Which type of energy usage aspect can fluctuate throughout the year in a home?

Seasonal energy usage refers to the variation in energy consumption that occurs due to changes in climate and weather conditions throughout the year. Homes typically experience fluctuations in energy use based on seasonal demands; for example, heating requirements in winter and cooling needs during summer can cause significant variations in energy consumption.

This type of energy usage can be influenced by factors such as temperature, humidity, and even the number of daylight hours, leading to increased use of heating systems or air conditioning systems during peak seasons. In contrast, baseload energy usage represents the constant minimum level of demand for energy that a home requires throughout the year and does not fluctuate significantly. Similarly, quarterly maintenance energy usage and minimal use appliance energy typically remain more stable, as they do not vary greatly with seasonal changes.
