Climate control improves the conditions from "Deadly" (0%), up through unpleasant, mild, good, and Optimal (100%)
I believe the effect may be per year, not per turn.
In order to terraform a world and change the atmosphere, you need level 7 or higher in planet utilization (same tech area as Climate control)
The atmosphere converters will instantly change the atmosphere to whatever the majority of colonists breathe after 3 years have passed.
Note that you cannot remove the atmosphere from a gas giant. Vaccuum breathers can never undome a gas giant, and will have to use captured population from other races instead...
Solar panels:
Each panel adds 50 to 150 supplies to your tanks for each star in the system.
While on the move, your engines will likely burn 60 supplies
per sector.
The net effect is a smaller loss of fuel.
Beware storms and black holes, since there are no stars in those systems, and your panels are useless.
Trinary systems on the other hand, can rapidly fill your tanks.
Organic Manipulation (Racial tech) provides some facilities to directly boost population growth.
For everybody else, try Urban Pacification centers, since happy people are productive people (in more ways than one
).
Troops on the planet will get you a happiness bonus as well.
Also, keep shifting populatino from your homeworlds and maxxed out colonies, so you don't waste any reproductive opportunities.
A third way to improve your numbers is through military means.
Capture:
- cargo transports
- colony ships
- enemy planets (with ground troops)
You can get billions of people in one go, so bring lots of transports for those planetary raids.
