with reference to 2 contrasting countries describe and explain differences in the energy mix

Energy sources can be divided into two catogories. One is the non-renewable sources, such as fossil fuels, the most commonly used in the globe. The other one is renewable sources including HEP, wind, solar and wave as well as many other forms. As we all know that the fossil fuels are finite resources, meaning that they will eventually run out. Also, the share of renewable enegy production is very low, which means this might not allow the demand to shift from fossil fuels that we currently rely on to renewable sources. This is currently becoming more and more concerning because not only has the demand risen dramatically due to population growth and aspiration of living in higher standards, but also that fact that global supply of oil, one of the most important energy sources may have reached its peak.

Also, according to the BP reserves-to production ratio, the reseves will only last for another 40years. Many countries often struggle with securing energy sources needed for electricity generation as well as the increasing domestic demand and economical growth. It is clear that as a country becomes more developed, the greater amount of energy needed. The reasons behind these are the fact that they are producing more products from industry manufacturing and argriculture. There are other factors concerning the demands of a growing service sector, increased freight and general business transportation, increasing car ownership and expansion of power networks to isolated area. Therefore, this adds on to pressure of getting the right energy mix for a country. Energy mix is the relative contribution of different energy sources to a country’s energy production/consumption. By doing so, the low import dependencies will allow the supply of energy can be secured which is beneficial to the economical growth.

The energy pattern in the UK

This graph shows the Uk’s electricity production by source from 1980 to 2012. The thermal type clearly dominates all sources, accounted for 225 TWh in 1980 and reached its peak in 2008 at around 290 TWh, followed by a drop in 2009 back down to 260TWh. The second largest production, nuclear power gradually increased from 1980 to 1997, almost reaching 100 TWh, then followed by a constant decline and a obvious drop at 2008. Whereas the renewable and HEP are the least production for electricity, ranging from 0 to 5 TWh between 1980 to 2000. Since then, the HEP remained static; however, there is a obvious growth in the renewable type, up to 25 TWh in 2010.

The reasons

The thermal form is dominating the UK’s production because they are the most abundant, accessible resources of energy despite the fact that they are finite. The consumption of course has increased because more electric devices are used and the growth of population means more energy will be needed. There was a drop in the consumption in 2009 mainly because the world economic recession; however bounced back quickly in one year. The production of nuclear power was growing because it only needs comparatively small amount of sources and it produces a relatively high output. The growth, however, ...
