After the EU just agreed on a partial embargo for Russian oil, renewable energies showed in the past month that they consistently contribute their share to the energy supply. This year, May brought Germany plenty of sunshine: High air pressure made for a proverbial "merry month" and a very good solar power yield.

Photovoltaics in Germany exceeded its target by four percent in May 2022, and in Spain by as much as five percent. Only Italy was behind plan last month, with eight percent. "All in all, the result is a precision landing: One hundred percent of the target was achieved across Europe", says aream CEO Markus W. Voigt. 

The aream Group is also satisfied with the wind yield: despite the very nice weather and a somewhat lower wind volume, the target values were achieved 97 percent of the time. Thanks to the strong wind months at the beginning of the year, the yield since the beginning of the year is 103 percent. "Even if there are more below-average wind months again, this means that the forecast yield for the entire year is easily achievable", says Voigt. 

For investors, this also means that the planned yields can be optimally achieved within a mixed portfolio of wind and solar farms, project development and operation. "May showed that a broad diversification of renewable energy investments across types and regions is most effective", Voigt said.

At the same time, the ever-closer interconnection of countries in Europe is ensuring that electricity from renewables is increasingly well distributed. "The further the expansion of the grids progresses and the more intelligently these grids can be controlled, the less fossil fuel power plants will be needed as buffers for peak loads", Voigt says. This is where investments in renewable energies will focus in the coming years, in addition to the pure expansion of capacities. "Storage solutions and also the technology for intelligent distribution of electricity are crucial variables for the desired independence from fossil fuels", says Voigt. "A lot of research will be needed here and a lot of money will be needed to move forward quickly."
