I can see clearly now, the smoke is gone. Or prevented. Thanks to the Sierra Club, who celebrated a landmark in the fight against coal today. Thanks to advocacy in favor of ending coal, Intermountain Power decided to pull the plug on a coal plant in Delta, Utah, making the 100th plant to be either abandoned or prevented since the beginning of the 2001 coal rush.

The Delta plant “would have burdened Utah with more coal-burning pollution,” said Wayne Hoskinson, chairman of the Utah Chapter of the Sierra Club. “This opens the door for additional renewable projects, like the Milford wind development, allowing the state to still be an exporter of energy without the cost of worsened air quality and more mercury pollution.” It is exactly this shift from coal to renewables that the Sierra Club has been advocating since it began its Beyond Coal Campaign.

The abandonment of the Delta plant comes in the wake of Los Angeles Mayor Antonio Villaraigosa’s announcement last week that Los Angeles would be coal free by 2020 and is reason to celebrate. “Stopping one hundred coal plants is a huge milestone in our fight to end global warming,” said Bruce Nilles, Director of the Sierra Club’s Beyond Coal Campaign.

More than 100 Greenpeace activists from around the world have occupied four coal-fired power stations across Italy (live stream and twitter feed).  The action is aimed at forcing the Heads of State to take leadership on climate change as top politicians from the world’s most powerful nations arrive at the G8 Summit today.

Early this morning, an international team of Greenpeace activists occupied key positions at the site of four current and planned Italian power stations in Brindisi, Marghera (just outside of Venice), Vado Ligure, (near Genoa) and Porto Tolle.

The Brindisi facility is Italy’s biggest coal-fired power station and the country’s largest single C02 polluter. The Greenpeace sabotage operation will entail blocking the coal conveyor belts and preventing coal from going into the plant.

Coming in at second place in the world in energy consumption - second only to the United States - the People’s Republic of China (PRC), the world’s most populated nation, is looking for ways to cut down on greenhouse gas emissions and shift to renewable energy. This desire to increase renewable energy sources and cut greenhouse gases has led the PRC to promote private investments in renewables.

Such promotion has led to a recent investment by The Asian Development Bank (ADB), which will partly finance a $73 million wind farm in the Inner Mongolia Autonomous Region. ADB will be investing $24 US (164 million CNY) in Datang Sino-Japan (Chifeng) Renewable Power Corporation, a joint venture between state-owned China Datang Corporation and Japan’s Kyushu Electric Power Company, Sumitomo Corporation and Sumitomo Corporation (CHINA) Holdings. Such a venture will be ADB’s first private sector wind farm investment in the PRC.

There’s a bit of money, too, totaling about $100,000 from the federal stimulus package, aka the American Recovery and Reinvestment Act of 2009.

The Great Lakes Commission has been granted $99,740 to develop a set of “Best Practices to Accelerate Wind Power in the Great Lakes and Beyond.”

The end result will be a guide to what works and what doesn’t when it comes to protecting the environment, being sensitive to community concerns and … building wind turbines in the water.

Earlier this week, CleanBoard started talking publicly about what it calls “the most environmentally friendly drywall on earth.” That’s quite a claim, but there might be something to it: the drywall will be produced in a solar-powered factory and made from coal-fired power plant residue.

Coal plants collect the “fly ash,” a byproduct of burning coal for fuel, in order to bury or recycle it later. The scrubbers collecting the ash are in place to reduce emissions so that plants can produce “clean coal.” Disasters like this certainly call into question how clean that process really is.

Rainforest Action Network has declared yesterday and today, November 15th, as national days of protest against Citibank and Bank of America for their consistent support of the coal industry and its impact on global warming.

Coal power plants can utilize solar to produce 15%-60% of the electricity. A higher quantity is possible, but requires significantly more modifications to be made to the coal boilers.

Solar Interface

Mirrors, called fresnal reflectors capture the sun’s rays and heat water in the tube above. Steam lines deliver the solar energy to the adjacent coal power plant where existing coal turbines are used to produce an electric current.

The ideal situation for retrofitting a coal power plant with solar includes:

Many experts are saying yes. Professor David Rutledge of CalTech believes that world coal reserves are grossly overstated and could be substantially exhausted this century. This is in stark contrast to earlier forecasts.

Coal Reserves Inflated

In the last 20 years, official coal reserves have fallen by 170 billion tons. To put this number in perspective, global coal consumption in 2007 was 6 billion tons. Reserves figures are dropping far more quickly than actual extraction.

One of the most common arguments against large-scale use of renewable energy is that it cannot produce a steady, reliable stream of energy, day and night. Ausra Inc. does not agree. They believe that solar thermal technology can supply over 90% of grid power, while reducing carbon emissions.

“The U.S. could nearly eliminate our dependence on coal, oil and gas for electricity and transportation, drastically slashing global warming pollution without increasing costs for energy,” said David Mills, chief scientific officer and founder of Ausra.

You may be wondering, how will we have electricity at night or during cloudy weather?
Will we use large banks of batteries or burn candles?

The ability to utilize solar thermal technology after the sun sets is made possible by a storage system that is up to 93% efficient, according to Ausra’s executive vice president John O’Donnell.

The United States Air Force is well on their way to becoming coal-powered. On Monday, the USAF carried out a transcontinental test flight using a 50-50 blend of standard jet fuel and coal-based ’synfuel’.

“The Air Force is taking a leadership role in testing and certifying the use of synthetic fuel in aircraft,” Secretary Wynne said. “We’re working very closely with our Army and Navy colleagues to ensure that this fuel is capable of operating in all of our aircraft. This is especially important because JP-8 military jet fuel is commonly used in the battlefield by the Army and Marines tactical vehicles and generators, as well as our respective aircraft.”

While synthetic fuel has the capacity to reduce our dependence on foreign oil, it could also double CO2 emissions produced by military flight. At the time of this writing, synfuel is made via Fischer-Tropsch process from either coal or natural gas to produce a somewhat cleaner burning but extremely greenhouse-gas intensive product.
