The world could eliminate fossil fuel use by 2090, saving $18 trillion in future fuel costs and creating a $360 billion industry that provides half of the world's electricity, the European Renewable Energy Council (EREC) and environmental group Greenpeace said on Monday.
The 210-page study [pdf] is one of few reports – even by lobby groups – to look in detail at how energy use would have to be overhauled to meet the toughest scenarios for curbing greenhouse gases outlined by the Intergovernmental Panel on Climate Change.
Solar power, biomass such as biofuels or wood, geothermal energy and wind could be the leading energies by 2090 in a shift from fossil fuels blamed by the IPCC for stoking global warming.
The report urged measures such as a phase-out of subsidies for fossil fuels and nuclear energy, "cap and trade" systems for greenhouse gas emissions, legally binging targets for renewable energies and tough efficiency standards for buildings and vehicles.
