I believe snow could be moved with far less energy.
Today's snow ploughs use a lot of force.
But perhaps with better engineering, new ways to move snow could be invented - for example conveyor systems that move and compact the snow.
Theoretically you can generate power by compacting snow, since the stuff at the top has gravitational potential energy and gives it up when compacted down. Find a way to collect that, and your snowploughs won't need any recharging.
