How many kilocalories of energy would you expect a person in contemporary England to consume daily (including food, transportation, household use, etc.)?

A person’s total daily energy use includes far more than the roughly 2,000 food kilocalories they might eat. When transportation, household energy, and other uses are included, the amount is on the order of hundreds of thousands of kilocalories per day, so “hundreds of thousands” is the best answer.
