Over the last decade, the biggest change in energy was how and where hydrocarbons were removed from the earth. The United States led this change. However, a different kind of energy revolution will take place between now and 2025. While the last decade was about the energy buried in the earth and how to get it out, the next decade will be about how the energy already removed from the earth is moved across it. An energy-transit revolution has begun. The consequences of this next energy revolution will be geopolitical and important. --John Richard Cookson, The National Interest, 4 September 2015
