ecological footprint http://www.ecouncil.ac.cr/rio/focus/report/english/footprint/introduction.htm This"Footprints of Nations" report compares the ecological impact of 52 large nations, inhabited by 80 percent of the world population. It also shows to what extent their consumption can be supported by their local ecological capacity. One key finding is that today, humanity as a whole uses over one third more resources and eco-services than what nature can regenerate. In 1992, this ecological deficit was only one quarter.

renewable resources http://www.eia.doe.gov/cneaf/electricity/pub_summaries/renew_es.html Renewable resources (solar, wind, geothermal, hydroelectric, biomass, and waste) currently provide nearly 12 percent of the Nation's electricity supply. Almost 10 of this 12 percent is provided by hydroelectric resources alone. Biomass and municipal solid waste (MSW) together contribute more than 1 percent. All other renewable resources, including geothermal, wind, and solar, together provide less than 1 percent of the total.
