The UK Climate Change Act 2008 has set 80% GHG emissions reduction target by 2050, relative to 1990 national GHG emissions. In this essay, DACC 2050 calculator has been used to devise a whole system scenario to assess the actions needed and possible energy mix needed to achieve 80% target by 2050. It has been concluded that for energy security, cost-effectiveness and achievement of 20250 target, wind power and nuclear power will have to play the key role.
In addition to that demand side management, through electrification of heat and transport, and energy efficiency will have to play a significant role. However, technological advancement in CCS, improvement in nuclear power flexibility in operation and geo-sequestration will influence 2050 target achievement.
Demand side management and demand reduction is very important in decarbonization of energy sector. One third of GHG reductions since 1990 are due to change in electricity mix, while two third are due to demand shift and energy efficiency. So, demand side carries considerable potential of GHG reductions.

Excerpt from the Book
COMBINATION OF NUCLEAR AND WIND POWER TO MEETING THE UK’S 2050 DECARBONIZATION TARGET
UK has committed 80% reduction in its Green House Gases (GHG) emission by 2050 relative to emissions in 1990 as per the Climate Change Act 2008 (UKParliament, 2008). This policy proposal, with proposed actions in energy supply side and demand side, has goal of achieving 2050 target ensuring energy security, affordability and stability of energy supply system. We use modelling through DECC 2050 Calculator to suggest measures in all sectors within parameters and constraints set by the tool. In this proposal, our initial goal is to decarbonize electricity sector and shifting heating and transport sectors’ energy demand to electrical energy through electrification of these sectors. Electrification of heating and transport and decarbonization of electricity through renewables, Nuclear and Carbon-Capture-and-Storage(CCS) is key to achieve 2050 targets (Pollitt, 2019)(Jamasb et al., 2011).
Energy security is “the uninterrupted availability of energy sources at an affordable price” (IEA, 2018). Uranium for nuclear power plant is 100% imported by UK while inclusion of CCS supported imported fossil fuels’ power plants aggravate energy security scenario. In this pathway, primary energy import is around 64% (Table ), which means UK energy supply is prone to risks of disruption of sources, due to fluctuations in market prices and regional turmoil. Hence, we have selected a scenario with around 500TWh of electrical energy from wind power into the energy system, followed by Nuclear Power and CCS based power to handle constant load and varying load respectively.
