Carbon Offsets: Deal or No Deal?

Carbon Offsets: Deal or No Deal?

Carbon Offsets are responsible for a huge debate within the environmental and sustainability sectors. Do they help? Are standards adequate to achieve the goal of the scheme? Sould they be banned? This article presents an arguement in support of carbon offsetting, covering the basic theory and issues behind the idea.

New Study Finds Many Biofuels Come with a Large Carbon Footprint

A new study by the Marine Biological Lab (MBL) of Woods Hole Oceanographic Institution (WHOI) has reported that biofuels that displace food crops may have a much bigger carbon footprint than previously thought. MBL senior scientist Jerry Melillo and his colleagues at the MBL have reported that carbon emissions from land-use change caused by the displacement of food crops and pastures by a global biofuels program may be twice as much as the emissions from lands directly devoted to biofuels production.

Incentives to Use Less Energy

With global eco awareness expanding on climate issues, it is not a surprise to many that the fastest growth in CO2 levels has occurred in the last 10 years. Studies indicate that electricity generation and consumption is the largest contributor and is increasing faster than any other energy sector. However, efforts to manage electricity show the slowest decline in emissions progress.

Retrofitting Our Way Back to Economic Recovery

This country’s 130 million homes together generate more than 20% of the nation’s carbon dioxide greenhouse gas emissions. This is one of the most significant contributing sources in the country to global warming. Existing techniques and technologies in energy efficiency retrofitting can reduce home energy use by up to 40 percent per home on average which would also lower our national greenhouse gas emissions by 160 million metric tons annually by the year 2020. In addition doing so would reduce home energy bills by $21 billion a year and over time these savings would more than pay for the high up-front costs for energy efficiency retrofitting.

The Low Down on (Green) Air Travel

It’s no secret that air travel is hard on the environment; but it’s also one of the key ingredients to a robust global economy. The World Intellectual Property Organization says that air travel accounts for 35 percent of goods traded internationally (by value) and over 40 percent of international tourism. On the upside, aviation generates 5.5 million jobs and contributes over $400 billion to global GDP. On the downside, aviation also accounts for roughly 13 percent of global transport emissions and 2 percent of global carbon dioxide emissions.

Will Big Oil Become Big Algae? ExxonMobil and Chevron Invest in Synthetic Biology

On August 11, the Financial Times reported on the promise of “synthetic biology,” including the development of algae that generates biofuels. In July, ExxonMobil entered into a $600 million venture with Synthetic Genomics, a firm founded by biotech pioneer Dr. Craig Venter. “Synthetic Genomics has already engineered strains of algae that secrete oil from their cells,” writes the FT’s Clive Cookson. Will oil companies transform themselves into algae companies? Or, a few years from now, could the makers of “Who Killed the Electric Car?” film a sequel about algae?

Green Computing and Smart Grid Technologies To Play Huge Role U.S. Energy Efficiency Gains

Energy solutions that are described as “smart”, from smart buildings to smart appliances to the Smart Grid and semiconductors are projected to make a huge impact on the United States’ ability to significantly reduce our spending and use of energy. Between now and 2030, electricity bills could be reduced by $1.3 trillion assuming that the right investments and policies are in place, eliminating the need by the end of the period for 296 power plants with the use of the semiconductors used to improve the software capabilities of the technologies we use on a daily basis, says a report released recently by the American Council for an Energy-Efficient Economy (ACEEE).

Energy Sec. Chu Calls for Cleantech Revolution To Create Green Jobs, Rebuild Our Economy, and Save The Environment

Last week, at the National Clean Energy Summit 2.0 in Las Vegas, Energy Secretary Chu called for a revolution, “a second industrial revolution.” The first industrial revolution came with a “carbon dioxide cost” but “in the next industrial revolution, we must develop technologies that will enable us to get the energy the world needs to grow and prosper but “essentially reducing and eliminating the carbon dioxide,” he said. Chu said the United States has the greatest research and development centers in the world in universities, national labs and the private sector. “Once we get this great invention machine geared and going we’d be invincible. But the only trouble is, let’s get it going.”

Climate Change Denial and Energy Ignorance: A Pair of Albatrosses that Prevent Needed Policy Changes

This, the fifth article in the series The Two-Headed Dragon ~ Energy/Water/Food Scarcity and Climate Change. Top Ten Policies that Feed it, and Two New Technologies that Could Enable us to Slay It and Save the Planet discusses why the short term mindset that prevails in our culture is preventing us from addressing the existential problems of climate change and rapidly disappearing fossil energy reserves. It touches on our nation’s irrational tax code, which provides a powerful incentive for wasteful practices and continued reliance on fossil fuels. It also suggests that the profound ignorance in energy matters is one of the key reasons why we have such poor energy policy, suggesting that our politicians should attend an energy boot camp and learn the fundamentals of energy.
