World energy consumption
World energy consumption refers to the total energy used by all of human civilization. Typically measured per year, it involves all energy harnessed from every energy source applied towards humanity's endeavors across every single industrial and technological sector, across every country. Being the power source metric of civilization, World Energy Consumption has deep implications for humanity's social-economic-political sphere.Institutions such as the International Energy Agency (IEA), the U.S. Energy Information Administration (EIA), and the European Environment Agency record and publish energy data periodically. Improved data and understanding of World Energy Consumption may reveal systemic trends and patterns, which could help frame current energy issues and encourage movement towards collectively useful solutions.In 2012, the IEA estimated that the world energy consumption was 155,505 terawatt-hour (TWh), or 5.598 × 1020 joules. This works out to 17.7 TW, or a bit less than the estimated 20 TW produced by radioactive decay on earth. From 2000–2012 coal was the source of energy with the largest growth. The use of oil and natural gas also had considerable growth, followed by hydro power and renewable energy. Renewable energy grew at a rate faster than any other time in history during this period, which can possibly be explained by an increase in international investment in renewable energy. The demand for nuclear energy decreased, possibly due to the accidents at Chernobyl and Three Mile Island.In 2011, expenditures on energy totaled over 6 trillion USD, or about 10% of the world gross domestic product (GDP). Europe spends close to one quarter of the world energy expenditures, Americans close to 20%, and Japan 6%.
