No matter how the U.S. energy portfolio changes, an increasing share of future needs will be met by energy-conversion and energy-demand technologies now in the research or development stage. Some will require substantial improvements—or even research breakthroughs—to have a major impact on our energy budget.
Some options are described below. Whether and to what extent any of these technologies ultimately contributes to changing our energy future will depend on many factors, from advances in technology development to the priorities reflected in government policy.
