingly, there are only a limited amount of options. Belgian retailer Colruyt has found a sustainable angle: they convert it to green power.
Jet travel has both been a time saver and a giant waste of energy. More fuel has been consumed in jet travel than by all the cars in the US combined. About 19.4 billion gallons of fuel are consumed by air travel within the US. Since these planes cannot use an alternative fuel, conservation is the only answer.
Somewhere in the mid 1980's, the NAHB Research Center in Washington was run by a guy I knew (whose name I can't seem to dig up) who had a wacky vision. His idea was to reinvent the way electrical power was distributed throughout the home. They called it Smart Home (not to be confused with the Disney movie of the same name or other stuff that uses that name now). I think it was the first use of the name.
Pyrolysis is the thermal decomposition of biomass occurring in the absence of oxygen. It is the fundamental chemical reaction that is the precursor of both the combustion and gasification processes and occurs naturally in the first two seconds. The products of biomass pyrolysis include biochar, bio-oil and gases including methane, hydrogen, carbon monoxide, and carbon dioxide. Depending on the thermal environment and the final temperature, pyrolysis will yield mainly biochar at low temperatures, less than 450 0C, when the heating rate is quite slow, and mainly gases at high temperatures, greater than 800 0C, with rapid heating rates. At an intermediate temperature and under relatively high heating rates, the main product is bio-oil.
The sun's heat passes through the windows and gets absorbed by dense materials like brick, stone, concrete, or rammed earth that will store the heat and release it later. Also called "Thermal Mass", these heavy materials serve to keep the house from overheating when the sun shines and later release heat when the sun is not shining.
Our plan recognizes that fuel cells are being developed for a variety of applications and have matured at different rates. Certain applications are ready for early market support, while others still would benefit from additional research and development funding.
The global financial crisis dominated the news media in the second half of 2008. The crisis is certainly negatively affecting the sustainable energy market in the short term. On the other hand, the crisis has generated broad public demand for government investments that create employment and stimulate the economy.
In 2007, and during the first half of 2008, all the signs for PV were positive. There was a very attractive feed-in tariff in Spain, credit lines were easy to get, oil prices were rising and economies growing rapidly. Now, the industry faces a strong head wind with oil prices very low, economies in recession, finance hard to obtain and the world's largest market regulated by a cap with a 30% lower feed-in tariff.
