Can a simple act like switching out a light bulb help in the battle against global warming? Of course, it will take more than just switching to energy-efficient LED light bulbs to stop the effects of global warming and rising sea levels. However, energy efficiency is an effective but frequently undervalued method of decreasing waste and pollution.
Despite a 30 percent increase in GDP, U.S. energy consumption is almost unchanged since the year 2000, thanks to efficiency improvements. In fact, during the last four decades, energy efficiency has done more to satisfy America's energy demands than oil, gas, or nuclear power.
What Exactly Is Energy Efficiency?
Although they share the same aim, energy efficiency and energy conservation are two distinct strategies for accomplishing the same thing: cutting down on energy use. See this for the distinction. Individuals may help save energy by reducing their use of energy-intensive products and services, such as lights, vehicles, and appliances. To keep the lights on, the car running, and the washer and dryer spinning while using less energy, energy efficiency makes use of technology to prevent or minimize energy waste. Better management of energy use is the key.
Why is it important to use less energy?
saving money and helping the environment by reducing energy use via efficiency techniques. Energy efficiency benefits the environment since it reduces the overall quantity of energy used. A new hydroelectric dam, for example, may prevent migratory salmon from passing through an area, reducing air and water pollution caused by electricity production and preventing harmful effects on critical ecosystems.The electricity grid may also benefit from this.
Cutting carbon pollution
Increasing the efficiency of our homes, automobiles, and other energy-consuming devices is a low-cost, low-impact way to make a big difference in the fight against climate change. Carbon dioxide (CO2) emissions may be reduced significantly via improved housing efficiency. By 2050, widespread use of energy-efficient appliances, electronics, equipment, and lighting, together with improved insulation and other weatherization measures, may reduce annual carbon pollution by 550 million metric tons, which is equivalent to the electric power emissions generated in Texas, New York, Florida, Illinois, Virginia, and California in 2016.
Creating Jobs
More than 2.2 million people in the United States are employed in some capacity related to energy conservation or renewable power generation. More than five times as many people would be employed if we switched away from coal, natural gas, and oil. Approximately 1 in 6 construction jobs in the United States is directly related to energy efficiency.
Lowering Bills
Investing in energy-efficient equipment may reduce annual utility costs for the average American family by up to $500. According to 2016 rankings, residents of the five least efficient states had their energy bills rise by twice as much as those in the five most efficient states (California, Oregon, Connecticut, Vermont, and New York). These states are Wyoming, North Dakota, Alabama, South Dakota, and Mississippi. The energy burden, or percentage of income spent on energy, is three times greater for low-income urban families than it is for higher-income households, in part because of the absence of weatherization in the former. In a similar vein, low-income rural families have an energy burden that is approximately three times that of other rural households.
Improving Lives
Energy efficiency has been linked to improved health and longevity. Saving six lives per day and up to $20 billion in health-related issues might be achieved by reducing national energy use by 15 percent for one year via efficiency measures. Small particles released into the air by the combustion of coal, oil, and natural gas in power plants have been linked to asthma, heart attacks, and lung cancer. Respiratory problems may be exacerbated by a lack of proper ventilation and weatherization within the house. The fact that energy efficiency may also boost daily comfort is an advantage that may be overlooked in cost-benefit analyses.
Strengthening Independence
Increasing energy efficiency on a national scale has the potential to strengthen energy security by building a more reliable power infrastructure and reducing reliance on volatile fossil fuel imports.
Examples of energy efficiency
Are you prepared to join the green energy movement? You can help in big and little ways, and I've included both below.
Get Smart About Energy Use
You may begin with baby steps like turning off devices, altering TV and thermostat settings, and establishing timers. Identify and eliminate any "energy vampires" in your home.
Purchase Energy-Efficient Home Appliances
By choosing Energy Star-certified appliances, you may reduce your power bill by $4.50 for every $1 you spend. This voluntary program is run by the U.S. Environmental Protection Agency and the Department of Energy, with more than 18,000 partners. There are almost 75 product categories that have the Energy Star designation, including major appliances, lights, and electronics.
Currently, owing to national energy efficiency regulations, the typical family may save over $500 annually by upgrading to more energy-efficient appliances; this number is expected to rise to $840 by the year 2030. Modern refrigerators consume 75% less energy than their 1970s counterparts, and after accounting for inflation, they now cost less than half what they did before. Energy Star washing machines, however, reduce consumption by a quarter compared to conventional models and by a third compared to those without the label.
