Design an Energy Efficient Car You have started a company to design cars that do not waste energy, are inexpensive, and non-polluting. Your car may use alternate energy sources and new technologies to increase efficiency. The new car you plan to build must be able to travel at least five hundred miles before you have to add fuel and be able to carry a family of six people. Aerodynamics, car weight, and design all play an important role in your final product.
Natural gas is formed from plant matter that has decayed over millions of years.
Since the formation of natural gas occurs over such a long period of time, it is a limited natural resource of energy. However, we use natural gas to fuel our cars, and car engines are not very energy-efficient. Some of the energy from gasoline is wasted as heat. You can observe the wasted energy by feeling how hot the hood of your car gets after it has been running. Since some researchers think that our natural reserves of gasoline will only last for another sixty years, using gasoline to fuel our cars is a waste of this precious fuel supply.
