What might be a consequence of a poorly insulated house?

A consequence of a poorly insulated house is increased fuel consumption. When a house lacks proper insulation, it allows heat to escape during the winter and lets warm air in during the summer. This results in heating and cooling systems working harder to maintain the desired indoor temperature. Consequently, more energy is required to provide heating in colder months, leading to a rise in energy consumption. This increase in fuel usage not only raises energy bills but can also contribute to higher greenhouse gas emissions if fossil fuels are used. In contrast, a well-insulated home retains heat more effectively, thereby reducing the amount of fuel that needs to be consumed for heating or cooling.
