Community Energy in Ireland (Part 3)

In the final part of his report, Erik-Jan Van Oosten reminds us that technologies aren’t neutral and that their complexity needs to be taken into account when planning for future energy production.

Future energy availability: ‘net energy’ and the Energy Internal Rate of Return

This week we are publishing two articles from Fleeing Vesuvius which focus on energy supply and use. Chris Vernon's paper explains why, although there is a lot of oil still left in the ground, its supply will contract very rapidly indeed and the world may have run out of oil to burn for energy by 2050. Tom Konrad argues that if a standard assessment tool, the internal rate of return, is used to compare the net energy yield of various projects, it shows which to prioritise for the energy transition.
