What do Pringle Creek Community and Bordeaux, France, have in common? We both are using geothermal technology to make more energy efficient homes. Geothermal energy works by using the constant temperature of the earth as a way to heat and cool homes more efficiently. How efficiently you may ask? During the hottest months of summer a couple of years back, a resident recollected on only paying about $40 per month to cool their home. Overall, whether heating or cooling our geothermal homes here at Pringle Creek, the cost relative to traditional methods is far less. Beyond living more sustainably through energy efficiency, we also have another thing in common with France, we have some great wine. In fact, there are over 500 wineries in the Willamette Valley. So, residents may enjoy a summer evening comfortably without fretting a high energy bill, and also savor a glass of locally produced Pinot Noir while watching the sunset. Who thought that wine and energy efficiency could be such a fine pair? Raise a glass to energy efficiency!

The city of Bordeaux, France, is planning to build a geothermal heating network to serve several of its neighborhoods.
French utility ENGIE won the contract to build the network through a competitive bidding process. According to ENGIE, its subsidiaries ENGIE Cofely and Storengy submitted the bid together. The concession was awarded for a 30-year period.
ENGIE said that Bordeaux Metropole Council has decided to explore a new geological horizon with the aim of finding a deeper and hotter resource – the first time this has happened in France, outside the Paris region, in 30 years.
The natural heat of deep aquifers will meet 82 percent of the neighborhoods’ heating needs, with the rest being supplied by natural gas, ENGIE said, adding that work on the heating network will begin once all the administrative permissions have been obtained. Drilling of the two geothermal boreholes, comprising a production well and a reinjection well, will start in early 2019 and last for four months.
According to ENGIE, the city will invest 43 million euros (US$46 million) in the heating project.
