Challenges to the National Grid, from Net Zero

We continue to be told that wind and solar will be free, when the cost of electricity is already 30% higher than the wholesale price, and wind capacity factors have been reduced by almost 30% relative to those quoted in the original Net Zero case for their use.  Also, the cost of back up capacity must be included when costing Renewables.  

The Royal Society estimates that 100TWh of energy will be needed per annum for that. During his talk, Roger will address these and other challenges.
