Energy

This technology is very efficient and produces no pollutants. Although this is a very efficient fuel, there are only 13 hydrogen stations in the world because of its cost.
             Some new cars are now equipped with solar panels. On these panels are light sensitive photo-voltaic cells. When light strikes the cells, the electrons are excited and the light energy is able to be converted into electricity. The electricity is then used to charge seven rechargeable batteries, and from there power an electric motor to run the car. Solar cars are much lighter than regular cars. Weighing around 600 pounds a solar powered car can travel the same speeds as regular cars, but five times more efficient. Solar powered cars look a lot different from regular cars. They are built for maximum exposure to the sun and being aerodynamic, so most solar powered cars are in the shape of an airplane wing or a teardrop. Unfortunately, these cars are very expensive to manufacture, for example, the Honda Dream costs almost tem million dollars.
             The average household uses around thirteen kilowatts of electricity a day. In large cities, the demand for electricity can be enormous. Currently, power plants around the world generate electricity in various ways. Nuclear fission, hydropower, solar power, wind power etc., but mostly burning of fossil fuels. With a growing global population, and a growing demand for energy, new and better sources are needed.
             Fission power plants are very efficient, and can produce a lot of power at once, but also produce a lot of radioactive and toxic wastes. Although hydropower, wind, and solar power are very environmentally friendly, many countries do not have the money or resources for them. Fusion is the choice of the future. Fusion power is not yet a reality but we know it is possible. The sun produces massive amounts of energy just by fusing hydrogen atoms together to form helium. Only a small quantity of hydrogen is required in a reactor to produce enough power for an entire city.
