As one of the UK’s renewable energy chiefs has pointed out, electric cars won’t tackle climate change if they run off fossil fuels. Matthew Wright, managing director of Dong Energy UK, said that although plug-in cars could cut local air pollution, it would be a “pyrrhic victory” if they increased greenhouse gases from coal and gas power stations. “The fit between renewable energy and electric is a natural [one],” he argued. E.ON, one of the big-six energy suppliers, agrees: its dedicated new electric car tariff is supplied with 100% renewable power. Put simply, the greener the electricity mix, the greener your electric car. Today, around half of power generated in the UK comes from low-carbon sources. Here’s how that breaks down, and how it might look in the future. Nuclear power stations usually provide between a fifth and a quarter of the UK’s power, taking a 23.6% share during April and June. EDF, which is building Britain’s first new nuclear station in decades at Hinkley Point in Somerset, thinks that by 2035, nuclear’s share should grow to around a third of UK power supply. For atomic power to supply a third of the UK’s needs, Hinkley Point C will need to be finished on time, and three more plants of a similar size will need to be built.
