Second Law of Thermodynamics

The second law of thermodynamics is like a toy wind-up car. You wind it up, adding energy to the car, and then it goes for while before running down. So you wind it up again and it goes some more.In the same way, life on earth would quickly run down if not for the sun continually winding it up with new energy. If the sun were to go out, most life on earth would die.The sun won't shine forever. It is radiating its energy off into space, of which we receive a small portion, and eventually it will run out of energy and shine no more, consistent with the physical laws of the universe which of course include the second law of thermodynamics.--Percy

There's nothing special about earth. Mark only meant that planets receive energy from the suns they orbit. They also reradiate energy out into space. As Jazzns implied, they probably radiate some of their own energy off into space, too, which means they're gradually losing net energy and cooling.An entropy budget for an entire planet isn't realistic (entropy is more than just a matter of gaining and losing energy), but it isn't what you want for this issue. What we're really interested in is the biosphere where life lives, not the whole planet. Life absorbs energy from the sun and locks this energy into chemical bonds through photosynthesis for use in growing and reproducing. Growing plants are definitely experiencing decreasing entropy.We can't imagine what life might be like on other planets, but if it exists then it does so through the same process of absorbing energy from a nearby star to fuel life's processes.Is the earth experiencing a net gain or loss of entropy in the biosphere? Who knows? That's an incredibly complex question. Probably it's not too far from equilibrium, though our burning of fossil fuels might have some influence.The important point is that life is just chemistry. Extremely complicated organic chemistry, but still just chemistry. Reproductive errors are the source of much variation, and they, too, are just chemistry. And living organisms and plants and animals living their lives and succeeding to reproduce or not is just more chemistry. Evolution is just chemistry, and chemistry does not violate 2LOT.--Percy

This would be incorrect. First, transforming energy into electrical form is not necessary to do work. Second, many natural processes produce local reductions in entropy. For example, when the sun's energy drives a chemical reaction that results in energy being stored in chemical bonds, a local reduction in entropy occurs. Your terminology is very non-standard and probably open to misinterpretation. Entropy is not a product of a process but a quality or attribute of a system. Just as you would never say that a growing plant is producing size, you wouldn't say that an active process is producing entropy. You would instead say that growing plants increase in size and that active processes increase in entropy.--Percy
