Don't agree, sorry.
The vast majority of things in MineCraft are overly simplified. You're still doing roughly what is required for fusion (fusing two isotopes of hydrogen, in this case), and the power required to start the reaction is massive (50,000,000eu I believe).
Being able to produce hydrogen two from water is as close to accurate as we're going to get (see heavy water production else where for more data on that), and producing hydrogen three from hydrogen two is, again, as close as we're going to get this side of Eden.
Move that over to solar panels which seem to magically require such levels of technology I'm surprised we haven't had MineCraft's AdvancedSolar mod protested by environmental activists for our anti-green image. Then add generators which appear to somehow magically convert heat into energy (while possible, you aren't going to get much power out of it without a better transfer medium), and nuclear power (if you want to get started on illogical design) in general.
Yes, MineCraft is a simplification of the factors that contribute to it. You don't have to agree for that to be the case.
