Re: 2.

Abundance of energy is never gonna happen. Entropy is a bitch. Its always going to be a struggle.

The Sun is going to last a few billion years, we can worry about entropy later.

You are misunderstanding me if you jump to that specific little application of entropy. Entropy is like a thing every-time, including right now. It sort of guarantees us that there isn't much free potential energy laying around our planet.

The planet has a constant supply of an incredible amount of energy from the Sun.

Most forms of energy we can tap into can be traced back to the Sun, except for maybe nuclear.

Then try to use it! Its an uphill battle against the second law of thermodynamics. Thus no abundance, ever.
