Abstract
Energy affects all aspects of modern life. Energy sources will play an important role in the world’s future. Because of the exponential growth of the world population, demand for energy is increasing at an exponential rate. Current examples of these priorities include: reducing greenhouse gas emissions, improving the energy efficiency of our homes, offices and industries, energy marketing, energy cost, energy management, energy conservation, energy security, finding practical and affordable alternate sources of energy, developing cleaner and more efficient transportation vehicles and systems, energy policy, energy strategy and alternative energy usage. The world is presently confronted with twin crises of fossil fuel depletion and environmental degradation.
