Power plants play a huge role in emitting pollutants that make up the ozone. This pollution browns and blackens our horizons. We call it smog. Smog has been linked to premature deaths, thousands of emergency room visits, and tens of thousands of asthma attacks each year. Pollution in the ozone is particularly dangerous to small children and the elderly, who are often warned to stay indoors on days with poor air quality due to pollutants.

In 2001, energy companies across the United States were busy drawing up plans for about 150 new coal-fired power plants. That year, Sierra Club launched its Beyond Coal campaign.
Today, the campaign celebrated its 100th defeat of a proposed coal plant.
“Coal mining is literally blowing the tops of mountains in Appalachia, coal burning is literally heating up our planet, spewing mercury across our landscape, and exposure to coal ash is wreaking havoc on streams and rivers across this country. So in every phase of the lifecycle, coal is filthy business,” Sierra Club campaign director Bruce Nilles said in announcing the milestone.
“We have persuaded the developers, the investors and the decision makers that we can do better than building dirty coal-fired power plants.”
World wide, 75 percent of human exposure to mercury is from the consumption of marine fish and shell fish. In the U.S., about 40 percent of all human exposure to mercury is from tuna harvested in the Pacific Ocean, according to Elsie Sunderland, a coauthor of the recent US Geologic Survey study.Data used in this study comes from one of 15 (so far) research cruises that are part of a much larger, international project called CLIVAR; the Climate Variability (CLIVAR) Repeat Hydrography/CO2 research program.
Data analysis of the water samples indicated that total mercury levels in the North Pacific Ocean water have risen about 30 percent over the last 20 years.

I was struck by the trash talk spotlight on Green is Sexy this month with Verus Energy Ltd. Co-Founders Tim Jervis and David Diracles because they truly understand that the global energy generation infrastructure is requiring colossal changes to sustain the planet.
Verus Energy is a new form of development company that focuses on building renewable power plants that use waste as the feedstock: “In the same way that a property developer might develop a new residential or commercial property, Verus develops a power plant. Between the core team at Verus and our strategic partners, we can design, build, construct, and operate power plants that use waste rather than fossil fuels as the source of energy.” Jervis and Diracles explain.
Verus states on their website that they are out to change the way power plants work. Their mission is to help the UK (and soon the US) address waste and energy challenges by developing clean and efficient energy from waste plants. Energy from waste encompasses many processes where trash is converted into electricity, heat, or transport fuel. On top of providing a clean and secure source of energy, the process provides an environmentally friendly alternative to dumping waste in landfill.
Instead of polluting the air with the (traditional power generating) burning of waste for fuel, they are creating much cleaner trash power with anaerobic digestion and pyrolysis…
Editor’s Note : This is a guest post from William Ellard, an economist specializing in energy and renewable energy markets. He is currently working with national solar energy firms to bring distributed solar power to municipalities in the American Southwest.
During a recent work meeting with the Western Renewable Energy Zones Initiative, it became clear that the recent push for renewable energy in the western US has major wildlife and environmental implications. As an alternative energy economist, my contribution in the meeting was to present some of the new solar energy technologies and explain how distributed solar could be deployed without disturbing wildlife ecosystems.
Dale Hall, Fish and Wildlife Service Director, told the Associated Press on Tuesday that the short time frame for processing the comments was requested by Interior Secretary Dirk Kempthorne and, indeed would set a record. Usually the review process takes months.

New ideas for reducing CO2 seem to be popping up all the time. The latest scheme for getting rid of the greenhouse gas comes from Stanford Professor Brent Constanz. The Geological and Environmental Sciences Professor has invented a new type of cement that is carbon neutral—a huge innovation for a material whose production process normally spews vast amounts of CO2 into the atmosphere.
Not only is Constanz’s cement carbon neutral, but it also sequesters CO2 emitted from power plants.
