Hi,
I usually tend to use generators for quite a while once I start a new world, at least
till I can afford a pump and two to three thermal generators and some windmills. I don't
really like being depend on one energy source for longer then neccesary, hence building
two.
Once I gathered enough resources, I build usually an electrolyzer, a few centrifuges and
a few diesel generators and gas turbines and supply both with whatever excess I have.
Once I get around having a magic energy converter, I try to rid myself on all the mercury
having gathered up in the mean time, making a nice energy boost.
One chamber reactors are also a favorite as soon as I can afford them, 100 eu/tick extra
for a few uranium do not hurt.
Then I usually go about switching my centrifuges to run off steam instead of main power and
try go get a decent wind power park up as well. If I have the resources that around the time
I try to get some biofuel going for the diesels as well.
once that's all set I focus on some lightning rods and maybe a dragon egg syphon (if affordable)
to power things.
