Outsized pollution and noise from devices like gas-powered leaf blowers are driving the efforts. The gas-to-electric transition at the neoclassical landmark, which has stood for more than two centuries in Georgetown, came ahead of a ban on the use of gas-powered leaf blowers that went into effect in the nation's capital last year. California next year will ban the sale of new gas-powered leaf blowers and lawn mowers, among other equipment, though the state will still allow existing devices to be used. That's in part because about 30% of the oil-and-gas mix that powers so-called two-stroke engines, which often run tools like leaf blowers and string trimmers, isn't burned. Whalley was already a proponent of ditching the gas-powered tools because she'd done so at her own home.
