Leave vote makes UK's transition to clean energy harder, say experts

Analysts say Brexit will create uncertainty for energy sector, which could hit 20bn investment a year needed to replace ageing, dirty power plants

The UK's challenge to build a clean, secure and affordable energy system has become significantly harder amid the political and economic turmoil following the nation's vote to leave the European Union.

Higher customer bills and delayed or cancelled projects are expected by experts, the most pessimistic of whom warn of the lights going out. The optimists argue that the global rush towards clean energy and strong domestic UK climate change targets can keep the transition to clean, green energy moving forward.
