"Conclusion Each country demands differ and this makes certain types of energy sources suitable and equally some sources not appropriate. China and UK is a perfect example of this as one country wants high productivity levels where as the UK want more sustainable, cheap and eco-friendly options. Each type of multi energy sourcing has its advantages and disadvantages and these need to be evaluated. Each country will have different opinions upon the suitability of different energy sources depending upon what they expect and want. However, every country needs to be prepared for the time when oil supplies begin to run out and there isn't a definite option which is right or wrong. Everyone will have their own opinions and only time will tell who was right."
