Traditionally we have relied heavily upon non-renewable energy resources, however we have now reached a tipping point globally where the environment cannot sustain such impact, nor do we have the resources to continue this. This program clearly shows the environmental impacts of both renewable and non-renewable energy sources. It guides us through numerous renewable energy sources, how the energy is collected and the pros and cons of renewable energy. The program also explores what is happening around the globe with the introduction of wind farms, wave parks and solar farms. This is an up-to-date look at a vital issue.
