Actually, surprisingly, fast inserters use less energy than regular. Fast inserters have a higher power usage while moving, but they're so much faster that they move for much less time and overall use less energy to get the same job done.NeoForce wrote:You don't need fast inserters, just use regular inserters for this. It uses less energy
Someone has done a test using an accumulator powering inserters moving items and the fast inserter can move more items than the regular for the same stored energy. There was a thread somewhere, which hopefully someone else can find.
