"The report begins with a look at the worldwide trends associated with energy consumption. The historical time frame has been expanded from previous reports to incorporate data from 1970. The longer time span provides readers with a better historical context for the projections. The environment remains an important focus internationally as nations attempt to stabilize carbon emissions at their 1990 levels as agreed upon at the June 1992 United Nations Conference on the Environment and Development, held in Rio de Janeiro, Brazil. World carbon emissions attributable to fossil fuels (oil, natural gas, and coal) were computed as part of EIA's[Energy Information Administration] international model, the World Energy Projection System (WEPS), which is described in Appendix B of this report. As is true for energy consumption, the time frame for carbon emissions includes historical data from 1970. The remainder of the report is organized by energy source. Regional consumption projections for oil, natural gas, coal, nuclear power, hydroelectric and other renewable energy (geothermal, solar, biomass, wind, and other renewable sources), and electricity are discussed. Several chapters feature discussions on North America, important regionally because of Mexico's acceptance into the OECD and because of the potential impact of the recent North American Free Trade Agreement."
