A new poll shows that while most of those questioned understand effective ways to save energy, they have a hard time adopting them.
Six in 10 say driving a more fuel-efficient car would save a large amount of energy, but only 1 in 4 says that's easy to do.
The poll by the AP-NORC Center for Public Affairs Research also shows that people also are skeptical of carpooling or installing better home insulation, rating them as effective but impractical.
