Type 1.0 Civilization

A Type I.0 civilization is an advanced civilization that can control the resources or available solar energy of an entire planet. These resources are usually estimated to be around 10 petawatts, plus or minus one or two orders of magnitude. Humanity is close to becoming a Type 1.0 civilization at our current rate of development (some estimates say at least 200–250 years), but right now, using Sagan's logarithmic scale, we are somewhere around a Type 0.75 ± 0.01 civilization. It is expected that humanity will reach Type 1 by the year 2250.

Transportation

To unite the entire planet, a Type 1.0 civilization would need ways to travel between continents quickly, like airplanes or short-range spacecraft. While it might be possible for a Type 1.0 to go to other planets, they would still need technology to make those trips, like liquid rocket fuel or plasma. It's possible that these species may have some experimental form of near-light speed travel, but it would probably require too much energy or be too big to be practical.

Engineering

The engineering of a Type 1 civilization would have reached a point which would enable:

1. The terraforming of their own planet, moon, or other planets in their solar system.
2. The curing of many deadly and/or incurable diseases.
3. The capacity to move large amounts of materials and energy around between planets.
4. Entire continents of other planets to be given over to industrial production.
5. Manipulation of natural weather events.
6. The ability to feed every single member of their species (although this would most likely be the case when the species is closer to a Type II).
7. The creation of true AI (AGI).
8. The construction of space vessels in space, or of a space elevator.
9. The mining of asteroids, dwarf planets and other planetary bodies on a solar scale.
10. The capacity to permanently sustain all industries.
11. The construction of self-sustaining colonies.

Such a civilization would be incapable of:

1. Travelling between stars using FTL travel.
2. Construction of artificial moons, or of megastructures, (eg. Dyson Sphere)
3. Synthesis of antimatter on a large scale.
4. Manipulation of gravity.

Evolution

The immense scale of interstellar space might be what keeps civilizations from developing past Type 1.0. Even at the speed of light, traveling between stars to harvest material for a Dyson sphere would take years or decades, and would be difficult to overcome.

Military

The military of such a civilization would most likely be incredibly powerful. It would have affordable heat-based weapons, lasers, and coil guns that people could carry. It is likely that powerful energy sources could be far smaller than they are now, such as nuclear reactors being as small as a housecat. Most conflicts between planets could become very destructive. We don't know if nuclear weapons would still be used because if people could work together to achieve a Type 1 civilization, it's unlikely that they would have been used for a long time.
