Unreasonable high CPU usage (90-100%)

Go to the Start Menu > right click on Computer > Advanced system settings > Advanced tab > click Environment variables. I don't use Windows anymore, but it was there when I used Windows 7.

thank you, although I still do not know what to do next
this is a snap shot of my screen.
Is 25% CPU consumption normal for Wesnoth?

screenshot:

Under "User variables" click the "New..." button, then put OMP_WAIT_POLICY for the variable name and passive for the value.

Wesnoth isn't able to use more than one core, and in that screenshot there are two-ish cores being used it looks like, so it doesn't appear that Wesnoth is the only thing running that's using a significant amount of the CPU. Looking for `wesnoth.exe` under the Processes tab would probably be more specific.

Thank you for your detailed answer.
The percentage dropped to 17% when playing normally and goes up 30% when continuously scrolling.
I apologize for not replying at the earliest for I was hoping that the fan would turn off.
