The Obama administration has proposed tighter restrictions on carbon dioxide emissions which critics believe will discourage construction of new coal power plants. Several states that rely heavily on the coal industry are challenging the new rules, but a majority of voters nationwide favor them. Most recognize, however, that the new rules will drive up energy costs. The latest Rasmussen Reports national telephone survey of Likely U.S. Voters shows that 53% favor new environmental regulations that place stricter limits on carbon dioxide emissions from new power plants. Twenty-nine percent (29%) oppose the new regulations, and 18% are not sure about them.
