To deal with the air pollution caused by vehicles in cities is a challenging job．My suggestion is to produce vehicles powered by solar energy． Compared with mineral fuels such as gasoline，solar energy is inexhaustible in supply．The growth of cities and increase of vehicles call for more supply of energy，but there is a limit to the reserve of mineral fuels．So solar energy with its endless supply is one of our solutions to energy crisis．The second advantage of solar energy is its cleanliness．Traditional vehicles operating on gasoline give off exhaust，causing damage to human health and polluting the air．From the perspective of environmental protection，solar energy is a much better choice．After the new technology becomes economically feasible，the sky over cities will be brighter．and the air will no longer be a threat to our health． Because of the two benefits of using solar energy as a new fuel，we should spend more money on the research which can make our dream come true．
