This visualization, provided by National Renewable Energy Laboratories (NREL), shows the projected expansion of renewable technologies in the U.S. over time. This map tracks solar, wind, geothermal, hydro, bio-power, concentrated solar power (CSP) and nuclear/fossil fuels to show how renewable technologies compare to their higher-polluting counterparts from today until the year 2050.
The color of the circles represents the various technologies installed and circle size represents the nameplate capacity of the generation technology installed.
The map gets evermore colorfully as it approaches the year 2050. Certainly an encouraging sign.
