If Ireland's current wind power capacity is 4130 MW, and the actual usable output is 30% of this, if overall average demand increases by 1 TWh/year for the next 5 years, by what percentage would wind generated power need to increase each year, on average, to meet the total increase in demand? (Assume a year is 365.25 days) O a. 30.6% O b. 9.2% C. 46.0% O d. 12.1% O e. 2.0%
