9.31 Photovoltaic solar energy in Europe According to Eurostat, the yearly growth rate of renewable energy production from photovoltaic cells is, on average, 1.65 in Europe and 1.57 in Germany. However, the rate is likely to decrease with time.

The StatCrunch output shows the results for a significance test for which the alternative hypothesis is: “the average of the yearly growth rate of renewable energy production from photovoltaic cells in Germany in the last 5 years differs from 1.57”.
