Summary
How can we provide clean, safe, environmentally-sustainable energy supplies for Britain, Europe and the world as a whole during the twenty-first century, despite rising population and increasing affluence? You will study the sustainability problems of our conventional fossil and nuclear fuel use, and how they might be relieved; explore the technological and social possibilities for using energy much more efficiently; and investigate various renewable-energy sources (such as solar, wind and biofuels) that significantly reduce effects on the environment. In the course project, you research and write a sustainable energy proposal for your own home, workplace, or community.
Course content
This course explores the main factors likely to influence the long-term evolution of the world’s energy systems, and the technologies and policies that could be adopted to create more sustainable energy systems during the twenty-first century.
The course is divided into four blocks, three are supported by substantial, highly illustrated textbooks, video programmes on DVD, computer-based exercises and a study guide. The final block is supported by printed text, a DVD and readings to be downloaded from the student course website.
Block One deals with conventional energy systems and their sustainability. It begins by explaining basic energy concepts and describing the magnitudes and patterns of human energy needs at various levels. Then comes an overview of the fossil and nuclear-fuelled energy systems that, together with hydroelectric power and traditional biofuels, supply most of the world’s commercial energy needs. A section on costing describes the basic methods by which the monetary costs of energy are calculated. The concluding sections deal with the sustainability problems associated with both fossil and nuclear fuel use, and ways in which they might be ameliorated by various technological and social developments.
Block Two, on renewable energy, provides a comprehensive overview of the principal renewable energy sources: solar thermal energy; solar photovoltaics; bioenergy; hydroelectricity, tidal and wave power; wind power; and geothermal energy. For each source, the physical and technological principles are explained and the economics, environmental impacts and future prospects are examined.
Block Three covers energy management and conservation. It starts with a sizeable section devoted to energy use in ground transport. This examines the technological and non-technical approaches to reducing its environmental impact. These include possibilities for more fuel-efficient cars, alternative fuels and initiatives such as encouraging car-sharing and increased use of public transport. The block continues with a section on saving energy in buildings, looking at the technological possibilities; better insulation, improved heating efficiency and ways of reducing electricity demand and the UK national potential. It also looks at the problems of assessing energy savings. These topics are illustrated with a video on energy use in the buildings of three UK hospitals. It concludes with a discussion of the evolution of national energy efficiency and conservation policies and examining the conflicts and compromises involved in integrating them with other national policies.
Block Four deals with the longer-term prospects for sustainable energy. It examines how patterns of energy use have changed in the past and are likely to change again in future, on both national and world scales. It discusses how appropriate balances might be struck between the different approaches to improving energy sustainability that have been described in the three earlier blocks. This block concludes by comparing and contrasting long-term energy scenarios, national and worldwide, that have been developed by governmental and non-governmental bodies. These bring in a wide variety of assumptions about population and economic growth and the potential for energy conservation or efficiency improvement, and different combinations of carbon-based and carbon-free energy sources.
Associated with the blocks are computer-based exercises designed to develop your understanding of basic physical, economic and environmental concepts. Computer conferencing is strongly encouraged, so that you can take part in online discussions and study groups. The course website gives easy access to additional resources. The video programmes associated with each block include case studies, interviews and animations illustrating sustainable energy projects in the UK and other countries, to broaden your understanding of the systems, processes and people involved. The last part of the course consists of a project in which you investigate and report on the feasibility of a proposed sustainable energy scheme.
By the end of the course you should be able to:
- understand the physical and technological principles of energy supply systems based on fossil, nuclear and renewable sources, and of efficient energy use in buildings, industry and transport
- recognise the main factors that determine the economic viability of energy generation, energy conservation and energy efficiency improvement measures
- discuss the sustainability problems associated with energy use and how they might be resolved by technological and social measures
- perform simple energy-related calculations
- undertake an elementary economic analysis of an energy project, taking into account the effect of such factors as discount rates and project lifetimes
- manipulate computer models of energy systems to determine the likely effect of varying input parameters on energy output or economic viability
- develop your own spreadsheet-based model of an energy system.
As part of your project you will have experience of writing a detailed feasibility study of an energy project, including an assessment of its technological, economic and environmental aspects.
Entry
This is a Level 2 course and it has been devised to suit students from a wide range of backgrounds. Its beginning is designed to bring everyone to the same level of understanding, although you will have a slightly heavier workload in the first few weeks if the ideas are entirely new to you. If you have not studied with The Open University before, we advise you to start with a course at Level 1. If you have not studied maths recently, we suggest you start with one of our 10-point courses, either Starting with maths (Y162) or Science starts here (S154).
If you have any doubt about the suitability of the course, please contact our Student Registration & Enquiry Service.

Assessment
The assessment details for this course can be found in the facts box above.
You can choose whether to submit your tutor-marked assignments (TMAs) on paper or online through the eTMA system. You may want to use the eTMA system for some of your assignments but submit on paper for others. This is entirely your choice.
One of the TMAs is a double-weighted project. Assessment is an essential part of the teaching, so you are expected to complete it all. But if you unavoidably miss or do badly in an assignment, some courses allow you a ‘substitution score’. In T206 this rule can apply to the second, third, fourth or fifth assignment only. You will be given more detailed information when you begin the course.
