Renewable Energy Resources

The UK has a constantly increasing energy demand; rising population in the UK and, since industrial revolution in 19th century, technological advances have rendered older “fuel-less” technologies obsolete. Where the UK sources its own energy from is becoming increasingly significant as indigenous energy reserves diminish, not to mention the implications of “peak oil” of worldwide resources.

Figure 1 displays the variation of the UK energy supply a period of 16 years. In these years, the use of coal has significantly dropped. Closure of many UK based coal mines and an EU commitment for reduced Green House Gas (GHG) emissions has discouraged UK demand for coal as a primary energy source. Since the total energy demand has continued to increase, replacement energy sources have been required. The largest increase in primary energy source has been from natural gas. Meanwhile the proportion energy from Nuclear power, Oil and other sources of energy have remained relatively constant throughout the 16 years of energy consumption; suggesting that little development exists within these areas. We acknowledge this to be untrue, with the development of wind farms, solar energy and geothermal, but relative to increasing demand the contribution from renewable sources has been extremely difficult with fossil fuels and gas remaining the cheaper fuel to meet the UK energy demands.
