Energy Efficiency and Operating Costs
Energy use is a major factor in sustainability assessments. Pneumatic actuators typically operate at around 10-15% overall efficiency due to energy loss in compressing and distributing air. In contrast, electric actuators can achieve 70-90% efficiency at the point of use.
This difference becomes significant over time. In high-duty applications with reliable air systems already in place, pneumatics may still be practical. However, where precision and energy conservation are priorities, electric actuators often offer greater efficiency.

Carbon Footprint and Emissions
Electric actuators generally produce fewer greenhouse gas emissions, particularly when paired with clean energy sources. In contrast, pneumatic systems rely on air compressors, which are typically powered by electricity but introduce energy losses and maintenance overhead.
| Actuator Type | Average Efficiency | Estimated Annual Energy Use (kWh) |
|---|---|---|
| Pneumatic | 10-15% | 250 - 400 |
| Electric | 70-90% | 80 - 150 |
Environmental Conditions and Clean Operation
Pneumatic actuators are naturally suited for hazardous or wet environments since they do not include electronic components. However, they often require air filtration systems and emit exhaust, which may include moisture or oil mist.
Electric actuators offer clean, quiet operation and do not require exhaust or compressed air. They are well-suited to cleanroom and indoor environments where air purity and noise are concerns.
End-of-Life and Recyclability
Pneumatic actuators are composed mainly of metal components and are generally easy to recycle. Electric actuators contain motors, circuit boards, and control electronics, which may complicate recycling efforts but also often have a longer service life in low-impact settings.
Final Thoughts: Choose What Works Best, Sustainably
Both pneumatic and electric actuators can support your sustainability goals depending on application, infrastructure, and performance requirements. Pneumatics offer rugged reliability in tough conditions, while electrics deliver energy efficiency and smart integration.
