The worldwide installed wind power in 2012 was . Assume that the total electricity generation worldwide is per year, and a capacity factor for wind power of .
What percentage of the total electricity generation worldwide was covered by wind energy in 2012?
To find the percentage of the total electricity generation worldwide covered by wind energy in 2012, we need to calculate the amount of electricity generated by wind power in that year.
We are given that the worldwide installed wind power in 2012 was X terawatt-hours (TWh), and the total electricity generation worldwide per year is Y TWh. We are also given a capacity factor for wind power of Z.
The capacity factor for wind power represents the average actual output of a wind turbine compared to its maximum potential output. Since this factor includes various factors such as weather conditions and downtime for maintenance, we can assume that wind power stations operate at an average of Z% of their maximum capacity throughout the year.
To calculate the electricity generated by wind power in 2012, we can multiply the installed wind power by the capacity factor:
Electricity generated by wind power in 2012 = X TWh * (Z / 100)
Now, to find the percentage of the total electricity generation worldwide covered by wind energy, we divide the electricity generated by wind power by the total electricity generation worldwide and multiply by 100:
Percentage of total electricity generation covered by wind energy in 2012 = (Electricity generated by wind power in 2012 / Y TWh) * 100
Plug in the values for X, Y, and Z, and calculate the result.
