It does not take 4000 homes worth of energy for a Tesla Semi

An Oxford study said that it would take the power of 4000 homes to charge a Tesla semi. I ran the numbers myself and found that solar panels on 5 or 6 rooftops would supply enough energy for a Tesla Semi's annual needs (link). The Oxford study seems to be framed to put the Megacharger's needs into as negative a light as possible.

Clean Technica agrees with you.
Another claim is that the Tesla truck will take the power of 4,000 homes to recharge. The largest Tesla Semi battery pack is believed by many to be 1,000 kWh. An average US home uses about 30 kWh a day. That would make a full recharge equal to the average daily energy use of ~33 US homes, not 4,000. Yes, power at any given moment is different — and the Tesla Semi is powerful and can reportedly charge using Megachargers — but much more relevant is energy use (and articles like the one mentioned above mislead people into thinking the truck uses as much energy as 4,000 homes).
