Ice-Based Airconditioning Takes Off In California
September 26, 2007 03:02 PM - Paul Schaefer, ENN
SAN FRANCISCO - A company that makes an ice-based air-conditioning system is teaming up with a major public utility, PG & E, in California in a $10-million dollar project. The ice-based air conditioner uses cheaper nighttime electricity to make ice and then uses that ice for daytime cooling needs. The units cooling looks almost identical to a standard AC unit. The systems lowers peak daytime demand significantly, shifting the energy load up to 95%. The California Public Utilities Commission says permanent load shifting technologies deliver a number of benefits to both utilities and energy consumers, including added protection against shortages during heat waves and reduced reliance on the construction of new generation plants.
Group Says Germany needs nuclear to meet carbon cut goal
September 26, 2007 02:47 PM - Reuters
BERLIN (Reuters) - Germany can meet its target of reducing carbon dioxide emissions by 36 percent by 2020 only if it keeps nuclear power plants, which are being phased out, German industry group BDI said on Tuesday.
In a study co-authored by consulting firm McKinsey, the BDI found emissions could not be cut by more than 31 percent by 2020, compared with 1990 levels, without retaining atomic power or harming Germany's economy.
Even achieving the 31 percent reduction would need further investment in technology and would raise the cost of cutting carbon dioxide (CO2) emissions up to 175 euros ($246) per CO2 tonne saved, up from the current 20 euros, the BDI said.
Carbon windfall to go to clean energy: official
September 26, 2007 10:36 AM - Reuters
The European Commission wants to back alternative energy like wind and solar with the money it raises from sales of carbon emissions permits, which could reach billions of euros, a senior EC official said on Wednesday.
Brussels is preparing changes to its carbon trading scheme, its flagship climate change policy, in time for a third trading cycle which starts in 2013.
China warns of catastrophe from Three Gorges Dam
September 26, 2007 08:44 AM - Reuters
China's huge Three Gorges Dam hydropower project could spark environmental catastrophe unless accumulating threats are quickly defused, senior officials and experts have warned.
The dam in southwest China, the world's biggest hydropower project, has begun generating electricity and serving as a barrier against seasonal flooding threatening lower reaches of the Yangtze River, Xinhua news agency reported late on Tuesday, citing a forum of experts and officials.
World Energy Revolution Needed For Climate, Says Condoleezza Rice
September 25, 2007 10:04 AM - Timothy Gardner, Reuters
UNITED NATIONS (Reuters) - U.S. Secretary of State Condoleezza Rice said on Monday the world needs a revolution on energy that transcends oil, gas and coal to prevent problems from climate change.
"Ultimately, we must develop and bring to market new energy technologies that transcend the current system of fossil fuels, carbon emissions and economic activity. Put simply, the world needs a technological revolution," Rice told delegates at a special U.N. conference on climate change.
A landmark report by the U.N. Intergovernmental Panel on Climate Change this year said human activities such as burning fossil fuels and forests are very likely causing climate change that will lead to more deadly storms, heat waves, droughts and floods.

Wal-Mart To Push Suppliers On Energy Efficiency
September 24, 2007 10:54 AM -
NEW YORK (Reuters) - Wal-Mart Stores Inc has formed a partnership with the Carbon Disclosure Project to look for ways for its suppliers to better manage their energy efficiency, as part of its environmental push, the company said on Monday.
Under the partnership with the not-for-profit organization, which collects greenhouse gas emissions data from large companies, Wal-Mart will measure the amount of energy used throughout its supply chain, and use the method on a group of its suppliers to look for ways to make procurement, manufacturing and distribution more energy efficient.
Yes, The Internet Saves Energy
September 23, 2007 11:57 AM - Bruce Mulliken, Private Landowner Network
Recently, in this column, I said this, “I don’t think there’s been a study, and I can’t prove it, but I think the Internet is one of the greatest energy saving inventions ever created.”
Well, now there IS a study to back up my claim. The Consumer Electronics Association (CEA (tm)) thinks the Internet saves energy too; and it’s substantial.
The just-released study commissioned by the CEA and conducted by TIAX LLC of Cambridge, Massachusetts, shows that using electronics to telecommute saves the equivalent of 9 to 14 billion kilowatt-hours of electricity per year – the same amount of energy used by roughly 1 million US households every year.
China Could Be Top Wind Market In 3 Years
September 21, 2007 11:55 AM - Emma Graham-Harrison, Reuters
BEIJING (Reuters) - China could become the world's top wind power market in three to five years but will grow faster if it reforms its subsidy system, executives of major wind turbine maker Vestas said on Friday.
Chief Executive Ditlev Engel, in China to open the second and third in a series of seven plants due to come on line by the first quarter of 2008, said he was convinced Vestas could compete with cheaper local rivals on quality.
But the company, the world's biggest wind turbine manufacturer, made its $80 million investment with an eye on both Chinese and export markets. Turbines not sold in China could be integrated into Vestas' global supply chain, he added.
Worldwatch Perspective: The Meaning of $80 Oil
September 21, 2007 07:35 AM - Christopher Flavin, Worldwatch Institute
The price of oil hit its highest level in a quarter-century this week—and is now closing in on the inflation-adjusted record set in 1981. What’s so surprising, though, is not the high price of oil—at over $80 a barrel—but the timing of this price increase. Most economists predict that the world economy will soon cool, and autumn is usually the season when oil prices fall.
