I was re-reading some of the other posts and there was a discussion going on about whether energy should always be taken cheap.
Intuitively, the increasing tech costs (which means that 50% cost means a lot less than 2x the tech level, more like 1 or 2 levels higher) combined with the square root effect makes energy cheap not terribly attractive. In most games, I research energy up to tech 4/10/16 at various moments, but hardly ever much higher. At energy normal this costs around 107090 (cumulative, not taking penalties for other tech into account), which at cheap would give level 19. This would give me sqrt(19/16)=1.089 or 9% less resources.
To get some numbers, I've put together a spreadsheet that calculates cumulative tech cost and compares where normal/expensive/expensive@3 stands compared to cheap for the same investment in energy tech. The graphs at the bottom give tech level equivalence and most importantly the resource hit per cheap tech level. Until around (cheap) tech level 10, growth is hit for normal and expensive, with a penalty of around 25% for normal and 40-50% for expensive. Normal settles at a ~10% resource hit, expensive around 20%. Taking expensive plus start at three ameliorates the slow start, starting more quickly than cheap for the first couple levels and never having much more than a 20% hit.

In the RW, taking energy normal instead of cheap yield 84 points, taking expensive@3 also yields 84 points, and expensive alone yields 144 points.
I'm assuming here a fairly default race, IFE+ISB+NAS, 1i 2 narrow 1 in 6, 15% growth, 1:1000, C+W cheap, P+El+B expensive.
84 points can buy you around 6 hab clicks (1:6 -> bad 1:4) or 1% growth and 1.5 hab clicks (1:5)
144 points can buy you 9 hab clicks (good 1:4) or 1% growth and 4 hab clicks (1:5) or 2% growth and 1? hab click.
(144 plus 3 hab clicks (1
