Energy System

Overview

The energy system is the central ongoing challenge in Outbound. The camper van's electric motor, workstations, lights, and appliances all draw from a shared battery. If the battery drains completely, the van stops moving and powered equipment shuts down until power is restored. Players start with a basic bio burner and progressively unlock renewable sources through the technology tree, eventually building a fully self-sufficient power grid. This progression from burning resources to generating clean energy represents the game's core sustainability theme.

The Battery

The van has a single battery that powers everything. Early in the game, managing battery levels is a constant concern. As players unlock upgrades, battery capacity increases and surplus power from efficient setups feeds into reserves for nighttime or high-consumption periods. The energy meter on the van's dashboard shows current charge, and keeping an eye on it is essential when planning longer drives between biomes.

While driving, players also need to monitor motor heat levels. The driving system tracks both charge consumption and motor temperature, creating a balance between speed and efficiency.

Power Sources

Four energy sources are available in the game, each with different characteristics.

Bio Burner

The bio burner is the starting power source. It burns biodegradable materials to charge the battery.

Small logs can be picked up by hand, while larger logs require an axe. The bio burner is mounted in the back of the vehicle and works anywhere, making it reliable but resource-intensive. Early gameplay revolves around a loop of gathering fuel, traveling, and gathering more.

Solar Panels

Solar arrays unfold from the van's exterior and generate power during daylight hours. Output depends heavily on conditions.

Solar energy is the most intuitive renewable source but requires supplementation during night and storms. It pairs naturally with wind turbines for round-the-clock coverage.

Wind Turbines

Wind turbines generate power regardless of time of day. They need elevated positioning and open terrain for optimal performance. Placing a turbine on top of the van or on high ground works best; sheltered valleys reduce output. Wind conditions vary by biome and weather. Windmill sound effects were added in alpha v0.5.6, and the feature was present from the earliest playable builds.

Hydro Generators

Water-powered generators harness flowing rivers and streams for steady output. The energy is consistent as long as the van is parked near running water, but this restricts parking location choices. Rivers and lakes were added to the map display in alpha v0.5.8, making it easier to plan routes that include hydro-friendly parking spots.

Power Source Comparison

Energy Progression

The intended progression path moves players from dependence on the bio burner toward a fully renewable setup.

1. Early game: The bio burner is the only power source. Gather fibre and lumber constantly to keep moving.

2. Mid game: Unlock solar panels and/or wind turbines through signal tower blueprints. Supplement the bio burner with renewables.

3. Late game: Build a mixed renewable grid (solar + wind + hydro depending on location) that eliminates the need for burning resources. Battery bank upgrades store surplus for nighttime and high-draw activities.

Energy Strategy by Biome

Different regions reward different power configurations.

• The Outdoors: Forests provide plentiful lumber for the bio burner. Open plains suit wind turbines. Mountains offer elevation for improved wind performance.

• The Coast: Coastal breezes benefit wind turbines. Rivers and streams near the shoreline support hydro generators. Sunny beaches are good for solar, though coastal weather can be unpredictable.

Energy and Other Systems

Energy affects nearly every part of gameplay. Crafting workstations draw power to operate. Cooking stations need electricity. The van's headlights (nighttime driving was added in beta v0.7.6) and interior lights consume charge. Even storage upgrades and the pop-up camper mode add to the van's overall power draw. Managing energy is not a one-time setup; it is an ongoing part of the gameplay loop that keeps players engaged throughout their journey.
