The Staggering Energy Cost of AI and Crypto

Modern computing infrastructure consumes more electricity than many countries — and the majority of that energy ends up as waste heat.

Of global electricity used by data centres by 2026 (IEA estimate)
150+ TWh
Annual energy consumption of Bitcoin mining alone
40–50%
Of data centre energy spent on cooling, not computing
~100%
Of electrical energy consumed by servers becomes heat

AI Training: A Power Hungry Process

Training a single large language model (like GPT-4 class) can consume 50–100 GWh of electricity — equivalent to powering 15,000 Australian homes for a year. Each GPU in a training cluster draws 300–700 watts continuously for weeks or months. Every watt consumed becomes heat that must be removed from the facility.

The International Energy Agency projects that data centre electricity demand will more than double by 2026, driven primarily by AI workloads. In Australia, this means billions of dollars in energy costs — and a growing share of national grid demand.

Bitcoin & Crypto: The Heat Factories

Bitcoin mining alone consumes more electricity than many countries — estimated at over 150 TWh annually. ASIC miners and GPU rigs run at maximum load 24/7, converting virtually 100% of their electrical input into heat. Traditional air-cooled mining facilities spend 30–40% of their total energy budget just on cooling infrastructure — fans, ducting, and air conditioning that generate no revenue.

In Australia's hot climate, this problem is even worse. Mining operations in western Sydney, Queensland, and regional areas face ambient temperatures that push air cooling to its limits for much of the year.

The Heat Problem in Numbers

Nearly half of every dollar spent powering a traditional data centre goes to cooling — not computing.

Server Power → Heat

Virtually 100% of electrical energy consumed by CPUs, GPUs, and memory is converted to heat through resistive losses. A 1 MW IT load produces 1 MW of heat that must be continuously removed.

Cooling Overhead

In a typical air-cooled facility (PUE 1.5), for every $1 spent on IT power, another $0.50 goes to cooling, power distribution, and lighting. At scale, this means hundreds of thousands of dollars per year spent moving air — not running workloads.

Wasted Heat Potential

Air-cooled data centres reject heat at 30–35°C — too low for practical reuse. Immersion cooling produces waste heat at 40–60°C, warm enough for district heating, industrial processes, or facility warming — turning a cost into a resource.

How Immersion Cooling Changes the Equation

By replacing air with liquid, immersion cooling slashes energy waste and transforms the environmental profile of compute infrastructure.

30–50% Less Cooling Energy

Immersion cooling typically achieves a PUE of 1.02–1.10, versus 1.3–1.6 for air cooling. That means 95–98% of your energy goes to actual computing, not moving air. For a 2 MW facility, this can save $300,000–$600,000+ per year in electricity alone.

There are no CRAC units, no raised floors, no server fans, no blanking panels, no hot/cold aisle containment. The entire mechanical cooling infrastructure that traditional data centres require simply doesn't exist in an immersion-cooled facility.

No Fans, No Ducting, No HVAC

Traditional data centres require massive ventilation systems — chillers, CRAH units, ducting, and precision air conditioning. These systems are expensive to install, maintain, and power. Immersion cooling eliminates all of them. Heat transfers directly from hardware to fluid to a simple heat exchanger.

The result: dramatically lower CAPEX on mechanical infrastructure, lower maintenance costs, and a cooling system that scales linearly with IT load rather than requiring oversized HVAC that runs at partial load.

Reduced Carbon Footprint

Lower energy consumption means fewer emissions. For facilities on grid power, a 30–50% reduction in cooling energy translates directly to a proportional reduction in scope 2 emissions. In Australia, where grid intensity is still significant, this matters.

Extended Hardware Life

Dielectric fluid protects components from dust, humidity, and thermal cycling — the three biggest causes of hardware degradation. Servers in immersion typically show reduced failure rates and 15–30% longer useful life, reducing e-waste generation at source.

Waste Heat Recovery

The warm fluid loop (40–60°C) enables practical heat reuse — facility heating, swimming pool warming, greenhouse heating, or industrial process heat. Turn your cooling bill into a sustainability asset or revenue opportunity.

The bottom line: Immersion cooling doesn't just save money — it fundamentally reduces the environmental impact of high-performance computing. Less energy wasted on cooling means less carbon emitted, less grid load, and more of your investment going to actual compute.

E-Waste Recycling Partnership

Sustainable computing doesn't end at energy efficiency. When hardware reaches end of life, it needs to be disposed of responsibly — not dumped in landfill.

Partnered with eWaste Recyclers Australia

We've partnered with eWaste Recyclers to provide our clients with end-to-end, large-scale e-waste recycling for data centre and industrial IT hardware. Dumping e-waste in landfill has been illegal in Australia since 2019 — and for good reason. Electronic waste contains hazardous materials that contaminate soil and groundwater, alongside valuable materials that can be recovered and reused.

Through this partnership, we offer a complete lifecycle solution: we help you cool your infrastructure efficiently with immersion cooling, extend hardware life, and when equipment finally reaches end of life, ensure it's recycled ethically and responsibly.
