The drive to extract and store CO2 from coal-fired power plants is gaining momentum, with the Obama administration backing the technology and the world’s first capture and sequestration project now operating in the U.S. Two questions loom: Will carbon capture and storage be affordable? And will it be safe?

The debate surrounding global climate change has been a very hot button issue for the past few years. In most cases the average person doesn’t know enough about the science behind this issue to make an informed decision. The fact is that climate change will become a major issue within the next two decades and will have a host of environmental as well as economic impacts in the United States. Climate change will play a major role in the way our economy functions as well as the way our legislators make decisions.
The U.S. Environmental Protection Agency (EPA) has recognized eight landfill methane capture projects for innovations to reduce their emissions of methane – a potent greenhouse gas — and in the process recover renewable energy. The Landfill Methane Outreach Program (LMOP) gives these awards to acknowledge excellence in innovation, successful project development that achieves both environmental and economic benefits.
2010 will see extended range plug in hybrids — as well as all electric vehicles start to hit the road in significant numbers. The plugin hybrid electric vehicle (PHEV) is a primarily an electric vehicle with a small non-electric motor to extend their range; it is more of an electric vehicle and less of a gas powered vehicle than current hybrids. This post examines some of the main players in this emerging electic vehicle sector.
Anaerobic Digestion is one of the more promising biological technologies for sustainable waste management and has the potential to turn a large and worsening agro-headache into a growing opportunity for sustainable farming. It can extract useful biogas energy and high quality fertilizer from manure and other problematic agro waste products while also reducing the air and water pollution and emissions of greenhouse gases from a farming operation. Anaerobic Digestion harnesses natural living biological processes to maintain the natural carbon cycle and extract useful energy and fertilizer byproducts from what had been problematic waste streams. It is well suited for many types of farming operations and is an important sustainable farming practice.
UPDATE: Department of Agriculture announced a public/private partnership to help spread the use of anaerobic digester technology in dairy operations with the goal of reducing their greenhouse gas emissions by 25% by 2020.
In a major new announcement, the U.S. Environmental Protection Agency (EPA) has concluded that greenhouse gases (GHGs) threaten the public health and welfare also explicitly stating that GHG emissions from on-road vehicles contribute to that threat. This conclusion by the EPA has been reached after a thorough examination of the scientific evidence and careful consideration of public comments.
The U.S. Department of Energy (DOE) has announced $104.7 million in funding for seven new research and testing facilities located in DOE national laboratories. The announced projects will support the development and improvement of clean energy and efficiency technologies that are in the US strategic national interest. The new funding is supporting research in techniques to reduce the cost to manufacture carbon fiber on a large scale; finding ways to improve efficiency and lower costs for car batteries; and for developing net-zero energy building technologies.
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.
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.
