Title :

Fig. 2. Filling the Technology Gap

Description :

Based on technical and economic analyses, this figure compares two hypothetical scenarios for energy demand and supply growth over this century: (1) The IPCC/MiniCAM B2 scenario (upper curve), which assumes a relatively unchanged energy mix, is not carbon constrained; (2) A carbon-constrained scenario that stabilizes atmospheric concentrations of CO2 at 550 ppm (family of curves below) was chosen to illustrate the types of changes in energy mix that might occur. An acceptable level of atmospheric CO2 is still to be determined. U.S. energy strategy is based on technology development to provide multiple options to fit various national and global contingencies, market forces, and the ultimate stabilization of carbon emissions to near zero. This combination of technologies includes energy-use reduction, new and expanded nonemitting energy sources, and carbon sequestration. To meet these goals in the scenario illustrated here, analysis indicates that by the end of the century biotechnology sources of energy must grow to roughly equal today’s fossil-fuel usage.
