Within the context of sustainable design, energy efficiency is regarded as an important key to reducing fossil fuel use by improving the energy performance of equipment and appliances, buildings, and municipal infrastructure. Many energy experts today regard continued dependence on coal, oil, and natural gas to be unsustainable because supplies are not limitless and combustion of fossil fuels results in a variety of negative environmental impacts including air and water pollution and significant carbon dioxide emissions.
