“The biggest opportunity in water, isn’t in water: it’s in information,” what he’s talking about is waste. Right now, in America, 70 percent of our water is used for agriculture, yet 50 percent of the food produced gets thrown away. Five percent of our energy goes to pump water, but 20 percent of that water streams out holes in leaky pipes. “The examples are endless,” says Williams, “the bottom line is the same: Show me a water problem and I’ll show you an information problem.”
