Microsoft Edge using double the average energy impact as compared to chrome on Mac

For finding out that does Edge use much more battery,i restarted my mac and immediately launched both Google Chrome and Microsoft Edge and i have same extensions on both .I then opened the same webpages and duplicated them using the same extension in both(Chrome and Edge) and after all the tabs got loaded i just went to activity monitor and found out that Microsoft Edge Helper is using 85% of CPU whereas Chrome uses much lesser CPU,and then i found out that the average energy impact of Edge was double of chrome.
