That's what American energy company We Energies warns about in Farm Energy News, which Hoard's Dairyman writes about. According to the energy company, the use of compressed air in robots is effective but not very energy efficient. A single robot requires a 6 kW (7.5 hp) compressor. Such a compressor requires as much power as a 16-stand milking parlor, according to We Energies. Also, a milking robot consumes twice as much hot water as a traditional parlor. To heat water efficiently, the company recommends placing milking robots close to the barn. A controller with variable frequency control can help reduce vacuum energy costs.
