Showing changes from revision #0 to #1: Added | Removed | Changed

Six reports cover the Zero carbon Britain 2030 Carbon model, Power down, Renewable energy supply, Hourly energy model, Land use, Food and diets model.

## Renewable energy supply

### Questions

A calculation: 530TWh/y = $530 \times 10^9$ kWh/y. Assuming a population of 60 million, this corresponds to

$\frac{530 \times 10^9}{365 \times 6 \times 10^7} = 24 kWh/day$

per person. This can be compared to MacKay’s estimates of 16 kWh/day for shallow offshore wind plus 32 kWh/day for deep offshore wind.

• 27 TWh a year of carbon-neutral gas is produced and used as backup, producing about 14 TWh/y of electricity. Gas turbines with about 400 TWh/y maximum capacity are needed for this. That seems like a lot of spare capacity: is this a big problem?

## Hourly energy model

The Hourly Energy Model Methodology is used for assessing this plan.
