Divorce is on the rise around the world. Even in China, where divorce hasnít been common, the number of divorced couples surged from 1.6 million in 2004 to 1.9 million in 2006. In Ecuador, Greece, and the U.S., the number of extra households due to divorce increased dramatically from 1970 to 2001.
Divorced households use more space, energy, and water per person than married households. In the U.S., if resource use efficiency were the same in divorced households as in married households, then US$7 billion in electricity and almost US$4 billion in water could have been saved in 2005. In the following 12 countries, there was a total of 7.4 million extra households(1) as a result of divorce between 1999-2002.
