Do hereby confirm that the report hereinafter is my own work and no part of it has been copied from anywhere; as a result, the information presented has been
suitably referenced. This report entails an evaluation of the renewable energy capacities in lieu of the existing generation sources and this is part of my assessment for
course B51GK Demand Management & Energy

1. INTRODUCTION
The government of Scotland set ambitious targets of transforming the renewable energy markets and boosting the country’s power efficiency [6, 7, and 15]. This is in line with
the global targets of carbon emissions following the international ratification of the climate change pact in Paris 2016. The fossil fuels have greatly contributed to the global
menace of climate change as levels of carbon emissions due to these archaic sources have resulted into the damaging of the ozone layer; consequently, resulting into
unpredictable climatic patterns and further deterioration of the existing natural forms of life[6] . From the projections, as will be illustrated in the report, it can be noted that
the Scottish government targets to meet the escalating demand of energy by 100% by the year 2020. It will be assumed therefore, that in this report, the set targets are
attainable. However, there is need to conduct a thorough evaluation of the efficiency of the existing energy sources and correlate with the demand and supply situation all
over the country. In a nutshell, the government of Scotland has set a target of 16 GW of power to be generated from the various listed sources; it should be noted that the
renewable energy will greatly be integrated so as to boost the capacity, efficiency and contribute to sustainable levels of energy generation such that there will be zero carbon
footprints[15]. This would actually require great innovation from the stakeholders so as to improve the energy situation in Scotland and consequently a clear road map will be
generated on the exactness of attaining the set target[16]. The aim is to uncover the energy generation performances as at 2017 and use the report to further plan on the
achievements motives.

1. RENEWABLE ENERGY GENERATION POTENTIAL AND EXISTING DEMAND
In this section, we explore the various renewable sources of energy as a solution to bridge the existing gap between demand and supply of electricity in Scotland.
Part 2.1: Closing the Energy Supply Gap using 100% Renewable Energy Sources
Based on an upscale of the current generation mix for renewable technologies (see table 1) and the current typical electricity demand, the amount of energy storage capacity
that Scotland would need to satisfy all its electricity needs [8]with renewable generation is hereby provided:
