  • Legal lookout: EPA responds to coal ash release

    Once again, it took a major catastrophe to wake up industry and regulators to a problem that should have been addressed long ago. Dec. 22, 2008, was a nightmare for federal and state regulators, electrical utilities, and most particularly the residents of Kingston, Tenn. On this day, approximately 5.4 million cubic yards (or 1.1 billion gallons) of coal ash from the Tennessee Valley Authority ...

  • Photosynthetic pigment concentrations, gas exchange and vegetative growth for selected monocots and dicots treated with two contrasting coal fly ashes

    There is uncertainty as to the rates of coal fly ash needed for optimum physiological processes and growth. In the current study we tested the hypothesis that photosynthetic pigments concentrations and CO2 assimilation (A) are more sensitive than dry weights in plants grown on media amended with coal fly ash. We applied the Terrestrial Plant Growth Test (Guideline 208) protocols of the ...

  • EPA targets electric utilities - the agency steps up efforts to manage coal ash damage

    Approximately 5.4 million cubic yards, or 1.1 billion gallons, of coal ash from the Tennessee Valley Authority (TVA) plant near Knoxville, Tenn., in December 2008 flooded some 300 acres of land, damaging property, polluting waterways, and killing fish. TVA will likely spend more than $500 million and perhaps as much as $1 billion dollars on the cleanup, says the U.S. Environmental Protection ...

  • Possibility of biomass gasification in tea manufacturing industries in Assam, India

    Tea manufacturing industries in India use natural gas, tea drying oil, wood, and coal for process heat. India is the second largest producer of tea [(1,137.07, China 1,761.00) million kilogram] in 2012. About 0.6–1.2 kg of coal is required to produce one kilogram of dried tea with average moisture of 2.5–3 percentage (w.b.). Biomass gasification is an established renewable energy technology for ...

  • New energy economy emerging in the United States

    As fossil fuel prices rise, as oil insecurity deepens, and as concerns about climate change cast a shadow over the future of coal, a new energy economy is emerging in the United States. The old energy economy, fueled by oil, coal, and natural gas, is being replaced by one powered by wind, solar, and geothermal energy. The transition is moving at a pace and on a scale that we could not have ...

  • What will it take to integrate renewables into the power grid? Ask a bicyclist.

    When it comes to fitting into the current system, bike commuters and electrons have a lot in common. There’s nothing quite like biking down clogged city streets, weaving in and out of traffic. For short distances, it’s faster than driving. It’s liberating. It’s fun. It also makes it painfully clear that most roads ...

  • Is nuclear power our energy future — or a dinosaur in a death spiral?

    Identical data yield drastically different conclusions about the role nuclear will play in meeting climate goals. Nuclear power is dead. Long live nuclear power. Nuclear power is the only way forward. Nuclear power is a red herring. Nuclear power is too dangerous. Nuclear power is the safest power source around. Nuclear is nothing. Nuclear is everything. It is now generally agreed ...
