Britain's oil, coal and gas reserves will run dry in a little over five years, according to a report into energy resources.
A number of European countries, including France, Italy and the UK are facing critical shortages of fossil fuels as the 2020s begin, the Global Sustainability Institute at Anglia Ruskin University.
Using the most recent data on known reserves and current consumption, researchers found the UK has 5.2 years of oil, 4.5 years of coal and three years of gas remaining.
Professor Victor Anderson, also from the institute, said: "Coal, oil and gas resources in Europe are running down and we need alternatives.
"The UK urgently needs to be part of a Europe-wide drive to expand renewable energy sources such as wave, wind, tidal, and solar power."
