Of course, increasing the energy of a star will hasten its eventual collapse/nova.

If every person on Earth were an Epic Wizard and cast Cold Magic Missile at the Sun (assuming Range = Sight), they'd kill themselves before they extinguished the Sun. If you were able to simultaneously release all of the energy contained in the Earth into the Sun, you would effectively accomplish nothing except your own demise.


Page number, please. 

OD&D, 1E and 2E challenged the player. 
3E challenged the character, not the player. 
Now 4E takes it a step further by challenging a GROUP OF PLAYERS to work together as a TEAM. 
That's why I love 4E.

For the record, the total energy contained in the Earth is about 5x10^41 joules.  The total energy output of the sun in a year is 1.2x10^34 joules.  This means that the amount of energy contained in the Earth is equal to the total output of the sun for about 44 million years.

Considering the sun has enough energy to run for another several billion years, the Earth is a drop in the bucket. 

But that drop would severely disrupt the thermal-gravitational balance of the Sun, which would be very, very bad.  You'd basically be able to convert that 5x10^41 joules directly into an explosion, since the sun is stable currently.  It's not quite up to the range of a supernova, which is 10^44 joules, but even one thousandth of a supernova would be vaporization for anyone in the solar system and quite possibly death for anyone in systems nearby.  "Nearby" in this case meaning within a hundred or so light years.

Hm, that's a lot higher than I'd thought our potential energy was

Depends on which potential energy you're talking about.  Gravitational potential with the sun, rotational energy, thermal energy, those are all much lower.

Instead, I went with direct mass-energy conversion, the whole e=mc^2 thing.  Which basically puts the rest of them down in rounding error due to not keeping accuracy out to nine significant digits.

But you did say "all of the energy contained within the earth" so, I stand by my decision.
