HOW IT WORKS

1. Add power plants with + and −. Then press Run the day to see every hour from midnight to midnight.
2. The white line is how much power the town needs. If the bars don’t reach it, that hour has a blackout (red).
3. Solar only works when the sun is up. Wind comes and goes. Hydro and nuclear are steady. Batteries save spare power for later.
4. Gas and coal turn on whenever they’re needed, but they burn fuel and make CO₂, which warms the planet. Coal makes the most.
5. ⭐ No blackouts within budget. ⭐⭐ Also meet the CO₂ goal. ⭐⭐⭐ Also use half the CO₂ goal or less, with at least 2 million to spare.
