🔨 Build Power Sources

Your cursor starts in inspect mode: hover a house, plant, or line to see what it's doing. To build:

1. Pick a source: press its number key 1–5 or click it in the build guide on the right.
2. Click a tile near homes. The green lines show which homes it reaches.
3. Press Esc or right-click to go back to inspecting.

Build on open ground only, not water, houses, or roads. And good operators pause to plan: Space stops the clock, building doesn't.

📊 Read the Control Room

The bottom strip is your control room. Two panels run it.

📅 TODAY (center) is your day at a glance: the colored mountain is the power you're making, the white line is what the town needs, hour by hour. Keep the mountain above the line; a red gap means homes go dark. It also runs ahead to tonight's 19:00 dinner rush, and a chip spells out how short you'll be and what covers it: batteries or gas.

💰 MONEY (right) shows your net income per second: what lit homes pay, minus upkeep and gas fuel. When it dips below the line, your costs are outrunning your income. Catch it there before your balance feels it.

One more thing: demand keeps rising as the town grows and homes electrify. A grid that's enough today won't be enough next week.

🏭 Two Ways to Lose

Pollution: gas is cheap and runs anytime, but it pollutes. Lean on it too hard and emissions hit the cap: game over. Bankruptcy: every plant costs upkeep for as long as it stands, so an overbuilt grid bleeds cash even when idle. Let your balance sit in the red and it's over too. Grow fast, but don't choke the town or overbuild.

🏆 How to Win: Sustainable City

Run a real town entirely on clean power. You reach a ⭐ Sustainable City when you hold all of this for 90 seconds:

• 50 homes powered
• no homes going dark: the grid keeps up all night
• no gas burning: sun, wind, nuclear & batteries only
• enough always-on backup for the peak: nuclear, batteries, or a gas reserve that could ride out a windless night
