The report, Energy Revolution: A Sustainable World Energy Outlook, provides a blueprint for how to cut global C02 by almost 50% in the next 43 years.
It emphasises the importance of providing a secure, affordable energy supply while maintaining steady world wide economic development, particularly taking into account rapid growth areas such as China, India and Africa.
The report concludes that renewable energies have the potential to deliver almost 70% of global electricity supply and 65% of global heat supply by the middle of the century.
Greenpeace International energy spokesman Sven Teske said the world was crying out for a way to provide the power needed without fuelling climate change.
“We have shown that the world can have a safe, robust renewable energy, that we can achieve the efficiencies needed and we can do all this while enjoying global economic growth and phasing out damaging sources such as coal and nuclear,” he said.
“Renewable energies are competitive, if governments phase out subsides for fossil and nuclear fuels and introduce the polluter-pays principal.”
However, the outlook report also says there is a narrow window of opportunity for making the key decisions in energy infrastructure, which will have to be made by governments, investment institutions and utility companies.
Many of the existing power plants in OECD countries will come to the end of their technical life and need to be replaced within the next decade, while developing countries such as China, India and Brazil are rapidly building up new energy infrastructure.
