Resources of materials and energy — AQA GCSE Combined Science Synergy

Your focus

1. The example of metal extraction is used to show how the Earth’s natural resources are used to manufacture useful products. A variety of renewable and non-renewable energy resources is needed for these and other aspects of modern life. In order to operate sustainably, scientists and engineers seek to minimise the use of limited resources, cut energy consumption, reduce waste and limit environmental impacts. Scientists also aim to develop ways of disposing of products at the end of their useful life in ways that ensure that materials and stored energy are utilised. Life cycle assessments can be used to compare the overall impact of the production, use and disposal of products.
