Which of the following could be a part of an energy assessment provided by Efficiency Maine?

An energy assessment provided by Efficiency Maine would include an evaluation of heating and cooling efficiency. This is a fundamental component of energy assessments, as they focus on identifying how effectively a home manages its energy use, particularly in terms of heating and cooling systems. These evaluations help homeowners understand if their systems are operating efficiently, which can lead to recommendations for upgrades or improvements that might be necessary to enhance energy savings and comfort. Efficiency Maine works to promote energy efficiency, thereby making heating and cooling evaluations a key aspect of their assessments.

In contrast, the other options do not align with the core objectives of an energy assessment. Household budgeting is more related to personal finance than energy efficiency, home insurance pertains to risk management rather than energy use, and marketing strategies for home sales do not connect to energy assessments, which focus on how to optimize energy consumption and reduce costs for homeowners.
