The Dyson swarm is already under construction. There are any number of satellites with solar panels attached to provide power. Yes, technically they are in orbit around Earth, but Earth is in orbit around the sun, is it not?

But a solar-power-collecting Dyson swarm is still just an intermediate step (although one that might well be used for thousands of years). The ultimate power source is artificial fusion. This we have not achieved yet.

When we do, we will obtain the helium fuel required directly from the sun, magnetically pulling away the helium ions by the ton.

This will provide two huge benefits. First, we will have an inexhaustible supply of fuel for an unbelievable amount of energy and, second, the drain of helium from the sun will actually extend the life of our star significantly. We could add billions of years to the useful life of our sun.

That sound like win/win to me.
