What type of energy efficiency improvements can benefit both the environment and homeowners?

Upgrading to LED lighting and appliances is a highly effective energy efficiency improvement that benefits both the environment and homeowners. LED lighting uses significantly less energy compared to traditional incandescent bulbs, resulting in lower electricity consumption. This not only helps in reducing utility bills for homeowners but also decreases the overall demand on power plants, contributing to a reduction in greenhouse gas emissions and environmental pollution.

In addition, energy-efficient appliances, such as those certified by ENERGY STAR, use advanced technologies to consume less energy and water. This further lowers household energy costs while minimizing the environmental impact associated with energy production. As a result, homeowners enjoy both economic advantages and the satisfaction of contributing to a more sustainable future.

In contrast, the other options do not align with beneficial energy efficiency improvements. Installing solar panels can be part of a comprehensive energy strategy but relies solely on one method without considering other improvements. Maintaining outdated heating systems and increasing reliance on fossil fuels would likely lead to higher energy use and increased emissions, which are neither beneficial for homeowners' finances nor for the environment.
