Focusing on the impact of Brexit on the United Kingdom (UK) energy sector through an examination of Energy Law, this short form title examines how the Brexit will affect the UK’s energy legislation and what will be the consequences of this. It then considers the core areas of market dynamics and access, supply, finance, specific energy source issues and relationships with neighbouring states. The culmination of a Brexit policy will result in a need for an Independent UK to make decisions on its energy policy and law sooner rather than later, and thus the text will also examine different scenarios that may arise in the future.
