Morningstar Corporation is pleased to announce the introduction of a solar string calculator on its website.
The stimulus package announced by Australia's Prime Minister Kevin Rudd has missed opportunities to simultaneously improve Australia's sustainability in energy use and reduce greenhouse gas emissions, according to Western Australia's largest peak body for the sustainable energy sector.
Western Australia's largest peak body for enterprises across the sustainable energy sector has welcomed an agreement between from Synergy and Carnegie Corporation that will create new renewable energy projects in Western Australia.
If the U.S. is going to generate 20 percent of its electricity from the wind in the next 20 years, wind turbines will need to evolve in every way - larger, taller, less expensive, more reliable and more efficient. At NREL's National Wind Technology Center , engineers are preparing to install the two largest turbines ever tested at the laboratory. Key elements of a 1.5 MW General Electric turbine have begun arriving; instrumentation and equipment testing should begin by late summer. Installation of a 2.3 MW turbine from Siemens Power Generation is scheduled for late summer, too. Full story here.
Leading energy efficiency group Easy Being Green has strongly backed the Rudd Government's package to make homes more energy efficient by increasing the solar hot water rebate and providing insulation for 2.7 million Australian households.
Evergreen Solar, Inc. (Nasdaq: ESLR), a manufacturer of STRING RIBBON' solar power products with its proprietary, low-cost silicon wafer manufacturing technology, announced today it has appointed Chinua Ejeka as Applications and Field Support Engineer for Europe.
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.
