"The World Energy Scenarios: Composing Energy Futures to 2050", World Energy Council (WEC), October 2013
The WEC World Energy Scenario is a result of a three-year study conducted by over 60 experts from nearly 30 countries, with modelling provided by the Paul Scherrer Institute. The report assesses two contrasting policy scenarios, the more consumer driven Jazz scenario and the more voter-driven Symphony scenario with a key differentiator being the ability of countries to pass through the Doha Climate Gateway.

"The Energy Report - 100% Renewable Energy by 2050", WWF & Ecofys, 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", Greenpeace & EREC, 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.
