U.S. CO ₂ emissions from coal could eliminate in 20 years, experts say

ScienceDaily (May 2, 2010) – the USA could complete carbon dioxide emissions from coal-electric Kraftwerke-- a decisive step for controlling global warming - 20 years using technology already exists or within a decade after a group of scientists, engineers and architects commercially available could be.

This is the conclusion of an article online, along with a news article on the subject in the American Chemical Society's semi-monthly journal environmental science & technology (ES & T) published. both are planned for the June print edition of the ES & t.

Pushker Kharecha and Kollegen--by the NASA Goddard Institute for space studies, Columbia University Earth Institute, the national renewable energy laboratory and 2030 Inc. / Architecture 2030--say that the global climate change problem is manageable only if the company quickly employs carbon dioxide emissions from the combustion of coal in electrical power plants.

"The only practical way to a planet, the similar to the world of the nearby (today) to preserve with relatively stable coastlines and conservation of the species, it is rapidly, phase out coal emissions and prevent emissions from unconventional fossil fuels such as oil shale and tar sands" tell.

The authors describe this exit strategies possible box.you include the abolition of subsidies for fossil fuels; putting increasing prices on carbon emissions; substantial improvements of power transmission and the energy efficiency of homes, commercial buildings and equipment; replace coal with biomass, geothermal, wind, Sun and third-generation nuclear power; and after successful demonstration at commercial scales, deploying advanced (fourth generation) nuclear power plants; and carbon capture and storage on remaining coal plants.
