2050 generation by case

Each of Rocky Mountain Institute’s four scenarios for the future U.S. electricity system (detailed here) will have a very different electricity generation mix.

 

Technology capital cost projections, 2010-2050

In evaluating the future U.S. electricity system, Rocky Mountain Institute created capital cost projections for fossil and renewable generation technologies through 2050. Many newer technologies, such as concentrated solar power, solar photovoltaics, and battery storage, are projected to have rapidly declining capital costs in the next 40 years.

 

U.S. renewable energy potential

Considering budding technologies that could be commercially available in the future, the potential U.S. generation capacity from renewables is overwhelming. Wave and tidal generators, offshore deep-water wind farms, and enhanced geothermal power (which uses the Earth's heat but doesn’t require a natural steam source) are all in development and represent a huge potential energy resource.

 

U.S. installed wind and solar power capacities and projections, 1990–2050

Together, wind and solar will account for 71% of total U.S. installed capacity in 2050 in Rocky Mountain Institute’s Transform case, up from 4.4% in 2010. Along with hydro, geothermal, and biomass, renewables will meet more than 80% of 2050 U.S. electricity demand.
