Procrastinate no longer. We give you 29 ideas for saving energy and water around your home that involve little or no installation and barely a bump in your routine. Individually, they cost less than $100. Collectively, they can save hundreds of dollars a year in household energy bills, thousands of gallons of water and thousands of pounds of carbon-dioxide emissions. You have every reason to follow these tips and not a single reason to ignore them. Get cracking, folks. How we calculated the savings Many of these calculations rely on figures provided by Jeffrey Langholz and Kelly Turner in You Can Prevent Global Warming (and Save Money!)
