Sweden wants to become the first fossil fuel-free country in the world - how will it work?
The Prime Minister of Sweden, Stefan Löfven, has announced that his country will work towards becoming "one of the first fossil fuel-free welfare states in the world," in a speech to the UN General Assembly.
The Nordic countries already lead the world in renewable energy, with Sweden generating around two-thirds of its electricity through renewable sources.
On one unusually windy day this July, Denmark produced 140 per cent of its electricity needs through wind power alone, exporting the rest of the energy to its neighbours, Germany, Sweden and Norway (one of the biggest oil producers in the world).
And almost 100 per cent of Iceland's electricity comes from renewable sources, due to its investment in hydropower and geothermal energy production.

Biodiversity loss, fertilizer use, climate change and land use have all exceeded Earth-System limits
Biodiversity loss, fertilizer use, climate change and land use have all exceeded Earth-System limits
Human activity over the past century and a half has pushed the Earth into critical mode, say scientists. New research published in Science finds four out of nine 'planetary boundaries' have now been crossed. Biodiversity loss, fertiliser use, climate change and land use have all exceeded the point at which the risk of sliding into a "much less hospitable" world becomes high.
Passing any one of the nine critical boundaries risks disrupting the complex and delicate interactions that exist on Earth between the land, ocean, atmosphere, ice sheets and people, says the team of 18 researchers.
