Report on Advancing Energy Efficiency in Data Centers.

October 22, 2008 By: George Category: Climate, Computing No Comments →

The U.S. Department of Energy (DOE) and U.S. Environmental Protection Agency (EPA) have released the report, “Energy Efficiency in Data Centers: Recommendations for Government-Industry Coordination,” which details the discussions and recommendations covered during a national strategy workshop on July 8, 2008. The workshop, convened by DOE and EPA, gathered representatives from industry, utilities, associations, and NGOs to identify the next steps for public and private collaboration toward advancing toward the goal of improved energy efficiency in data centers.

U.S. data centers consume a growing portion of the U.S. energy/electricity supply due to growing demand for the services they provide. Data centers used 61 billion kilowatt hours of electricity in 2006, representing 1.5% of all U.S. electricity consumption—double the amount consumed in 2000. Based on current trends, energy consumed by data centers will continue to grow by 12% per year.

Report Says Emerging Green Economy Could Create Tens of Millions of New “Green Jobs”.

October 16, 2008 By: George Category: Climate, Renewable Energy, Trends No Comments →

The new report entitled Green Jobs: Towards Decent work in a Sustainable, Low-Carbon World, says changing patterns of employment and investment resulting from efforts to reduce climate change and its effects are already generating new jobs in many sectors and economies, and could create millions more in both developed and developing countries.

Green jobs reduce the environmental impact of enterprises and economic sectors, ultimately to levels that are sustainable. The report focuses on “green jobs” in agriculture, industry, services and administration that contribute to preserving or restoring the quality of the environment. It also calls for measures to ensure that they constitute “decent work” that helps reduce poverty while protecting the environment.

Among other key findings in the report:


The Economics of Ecosystems and Biodiversity.

October 12, 2008 By: George Category: Climate, Trends No Comments →

Human well-being is dependent upon “ecosystem services” provided by nature for free, such as water and air purification, fisheries, timber and nutrient cycling. These are predominantly public goods with no markets and no prices, so their loss often is not detected by our current economic incentive system and can thus continue unabated. A variety of pressures resulting from population growth, changing diets, urbanization, climate change and many other factors is causing biodiversity to decline, and ecosystems are continuously being degraded. The world’s poor are most at risk from the continuing loss of biodiversity, as they are the ones that are most reliant on the ecosystem services that are being degraded.

At the meeting of the environment ministers of the G8 countries and the five major newly industrializing countries that took place in Potsdam in March 2007, the German government proposed a study on ‘The economic significance of the global loss of biological diversity’ as part of the so-called ‘Potsdam Initiative‘ for biodiversity.


DOEs Energy Savers Website Helps Consumers Stay Warm, Save Money.

October 06, 2008 By: George Category: Climate, Renewable Energy No Comments →

On October 1, the first day of Energy Awareness Month, the U.S. Department of Energy (DOE) launched the Stay Warm, Save Money campaign on the website; this educational outreach campaign aims to help consumers be more energy efficient and save on energy costs.  The information focuses on proactive ways to implement simple, cost-effective, energy saving solutions for both homes and businesses this winter and will expand to year-round home energy efficient tips.

Google’s “Clean Energy 2030” plan.

October 05, 2008 By: George Category: Climate, Renewable Energy No Comments →

Google’s “Clean Energy 2030” plan as it’s described by Jeffery Greenblatt,’s climate and energy-technology manager, proposes to wean the U.S. off of coal and oil for electricity generation by 2030 by relying on power from wind, nuclear and geothermal sources instead. It also calls for raising the standard car fuel efficiency from 31 mpg to 45 mpg and increasing usage of plug-in hybrids and pure electric cars.

It’s an ambitious plan, to say the least. Expensive too–a jaw-dropping $4.4 trillion dollars. But Google believes it could generate net savings of $1 trillion over its 22-year span.

Google Drills $10.25M into Geothermal Technology.

August 19, 2008 By: George Category: Climate, Renewable Energy No Comments →

Today, announced more than $10 million in investments and grants in Enhanced Geothermal Systems (EGS) technology. EGS expands the potential of traditional geothermal energy by orders of magnitude. The traditional geothermal approach relies on finding naturally occurring pockets of steam or hot water. The EGS process, by comparison, replicates these conditions by fracturing hot rock, circulating water through the system, and using the resulting steam to produce electricity in a conventional turbine.

EGS has the potential to provide clean renewable electricity 24/7, at a cost cheaper than coal. The ability to produce electricity from geothermal energy has been thought exclusive to locations such as California and Iceland. However EGS could allow us to harness the heat within the earth almost anywhere. To see the massive size of the US geothermal resource accessible by EGS, check out the Google Earth layer.

EGS is heating up around the world. Australia, Germany, and the European Union are currently leading the technology and commercialization race. All 50 U.S. states, Europe, Russia, China, and India all have substantial thermal resources accessible by EGS.
A recent report by MIT on EGS estimated just 2% of the heat 3 – 10 km below the continental United States is more than 2,500 times the country’s total annual energy use

China’s Clean Revolution.

August 13, 2008 By: George Category: China, Climate, Renewable Energy No Comments →

China is already the world’s leading renewable energy producer (In terms of installed renewable capacity, China leads the world, reaching 152 Gigawatts in 2007) and is over-taking more developed economies in exploiting valuable economic opportunities, creating green-collar jobs and leading development of critical low carbon technologies, says a new report to be published by The Climate Group.

The report – China’s Clean Revolution – shows that China’s transition to a low carbon economy is well underway, led by supportive government policies which are not only driving innovation in low carbon technologies but also diverting billions of dollars of investment into energy efficiency and renewable energy.
