Which equation best represents net energy?

• net energy = energy output + energy input

• net energy = initial low-quality energy – final high-quality energy

• net energy = energy input – energy output

• net energy = energy output – energy input

• net energy = high-quality energy + low-quality energy

What would NOT make an energy resource with a low net energy more competitive in the marketplace

• subsidies

• tax breaks

• full-cost pricing

• technology improvements

• affordable pricing
