November 2020 was the warmest since weather records began, according to figures from the EU's Copernicus Earth observation program. Solar radiation was almost exactly within the target, but the wind blew much less strongly. "A moderate month for renewable energies, but this is not enough to use up the good buffer from the previous months," says Markus W. Voigt, CEO of aream Group.

Only 84 percent of the expected wind volume blew over Germany in November 2020. "This is a very low output for a November; the autumn months are usually windier", says Voigt. The sun, on the other hand, shone steadily and reliably, and 99 percent of the expected production was achieved in Germany. Spain and Italy, on the other hand, recorded lower values than expected at 92 percent and 97 percent respectively.

"Investors are always well advised not to rely on just one source of energy and one location", says Voigt. After all, as in this November, monthly results can fluctuate, sometimes sharply. In contrast, a portfolio of different energy sources at different locations in the renewable energy sector compensates for these fluctuations. "In addition to energy production, new investment opportunities are constantly emerging in the field of renewable energies - in the entire cleantech sector", says Voigt. However, it is not easy for many investors to take advantage of these opportunities.

This is mainly because many of these new products were developed by young companies. "As a rule, these start-ups are not listed on the stock exchange and can therefore only be invested via private equity vehicles", says Voigt. But they are certainly interesting, especially for investors with a long-term perspective.
