Answer:
b- 232%
Explanation:
Renewable energy consumption by energy source in 2006 = 6.659 quadrillion Btu
Renewable energy consumption by energy source in 2010 = 8.049 quadrillion Btu.
In 2006, wind energy = 4%
∴ wind energy = 4% x 6.659 = 0.26636
In 2010, wind energy = 11%
∴ wind energy = 11% x 8.049 = 0.88539
∴ Percent increase = (final number - initial number) ÷ (initial number) x 100
% increase = [(0.88539 - 0.26636) ÷ 0.26636} x 100 = 232.4035% ≈ 232%.
Answer = 232%.
