Mr. Li went to the administrative center building of a city for business. Assuming that going up one floor by elevator is denoted as $+1$, and going down one floor is denoted as $-1$. Mr. Li started from the 1st floor, and the floors he went up and down on the elevator are recorded in order as follows (unit: floor): $+5$, $-3$, $+10$, $-8$, $+12$, $-6$, $-10$. <br/> $(1)$ Please explain by calculation whether Mr. Li finally returns to the starting point, the 1st floor; <br/> $(2)$ The height of each floor in the center building is 2.8m, and the elevator consumes 0.1 degrees of electricity for each meter it goes up or down.
