Energy is considered to be the most important challenge for today and tomorrow as our energy system is mainly based on limited fossil fuels. It is not only scientific aspects that are of interest, but also economic, environmental and social, since many politicians and journalists believe that energy could be the cause of the next world war. Bearing this in mind, it is clear why affordable solutions are desperately needed. An easy read, balancing the pros and cons, this book explains the basic concepts, provides a historical overview and accurately assesses our current energy system, while outlining such alternatives as nuclear fusion and fission, solar energy and other renewables. An excellent source of information and a must–read for chemists, physicists, ecologists, energy–supplying companies, engineers, politicians and journalists.
