methods. The gasoline engine in a conventional car is less than 20% efficient in converting the chemical energy in gasoline into power that moves the vehicle‚ under normal driving conditions. ("Hydrogen Fuel Cells.") Hydrogen fuel cell vehicles use electric motors and are much more energy efficient. They use 40-60 percent of the fuel’s energy. This would correspond to more than a 50% reduction in fuel consumption when compared to a conventional vehicle with an internal combustion engine. Fuel cells are

from the combustion of sulphur-containing fossil fuels such as coal for domestic and industrial purpose.[i] Industrial development and the use of fossil fuels have affected the world climate adversely. In Nigeria epileptic power supply has brought about the use of diesel and petrol powered generators virtually in all homes 2. The transport induced environmental pollution in Nigeria‚ is further compounded by recent influx of motorcycles and tricycles‚ most of which have 2-stroke engines. Equally

is to know the feasibility of the hybrid car against the petrol car. The procedure adopted for the comparative analysis is to do life cycle costing of both the engines by considering the cost‚ benefits‚ maintenance and repairs for both the engines. The weight scoring model was also developed to analyze the feasibility of both the engines on the grounds of terms like safety‚ comfort‚ emissions and incentives. After completing the comparative analysis the life cycle costing model and the weight scoring

Fossil fuels are unequally distributed throughout the earth consentarting in those areas where carbon-based life forms used to thrive. Since the invention of internal combustion engine‚ petroleum and other fossil fuels have become dominant all over the globe. Thus‚ countries in possession of them have gained economic advantage and polical control over the rest of the world forced to buy petrol at the named price. Countries

Electric cars can produce much lower emissions than burning fuel in mobile engines. The differences between an electric car and a normal one are that they reflect the different design and utility targets for the vehicles.
