The Better Life Index is part of the OECD Better Life Initiative, which aims to develop statistics that better capture aspects of life quality. In 2012, proven oil reserves stood at about 15.3 billion barrels and natural gas reserves at 450 billion m3, with roughly 90% of both resources located offshore (ANP, 2013). Conversion losses in hydropower are minimal, which makes it a much more efficient form of energy generation than fossil fuel combustion.
