Voters are most likely to believe that solar is the cheapest source of energy today, followed by wind and natural gas. More voters name solar (28%) as the cheapest source of energy today than fossil fuels such as natural gas (17%) or coal (5%). And when asked to identify the second-cheapest source from the list, solar and wind clearly stand apart as the two energy sources that voters believe are most affordable: Solar – 49% in top two Wind – 45% Natural gas – 34% Oil – 15% Nuclear – 14% Coal – 13% Geothermal – 7%. Voters across party lines recognize the cost-effectiveness of solar, but are more divided about wind. Democrats (33%), independents (27%), and Republicans (25%) are all more likely to identify solar as the cheapest form of energy than any other energy source. However, while majorities of Democrats identify both solar (60%) and wind (60%) among the two cheapest forms of energy, Republicans are more likely to choose natural gas (44%) as one of the cheapest forms of energy than to choose wind (32%).
