Can renewable energy sources power the world?

We ask the question ‘Can renewable energy sources power the world?’ as a response to the growing awareness that increased use of renewable energy technologies is making a major contribution to global efforts to limit anthropogenic climate change. The course begins by examining the environmental concerns that have caused a rise in interest in renewable energy, introducing the main sources and technologies, and describing global efforts to increase the share of renewables. The course then looks at each of the principal renewable energy technologies and the contributions they might make to global energy demand. Finally, several future energy scenarios are analysed to show how combinations of renewable energy sources and technologies could provide a major share of global energy needs.

Microbes – friend or foe?

Microbes often get a bad name. Whilst some of them do cause disease, others play vital roles in recycling nutrients in the soil to enable plants to grow, and in breaking down human waste. Without microbes, we would have no beer, no yoghurt, no coffee. That's quite impressive for something too small to see. This free course, Microbes friend or foe? sheds some light on them.
