Q&A: Bill Gates on the World's Energy Crisis | Magazine - 5 views

  • You could have the government throw money at the most politically favored guy in the country to go build a battery factory. And there are billions of dollars that have been assigned to that waste. Or you could actually back people who have better battery ideas.
  • We’re putting 90 percent of the subsidies in deployment—this is true in Europe and the United States—not in R&D. And so unfortunately you get technologies that, no matter how much of them you buy, there’s no path to being economical. You need fundamental breakthroughs, which come more out of basic research.

Germany on the Verge of a Subsidy for Energy Storage - 1 views

  • The energy storage system is meant to be used in tandem with distributed solar installations with storage systems developed in Germany; the funds come with a maximum size requirement of 30 kilowatts. The batteries must have a warranty of at least seven years to gain the subsidy. Another requirement is that the PV installation sends 60 percent of its capacity to the grid over the lifetime of the plant. The battery subsidies will apply retroactively when connected to solar systems installed in 2013, according to reports in PV Magazine.

Feed-in Tariffs in Ukraine ranking among the highest in Europe - Environmental technolo... - 0 views

  • Ukraine seeks to reduce its current dependency on gas imports. To address the issue, a number of initiatives are being taken which are aimed at boosting energy efficiency, introducing energy saving technologies and renewable energy resources. The feed-in tariffs effective since April 2009, rank among the highest in Europe, which considering the saturated European market, makes Ukraine especially luring for the foreign investors in the field. As forecasted by the government, in the next 3-4 years Ukraine will be able to attract about 3 billion dollars of private investments for the development of renewable energy production.

    I've been mindful of the amount of water I use when making a pot of coffee ever since learning that one-third of the tap water used for drinking in North America is actually used to brew our daily cups of joe-and that if each of us avoided wasting just one cupful of coffee a day, we could save enough water over the course of a year to provide two gallons to every one of the more than 1.1 billion people who don't have access to freshwater at all.

Magnetic Particles of Gold, Silver and Copper Produced - 0 views

  • An international team led by Physics and Chemistry teams from the Faculty of Science and Technology at the University of the Basque Country (UPV/EHU) and directed by Professor Jose Javier Saiz Garitaonandia, has achieved, by means of a controlled chemical process, that atoms of gold, silver and copper - intrinsically non-magnetic (not attracted to a magnet) - become magnetic. The article has been published in the February issue of the prestigious international magazine in nanotechnology, Nanoletters (Vol.8, No. 2, 661-667 (2008).

The Green Grid announces technology roadmap | News | ZERODOWNTIME Magazine - 0 views

  •  
    The Green Grid, a non-profit consortium dedicated to advancing energy efficiency in data centers and business computing ecosystems, has announced its technology roadmap and key deliverables for 2007. For the next several months, The Green Grid will focus on data collection through the documentation of existing standards and the evaluation of metrics; data assessment through a market study of current efficiency practices; and technology proposals that outline The Green Grid's recommendations for the future of energy efficient data centers.

Clean Edge - The Clean-Tech Market Authority - Views - 0 views

  • Back in 1998, Forbes magazine ran a story pooh-poohing the solar power industry. The article called the concept of spurring demand to increase production and bring costs down “an error in the history of solar energy” and brushed aside a million solar roofs proposal from then-President Bill Clinton with the line, “The religion of environmentalism dies hard.”

Power outage hits 365 Main data center | News | ZERODOWNTIME Magazine - 0 views

  •  
    This afternoon a power outage in San Francisco affected the 365 Main St. data center. In the process of 6 cascading outages, one of the outages was not protected and reset systems in many of the colo facilities of that building. - DNS servers lost power and did not properly come back up. This has been resolved after about an hour of downtime and may have caused issues for many GNi customers that would appear as network issues

Make: Online : Thorium as the future of nuclear power? - 1 views

  • Interesting article over on Wired about Kirk Sorensen and the community served by his Energy From Thorium blog. To hear these people tell it, thorium fission in fluid fuel reactors offers an idyllic vision of a boundless-energy-from-the-atom type future no one has really believed in since the early 50s. Thorium, reportedly, is abundant, safe, highly efficient as a nuclear fuel, and produces waste that is radioactive only for a few hundred years instead of tens of thousands.

  • CFE operates a total installed capacity of 58.2 GW, of which 964.5 MW is geothermal; a figure that is poised to increase still further.
  •  
    A relatively rare story on geothermal energy. The potential of this technology is largely unknown - estimates vary tremendously. But with a potential to provide baseload electricity, this source may just have a role to play in the wind/PV/CSP electricity system of the future.

European & US Renewable Energy Targets | Renewable Energy World Magazine Article - 0 views

  • Latest data show, however, that in 2010, the indicative targets the member states set themselves for the electricity and transport sector were missed by most member states and the EU overall.
  • 'It is the fifth consecutive year that renewables have accounted for more than 40% of new electricity generating installations,' said Zervos.
  • By 2035, 80% of America's electricity will come from clean energy sources'.

  • The Chilean Agency for Energy Efficiency is developing an energy efficiency labeling system for new vehicles due out in 2011 and will be mandatory starting in September.  (Diario Financiero, 12/16/10)
  • Scientists at the University of Costa Rica are developing solar cells sensitized with dyes from local plants.  Benefits of the cells include its cheaper production price, flexibility and thinness, and ability to produce power with very little light.  However they are not yet as efficient as the present day silicon solar cells. (El Financiero CR, 12/14/10) Mitsubishi Motors will release the first electric car in Costa Rica, called iMiEV.  The car is 100% electric, automatic, is powered by a lithium-ion battery, has room for five people and will cost $61,500.  According to the company, Costa Rica was chosen for car’s release in the Americas due to its environmental record and goal to become carbon neutral by 2021.
