The Earth maintains ~300K receiving 2e17 W from the Sun. If the earth
generates and uses 100 * 2e22 W locally, that's 1E7 times as much,
raising the Earth to ~17000K on a T^4 basis.

The Earth should use Solar power, not compete with it.

Presumably by the year 2667 planets will be zoned residential only - the
heavy duty stuff will occur out where no-one will be inconvenienced.

BTW I recall a suggestion for moving planets (by a Brit if I remember
correctly) by equipping asteroids with fusion moters and making multiple
gravitational slingshots - with the difference that the planet would slowly
gain energy from the slingshots.
