Slow burn? The long road to a zero-emissions UK

It is the near future. You wake in a house warmed by a heat pump that extracts energy from deep below the ground and delivers it to your home. You rise and make yourself a cup of tea – from water boiled on a hydrogen-burning kitchen stove. Then you head to work – in a robot-driven electric car directed by central control network to avoid traffic jams. At midday, you pause for lunch: a sandwich made of meat grown in a laboratory.
