Comparison of the most important investment forms 

A wind farm on the Finnish coast is harvesting wind, no matter how the DAX opened this morning. Not least, this independence from the stock market has firmly established wind power as a financial investment. However, as the company’s standing increases, so does the range of investment forms that differ radically:

  • Direct investments often bind capital to a single location for two decades.
  • Open-end funds can spread it across a continent.
  • Thematic funds reconnect wind power to the stock market, including fluctuations. 

In this article, we show you which shapes you should know and which of them might suit you.

Disclaimer: Plants from 100 kW have been obligated to direct marketing for years. The EEG market premium is paid in addition to the market price achieved. So both paths do not rule each other out, but interlock.
