Definitely - in the context of heat pumps. Norway has no geothermal heat that can be used directly (the way the do in Iceland).

The "problem" is that heat pumps for geothermal energy are high quality, durable ... and at least 4-5 times as large investment for the heat pump alone as for the air-to-air heatpumps. And then you must drill a well, usually around 500 ft deep. As long as you built your house on rock, it isn't too expensive, but if it is build on sand, you cannot just drill, you must brace the hole to keep it from collapsing, which raises the cost significantly.

If you make the investment, your heatpump will have the same efficiency year round. An air-to-air heat pump doesn't give you much energy "for free" when it is -20F (or -30C) outdoors, when you need the heating the most. As you point out: Summertime, you can use the well for cooling (the Icelanders cannot do that!), and that is another significant reason why people choose a ground heat variant, rather than air-to-air.

Under my house, I would have to drill at least 150 ft, maybe more, before reaching solid rock. But I will remodel my garden, raising the level of the lawn by almost 4 ft. So I scrape off the old top soil, lay out a zig-zagging cooling pipe of 1200 ft length, fill 4 ft of soil on top and put the topsoil back. This moving of soil would have been done in any case, so the extra cost is limited to the cooling pipe (and a little work).

Another option used by some people is to throw the cooling pipe out in the river, into the bay or into a lake. But then it should be anchored well, weighed down, and lay so deep that water won't freeze around it. And you should make very sure that no boat is throwing out their anchor where you locate it.
