Biofuels in the 2050 calculator


I've been playing about with DECC's 2050 calculator and I wondered if BH readers (if any of you are still popping by) to take a look at something.
I'm interested in how it handles bioenergy. Here's how the relevant help screen describes the process.
In 2007, the UK used 4000 km2 of land to grow energy crops, which is less than 2% of the country. For comparison, 174 000 km2 of land was used for arable crops, livestock, and fallow land. The 2050 Calculator contains two options relating to agricultural biomass and land use: land use management (described here) and livestock management (described on another page).
In his book, Mackay uses a value of 244,000 km2 for the area of the UK, so "less than 2%" is correct.
