That is of course absolutely true. But fossil fuels are still a tool of power that is used for political purposes. Of course, this also applies to the metals needed for batteries, for example. However, access to this is not so promising in terms of power, because on the one hand, as you say, you can also live and produce "according to the times of day". On the other hand, there are untapped reserves of these raw materials - such as cobalt and manganese - in the deep sea, i.e. international waters. In short, I do think that some players have an interest in boycotting solar energy and other renewable energy sources in favor of fossil fuels in order to maintain their power base - Russia, for example.
