A Sun to Fill the Energy Gap

Cylon Gonçalves da Silva

The level of energy consumption is escalating at alarming rates in today’s civilization. Over 80% of the energy produced on earth is of fossil origins – which aside from environmental issues will eventually end. How to fill the gap between the energy we need to keep surviving and growing, and the energy we have available?

The author approaches this matter in a very clever and attractive way by comparing the different energy sources that can fill the energy gap. The power of sun radiation is over ten thousand times the energy we are currently consuming. Sources of primary energy for renewable energy sources are wind, hydraulic, thermal solar, photovoltaic, and bio fuels.

The book is a comprehensive and up-to-date overview on energy and its related issues.
