Based on the analysis in Without The Hot Air, can we live on (UK) renewables in the UK? Answer: only if the green (renewable generation column) can be made at least as tall as the red (consumption) column, even ignoring issues such as intermittency (eg wind doesn't blow on demand to turn turbines during the TV soap break).
Press the buttons (or enter your own numbers from your own spreadsheet) to find a way to keep the lights on without costing us too much each day or taking too much space!
Look at the bottom of the green stack and you'll see the cost per person per day and how many UKs worth of land area you need to generate as you've specified. There's also a costs table further down for more detail.

As to the 'area' costs computed, note that it may be possible to deploy a given land area for multiple uses, eg solar PV on housing roofspace (and heat-pumps underneath), solar farms under turbines with geothermal extraction from under them. Not all the area 'cost' computed is inland, eg for off-shore wind.
