It depends on the context.
The Conservation of Energy is a physical law.
Conserving energy is an act we perform to save money and help the environment.
The 1st Law of thermodynamics is a restatement of the law of conservation of energy.

This is from wikipedia: (Note the bit in italics)The law of conservation of energy is an empirical law of physics. It states that the total amount of energy in an isolated system remains constant over time (is said to be conservedover time). A consequence of this law is that energy can neither be created nor destroyed, it can only be transformed from one state to another. The only thing that can happen to energy in aclosed system is that it can change form, for instance chemical energy can become kinetic energy.
By the first law of thermodynamics, energy is conserved - i.e. the sum of the useful work and the energy lost to heat will equal the energy you started with. The second law states that you will never get 100% energy efficiency.
There is no such thing - energy is ALWAYS conserved.

None. E=Mc^2 simply extends conservation of mass to conservation of mass-energy by demonstrating that mass and energy are only different forms of the same thing. Although neither mass nor energy is conserved by itself together the total mass-energy is always conserved.
There is no such thing. "Artificial" means made by humans; humans can't really MAKE energy. They can only harness EXISTING energy sources.For more information, I suggest you do some reading on "Conservation of energy", for example in the Wikipedia.
It doesn't really have to - there is no such thing as "mass-to-energy conversion", rather, a change in energy will be accompanied by a change in mass. But the change in mass sometimes simplifies calculations.
The factory owners manual calls for 10W/40 ( I run 20W/50 in the summertime in Calif.). The only thing you have to make sure of is that the starburst symbol on the container does not say anything about energy conserving. 10W/40 on up will not be energy conserving.

It is where if nothing is let in or let out of a substance the mass will not change. For example, if you had a bottle with a substance in it and nothing passed in or out of that bottle, the mass would be the same no matter if a chemical reaction occurred inside the bottle. This makes sense, since mass is made up of atoms, and if the amount of atoms is the same then the mass won't change.
There are a few options to be considered when a country is facing an energy crisis. The first thing to be done is to analyze the excess or wasted use of energy and reduce it as much as possible. Importing energy sources may be required. Also, developing renewable energy solutions and informing citizens about energy conservation.
