The lobbying group's board of directors elected Groebler to replace RES CEO Ivor Catto. He will serve an 18-month term.
Groebler said continuing to increase the scale of wind power was the industry’s main challenge.
"The next challenge that we face as an industry is to continue ramping up scale as Europe phases out fossil fuels and electrifies its economy. Wind energy is ideally poised to become Europe’s future electricity producer of choice," he said.
Groebler studied mechanical engineering, and has served several roles with Vattenfall since 1999, now leading the energy company’s wind, solar and battery division.
WindEurope CEO Giles Dickson said: "Having one of the world’s biggest renewable energy companies at the helm of WindEurope, with its expertise in wind will certainly be a great asset to us."
Dickson added that Catto had been "instrumental" in WindEurope’s efforts to make the economic case for wind energy.
