Large RAM used by windows10 on PD14

[Widechan]

My mbp has 16G RAM totally and 4G assigned for windows. When I opened windows10 on parallels desktop14, it often showed that windows10 used more than 2G RAM, sometimes more than 3.5 or 3.8G. In addition, PD14 shows a high energy impact in activity monitor, more than 60, sometimes more than 90, so fan runs so fast and mbp so hot. Is there a problem? And, what can I improve it?
Any suggestions will be welcome and appreciated!
