Energy Efficiency and Conservation

Energy efficiency and conservation encompasses the strategies and practices aimed at reducing overall energy consumption. Energy efficiency refers to using less energy to perform the same task, typically through technological improvements like high-performance insulation or fuel-efficient vehicles. In contrast, energy conservation involves reducing energy consumption through behavioral changes, such as turning off lights when leaving a room or adjusting thermostats. Together, these approaches are fundamental to lowering energy costs, enhancing national energy security, and minimizing the environmental footprint of energy use, particularly greenhouse gas emissions.
