The advocacy group Environment Ohio released a study last week that found that improving the energy efficiency of new and existing buildings in the state would reduce the projected energy use of Ohio's buildings 20 percent and would save the average Ohio family of four $340 annually by 2030, according to a press release from the group. The report, "Building a Better America: Saving Energy and Money with Efficiency," says that because "40 percent of the energy used in America goes to heat, cool, and power our buildings," retrofitting and weatherizing existing buildings and constructing new energy efficient buildings in Ohio would prevent emissions equivalent to taking 15 million cars off the road by 2030.
