What Is Energy Efficiency?
3 min read
How can we reduce energy consumption while maintaining an equivalent level of comfort or performance? This question is the driving force behind all initiatives.
What is energy efficiency?
In physics, energy efficiency means the of useful energy produced by a system to the total energy consumed to make it run.
But it also refers to efforts made to reduce the energy consumed by a system while maintaining its final performance at an equivalent level.
In other words: doing the same with less!
Example: Energy efficiency for a home means consuming less gas or but enjoying the same level of comfort. There are simple solutions out there: Double glazing and energy-saving light bulbs. These consume less gas or electricity while providing the same level of comfort.
Example: Energy efficiency for a motor vehicle means being able to cover the same distance while consuming less
.
Why is energy efficiency so important?
- Global demand for energy keeps growing strongly.
- It’s impossible to fully meet demand, even by building more plants.
- It’s diffcult to make up for the decline in fossil fuels (
, oil, gas).
So, we need to use energy better. So, we need to use less energy. That’s energy efficiency!
It’s especially vital in the manufacturing and building industries, which both consume a lot of energy.
Summary:
- Energy efficiency = efforts made to reduce the energy consumed by a system while still maintaining its final performance at an equivalent level.
- At home = consuming less energy while enjoying the same level of comfort.
- Optimizing energy efficiency in buildings and manufacturing is essential to reduce consumption and meet increasing demand.
