Stu I live in south central British Columbia, Canada.
It gets windy in my neck of the woods not to mention temperature extremes of 38C in the Summer down to - 38C in the Winter. Nothing like dragging out the well pump when it's - 25C (and snowing) with the ATV chained to a tree and using the ATV winch.
I did notice during that joyous event that, at the ambient temp. the pump felt hot. Geothermal heat pump anyone? In the next few weeks I'll be hiring a local excavator to do the ground work for my installation.
In my area diesel prices vary over the course of a year by about 5 %. Gas prices are much more volatile, with a price spread approaching 40 % and being higher than diesel about half the time. Prices in my area always rise magically during long weekends. It's very satisfying to be able to make biodiesel and be somewhat immune to all the price gouging.
