I am thinking of changing my DE from GNOME to Budgie. I use Ubuntu 18.04 LTS, and might upgrade to 20.04 in a few days.
I have heard that Budgie consumes less RAM compared to GNOME. Does it also consume less power? My Dell Inspiron 15R 5537 laptop lasts only about 1.5 hours when charged to 100%.

This chart from an article at Ubuntubuzz shows, at idle with no apps loaded, Budgie uses 40 MB (4 %) less RAM than GNOME.
Once apps are loaded, the relative advantage of Budgie may change, for causes described at .
I am not aware of a power consumption comparison of different desktops. However, you may wish to consider looking into tlp and other packages dedicated to lower battery consumption. That would be the subject of another question, as your questions should be reasonably scoped.
Since different hardware has different power management capabilities, if you have power management questions, please specify the make of laptop, and its model part number (found on the serial number sticker on most laptops); "model" numbers elsewhere on laptops are generally marketing buzzwords and do not help us find the hardware manuals.
