EXECUTIVE SUMMARY

Energy is a key element of our economy and essential source of our living. However, the main sources of energy we currently use are the fossil fuels which are non-renewable and release greenhouse gases (i.e. carbon dioxide) into the atmosphere. According to the Intergovernmental Panel on Climate Change (IPCC), 2007, rising carbon dioxide (CO2) levels are the primary cause of global warming since 1950, and are expected to rise due to ongoing burning of fossil fuels and land-use change.

UK currently contributes about 2 per cent to global emissions, which, according to the IPCC, were estimated to be 38 billion tonnes carbon dioxide in 2004. UK energy industries are the main contributors to UK greenhouse gas emissions, CO2 accounted for about 85 per cent of the UK's greenhouse gas emissions in 2006. In order to reduce emissions, 2003 UK Energy White Paper sets out an objective to cut carbon dioxide emissions by 60% and create a low carbon economy by 2050. One way of achieving those targets would be by generating our energy from sources that produce very low or zero levels of greenhouse gases such as renewable energy sources. . Renewable sources of energy release no greenhouse gases in generating electricity, and carbon-neutral over their life cycle. The UK has a strong potential for renewable energy resource, particularly in wind and wave power. Because of this, renewable energy will have a key role in improving the climate change situation, and the UK policy on renewables will propose the initiative for development of a more efficient approach to energy use.

This dissertation will examine the factors driving the development of renewable energy market in the UK, and the government's role in driving CO2 reductions. The analysis will be divided into two parts; first part would consider the prospects and contribution of renewables to the UK economy, second part would specifically concentrate on evaluation of whether the policies and targets set by government are achievable, and conclusion will summarize the future prospects and recommendations for the renewable energy market in the UK.

CHAPTER 1: INTRODUCTION

'A sustainable energy future is possible, but only if we act urgently and decisively to promote, develop and deploy a full mix of energy technologies... We have the means, now we need the will…”

Claude Mandil, International Energy Agency (IEA)

In 21st century, there has been a significant increase in energy demand due to the factors such as population growth and our modern lifestyles, according to the International Energy Agency (IEA) today 86.5 % of total worldwide energy consumption is generated from fossil fuels such as natural gas, oil and coal; which are said to be non-renewable, and are the main cause for the increase in green house gases and carbon dioxide emitted into the atmosphere. As the world's fossil fuels continue to diminish at an alarming rate, and the global energy demand forecasted to increase by 60% over the next 25 years (G8 Summit, 2005) an alternative, clean and sustainable new forms of energy must be developed that are economically cost effective, environmentally friendly, and easily harnessed. The development of renewable energy sources as a solution to these problems has gained a significant amount of support evident within international agreements, national government policies, environmental group and public support. The term has no definitive definition but is generally agreed to be sources of fuel that are;

RENEWABLE ENERGY IN THE UK

Renewable Energy can be defined as clean energy generated from the sources replenished rapidly by natural processes, such as wind, solar, geothermal, wave, hydro, and biomass which also produce low or non greenhouse emissions. , and relies on the According to the Article 2 of EC Directive 2001/77 EC, the term “renewable energy source”

Economics of Renewable Energy - The pricing mechanism and energy. Economics of extracting energy. Economic instruments for the environment: pollution taxes, tradable pollution permits, and environmental valuation. Economic incentives or renewables ROCs. The cost-efficiency of renewable technologies.
