A family has a furnace that uses natural gas to heat their home. They are moving to an area that offers the option of using energy from a solar power plant to heat their home. Which disadvantage will the family most likely face by making this switch?

Solar power depends on sunlight, which varies with weather and is unavailable at night, so the supply of energy for heating is less consistent than natural gas. The family may need backup energy or storage to keep the heat reliable. This makes “a less reliable production of heat” the most likely disadvantage; the other choices are not inevitable results of switching to solar energy.
