new chapter 3.4 : EROI versus CO2 for energy conversion routes

While we are part of a energy transition globally, many calculations are made based on costs, in cts/kWh, and wind and solar now seem to become very cheap. But its not about costs. That’s artificial, its about real and absolute CO2 levels, and energy efficiency. So I found data for EROI ( energy return on investment), and for CO2 emissions/kWh. And I put them together: which one scores best in both categories? Only 3…

Germany: a greenhouse gas-neutral Country

In a society to function sustainable, it is assumed that the yearly CO2 budget per capita is 1 ton. ( Where its is now around 10 ton CO2-eq per capita year in countries like Germany and the Netherlands). A major challenge. In this report by the German ministry for the environment, this scenario is explored:

To make the consequence of (remaining ) CO2 budgets imaginable, the introduction of a basic calculation can show the scale of the transition required, for a industrialized country.
The Netherlands has 17 million inhabitants, if the CO2 budget is equally divided globally , The Netherlands can claim 17million out of 7 billion = 0,0025 part the budget (B), or 0,5 Gt CO2 under the 1,5 degree scenario (B1,5), and 2,2 Gt under the B2 degree scenario.. ( Which is optimistic, since global population is growing and the trend is for increasing demand , further reducing local and per capita budgets. ) If we assume that for the reform of society the attribution per sector remains the same, then 40% can be attributed for the building and housing sector, operations and investments , or B1,5 = 0,2 Gt CO2 and B2=0,8 Gton (- remaining to be emitted from the building and housing sector).
