[wvsyuwhe] Large finite remaining sources of energy

How many joules of energy will the sun emit over its remaining main sequence lifetime, if it could be collected with a Dyson sphere?

What is the Earth's remaining total geothermal energy (from radioactive decay)?

What is the rotational energy of the earth?

What is the gravitational potential energy of Jupiter in its orbit around the sun?  That is, how much energy could be extracted from Jupiter via gravitational slingshots, with the end result of crashing Jupiter into the sun?
