Step 1: Convert the efficiency from percentage to a decimal.
$$ \text{Efficiency} = 80\% = \frac{80}{100} = 0.80 $$
Step 2: Use the formula for efficiency to calculate the output power.
$$ \text{Efficiency} = \frac{\text{Output Power}}{\text{Input Power}} $$
$$ \text{Output Power} = \text{Efficiency} \times \text{Input Power} $$
$$ \text{Output Power} = 0.80 \times 100 \text{ W} $$
$$ \text{Output Power} = 80 \text{ W} $$
The output power is 80 W.
$$ \boxed{80 \text{ W}} $$
