Which consumption type varies with outdoor temperatures?

Seasonal consumption is the correct answer because it refers to the variations in energy usage that occur in response to changes in outdoor temperatures over the course of different seasons. For example, during the colder months, energy consumption typically increases due to heating needs, while in warmer months, there may be a rise in usage from air conditioning. These patterns are directly influenced by outdoor climate conditions, indicating that seasonal consumption ebbs and flows in relation to temperature changes.

In contrast, peak demand represents the highest level of electricity usage during a specific time period, often driven by factors like weather extremes or time of day, but it does not necessarily capture the broader seasonal variations. Baseload consumption refers to the minimum level of demand on an electrical grid over a 24-hour period and remains relatively constant, regardless of temperature fluctuations. Controlled consumption is generally associated with programs that manage energy usage during specific times, usually to mitigate peak demand, without directly relating to seasonal temperature changes. Thus, seasonal consumption stands out as the type that is most clearly affected by outdoor temperatures.
