well, it really is "extreme noobness"
At start, only make as much energy (solar/wind) as needed to run the factory. Anything more is basically wasting metal and time.
Do not walk around so long paths with commanders just to build some mexes. It means wasting his buildpower, use a conbot instead.
Later on, bad balancing of metal/energy by both players.
Hints:
-solars cost no energy to make. If you energy stall, make solars.
-reclaim rocks for metal (if you stall)
-Better to only build one big thing (geo, factory, guardian,..) at the same time. Cancel constructions if it allows to finish something else faster.
ExKGB's geo takes so long to finish because he makes a second (useless) factory at the same time.
-reclaim wrecks
-take all the metal spots you can get
-destroy all the enemy mex you can get
At very start, Zorch makes 6 lasertowers around his 3 startmexes, then more llt around the map - too many, especially so early.
Meanwhile his 5 mexes to the left are totally undefended and ExKGB could easily destroy them - one unit would be enough to destroy them! (eventually 2 mex get destroyed but late)
Basically no scouting at all.
ExKGB makes a guardian to counter Zorch's guardian but it is not even in range.
Zorch's guardian "controlls" the area around right geo but why did you not simply expand to the left geo? It was empty...
ExKGB:
For the bombers, the fusion would been a better target than the guardian. But you probally did not know enemy had a fusion because you never scouted his base
Bombing the guardian gained nothing, he reclaims the wreck and rebuilds it. Only bomb turrets if you want to attack this spot soon.
Only watched the oasis replay to 30min or so, might watch the other one later. But that might give you some ideas...
Maybe play online vs players that are better, you might loose but can learn from replay what they are doing different.
