The results of a 12-year study show that Americans strongly support renewable energy sources, but “are not clear on the costs of providing that power and do not typically want to pay it themselves,” Utility Dive reports. Harvard professor Stephen Ansolabehere presented the results of the study, which began in 2001, at the Energy Policy Institute of Chicago, saying that while Americans understand the relative costs for traditional fuels, they are “way too optimistic about the cost of solar and wind.” The study showed that coal, oil and nuclear power “are particularly out of favor,” while natural gas is viewed as a bridge fuel to greener generation. The U.S. Energy Information Administration projects that total renewables in electricity and heat generation will show 1.8% growth for 2014. The agency expects that in 2015, wind power will contribute 4.7% of total electricity generation, while utility-scale solar generation will average more than 60 GWh per day.
