Energy Secretary Ed Miliband has called for countries to cooperate to reduce the risk to global energy supplies.
He was speaking at the opening of a two day summit on energy security in London, which is being attended by delegates from more than 50 governments, including the US and the EU.
Miliband also warned of the risks from energy being "weaponised", seen as a reference to the impact of the Russian invasion of Ukraine on gas prices.
Delegates will be discussing how to reduce the mounting risks to energy arising from the wars in Europe and the Middle East, the ongoing trade war between the US and China, extreme weather, attacks on undersea cable and cyber warfare.
