Energy weapons - and energy ammo - are expensive. That unfortunately is the price of a high-tech weapon is a post-apocalyptic world. And the reason why 90% of wasteland inhabitants use normal Guns.
However, if you are primarily an energy weaopns character, then you can sell all the guns and bullets that you come across and buy every ounce of energy ammo available.
I haven't played post-patch (just come back from abroad) but pre-patch I found it a struggle to have enough microfusion cells, but there was plenty of small energy cells. With the plasma pistol damage upped to 33 (making it powerful even if you use weak "bulk" ammo), and the plasma defender ammo usage lowered from 3 to 2 per shot, it should be perfectly viable to play mostly using energy pistols, and pull out a microfusion-powered rifle for when the going gets tough.

The problem with this is that the energy weapons that are paying 2-3 caps for a shot don't do 2-3x more damage per shot when compared to their Guns counterparts.
