The push to keep fossil fuels in the ground is coupled by a need to transition to an energy system based on renewables like solar and wind. With dropping technology costs, increased efficiency and growing public pressure, a global transition to 100% renewables seems more possible than ever before.

“Energy transition is no longer a question of technical feasibility or economic viability, but of political will.” – November 2017 report by Lappeenranta University of Technology and Energy Watch Group

For a simple and accessible explanation of renewable energy, see this fact sheet from The Climate Reality Project: Climate 101: What is Renewable Energy?

Global Energy System Based on 100% RE Power Sector

This report by Lappeenranta University of Technology (Finland) and Energy Watch Group (Germany) models a global energy system based on a 100% renewable energy power sector. The authors find that a global transition to 100% renewable electricity is feasible at every hour throughout the year and more cost effective than the existing system, which is largely based on fossil fuels and nuclear energy. As the report concludes, “Energy transition is no longer a question of technical feasibility or economic viability, but of political will.” The report is part of a larger study analyzing the entire global energy system, including electricity, heat, mobility, desalination and industrial energy demand.

Scaling up Renewable Energy Investments in Emerging Markets

This white paper by the International Renewable Energy Agency outlines a discussion of the most significant challenges to the scale-up of renewable energy investment and development that the Coalition for Action Business and
Investors Group members have encountered while delivering projects throughout the world. The paper additionally describes a selection of available tools and policies recommended by the Group to overcome these challenges.The focus is on solar and wind as the two dominant, rapidly growing technologies in the power sector that are now competitive, but the analysis could apply to other power-producing technologies as well.

Stanford's U.S. Roadmap for 100% Renewables

This groundbreaking study presents roadmaps for each of the 50 United States to convert their entire energy systems (including electricity, transportation, heating/cooling, and industry) to renewable sources including wind, water, and sunlight.

Environmental and Energy Resource Institute

This report from the Environmental and Energy Studies Institute finds that renewables accounted for two-thirds of new U.S. generating capacity in 2015 and that new renewable capacity is 3,500 times greater than new coal capacity.

Renewable Energy Benefits: Measuring the Economics

This report by the International Renewable Energy Agency provides the first quantification of the macroeconomic impact of doubling the global share of renewables in the energy mix by 2030. The report found that accelerating the deployment of renewable energy will fuel economic growth, create new employment opportunities, enhance human welfare, and contribute to a climate-safe future.

The Impact of Fossil-Fuel Subsidies on Renewable Electricity Generation

This report by the Institutional Institute for Sustainable Development and Global Subsidies Initiative, contends that fossil-fuel subsidies can act as a barrier to the development and deployment of renewable energy technologies.

World Energy Outlook 2015

In the run-up to COP21, The World Energy Outlook provided a report on the competitive position of fast-growing renewable energy technologies in different markets and implications this might have for policy. The analysis also tracks for the first time energy use by efficiency policies around the world and the ways in which product design, recycling and reuse can contribute to energy savings. Note: Energy Watch Group argues that this report does not sufficiently account for recent developments including fossil fuel divestment (see below).

Energy Watch Group on World Energy Outlook Projections

In this report, the Energy Watch Group concludes that the World Energy Outlook’s latest projections did not take into account recent developments, including measures on climate protection and divestment of finance from the conventional energy sector. Therefore, policy-makers are advised to consider the expansion of renewables well beyond the WEO projections in their energy policies in order to avoid stranded investments in future.

Will We Ever Stop Using Fossil Fuels?

Will We Ever Stop Using Fossil Fuels? is a scholarly article that concludes that activist and aggressive policy choices are necessary to drive reductions in the consumption of fossil fuels and greenhouse gas emissions.


The Solutions Project produces interactive infographics showing what 100% renewables would look like across the United States.


Projects & Initiatives

Global 100% RE

100percent renewables logo

Global 100% RE is the first global initiative that advocates 100% renewable energy. This unique campaign builds on projects that are already taking place on national, regional and local levels and steers the global discourse on renewable energy towards 100% RE as the new normal. Global 100%RE has an excellent resource e-library, with reports, videos, websites and links about renewable energy. We recommend their website as a useful starting point to learn more about renewable energy at a global scale.

Go 100% Renewable Energy

go 100 percent renewables is a virtual gathering space for anyone striving toward a 100% renewable energy energy goal, as well as those who want to learn from them. The Renewables 100 Policy Institute launched the Go 100 Percent Renewable Energy project in 2010.

The Solutions Project

solutionsProject-logoThe Solutions Project accelerates the transition to 100% renewable energy through interactive 50-state and world-wide maps. They engage the public, celebrate and convene leaders, and advance partnerships and policies that make strides on the road to 100%.

International Renewable Energy Agency

IRENA logoThe International Renewable Energy Agency (IRENA) is an intergovernmental organization that supports countries in their transition to a sustainable energy future, and serves as the principal platform for international cooperation, a centre of excellence, and a repository of policy, technology, resource and financial knowledge on renewable energy.

Renewables International Magazine

renewables international logoRenewables International is an online portal provides a broad range of stories, news and articles about renewable energy. With a section on 100% renewables, this website is an important source of information that is often not covered by the mass media.

Solar Action Alliance

Solar Action Alliancesolar-action-alliance-logo is a website that educates visitors about opportunities to get involved with solar. They write an energy blog, have launched a petition, and provide U.S. state-specific solar infographics.
