Electrical energy is not actually an energy resource at all. Energy resources are materials you can find already there, ready to produce energy on earth. As my combined heating and power plants professor likes to say - "Can you drill for electricity?? I don't think so!"

However, most of the electricity produced today is made from non-renewable resources. These would include nuclear, natural gas, coal, and oil. All of these are gone once they are burned, without any way to get them back. Today, most of the electrical power industry has gone to natrual gas plants, simply because the time and effort required to get a permit for a coal or nuclear plant (15 years - never) far exceeds the (very cheap) cost of buying a pre-made natural gas plant and having the plant up and running, making money in 6 months.

There are renewable sources being used to make electricity. For instance, look at the hydroelectric plant at Niagara Falls. It powers most of Buffalo. Wind turbines and solar panels make up about 7% of the electricity produced in Pennsylvania. Iceland (or it may be Greenland - one of the two) is tapping into a natural geothermal steam system located under their island... the whole country runs on steam power - which produces hydrogen from ocean water and runs fuel cells (no pollution beyond water from fuel cells - very good energy!)

I hope this huge ramble is helpful!

That's a tricky one. The resources are things like fossil fuel, the sun, wind, coal, biomass, nuclear. Electrical energy comes from these resources. Maybe it's inexhaustible because we can always find something to generate it. But it would be the other two dependending on how the electrical energy is generated.

Electrical energy results from the movement of an electrical charge, and is commonly referred to as simply “electricity.” Ultimately, it has its origin in the electromagnetic force: one of the four fundamental forces of nature and the one that is responsible for the behavior of electrically charged objects. Electrical energy is the result of the interaction of subatomic particles with this force. Electricity manifests itself in natural phenomena such as lightning and is essential to life at a fundamental level. The ability of humans to generate, transmit and store electricity is crucial to modern industry, technology and, in most countries, domestic life.
The Origin of Electrical Energy

There are two types of electrical charge, called positive and negative. If two electrically charged objects are brought close to one another, they will experience a force. If the charges are the same — both positive or both negative — the force will act to push the objects away from one another. If they have different charges, they will attract one another. This repulsion or attraction is known as the electromagnetic force, and it can be harnessed to create a flow of electrical energy.
Using Electrical Energy

Electricity is useful both in itself and as a means of transferring energy over long distances. It is essential to various industrial processes, telecommunications and the Internet, computers, televisions and many other devices in common use. It can also be converted into other forms of energy for use in a variety of other applications.

When an electric current flows through a conductor, it generates a certain amount of heat. The amount generated depends on how well the material conducts electricity. A good conductor, such as copper, produces very little. For this reason, copper wires and cables are commonly used to transmit electricity: when heat is produced, energy is lost, so a good conductor minimizes energy loss. Materials that conduct electricity less well produce more heat, so they tend to be used in electric heaters, cookers and ovens, for example.

Electrical energy can also be converted into light. Early arc lights depended on an electrical discharge across a small gap to heat the air to the point where it glows — the same principle as lightning. Later, the filament light bulb was introduced: this relies on the current causing a thin, coiled wire to glow white-hot. Modern, energy-saving light bulbs pass a high voltage current through a thin gas, causing it to emit ultraviolet light, which strikes a fluorescent coating to produce visible light.

And last is most of the electricity produced is made from non-renewable resources.

Electrical energy is a storable source of energy. Its neither renewable nor any of those in your question.

Electricity is the flow of electrons in materials. A material that allows easy flow are good conductors such as metals. Gold is known to be the best conductor of electricity and is one of the reasons it is used in chip manufacture.

Electrical energy is not renewable. It is created by means of mechanical energy in some cases. it is like waves in sea. you cant be asking if wave energy is renewable because it is some thing that is always there. When you give energy to it, it shows up and when you dont give energy it is not there.