The blue and white Energy Star designation has been the norm for about 30 years now to indicate the most energy-efficient products, structures, and machinery. Carbon pollution has decreased by 2.7 billion metric tons thanks to the initiative, which is the equivalent of yearly emissions from around 670 coal-fired power stations, according to estimates.
Efficiently heat and cool
If only 10% of homes purchased heating and cooling systems with the Energy Star badge, we could prevent the yearly release of 13 billion pounds of greenhouse gases or the emissions from 1.2 million automobiles. Purchasing an Energy Star-rated air conditioner, central air conditioning unit, or heat pump will save you more than $160 per year on energy costs.
To illuminate a room, modern ceiling fans with integrated lighting have earned the Energy Star badge, indicating that they are 60% more energy efficient than older models. To have the same cooling effect as a central air conditioner, a ceiling fan has to be used just 10 percent as often and use a tenth of the energy.
Where oil and gas furnaces are the norm, super-efficient electric heat pumps provide a greener and more cost-effective alternative for heating and cooling homes and businesses. Heat pumps, which are more efficient than burning fossil fuels to generate heat, transfer heat from a cool (such as the cold outdoors) to a warm (such as an enclosed structure), making the cool area colder and the warm area warmer.Heat pumps may provide enough warmth on their own in the vast majority of regions, eliminating the requirement for a secondary heating system. They are available in a variety of configurations and configuration types, and they are a far more efficient appliance for cooling than either a regular window air-conditioning unit or central air: For instance, a central heat pump may be installed in lieu of a central air conditioner and utilize the same ductwork and thermostats.
More and more individuals are buying their first air conditioners as climate change causes more harsh weather. If you want to save money on utilities without sacrificing comfort, now is the time to invest in a heat pump. The alternative is to put off thinking about a new heating system until your gas furnace or boiler breaks down, at which point you'll be forced to either replace the old gas heater with a new one or forego the advantages of switching to another fuel.
Reducing your usage of fossil fuels would not only help mitigate the effects of climate change since emissions from homes and businesses account for 13% of the country's total yearly emissions, but it would also assist the economy. In addition to improving the quality of the air inside your house, air conditioning may help relieve strain on your city's electrical system, particularly during extreme temperatures. Therefore, while a heat pump's initial cost may be slightly higher than that of a regular air conditioner without a heating function, the long-term advantages make it a great investment for your wallet and the environment.
Last but not least, when a home is properly sealed against the elements, much less energy is needed to keep it cool in the summer and warm in the winter. If you need help detecting drafts, you may either hire a professional weatherization service, contact your local utility, or take matters into your own hands. When necessary, install insulation.
Replace incandescent bulbs with LEDs
By replacing inefficient incandescent light bulbs with more cost-effective LED counterparts, each American family could save roughly $100 annually, and the country as a whole could save around $12.5 billion (assuming LEDs were widely adopted).
The most energy-efficient lighting option, LED bulbs, are available in more than 150 different variations. When compared to traditional incandescent bulbs, they may reduce your energy use by up to 90%, saving you up to $100 over the lifespan of the bulb.
Energy Efficiency: For Today and Tomorrow
Consumers have benefited from NRDC's efforts to develop and advocate for state and federal energy efficiency standards for buildings and appliances, to work with cities to reduce energy waste in larger buildings, to encourage utilities to promote efficiency, and to push for efficiency improvements in building codes. While the Trump administration has proposed cutting money for a variety of related initiatives—from weatherization aid to the government's energy research—many programs and standards aimed at increasing energy efficiency are coming under fire. The government has also proposed "reforms" to successful programs like Energy Star, which might reduce the program's impact and push back the implementation of energy efficiency regulations. Each of us may help bring about a more energy-efficient future that benefits human and environmental health by speaking out against these rollbacks and making other lifestyle adjustments.
Conclusion
Reduced carbon emissions, cheaper energy bills, and even better health outcomes in communities are just some of the numerous advantages individuals and society at large can reap from energy efficiency, which is key to developing a cleaner energy future. These objectives are also being pursued by clean energy technologies; however, energy efficiency is often the most cost-effective way to accomplish them, and the synergistic effects of renewable energy and energy efficiency are enhanced.
