As we want to get rid of fossil fuels, we will at least have to develop everything now without fossil fuels. And in any case the operational energy. In the case of new buildings this leads to “0-energy buildings”, which… Continue Reading →

EROI versus CO2/kWh: energy supply under a 800 Gt scenario

23 juli 2017admin
eroi-co2-new

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. Which is positive, but cost unfortunately do not say anything about he… Continue Reading →
