A science journalist is analyzing the impact of solar panel installations. If the efficiency of solar panels improves by 2% annually and the current efficiency is 18%, what will the efficiency be in 15 years? Use the formula for exponential growth: \( E(t) = E_0 \times (1 + r)^t \). Calculate \( E(t) \).
