Which of the following are possible methods of decreasing the amount of energy required to transport people to and from work?

1. Investing in public transportation: Investing in public transportation such as buses, trains, and subways can help reduce the amount of energy required to transport people to and from work. Public transportation allows multiple people to traveling together in a single vehicle, resulting in energy efficiency and fewer emissions than if people traveled to work alone in their cars. 2. Promoting bike commuting: Promoting bike commuting can also reduce the energy required to transport people to and from work. This can be done by providing dedicated bike lanes and cyclist-friendly infrastructure, as well as encouraging employers to offer incentives for cycling to work. 3. Carpooling: Carpooling is another possible way to reduce the energy used to transport people to and from work. Carpooling allows multiple people to ride in a single car, which is more energy-efficient than if everyone drove alone. 4. Telecommuting: Telecommuting is a way for people to work from home, eliminating or reducing the need to commute to work. This can significantly reduce the amount of energy required to transport people to and from work.
