Description:

• Energy Efficiency Upgrades are only reducing power by a flat .1 LF per tick. I'm guessing it's supposed to be a % as the default is a decimal. Currently, the upgrade is negligible as it would take 80 of them to have the equivalent of a single solar generator.

Steps to Reproduce:
Easy way to tell is to fill a machine buffer to full, run it with no upgrades vs full upgrades.

That is indeed a mistake, it's already fixed in the development version, thanks for reporting!

Should be fixed in 1.8.0
