What Does Being Energy Efficient Mean?

When we talk about energy efficiency, we’re referring to the ratio of power consumed to output produced. This holds true for any system that uses power, whether it’s a hydroelectric dam lighting up an entire city or a grid connection providing electricity for a small business owner’s 3-D printer. No matter what you’re using energy for, you can almost always find ways to do more with less.

An inefficient system generates more carbon emissions than a system optimized for efficiency, so one of the first steps an organization should take to go green is to use its energy more efficiently. Increasing efficiency allows businesses to maintain the same production or service level while simultaneously reducing their carbon footprint.

Energy efficiency is also important for the financial health of an organization. Inefficient energy is really the same thing as wasted energy, and if you’re purchasing energy that isn’t directly increasing your productive output, you might as well be burning money.

Inefficient energy usage also puts more strain on your facilities and equipment, reducing their useful lifespan and driving up maintenance and replacement costs.

Why is Being Energy Efficient Important?

There are many good reasons to strive for greater energy efficiency. Let’s look at some of the most significant benefits it confers.

  • Minimizing harmful environmental impact. While a large part of the push toward going green and reducing carbon emissions involves transitioning from fossil fuels to renewable energy sources, increasing the efficiency of the energy you’re already using is one of the first and most effective things you can do to decarbonize.
  • Lowering operational costs. Energy inefficiency is wasted energy that serves no useful business purpose. Optimizing for efficiency ensures that you’re getting the maximum value out of your energy expenditures, which is more important than ever, given that energy costs keep rising.
  • Improving asset durability. Inefficient energy usage takes a toll on every business asset that consumes power. This is especially true for businesses that consume significant amounts of electricity on a large scale, such as telecom providers, data centers, and industrial facilities. Efficient energy usage reduces the wear and tear on these assets, lengthening their useful life and lowering the costs of maintaining them.

The benefits don’t end there—energy efficiency can also make your workplace safer and cleaner for your employees, improve your brand image and public reputation, and increase the market value of your commercial buildings.

How to Measure Energy Efficiency

Energy efficiency is not an abstraction. It can be calculated with accuracy, providing a performance indicator for measuring your progress toward goals.

To calculate the energy efficiency of any given system, you can make use of a simple formula:

(Energy Output / Energy Input) x 100 = % Efficiency

To follow this formula, you must first measure the energy going into the system using a standard unit such as watts or joules.

Then, you need to determine the productive output of the system using the same units of measurement.

Divide the energy output by the energy input, and you have an energy efficiency ratio. You can convert it into a percentage by multiplying it by 100.

For example, you might have a device that requires 600 watts of energy to produce 300 watts of productive output. 300/600 = 0.5, or 50% efficiency.

How to Calculate Solar Panel Efficiency

For organizations trying to become more sustainable, shifting from fossil fuels to renewable energy sources is critical. Solar power is one of the most accessible renewable sources, but even solar panels can have major variances in the efficiency of their energy output. To make the most of an investment in solar power, you have to be able to calculate the efficiency of your solar panels.

Solar panel efficiency is measured by determining how much natural sunlight the panels turn into usable energy. The average commercial solar panel can convert about 15% to 20% of the sunlight it receives. Efficiency is affected by the type of panel construction (monocrystalline panels are more efficient than polycrystalline and thin-film panels), the placement and orientation of the panels, and environmental factors like wind, rain, ice, snow, and UV damage from the sun itself.

You can calculate the efficiency of a solar panel by taking the power rating as expressed in kilowatts (which should be provided by the manufacturer) and dividing it by the panel’s surface area in square meters. Here’s the formula for calculating it as a percentage:

(Power Rating / Surface Area) x 100 = % Efficiency

Following this formula, the efficiency of a one-by-two-meter solar panel with a power rating of 400 would be 20%.
