Energy Cliff
One problem the world faces is the following
The world runs at 100 million barrels of oil a day. This is what the world consumes. This number has grown 1 million barrels a year for the last 30 years.
When the world found oil in Oklahoma 140 years ago the oil had enough force to explode higher. At that time the EROI was 1 to 100. They spent 1 barrel to collect 100.
fast forward to today and the Shale oil has a EROI of 1 to 15, they have to inject water & sand, make explosions etc...
the world has depleted the easy energy , the cheap energy. Now we need to find oil in very difficult places and very expensive.
Life is going to more difficult, if energy is expensive everything is going to be expensive. The only competitive energy is nuclear but as we know Greenpeace & Greta destroyed the image of Nuclear.
Renewables have an EROI of 1 to 16 without taking account with storage costs ( Batteries )
Below you can see two bar graphs one from Forbes magazine (2015) and one from Charles A. S. Hall (born 1943) is an American systems ecologist and ESF Foundation Distinguished Professor at State University of New York in the College of Environmental Science & Forestry.
we need to use less , I don't see a way out.
as you can see below the jury is out , some people claim nuclear is the cheapest with the best EROI and in the second graph its not the case. When I see poor countries building nuclear and not renewables I know what is cheap.
