I don't get it what the 37.3 kWh are supposed to mean in this context. This is for sure not the energy required to keep a person 'alive', but all energy (manufacturing, transportation, ...) assigned to per person. The energy consumption for a physical working person is approx 4000 cal per day (4.6 kWh). According to [1] it takes about 150 BTU (0.043 kWh) per hour / ft^2 to melt snow. To clear/melt an area of 5*15 meter this requires about 35 kWh. (I have rough calculation of the energy required to melt 20 cm of -5°C cold snow and get a four times higher energy requirement, probably i have missed something.)
