Userful is the Green Solution:
Reduce CO2 Emissions and Electronic Waste

Userful reduces CO2 emissions and electronic waste

Reduce CO2 emissions by up to 15 tons per year per system*

Reduce electronic waste by up to 80%

Userful's ability to turn 1 computer into 20 reduces electricity use by up to 90% as compared to traditional PC-per-workstation computing.

Reducing the number of computers in use has additional earth-friendly benefits. Electronic waste is an increasing problem globally due to the quick obsolescence of electronics. This is compounded by the fact that computer waste is high in many toxic materials such as heavy metals and flame-retardant plastics, which easily leach into ground water and bio-accumulate.

Reduce your electricity bill, hardware and support costs

Userful Desktop and Userful Multiplatform's ability to turn 1 computer into 20 saves you money by greatly reducing hardware and support costs. Multiplying your computers with Userful will significantly reduce your electricity bill, with even higher savings in an air-conditioned building.

Making a difference with green computing

Since 2002, Userful has saved its customers 793,609,574 kWh of electricity and prevented 615,047 tonnes of CO2 from being put into the air. That's equal to taking 106,409 cars off the road or planting 152,617 acres of trees.

Did you know?

Switching 1% of the world's PCs to Userful is equal to taking 26 million cars off the road.**
