"Net energy" is what is finally usable,
after all the waste energy has been subtracted.

• efficiency
• number of steps
• like the energy pyramid
• systems view

Example calculations

STEPS & EFFICIENCY	step 1	step 2	step 3	Overall Efficiency
2 steps of 85%	85% x	85% =		72%
3 steps of 80%	80% x	80% x	80% =	51%
3 steps of 70%	70% x	70% x	70% =	34%
3 steps of 30%	30% x	30% x	30% =	2.7 %
