The worldwide installed wind power in 2012 was 280GW. Assume that the total electricity generation worldwide is 20200TWh per year, and a capacity factor for wind power of 30%.
Excellent answers
To find the percentage of total electricity generation worldwide covered by wind energy in 2012, we need to divide the installed wind power (represented in GW) by the total electricity generation (represented in TWh) and multiply by 100.
First, we need to convert the installed wind power from GW to TWh by multiplying it by the capacity factor (30%).
Installed wind power in TWh = installed wind power in GW * capacity factor
Installed wind power in TWh = 280 GW * 30% = 84 TWh
Now, we can find the percentage by dividing the installed wind power (84 TWh) by the total electricity generation (20200 TWh) and multiplying by 100.
Percentage = (Installed wind power / Total electricity generation) * 100
Percentage = (84 TWh / 20200 TWh) * 100
Percentage ≈ 0.4158 * 100
Percentage ≈ 41.58%
Therefore, wind energy covered approximately 41.58% of the total electricity generation worldwide in 2012.
