Abstract
This chapter examines growing concerns over global energy security, as continuing demand for fossil fuels by industrialized economies is matched by increasing uncertainties over future energy reserves. With a particular focus on the politics of oil (which remains the key global energy source), it will assess the ways in which increasing energy insecurity amongst the world’s major powers will impact upon international security more broadly, and will discuss different understandings of the likelihood of future ‘resource wars’ and a new era of geo-political rivalry. The chapter will also examine the impact that the search for energy security by states in the Global North has upon the human security of communities in the oil-rich Global South. Finally, the chapter will examine the central role played by the USA in underpinning global energy security in the post-war era, and the impact that this has had for oil-rich regions.
