The culprit is the federal government’s obsession with energy efficiency. Efficiency standards for washing machines aren’t as well-known as those for light bulbs, which will effectively prohibit 100-watt incandescent bulbs next year. Nor are they the butt of jokes as low-flow toilets are. But in their quiet destruction of a highly affordable, perfectly satisfactory appliance, washer standards demonstrate the harmfulness of the ever-growing body of efficiency mandates.

The federal government first issued energy standards for washers in the early 1990s. When the Department of Energy ratcheted them up a decade later, it was the beginning of the end for top-loaders. Their costlier and harder-to-use rivals—front-loading washing machines—were poised to dominate.

Front-loaders meet federal standards more easily than top-loaders. Because they don’t fully immerse their laundry loads, they use less hot water and therefore less energy. But, as Americans are increasingly learning, front-loaders are expensive, often have mold problems, and don’t let you toss in a wayward sock after they’ve started.
