Week 1: Introducing renewable energy


In this first week you will look at the environmental concerns that have caused the rise in interest in renewable energy. You will also explore the wide variety of renewable energy sources, along with some energy concepts and definitions to help you understand the subject.

You will investigate the Sun, which powers most of the renewable energy sources, then move on to discuss energy supply and demand, in the world and the UK, and then look briefly at the problem of climate change.

Current European and UK targets for increasing the share of renewables in coming decades will also be covered.
