Energy Efficiency in the Laser Marketplace

The record energy efficiency of IPG fiber lasers is enabling a transformation within the laser industry similar to the electric lighting industry. Over the years, advances in lighting and laser technology have improved the energy efficiency of these products and lowered the total cost of ownership.

Nd:YAG (Lamp Pumped) = Incandescent

Electrical Efficiency: 2%

 

Nd:YAG laser wall-plug efficiency is about 2%, which is equivalent to a traditional filament bulb. The majority of input energy is lost as heat. In a laser setting, this means that more electricity is needed to get required output power, necessitating powerful chillers to dissipate the significant heat which is effectively lost energy.

 CO2 = Fluorescent

Electrical Efficiency: 7 to 8%*

 

CO2 lasers are 3-5x more efficient than Nd:YAG lasers. More than 90% of input energy is lost to heat, much like a CFL light bulb. Significant cooling is still required for most industrial applications, further increasing energy usage.

* includes chiller

Fiber = LED

Electrical Efficiency: 45 to 50%

 

IPG’s fiber lasers have efficiencies from 45–50+%, dramatically reducing the input power needed. In addition, fiber's high surface area to volume ratio combined with its efficiency significantly reduces heat output and the corresponding cooling cost of a chiller.

 

Did you know...?

  • We estimate electricity savings from operating IPG fiber lasers instead of other lasers enabling 28 billion pounds less global CO2 emission since 2011 and 10 billion pounds less CO2 emission in 2018 alone. To put this savings into perspective, 28 billion pounds of CO2 emission approximates the annual output of six 500 megawatt coal-fired electric plants.
  • The 2016 reduction in CO2 emissions from all IPG lasers sold over the last three years is equivalent to Vermont's yearly CO2 emissions.

Environmental & Safety Initiatives

 

  • IPG operations are compliant with the Restriction of Hazardous Substances (RoHS), Waste Electrical and Electronic Equipment (WEEE) directives as well as the Toxic Substances Control Act (TSCA)
  • Since 2006, a cogeneration plant has been operating in Oxford, reducing emissions by using waste heat from power generation to heat and cool buildings, saving more than 1.1 tons of greenhouse gases yearly.
  • In 2015, a second 1 MW generator was installed and reduces greenhouse gas emissions by an additional 5 tons yearly, and a 3 MW generator is was installed in 2017.
  • All new construction is built at a higher level than energy code requirements.
  • IPG has implemented a metal recycling program which saves thousands of pounds of aluminum, copper, and steel annually.
  • From 2010 to 2016, machine shop recycled metal grew 34 times to 306 thousand pounds.

Committed to Conflict-free Sourcing

  • IPG is committed to legal compliance with the Dodd-Frank Wall Street Reform Act, including the due diligence requirements relating to the responsible sourcing of tin, tantalum, tungsten, and gold (3TG).
  • Our team works diligently towards obtaining disclosures from its suppliers concerning whether any of IPG's 3TG originates from conflict regions or funds conflict there.
  • We require all suppliers to comply with legal requirements relating to responsible sourcing.
  • If any of our suppliers cannot demonstrate sufficient compliance with their due diligence and disclosure obligations, IPG will seek alternative sources of these 3TG metals.
