Around the world, governments apply subsidies and taxes across energy sources to create a mix of incentives and disincentives that influence energy prices and emissions worldwide.
With our latest update to the En‑ROADS Simulator, co-developed with MIT Sloan, you can now explore the current levels of subsidization and taxation for each energy source in the advanced views and test out scenarios for removing or adding to them.
On the main view of En‑ROADS we have also updated the slider labels to focus on whether an action encourages or discourages the energy source to make the simulator more accessible to a wider audience.
Alongside these changes, there are new graphs and advanced sliders to help you create scenarios and understand the impacts of price adjustments across coal, oil, natural gas, bioenergy, nuclear, and renewables. Test how shifting support across energy sources affects emissions, costs, and energy use:
This update is designed to add a new layer to your En‑ROADS workshops, games, and discussions by grounding conversations in today’s policy environment while offering the opportunity to test alternative scenarios. If you want to go deeper, our explainer includes guidance on the new features and how to use them in practice.
With these new features you can:
Explore what happens when energy subsidies are shifted toward renewables rather than eliminated.
Compare the climate and economic impacts of encouraging or discouraging different fuels.
Watch a summary and demonstration of the new update in En‑ROADS.
On Thursday, April 23, at 11 AM ET, our team will introduce this update, offer facilitation tips for incorporating it into your next event, and answer your questions live.
We’re grateful to everyone who contributed to this update. This work builds on recommendations from the MIT Climate Policy Center, Yale Program on Climate Change Communication, International Institute for Sustainable Development (IISD), and others. It also benefited from review and testing by colleagues, En‑ROADS Climate Ambassadors, and energy experts from institutions including Arizona State University, Brazilian Development Bank, IISD, Alliance for Market Research, MIT, Reutlingen University, and Earth Track.
