본문내용

There are numerous types of fuel, which could substitute fossil fuels for future transportation. The amount of fossil fuels such as oil and gas is obviously limited. Therefore, humans should find other sources of energy to replace the existing fossil fuels and consider the environment. Several types of fuel for future transportation are discussed. The first type is solar energy, which is limitless, powerful, and environmentally sound. For these reasons, it has been used for many years. However, because of some technological deficiencies, people can only use solar energy in part. Moreover, it does not work when the weather is overcast, and the equipment is still too expensive.
