What would you like to explore?
| Tool | Your question | Scale and format |
|---|---|---|
| Electrify | Can I keep the lights on while cutting emissions and paying the bills? | A utility in a selected location. Build plants, set prices, and manage costs in a free browser game for computers and phones. |
| En-ROADS | Which combinations of climate solutions could limit global warming? | Global energy, land, economy, and climate. Change policies and assumptions, then compare possible futures through 2100. |
| Energy Transition Model | What could a country, region, or city's future energy system look like? | A selected area and future year. Try changes to energy supply, demand, and storage, and inspect their effects on costs and emissions. |
| Energy Policy Simulator | How could a policy package affect emissions, the economy, and public health? | Available country and regional models. Test policies such as carbon pricing or efficiency standards across electricity, transport, buildings, and other sectors. |
We make Electrify and wrote this guide to help you choose. We’re independent of the other projects; this comparison does not imply their endorsement.
Know what each result can tell you
Select a tool’s name above to open it. For Energy Transition Model and Energy Policy Simulator, check that a region relevant to your question is available.
Read results alongside each model’s geography, time periods, and assumptions. Electrify uses one representative day per month and tracks emissions without calculating global temperature. Our En-ROADS comparison explains how a game about running a utility can complement global climate exploration.
For the other tools’ assumptions and tutorials, read the En-ROADS user guide, Energy Transition Model documentation, and Energy Policy Simulator documentation. Teachers can also try our classroom activity.
