Valuing Energy for Global Needs

A more sustainable future will call on us to make deliberate and informed energy choices. Thus the aim of this text is to provide readers with a foundation to evaluate 21st century energy options as clearly and as objectively as possible. Bringing to light engineering environmental and sustainable development perspectives the authors discuss in layman's terms the value we get from energy systems--both positive and negative. In particular the authors emphasize the need to consider the tremendous benefits that have been received through the use of modern energy systems which have been dominated by the exploitation of nonrenewable fossil and nuclear fuels. They argue that these benefits must be extended to impoverished nations and future energy choices must include a judicious mix of alternative energy sources coupled with best practices and conservation principles eliminating the dirtiest of the fuels.
