Energy efficiency is an accessible, low-impact way to mitigate climate pollution and meet our energy goals. Furthermore, it improves economics of clean energy transitions while making utilities more resilient against market volatility and fuel price fluctuations.
Environmentalism can help families avoid high energy bills and save on health care expenses associated with pollution.
Buildings
Energy efficiency in buildings encompasses a diverse array of strategies, technologies, and practices for reducing total building energy consumption through better design, construction, intelligent operation and integration with sophisticated electric utility grids. This practice encompasses heating, ventilation and air conditioning (HVAC), lighting systems (including LED lamps), major appliances such as washer/driers/fridge/freezers etc, as well as energy consumption within all its subsystems such as heating/ventilation/air conditioning (HVAC/AC) units/subsystems/etc.
Energy efficiency measures include continuous insulation, airtight ducts and windows, LED lights and smart thermostats – which are among the most cost-effective strategies to reduce energy use and save money.
Energy efficient buildings provide long-term advantages that include reduced water, energy, and maintenance costs; reduced greenhouse gas emissions; less environmental impact due to renewable and clean energy use; enhanced thermal comfort for occupants which in turn can increase employee productivity and morale while benefitting the overall health of a business; additionally mortgage lenders are offering higher value and reduced risk loans on properties meeting certain energy efficiency standards such as ENERGY STAR certification;
Transportation
Transportation provides access to goods and services, transports people around the globe, and trades over $18 trillion worth of products annually. As an integral component of global economy, yet also having significant climate ramifications; GHG emissions incurred due to transportation are responsible for 23% of worldwide greenhouse gas (GHG) emissions.
Energy efficiency is an integral component of an efficient transportation system, contributing to reduced fuel use and operating cost savings as well as reduced environmental impacts.
But energy efficiency alone cannot cut transportation-related GHGs and air pollution because consumers care more about a wide variety of attributes when selecting transport modes and vehicles – for instance, auto buyers may prefer SUVs over more fuel efficient sedans due to their increased size, power, utility, versatility, and durability.
Machines
Machines and equipment consume energy in the form of electrical current. Their energy usage depends on factors like their power rating (in watts or kilowatts) and duration of operation; these figures help determine their daily energy usage, which is expressed as Kilowatt-Hour (kWh).
Powering down machines during idle periods can be another effective way of reducing waste and wear-and-tear on equipment, while simultaneously saving on costs associated with waste removal and repairs. However, this practice must be approached carefully as it could impact production schedules as well as result in costly damage to machinery.
Electrical motors that are too large are wastefully increasing energy consumption, leading to unnecessary wastage of both resources and money. Correct dimensioning for machine tool needs reduces this wastage and saves both energy and money. With industrial manufacturing companies spending significant portions of their operating budget on energy consumption costs alone, energy efficiency measures are vital in mitigating these expenses while supporting corporate sustainability initiatives. Toyota management principles like eager reflection and continuous improvement (kaizen) may help identify opportunities for improving energy efficiency within factories.
Equipment
Energy efficiency in equipment is an integral component of a company’s sustainability initiatives and costs savings goals, and can reduce energy use when not in use. Energy efficient practices involve asking that equipment sleep or operate with minimal energy when not required, keeping up maintenance on it, purchasing efficient new machines that use less power, as well as monitoring usage trends over time via data collection methods such as installing an energy meter on machinery to monitor trends and identify optimization opportunities.
Over 40% of America’s energy usage goes toward operating appliances and building-related equipment, with federal efficiency standards, state regulations, and industry-sponsored campaigns such as ENERGY STAR helping reduce overall consumption.
One of the main obstacles to energy efficiency investments is funding. But effective value chain collaboration can unlock sources of off-balance sheet financing for energy efficiency projects, or businesses should use energy performance contracts as an alternative way of paying for their implementation over time.
