Reduced Greenhouse Gas Emissions
Answer
Energy efficiency measures — such as using more efficient appliances, improving insulation in buildings, and optimizing industrial processes — reduce the amount of energy needed to perform a specific task. In other words, when we use energy more efficiently, it decreases the demand for energy production. This means that less fossil fuel or other carbon-intensive energy sources are burned to meet our energy needs, leading to lower greenhouse gas emissions, particularly carbon dioxide (CO2).
