The ten domains of
energy management.

Walk through each domain step by step. See where energy enters, how it transforms, and why management ties everything together.

Step 1

Energy Harvesting

Energy is everywhere around us — in light, vibration, heat gradients, and radio waves. Harvesting captures this ambient energy and converts it to electricity. The challenge: ambient sources produce microwatts to milliwatts. A smartphone needs watts. The gap is three orders of magnitude.

Power Scale
1 µW
RF harvester (ambient WiFi)
100 µW
Indoor solar cell (10 cm²)
10 mW
Outdoor solar cell (10 cm²)
50 mW
Enough for a low-power MCU (always on)
5 W
Smartphone (continuous use)

The key insight: harvesting doesn't replace generation. It eliminates the need for it in devices that can run on milliwatts.

Step 2

Energy Generation

Solar hit $0.02/kWh. Wind is close behind. Nuclear is going modular. For the first time in human history, generation is approaching abundance. This is the one domain we're actually winning at.

Cost Per kWh (2024)
$0.02
Solar
$0.03
Wind
$0.07
Nuclear
$0.10
Natural Gas

Cheap generation shifts the economics from “produce less” to “waste less.” Management becomes the bottleneck, not physics.

Step 3

Energy Conversion

Every time energy changes form, some fraction becomes heat. A data center power path has 6–8 conversion stages. Each is 90–95% efficient. Chained together: only 60–70% of the energy reaches the chip.

Conversion Cascade
Solar DC → 95% Grid AC → 94% Building AC → 92% PSU DC → 96% VRM DC → 90% Chip
Total efficiency:
67.4%
— one third is heat
Step 4

Energy Conditioning

Raw power is noisy. Voltage sags, harmonics, transients. UPS systems waste 4–10% of throughput in standby. Intelligent conditioning adapts to the load — if the source is already clean, skip the heavy filtering.

Step 5

Energy Distribution

The US grid loses 200 TWh per year in transmission. The shortest distribution path is no path at all. On-site solar plus battery eliminates transmission losses entirely.

Step 6

Energy Storage

Storage is a time-shifting tool. Charge when energy is cheapest, discharge when demand peaks. A well-managed battery system turns intermittent renewables into reliable baseload.

Try it: Battery Simulator

FERRIX can simulate battery electrochemistry — the same solver engine used for plasma transport, applied to lithium-ion cells (NMC and LFP chemistries).

Step 7

Energy Measurement

You can't manage what you can't measure. Most facilities know their total power bill. Few know consumption per workload. The FERRIX simulator reports every simulation's energy cost in millijoules — measurement built into the tool itself.

Step 8

Energy Management

This is the missing piece. Nine domains work in isolation. Management is the intelligence layer that sees all of them and makes real-time decisions: shift load here, discharge battery there, skip this conversion, recover that heat.

Without management
39.5%
facility energy efficiency
With management
87.9%
same facility, same hardware
Step 9

Energy Recovery

A data center is a space heater. All electricity becomes heat. Most facilities spend additional energy to remove it. Nordic data centers already pipe waste heat to warm homes. The technology exists. What's missing is the management layer that routes heat to where it has value.

Step 10

Energy Renewal

Batteries degrade. Panels lose efficiency. Transformers age. A battery managed well lasts 2–3x longer. Predictive maintenance and lifecycle-aware scheduling turn renewal from a cost center into a competitive advantage.
