4 Environmental Impacts of Renewable Electricity

Fossil-fuel dominated electricity generation in the United States and China has enormous environmental consequences. In 2007, 2.4 billion metric tons of carbon dioxide (CO 2) were emitted from electricity generation in the United States, about 40 percent of the countrys energy-related greenhouse gas (GHG) emissions.In the same year, electricity generation in China produced just over 2
