"Here's an opportunity to wisely spend some of the $100 billion that Secretary of State Hillary Clinton promised at Copenhagen to cut the greenhouse gases of developing nations by aiding in the development of renewable energy infrastructure to by-pass fossil fuel dependence.
Apparently one in four Chinese cities and seven out of 10 counties are without sewage-treatment plants, according to the People's Daily. While there are many ways to treat sewage or municipal waste; one of the newest is the use of municipal solid waste to make renewable energy.
Converting waste to energy is done in several ways. One is making bio-gas from sewage (human or animal) to run gas-turbine driven electric power plants.
Another is to create a biofuel, such as that used by nearly every vehicle in Sweden's fifth largest city Linkoping. Greenhouse gas emissions there were reduced as much as 90% with the technology. It helped Sweden achieve a 9% below-Kyoto emissions cut with simultaneous 44% economic growth.
This presents an opportunity to kill two birds with one stone; by building the infrastructure in the developing world that uses municipal solid waste to make renewable energy. This would cut the greatest source of the rise expected in greenhouse gas emissions from fossil fuel use in the next decades: from fast-developing nations like India and China."
