How is energy conservation measured?

Question

Mila Bautista · Accepted Answer

Thermodynamically, Energy IS "conserved" - it only changes form. For environmental impact we compare the amount of energy that a process requires against different mechanisms.

For instance, I can calculate the amount of energy required to achieve the intended outcome if my primary process—which is currently in place and involves air conditioning with a closed-loop system—is air conditioning. My "energy conservation" would be the difference between the energy used with each system if I were to replace the compressor with a more energy-efficient motor, which would result in a lower energy usage for the same outcome. I can also set different goals for myself and decide to use only a fan to create a cooling effect rather than adjusting the temperature in the room. In this case, I will be conserving a lot more energy because running a single fan uses less energy than running the entire air conditioning system.

undefined Energy conservation is typically measured by comparing the amount of energy used before and after implementing conservation measures. This can involve tracking energy consumption through utility bills, conducting energy audits to identify areas of inefficiency, and monitoring energy usage with meters and sensors. Additionally, energy conservation can be quantified by calculating the reduction in energy consumption or the resulting cost savings achieved through implementing conservation measures.
