There has been a modest decline since 2008 in support for requiring better fuel efficiency for vehicles, increasing federal funding for research on alternative energy and spending more on mass transit. A majority of Republicans continue to support these policies, but fewer do so now than in 2008 or 2006. In the current survey, 73% of Republicans favor requiring better fuel efficiency for cars, trucks and SUVs, down from 86% two years ago and 85% in February 2006. Similarly, 64% of Republicans favor increasing federal funding for research on wind, solar and hydrogen technology, down 21 points from two years ago. Republican support for spending more on subway, rail and bus systems has also declined — from 65% in 2008 to 55% now. Opinion among independents also has shifted. About three-fourths (76%) of independents favor higher fuel efficiency standards, down from 87% in 2008 and 2006. Similarly, 72% of independents support increased funding for alternative energy, down 13 points since 2006. And somewhat fewer favor spending more on mass transit (61% now, 74% in 2008). By contrast, support among Democrats for increased spending on alternative energy and mass transit and better fuel efficiency requirements has remained steady or increased slightly over the past few years. In 2006 and even 2008, the partisan differences in opinion about these policies were quite small, but now the gaps between Republicans and Democrats are 16 points or more. There has been little change in views about nuclear power over this time; 45% favor promoting the increased use of nuclear power now, virtually unchanged from 2006 when 44% supported this. Far more Republicans (57%) than Democrats (36%) or independents (45%) support the increased use of nuclear power.
