Solar Energy in cars?

Cars are using solar energy to make them run. There are so many advantages to solar powered cars, such as ninety percent of the energy produced going straight to the car, versus fifteen percent from fossil fueled energy (Solar Energy Cars, para. 11).

Solar powered cars are a new and upcoming idea in the solar energy world. They are a good idea as they will cut down on the amount of carbon dioxide emitted into the air. Being a new idea, and the fact that not many solar powered cars are actually produced, it is more so a concept than a reality. The price of producing a car like this would be very expensive. The car would have to be covered in solar cells which are expensive to make. Another problem is that even though the car is covered in solar cells, it still may not be enough to power the car to the standards of a normal car taking into account highways, road conditions, inclement weather, etc. Solar powered cars are the future of automobiles- there has already been progress made in electric cars. People need to make the small steps toward completely solar-run automobiles.
