A nuclear power plant worker obsessed with counting has set himself an upper limit for electricity consumption that he wants to keep to. But the energy that was supposed to last him for the rest of his life is slowly running out, forcing him to decide on its final use. 3 MWh is a film poem about degrowth and shows what it would look like if humans stopped placing themselves at the centre of nature. An analogue 16mm film footage, damaged by digitally recorded electrical discharges and based on the voice of the protagonist, demonstrates the relationship between man and material reality.
