In addition to oxygen, in Astroneer there is another important resource - energy (or power). Your backpack has a large orange glow bar that powers your astronaut's lights. Over time, it slowly recovers, but if you create a decent power grid and stay in touch with it, the scale will rebuild much faster.
- By crafting solar panels in your backpack, you can attach them to the top of your backpack while getting power in daylight.
- Use a wind turbine to generate power during storms.
- Generators can convert organic matter into energy when there is no sunlight or wind.
- Get energy from orange-glowing microorganisms underground and in the field.
- Batteries can store excess energy that can be used when there is no sunlight, wind, or power generators.
- You can attach these generators to vehicles and buildings to maintain their power, and each one needs its own supply. Sometimes when a building refuses to work, it might be because you are running out of energy.
