On July 24, 1847, a wagon train of pioneers arrived in the valley of the Great Salt Lake. From the back of his wagon, the Mormon leader Brigham Young, who was ill with mountain fever, looked out at the vast desert below and declared, "This is the right place" The current inhabitants of Salt Lake City still believe their city is the right place; they are

proud of their handsome city and welcome visitors from around the world to enjoy its famous hospitality. There is still a pioneering spirit to make their desert blossom and they have turned to renewable energy to achieve this. Just over a year ago, Salt Lake City Mayor Jackie Biskupski (who is slated to speak at the Opening Session of the GRC Annual Meeting), announced an initiative to transition the community to 100% renewable energy sources by 2032 and to reduce carbon emissions citywide by 80% by 2040.

The geothermal community can certainly help Salt Lake City realize this goal. At present, three geothermal developers; Cyrq Energy, ENEL Greenpower and PacifiCorp produce 73 MW of geothermal electricity, but this is only a small percentage of the estimated 1300 MW of untapped potential in the state, enough to power a third of Utah. However, that’s only part of Utah’s geothermal story.

Utah has a long history of utilizing direct resources for space heating, growing tropical fish and recreation. Geothermal water is used to heat more than 25 acres of greenhouses in Newcastle, one of the largest greenhouse complexes in the U.S., and 330,000 sq ft of prison space. Spas and hot springs provide opportunities to dive and swim in the thermal waters. In Grantsville, 40 miles west of Salt Lake City, the adventuresome can swim with salt water fish. Elsewhere, geothermal heat pumps are gaining ground with large scale installations used to heat and cool school and church buildings. Geothermal is making the Utah desert bloom.

This year's GRC Annual Meeting & GEA GeoExpo+ offers a tremendous opportunity to learn about new advances in geothermal

energy and to rekindle relationships with geothermal colleagues. More than 270 papers have been submitted for oral and poster presentations, a number we have not seen in a decade. Papers highlighting geothermal developments and investigations in more than 30 countries will be presented.

This event remains the biggest in the geothermal energy calendar. For over 40 years it has provided an opportunity for the global community to come together to share and learn. Participants will have opportunities to visit geothermal power plants in central Utah and the geothermal wonderland of Yellowstone National Park on GRC Fieldtrips. On Friday and Saturday prior to the start of three full days of technical sessions, meeting attendees can participate in workshops on Geothermal Resource Decisions and Operations & Maintenance. The Geothermal Energy Association (GEA) will host over 70 exhibitors at the GeoExpo+ and also joint sessions on business and policy. The Opening Session of the meeting on Monday morning will feature stimulating discussions on current geothermal energy topics. An International lunch and session will provide the latest updates from abroad. The social highlight will be ‘a Night at the Museum’ - a fun networking event at the superb Natural History Museum of Utah perched in the foothills above Salt Lake City.

For a full listing of the activities at the GRC Annual Meeting & GEA GeoExpo+, I recommend going to the GRC website at https://geothermal.org/meet-new.html for the latest information. There you will find an Event Program you can download. Better still, download the Event App to your mobile device for easy access to everything you need to know (see page 2 for information on the Event App). For those not attending the technical sessions, or are new to Salt Lake City, a list of tours and sightseeing opportunities in the Salt Lake area can be found on the website. If you have a few extra days, consider renting a car and touring some of the national and state parks in Utah and in the surrounding states.
