13W LED Bulb Can Replace 100W Incandescent
April 23, 2008 08:58 AM - , MetaEfficient

This 13 watt bulb, the Evolux by EarthLED, is said to be first LED light to be able to replace a 100 watt incandescent. The lifetime of this bulb is rated at over 50,000 hours — which is five times longer than a compact fluorescent bulb. Other advantages of LED bulbs is their ability to brighten instantly, and be switched off and on rapidly without problems. They also contain no mercury. LED-based bulbs do, however, require more energy to manufacture that CFL or incandescents.

Giant British wind farm plans blown away

The Scottish government has rejected plans to build one of Europe's biggest onshore wind farms due what it said was the "significant adverse impacts" on the local environment. Ministers in Edinburgh decided that the 500-million-pound (one-billion-dollar, 625-million-euro) project would have threatened rare and endangered bird populations and damaged peatland on the remote Isle of Lewis, northwest of the Scottish mainland.

Questioning Nuclear Power's Ability To Forestall Global Warming
April 22, 2008 08:59 AM - American Chemical Society

Rising energy and environmental costs may prevent nuclear power from being a sustainable alternative energy source in the fight against global warming, according to a new study. In the article, Gavin M. Mudd and Mark Diesendorf investigate the "eco-efficiency" of mining and milling uranium for use as fuel in nuclear power plants. Advocates of nuclear power claim it has the potential to mitigate global warming. Detractors, however, link it to dangers such as proliferation of nuclear weapons and problems such as permanent disposal of nuclear waste.

Bolivia's Morales says biofuels serious problem to poor
April 22, 2008 08:05 AM - Reuters

UNITED NATIONS (Reuters) - Bolivian President Evo Morales on Monday criticized "some South American presidents" for supporting the use of biofuels, which he said are responsible for high food prices and global hunger. Visiting the United Nations while fighting autonomy referendums called by the opposition at home, the Bolivian president said the increased use of farmland for fuel crops was causing a "tremendous increase" in the price of food -- especially of wheat, which has made bread more expensive.

EU heads for climate talks with China
April 22, 2008 06:53 AM - Reuters

The European Commission's biggest-ever delegation to China heads for Beijing this week, hoping to progress from words to action on China's soaring greenhouse gas emissions and its tense trade ties with Europe. European Commission President Jose Manuel Barroso will have to tread a careful line because he also intends to raise the handling of pro-independence unrest in Tibet and human rights in general in China in the meetings with the country's leadership.

Biofuels won't solve world energy problem: Shell
April 21, 2008 08:20 AM - Reuters

ROME (Reuters) - Biofuels will not solve the world's energy problem, the chief executive of Royal Dutch Shell said on Sunday, amid growing criticism of their environmental and social benefits. The remarks follow protests in Brazil and Europe against fuels derived from food crops. Food shortages and rising costs have set off rioting and protests in countries including Haiti, Cameroon, Niger and Indonesia.

Latin America: Reconciling Oil and the Environment

IPS, 19 April 2008 - Years of public scrutiny, ever-newer technologies, more government regulations, notions of corporate responsibility and the market-driven need for greater efficiency are all factors behind improvements in the environmental policies of Latin America's petroleum industry. "Our line makes it incompatible to exploit the underground riches as long as above ground people are living in poverty," says Juan Bravo, manager of the environmental wing of Venezuela's state-run oil company PDVSA in the Orinoco belt in the southeast.

Oil running out as prime energy source: world poll
April 21, 2008 05:06 AM - Reuters

WASHINGTON (Reuters) - Most people believe oil is running out and governments need to find another fuel, but Americans are alone in thinking their leaders are out of touch with reality on this issue, an international poll said on Sunday. On average, 70 percent of respondents in 15 countries and the Palestinian territories said they thought oil supplies had peaked. Only 22 percent of the nearly 15,000 respondents in nations ranging from China to Mexico believed enough new oil would be found to keep it a primary fuel source.

Aerodynamic trailer cuts fuel and emissions by up to 15 percent
April 18, 2008 09:02 AM - Delft University of Technology

Creating an improved aerodynamic shape for truck trailers by mounting sideskirts can lead to a cut in fuel consumption and emissions of up to as much as 15%. Earlier promising predictions, based on mathematical models and wind tunnel tests by TU Delft, have been confirmed during road tests with an adapted trailer. This means that public-private platform PART (Platform for Aerodynamic Road Transport), has produced an application which can immediately be put into production.

Russia Switches on Gas
April 18, 2008 08:42 AM - , Global Policy Innovations Program

As the European Union works toward meeting its obligations to reduce greenhouse gas emissions, switching from dirty, carbon-intensive coal to cleaner-burning natural gas has become a popular measure. At first glance, this makes perfect sense: Coal, particularly the kind still left in places like Germany, is highly polluting. Although widespread adoption of renewable energy is the ideal solution, wind, solar, and geothermal still have a ways to go before meeting European needs.
