Can renewable energy power the world?

Week 8: Towards a renewable future

Introduction

In the preceding seven weeks of the course, you’ve looked in turn at the principal renewable energy sources and described the individual contributions they might make to the energy needs of the UK, Europe and the world, under various conditions.

In this final week we draw the threads together. We examine a number of future energy scenarios showing how combinations of renewable sources could provide all, or most, of the energy needs of the United Kingdom, of other European countries and the World as a whole, during the first few decades of the 21st century. We start with the UK.

In the preceding seven weeks of the course we’ve looked in turn at the principle renewable energy sources describing their underlying technologies, their economics and their environmental impact. We’ve also looked at the contributions they might make to the energy needs of the UK, Europe and the world under certain conditions.

In this final week we draw our threads together. We examine a number of future energy scenarios showing how combinations of renewable energy sources could provide all or most of the energy needs of the United Kingdom, of other European countries such as Denmark and Germany and of the world as a whole during the first few decades of the 21st century.

This final week also includes a series of six short video interviews with key figures in the renewable energy industry who give their expert opinions on how much energy could be supplied by renewables to the UK, other European countries and the world as a whole.

There is little doubt that the technical, social and political challenges involved in phasing out conventional fuels are formidable. But as you will see it’s hard to avoid the conclusion that renewables are likely to play a greatly increased role in world energy supplies. And if the optimists are correct, given sufficient support from governments, industry and the public renewable energy could power the world.
