Why Energy Efficiency Is Becoming the Real Currency

As global power demand surges from AI and renewables reshape the grid, businesses must turn to energy efficiency to cut costs, reduce risk, and stay resilient.

For the first time in history, renewables have overtaken coal as the world’s largest source of electricity, making up 34.3% of global power generation in the first half of 2025. (The Guardian) Wind and solar are leading the charge, but the global energy landscape is entering a new and more complex era — one defined not just by how we produce power, but by how much we use.


And lately, usage is spiking.


The AI Boom Is Rewriting the Energy Equation

From data centers to chip foundries, the AI boom has ignited a new kind of industrial revolution. Major tech firms (such as Nvidia, Microsoft and others) are no longer waiting for the U.S. grid to catch up; they’re building their own power plants. In fact, one analysis finds that electricity costs in some regions near large AI data centre installations have surged up to 267% compared with five years ago. (Bloomberg)

It’s not just abstract. In the U.S., wholesale electricity prices that would have been modest in 2020 are now far higher in data-centre hotspots. (Sandbox)


Why is this relevant?

  • These high-demand loads strain the grid, making the cost of electricity (and grid services) higher for everyone.

  • The more power-hungry the infrastructure becomes, the greater the business risk for enterprises that rely on stable, affordable energy.

  • As grid infrastructure lags behind demand, companies and organizations have to ask: What control do we have over our energy consumption?


When Power Becomes a Premium

Every kilowatt-hour now carries more weight, especially for companies operating large buildings or complex HVAC systems (sound familiar?). Efficiency isn’t just an ESG metric anymore; it’s a business imperative tied directly to cost-control and resilience.

We’re now at a moment where:

  • Renewables are expanding fast, but demand is rising even faster in some tech/industrial sectors. For example, the International Energy Agency (IEA) projects that electricity demand from data centres will more than double by 2030 to around 945 TWh — “more than four times faster than the growth of total electricity consumption from all other sectors”. (IEA)

  • Some regions are seeing localized shortages, transmission constraints and higher wholesale power prices. In the U.S., wholesale electricity prices in several markets were up by 40-80 % in 2025 compared with 2024. (Construction Physics)

  • Organizations that wait for the “grid fix” may find themselves paying a premium (or exposed to reliability risk) in the meantime.


Put simply: If you can’t fully control your energy supply, you must control your energy use. Efficiency becomes the operational hedge.


The Efficiency Imperative

Here’s where the story turns from macro trends into actionable insight. The good news: The same technologies driving smarter AI are also enabling smarter buildings and systems. Intelligent filtration, automation, low-pressure HVAC systems, demand-response strategies — these are the tools to control the energy side of the business.


Here are three reasons why now is the time to focus on performance and efficiency:

  1. Cost Avoidance Becomes Value Creation

    With energy prices under pressure and demand growth uncertain, reducing consumption becomes a direct cost-mitigation strategy.– Efficiency improvements often pay back faster when baseline energy costs are rising.


  2. Grid Risk = Business Risk

    Relying solely on external supply (even if green) is a vulnerability; the more you rely on the grid, the more you’re exposed to spikes, shortages or regulatory premium pricing.– Being energy-efficient gives you more independence and control.


  3. Sustainability Meets Differentiation

    With the global pivot to renewables (for example, the projection that global renewable capacity additions between 2025-2030 will be ~4,600 GW) IEA — the organisations that get ahead now won’t just be “green” — they’ll be efficient green. That matters for brand, operations, risk profile.


When you think about building automation, indoor air quality and HVAC systems, you’re often dealing with the largest energy loads after lighting in a built environment. By focusing on filtration, optimization and smart control, you’re reducing both the peak load and the total energy used, which in the current climate is exactly the kind of strategic leverage organizations need.


  • Yes: the news about renewables overtaking coal is encouraging — that shift shows progress. But it also hides a key truth: demand is increasing fast, thanks in part to data, AI, buildings and more.

  • That means supply-side improvements alone aren’t enough. They must be matched by demand-side discipline (i.e., efficiency).

  • Organizations that act now to optimize their energy consumption will be better positioned, from cost, risk and sustainability standpoints, in the years ahead.


So whether you’re managing a campus, commercial building or industrial facility: don’t wait for the grid to “catch up.” Focus on what you control. Because in this new power era, efficiency is the real currency.

The CADR rating is essential in determining an air purifier’s effectiveness and helps consumers compare the performance of models and brands, making it easier to find an air purifier that will meet their needs.

With the growing concern over indoor air pollution, air purifiers have become an increasingly popular appliance in many homes. However, with so many options on the market, choosing the right air purifier can take time and effort. In addition, consumers are often faced with various specifications, features, and marketing claims, making it difficult to compare different models and determine the best fit for their needs. One key factor that can help differentiate air purifiers and make the decision-making process easier is understanding the Clean Air Delivery Rate (CADR) rating.


This blog will explore CADR and how it can help you choose the right air purifier for your indoor space.


What is CADR

Clean Air Delivery Rate, or CADR, is a widely recognized benchmark established by the Association of Home Appliance Manufacturers (AHAM) in the United States. This independent organization certifies and verifies the performance of air purifiers through CADR testing, ensuring that the manufacturer’s claims are accurate. This makes it easier for consumers to identify which air purifiers are the most effective in removing indoor air pollutants like dust, pollen, and smoke.

CADR evaluates the performance of an air purifier based on the amount of clean air it produces per minute and the size of the room it is intended to be used in.


CADR Certification

Air purifiers with an AHAM-verified CADR rating are tested using a standardized method. According to AHAM, a CADR figure is tested through a standardized method in a test chamber with a volume of 1,008 cubic feet. As the tested air purifier runs at full speed, the amount of dust, pollen, and smoke contaminants is continuously monitored. The air purifier’s CADR rating is calculated based on how long a unit takes to purify the air.


Understanding Why CADR for Air Purifiers is Important

The CADR rating is essential in determining an air purifier’s effectiveness. It helps consumers compare the performance of different models and brands, making it easier to find an air purifier that will meet their specific needs. For example, air purifiers with higher CADR ratings will be able to clean the air in a space more quickly than models with a lower CADR rating.


‘The higher the CADR, the better the performance.’


In addition to a CADR rating, here is a short list of the areas we recommend you consider when buying an air purifier:

  1. Filter efficiency, size and amount of filter media

  2. Noise level

  3. Motor quality

  4. No ozone

  5. Square Foot Area coverage
