Energy efficiency is the answer


Energy is important because increasing energy demand impacts price and security. Renewables will not replace fossil fuels in time to prevent environmental disaster, including pollution and climate change. These issues have tangible costs and need large efforts from all stakeholders. Doing more with less (Energy efficiency) is the answer and the quick solution for this issue.


Energy consumption and energy costs have been on the rise during the last 25 years. World energy consumption has risen 45% since 1980. It is predicted that by the year 2100, global energy consumption will reach 27.3 giga-tons. Emerging markets like China and India will soon be consuming more energy than developed nations such as the US and Western Europe.

These emerging markets account for more than 75% of new demand placing new pressures on global resources and aging infrastructure. This pressure will push up prices and create threats to the security of supply. While renewable energy supplies will increase, fossil fuel sources will grow even faster, and dependence on oil, gas and coal will still be strong.

On the other hand Carbon dioxide in the atmosphere has risen more than 33% since the industrial revolution and is now rising faster than ever before.

The energy dilemma requires us to meet a doubled demand for energy but with half of the greenhouse gas emissions, so Energy efficiency is the answer and Energy efficiency is the act of reducing consumption while achieving the same results.

Required actions:

To achieve energy efficiency and use it a profit center for our facilities we need a systematic approach usually called energy management system.

Energy efficiency is not a one-time project; it’s a continuous cycle. And that’s good, because it means we can approach the problem gradually and phase our actions according to our available budget.

You need to start from a firm foundation. Beginning with an energy audit allows you to prioritize your actions effectively. At the beginning simple data from the utility bill and some expert observations can discover a lot. If you have more detailed measurements available, that can increase confidence in the choices that you make. Temporary measurements may be enough to kick-start your program.

Generally, your energy audit will identify some low-hanging fruit in the area of passive energy efficiency. Fix the basics – like mending air/steam leaks, or insulating steam pipes. Passive energy efficiency would also include things such as high-efficiency motors, but those actions tend to require greater investments and cause more disruption when they are implemented. This may be hard to justify if the equipment to be replaced is relatively new.

When the equipment approaches end-of-life, analysis of the total cost of ownership can help support replacement with high-efficiency equipment.

72% of energy consumption comes from industry, residences and tertiary buildings. Energy efficiency is the cleanest and quickest solution to the energy dilemma. Cleanest because the greenest unit of energy is the energy you didn’t need to use. Quickest because with solutions that are available today, you can save up to 30%.
