Everything you do up to information science doesn’t matter too much and differs wildly from person to person. What I want to talk about is how to progress after. I only have about ~40 hours so far so take my words with a grain of salt.

Solar Sails and Wind Turbines

I am conflicted about solar sails, It’s some nice power but there are two things, they don’t last forever, and don’t produce a lot of power. In my opinion, only use solar sails to power planets without wind power, because wind turbines are broken. A single wind turbine produces 300KW, which from my experience, with base production, is equivalent to 3 structure points, or plenty of solar sails, correct me if i’m wrong.

Wind turbines are also easy to produce, just iron and copper, for solar sails you need oil, and for structure points you need a ton of stuff. Just use wind turbines. Don’t deconstruct your solar sail production because you will need it for your dyson sphere.

Gravity Matrices

The gravity matrices aren’t too important at this stage in the game, and in my opinion, don’t waste your time building a massive factory just for green science. I’d say get enough for a single level of dyson sphere stress system, maybe more if you want some other techs. Later on there will be rare resources that make this much easier.
