"The Hungarian city of Szeged now has the largest geothermal network in the EU."

"The thermal water, pumped up from a depth of 2000 meters and at a temperature of 90 degrees, is used to heat the water in boilers, which then circulates in Szeged's district heating network."

""We heat about half the city with geothermal energy, around 27,000 apartments," says Medgyes."

"The switch from gas to geothermal energy cost around CHF 70 million."

"The money came from the European Union and from a private investor."

"Experts estimate that around a quarter of the European population lives in areas that are suitable for such geothermal heating systems."
