Hi,
The largest energy consumer at home among the options provided is typically:
B: space heating
Space heating, especially in colder climates, tends to be one of the most significant energy consumers in households. It requires a substantial amount of energy to maintain comfortable indoor temperatures during the colder months. Proper insulation (option A) can help reduce the energy needed for space heating, but heating itself is often the largest contributor to home energy consumption. Lighting (option C) and driving a car (option D) are also energy consumers but are generally smaller in terms of overall household energy use. Option E, "cat memes," is not a factor in household energy consumption.
