Fig. 4: Differences in the proportion of homeowners who are registered Democrats between households that took advantage of the incentive program to install solar PV and randomly selected households from the same district who did not.
From: Assessing potential for policy feedback from renewable energy incentive programs
The differences are presented separately for (a) U.S. Congressional districts, (b) NY State Assembly districts, and (c) NY State Senate districts. Positive differences indicate that PV-adopting households had higher proportions of homeowners registered as Democrats and negative difference indicate that non-adopting households had greater shares of Democrats. The color of each bar corresponds to the party of the local elected official (Republican = red; Democrat = blue).
