New Upgrade component for machines : "energy throttler".
This reduces energy consumption by a factor of 4...and slows the machine down by a factor of 2.5.
Example : Apply an overclocker to a machine. 4x more energy consumption, 2x more speed. You notice the machine is consuming too much power. So you put an energy throttler on the machine. Now it runs at 80% of the speed it originally ran at before you voided the warranty on the machine, and it has the same power consumption.
You apply an overclocker again when you have more power. 4x more energy consumption, 1.6 times more speed. But then someone in your base wires a gregtech machine to high voltage, and blows some generators. So you apply another throttler. Now the machine runs at 64% of the original speed when new. Maybe it's time to sell the machine to other players....
