That's not possible, but geothermal energy is a passive way of cooling that actually works (to some point). Install pipes sufficiently deep under the surface and drive air through them and soil will cool the air for you - and because its temperature is almost constant throughout the year you can both cool and heat the greenhouses and barns and even homes this way with very little extra energy (just electricity for fans to move the air, and even that can be reduced to work passive for heating as the hot air climbs up the pipes on its own)
