Energy efficiency saves money by decreasing the energy required to complete tasks, while also lowering emissions and relieving pressure from key infrastructure such as power grids and critical systems.
Efficient technologies, appliance and vehicle standards, and behavioral changes all play a part in making our world more energy efficient. Buildings and light vehicles have seen notable advances in energy efficiency.
Save Money
Energy efficiency can help cut electricity costs and air pollution, while simultaneously decreasing the need for new power plants, which contribute heavily to climate change.
Energy efficiency upgrades can bring many advantages for both homes and businesses of any kind, from replacing light bulbs to improving insulation – from saving money over the lifetime of equipment to significant utility savings.
Energy efficiency benefits can be seen across income levels, but are especially valuable to low-income households as lower energy costs help cushion them against unpredictable price spikes in energy.
Drafty homes waste up to 40 percent of energy they use and could save hundreds annually by sealing leaks, installing insulation and upgrading heating and cooling systems. And inefficient vehicles tend to spend significantly more on fuel than their more efficient counterparts; using the Energy Star label helps consumers identify energy-saving products which could save them money over the course of their lives.
Save the Environment
Energy efficiency is one of the easiest and fastest ways to decrease our dependence on fossil fuels, while simultaneously helping lower greenhouse gas emissions and demand for imported energy imports while simultaneously cutting household electricity bills.
Efficiency improvements have played a pivotal role in global carbon dioxide levels decreasing over time. At COP 28 climate conference, countries committed to working collaboratively towards doubling energy efficiency improvements by 2030.
Building with energy-saving practices helps homeowners and offices save energy while saving money, improving indoor air quality and protecting against mold or mildew growth; all while decreasing environmental impacts.
Investment in efficient public transit systems like Medellin’s is another effective way to both protect the environment and create local jobs. Since these jobs cannot be outsourced or automated, they remain within their respective communities as sources of income for those who otherwise may struggle with finding employment.
Save Lives
Energy efficiency measures not only save consumers money, but they can also promote health and wellbeing. For instance, upgrading homes with energy-efficient upgrades makes their environment warmer, drier and better ventilated – helping prevent illnesses like asthma, allergies and mold growth.
Energy-efficient practices also lower greenhouse gas emissions and climate pollution, both of which threaten human health. At NRDC, we work to promote policies and programs that encourage energy efficiency on local, state and national levels – such as creating a standard label to identify appliances and buildings with high levels of efficiency; working with cities to cut energy waste in larger buildings; encouraging utilities to support efficient products.
Energy efficiency improvements can be one of the least-expensive ways to strengthen our nation’s economy, according to ACEEE. A 15% improvement by 2030 could yield $520 billion of economic benefits, including job creation and lower electricity bills for businesses and households alike.
Save the Economy
Energy efficiency reduces costs for consumers who enjoy lower utility bills and equipment investments, reduced pollution from power plants and energy intensive industries, as well as enhanced comfort, health and safety in homes and offices.
By improving efficiency in buildings and appliances, manufacturers can reduce production costs, making their production more cost-competitive globally while simultaneously creating jobs and stimulating the economy.
Energy efficiency programs tend to be less risky than investing in additional generation capacity, which is especially relevant in developing nations with uncertain climate policies.
Energy efficiency also saves money for utilities by helping avoid investment in new infrastructure to meet increased demand, as well as helping stabilize energy prices and reduce risk. Governments and utilities around the world are increasingly turning to energy efficiency as part of their plan to combat climate change; when combined with renewables and storage solutions it offers one of the quickest and least expensive means of meeting climate targets.
