Embodied energy[1] on Mars is the measure of all the energy required for the preparation of products or services. It allows for a useful comparison of various materials in the design of martian habitats.

Plastics, for example, have a high value of embodied energy and therefore are not the best choices for construction materials, of other choices are available.
Aluminium requires much more energy than Steel or iron and therefore is less likely to be used for construction on Mars.
Photovoltaic (PV) Cells Type | Energy MJ per m2 | Carbon kg CO
2 per m2 |
Monocrystalline (average) | 4750 | 242 |
Polycrystalline (average) | 4070 | 208 |
Thin film (average) | 1305 | 67 |
PV cells require very high amounts of energy to manufacture and are likely to be more economical to transport from earth in the earlier stages of a colony.
