Not really efficient. 2.5mA is waaaaaaay too much current for a digital application.

Mostly correct CMOS. For correct operation, turn the power supply down to 5V or adjust the logic 1 level up to 8V. (To adjust logic level, you have to place a logic gate on the canvas. Minor bug in EC.) The inefficiency only happens because +5V is not close enough to +8V for the transistors to switch properly. Also, you may want to turn the LED current down to 5mA, but it's better to use another transistor to drive the LED. When you make more complex gates, the load of an LED can affect the gate's operation.
