The new report by Oxfam claims that even if governments meet their climate and energy commitments for 2020, Europe's annual energy imports bill will soar from £325 billion to more than £400 billion by 2030 because of rising prices.
At the same time the EU's food import bill could rise as climate change hits countries where much of the bloc's food is produced, the report said, leaving Europe's poor struggling to pay for both heating and food.
European countries must work to stop their "dirty energy addiction" and seek alternative fuel sources or the poorest members of society will pay the price, Oxfam have said.
Oxfam's campaigns and policy director Sally Copley said: "Unless Europe acts now to break its addiction to dirty and costly fossil fuels then both Europeans and the world's poorest will pay the price.
"It's in all our interests for Europe to end its reliance on dirty imports and instead develop clean, safe and affordable energy at home."
Oxfam is calling on Europe to agree an energy and climate change package of measures for 2030 that commits to energy savings of 40%, emissions cuts of at least 55% and boosting sustainable renewable energy to 45% of the energy mix.
Europe imports half its energy, predominantly fossil fuels - and Russia is the EU's top supplier for both oil and gas, with European countries paying more than £200 per person to Russian oil and gas giants last year, Oxfam said.
The over-reliance on fossil fuels worsens climate change which in turn threatens agricultural production and pushes up food prices, the charity warned. The world's poorest people are already suffering greater hunger as a result of climate change, it said
The turmoil in Ukraine should be a wake-up call for Europe's looming fuel and food crisis, campaigners have warned.
Ahead of the G7 summit, organised by leaders after they decided to boycott a planned G8 summit in Russia this week, Oxfam said tension with Moscow over the situation in Ukraine highlighted the need for Europe to reassess its energy mix.
One the UK's key underground pipelines has been shut down as police investigate whether tens of thousands of litres of fuel have been extracted from it.
It is understood that detectives are investigating whether the 30,000 litres of fuel was extracted from a pipeline running from the Esso refinery at Fawley.
The Midline pipeline was built in the 1980s and runs underground carrying fuel through Wiltshire to the Midlands, including Birmingham International Airport.
Two men have been arrested in connection with the theft of tens of thousands of litres of fuel which is believed to have been stolen from one of the country's main underground oil pipes.
The large quantity of diesel was discovered in a warehouse in West Wellow, on the Hampshire/Wiltshire border, on Thursday.
Two men, aged 32 and 34, were arrested in Salisbury, Wiltshire, and are being questioned by detectives from Hampshire police
More than two million children are 'growing up cold' in England, according to new figures released today, as a poll suggests that UK parents are sacrificing buying family essentials in order to heat their homes.
The shocking figures from ACE Research for the Energy Bill Revolution show the number of children living in fuel poverty has increased by 460,000 over the past year, a dramatic 26% rise.
The sky high fuel poverty figures are a result of high energy bills, cuts to Government support for the fuel poor and the woeful standards of insulation of Britain's homes.
The shadow transport secretary Mary Creagh has dismissed the Government's plans to cut petrol prices at motorway service stations and a freeze on the cost of the MoT test:
David Cameron’s cost of living crisis has pushed up the price of owning and running a car.
These announcements will be cold comfort for motorists being squeezed on the road and at home.
Prices have gone up faster than wages in 39 of the 40 months while he has been Prime Minister and working people are almost £1,500 a year worse off.
The AA has long campaigned for motorway fuel prices to be displayed at the start of motorways, as they do in France, so that the driver can make an informed choice on where to fill up.
Prices can be 10p per litre more expensive than can be obtained from supermarket pumps or where there is greater local competition for topping up drivers' fuel tanks.
Whilst we understand that Motorway Service Areas have higher running costs, we welcome Government moves for greater transparency in fuel prices.
Justice Secretary Chris Grayling said whiplash cheats, whose bogus compensation claims have helped to force up average motor insurance premiums, will be targeted by new independent medical panels which will ensure only evidence from accredited professionals can be considered.
We are turning the tide on the compensation culture and helping hard-working people by tackling high insurance premiums and other motoring costs.
It's not right that people who cheat the insurance system get away with it while forcing up the price for everyone else - so we are now going after whiplash fraudsters and will keep on driving premiums down.
