"The Energy Report - 100% Renewable Energy by 2050", February 2011
Scenario by WWF and Ecofys, showing that a transition is not only possible but also cost-effective, providing energy that is affordable for all and producing it in ways that can be sustained by the global economy and the planet. The 1st part seeks to generate a discussion around the comprehensively researched scenario that is presented in the 2nd part, conducted by project partner consultancy Ecofys.

"Energy [R]evolution: A Sustainable World Energy Outlook", 2010
Scenario by Greenpeace and EREC provides a detailed practical blueprint for cutting carbon emissions while achieving economic growth by replacing fossil fuels with renewable energy and energy efficiency.
Global CO2 emissions under the Energy [R]evolution scenario would peak in 2015 and drop afterwards. Compared with 1990 CO2 emissions will be more than 80% lower by 2050 if the energy supply is based almost entirely on renewable energies. By 2050 around 95% of electricity could be produced by renewable energy.

Two scenarios are outlines: The first one “Scramble is a quite pessimistic one and in the blueprint scenario, global CO2 emissions would be capped by 2020 and subsequently begin to decline to 2000 levels by 2050.
