Oil and gas dependency in 2035
- America's shale-gas boom is set to reverse the flow of the international
 trade in oil and gas. 
 
- America, until recently the world's biggest 
energy consumer before being overhauled by China, has relied on imports 
for decades. But according to the International Energy Agency, that is 
set to change. 
 
- America is all-but self-sufficient in gas because of the 
abundant flows from shale fields. By 2035 it could become a significant 
gas exporter reckons the IEA. 
 
- Meanwhile the same technology is unlocking
 shale oil, which along with fuel efficiency measures, could slash 
America's dependence on oil imports. 
 
- With all sources of energy taken 
together (including nuclear, renewables, etc) the country could hit net 
self-sufficiency by 2035. 
 
- The rest of the world is set to rely even more
 heavily on imports, with the exception of Japan and South Korea, which 
already import all their oil and gas, and the ASEAN region, which will 
have less of a surplus to export.
