Earth is lagging.

The Kardashev's Scale measure a planet's technological ability to utilize the energy available to it.
A level 1 planet can use all the available energy of it home planet.
A level 2 planet can use all the available energy of its star. Think Dyson's Sphere.
And a level 3 planet has the ability to utilize all the energy of an entire galaxy.
Where is Earth?
We're level 0.7.
Still burning dead plants to heat water and spin a turbine.
We can do better.
