A recent survey shows that not all Americans are concerned with phasing out fossil fuels in the face of climate change, according to Green Car Reports.

A recent survey conducted by Pew Research Center found that only 31% of Americans believe that fossil fuels should begin to be phased out, while 68% of those surveyed believe the country should continue with a mix of fossil fuels and renewable energy.

Of those surveyed, younger individuals were the most supportive of phasing out fossil fuels. 48% of those in the 18 to 29 age range believe fossil fuels should be left behind, while 52% believe that the U.S. should continue to use fossil fuels alongside other energy sources.

When divided by political party, only 12% of Republicans believe that the U.S. should move past fossil fuels, compared to 48% of Democrats supporting such a move.

Even among Democrats, however, those in older age ranges are not as worried about the effects of fossil fuels as younger individuals. 58% of Democrats aged 18 through 29 approved of phasing out fossil fuels, with 42% of Democrats aged 65 and older expressing the same sentiment.
