If we all lived in homes near public transportation such as trains or buses, we could reduce our total energy costs by up to 50 percent, according to a new study from the U.S. Environmental Protection Agency.
According to the EPA study, our homes and our vehicles account for 70 percent of our total energy expenditures, and 62 percent of our greenhouse gas emissions. But if we all lived near (and were therefore more likely to take) public transportation, we could reduce our costs (and our dependency on fossil fuels) dramatically.
The study found that a single-family home located near public transport could 39 percent less energy. If the home were also energy-efficient and its owners used an energy-efficient car, the savings could be 54 percent.
The savings add up even more for multifamily homes, which could reduce their costs by 64 percent.
The EPA report provides opportunities for communities to foster development that would make these savings possible by making appropriate public investments in transportation alternatives, including transit; adopting zoning that encourages attached or multifamily housing, particularly near transit; and adopting building codes and incentives to encourage more energy-efficient construction.
