Apartments are not only smaller and more fuel-efficient to heat and
cool,they also tend to be located near or in metro centers. That
means apartment dwellers are more likely to use public
transportation and less likely to drive long, carbon-burning
distances to work.
For all the advances in energy-efficient home design, it still requires
more energy to build a home from scratch than to move into an
existing one. From transporting materials to powering saws and
drills, construction is energy-intensive. If you want to save money
on utility bills, consider retrofitting an older home with new insulation,
low-flow shower heads and faucet aerators.
