They could all ride the bus to school. They could all choose to ride in cars that use more petroleum.

The most effective way to reduce the amount of energy used by Mrs. Cash's students would be for all of them to ride the bus to school. By consolidating the transportation of the students onto a single vehicle, the overall energy consumption would be significantly reduced compared to having each student travel in their own car or having their parents take longer routes. Additionally, using public transportation like buses is usually more energy-efficient than individual cars.
