I believe that republicans tend to support renewable sources of energy as on the political spectrum there is support polices that aim to the use of renewable energy sources. There was also a known report from the Yale program for the communication regarding climate change and this report surveyed around 1,000 registered voters in America and they found out that 95% of democrats and around 70% of republicans were in favour of new polices requiring it to be necessary to utilities to produce all of the electricity from either renewable or clean sources by 2050. Hope this helped !
