Lisa Margonelli spells out the benefits of mobile homes:
An elaborate 2012 report published by ROC USA and underwritten by HUD found that mobile homes use, on average, far less energy and water than conventional homes or condos (the mobile homes in the study were 940 square feet, larger than those at Pismo Dunes). While models built before 1976, when federal regulations kicked in, sometimes have exorbitant utility bills, newer models made to Energy-Star efficiency standards can reduce the combined costs of electricity, gas, and water to well below $1,000 a year, even in the hottest and coldest parts of the country. And manufacturing the homes in factories cuts construction waste by 30 percent. The efficient layout of a mobile-home park helps conserve water and reduces storm runoff. And in some locations, residents are able to share vehicles, or get around without them, which saves money.
