This graph from a Gas and Oil Industry report shows world oil production peaking in about 2004.
There are no new energy sources with as much power as fossil fuels (coal, oil and natural gas).
This is a computer model of the economy showing economic consumers using our two energy sources:
This could be a view of the distant lower-energy future.
20 million joules of direct and indirect sunlight are used to produce each part of this energy chain. That is the solar emergy of each component.
Therefore, the emergy in 100 joules of electricity is 20 million solar emergy joules (sej).
This cartoon shows that people have the concept of two values:the energy in a person now and the energy it has taken to make him, his emergy.
In an even dollar trade the USA can buy 4.8 E12 sej from Brazil; whereas Brazil can only buy 1.2 E12 sej from the USA.
A loan from the USA to Brazil at 10% interest is an advantage to the USA, in emergy units, of 5.3 to 1.2.
This is the way world trade seems today.
