The diagram gives information about energy produced by three kinds of renewable energy sources over a year. Overall, it is evident that the amount of energy produced by wind-powered stations declines in that period, whereas the other sources reach the same value at the end of the year, having significant fluctuations in the process.
At the beginning of the year, wind energy production stands at 800TWh. This measure keeps declining until May, reaching nearly 300 TWh. It then fluctuates between 350 and 450 TWh before dropping further down to 200TWh in October. However, after a final surge in the following month to just over 400TWh, wind energy production plummets to 200TWh in December.
Hydropower energy produced in January is equal to 800TWh. This value fluctuates significantly throughout the year, peaking at nearly 1400TWh in November and reaching its lowest points of 600TWh in October. However, at the end of the year, energy production returns back to its initial level.
Solar energy production was registered at 200TWh at the beginning of the year but dropped to almost zero in February. However, this figure started growing continuously, peaking at 800TWh by late summer. Following that, solar energy production declined steadily and became almost negligible by December.
