As an energy crisis and cost of living crisis collide, the Lincolnshire lorry mechanic and motorcycle racer investigates the past, present and future of British power stations to work out how the country makes its most valuable commodity of all - electricity. This first episode begins with Guy testing every piece of equipment in his workshop to find out which items use the most electricity. Horrified by what he's now having to pay for power, he tries to work out the reasons behind his big bills, and visits his local power station at Drax - which also happens to be the country's biggest.
