Type 0 Civilization

A Type 0 Civilization, as you can imagine, is one that has not yet been able to harness all the energy of its home planet. It is, therefore, a sub-global one that harnesses power from raw materials.interestingengineering.com
Type 1, as defined by Kardashev, is one still limited to one planet. But, critically, to have reached this level on the scale, the civilization must be able to harness all the energy available there.
For them, nuclear fusion is probably child's play as well as harnessing the antimatter. Other power sources from geothermal to other renewables would also be a given. Try to think of something like the planet Coruscant in the Star Wars Universe (but without the larger Republic/Empire), or the great works of Asimov.interestingengineering.com
