The majority of electricity currently used is generated by large power stations. However, exhaust heat that goes unused when generating electricity and energy lost when transmitting electricity decreases overall energy efficiency down to around 40%. In other words, approximately 60% of the energy generated goes to waste.
Yanmar has developed a cogeneration system with the aim of achieving a society capable of efficiently utilizing energy without waste. Our system produces energy through engines powered by fuels that have a low environmental impact such as carbon-neutral biogas and natural gas. The heat produced during power generation is effectively utilized in the hot-water supply and heating and cooling to reduce energy loss. Yanmar has realized utilization of both electricity and heat through industry-leading efficiency.
