Dr. Derek Abbott: How do we supply the world's energy needs?
Future energy supply is a major global problem. Although no one knows exactly when oil production will cease, its days are undoubtedly numbered and its environmental shortcomings well recognized. Clearly, however, any alternatives that involve extracting resources from the earth will be similarly unsustainable, at best only temporarily deferring the problem. So where does the answer lie?
In this exciting presentation, Derrick Abbott of the University of Adelaide, Australia, expands our vision to consider energy supply on a massive scale - collaboration between electrical engineers, economists, and chemical engineers could potentially provide solutions to power the entire world. We take a fresh look at the major non-renewable and renewable energy sources and examine their long-term viability, scalability, and the sustainability of the resources that they use. We achieve this by calculating what would happen if each energy source was a single supply of power for the world. From this perspective, we find a dominant solution emerges for providing the world's energy needs.
