Radars do consume a lot of energy at the beginning of a game, but even just one placed early and running continuously will find the ore needed to produce exponentially more power. After that, I no longer think about radar power consumption. I just place them willy-nilly wherever they'll be useful. They're even spaced throughout my factory's interior just so I can see it working on the map from anywhere.
