"There’s a meme floating around on various social media platforms that an
electric tractor would find it virtually impossible to do, say, 6,000 ha for
seeding.
The assumption is that the 30,000 litres of diesel needed for 35 days of
seeding is roughly equivalent to 320 megawatt hours fuel – and they contend
that an electric tractor couldn’t do this.
Because why? Well they say these numbers are impossibly big for an electric
tractor to work.
But you need to start the calculation at the right point:
First of all, an efficient electric tractor only needs around 1/3 of that
diesel – just 110 MWh over 35 days – if you eliminate the thermal
inefficiencies of internal combustion engines.
An electric tractor, therefore, will need to consume around 3.1 MWh/day, and
that can be met by around 1 ha of solar and about 2.5 MWh of batteries"
