Companies have been betting on battery-powered planes to reduce the aviation industry's pollution, but electric planes have not yet taken off due to two main problems. First, batteries are not as efficient as gas, weighing planes down and reducing their range. Second, it takes years to certify electric planes for safety and reliability, although companies have started retrofitting old planes to get certified more quickly. However, electric planes designed from scratch, such as the nine-seater plane Alice, could ultimately be more successful than retrofitted planes. Electric planes could potentially revive struggling regional airports and expand the number of destinations. In the future, electric aviation may also include vertical takeoff and landing vehicles (EV tolls), but major investments in battery development will be necessary to make them economically feasible.
