Converting cow manure into methane and burning that instead of coal could cut greenhouse gas emissions in the U.S. by about 4 percent, according to scientists at the University of Texas at Austin. The researchers tell Discovery News that the plan is a two-for-one win. Switching from coal to cow patties not only cuts the use of fossil fuel, it also keeps methane and nitrous oxide -- two very powerful greenhouse gases produced by the decay of manure -- from entering the atmosphere. Get out the shovels.
