the newer model releases 50% more thermal energy
the newer model releases 50% less thermal energy
there should be no difference in levels of thermal energy
the older model releases 50% less thermal energy

Explanation:

Lightbulbs convert electrical energy to light and thermal energy. A 50% more efficient bulb converts 50% more electrical energy to useful light, meaning 50% less energy is wasted as thermal energy compared to the older model.

Answer:

The newer model releases 50% less thermal energy
