That's because energy is a limited resource, and because we need it for all sorts of things. Basically, NOTHING AT ALL can be done without energy.

Because of air poulltion
scientists are concerned about conserving energy because one day our non renewable energy might get extinct and they need to think of another energy that might work.
Auguste Mouchout was the first man to patent a design for a motor running on solar energy.
In most cases people dislike running because it uses up all of your energy. Then if a random even happens, (for example, the evil chicken comes after you) you have no energy left to run away from it. And in many cases, people will die because of this.
Not anymore energy than your computer would use running any other big program. I'd only be concerned if it was running on an unplugged laptop, which would cause the battery to run out. The point of it is to put the energy and electricity your computer is already using by being on to good use.
Well you need enough energy to run and running gives you energy and good health
Solar energy is renewable. It will last for billions of years without running out.Oil is in danger of running out. Many people think that "peak-oil" time is past. It is becoming harder and more expensive to find and extract oil.
Yes. Though it is not designed to be so. Anything with electricity running through it is magnetic. People are more concerned with how strong is this magnetic field generated by the electricity running through it. Go read up on electro-magnetism.
no, it is kinetic energy.
The energy for running water in streams come from from heaven.
no,it was potential energy
