Instead of converting everything to electricity...why can't we just use energy just the way they are?

Answer 1

Because your cell phone can't run on, say, the potential energy of water in a river. How would it work? But if you let the water fall down the side of a cliff, allowing nature to convert the potential energy to kinetic energy, and then have that water impinge on a water wheel, transferring the kinetic energy, the turning of the wheel can then power a generator which sends out the moving current that is the only form of energy our modern devices can utilize.

In times past, people were able to use energy in a form closer to the way it occurs in nature. The word "windmill," for example, describes the original purpose of such devices. The entire windmill was actually a mill. Inside the structure was a factory that depended on the turning of large mechanical devices in order to grind grain products or spin cloth. No electricity was generated. Modern windmills aren't mills at all, but we still use the term.

Answer 2

OK, electricity is the only form of energy we can transport? I would stay away from any future answers by Jazz, because he doesn't understand that natural gas can be transported as well as other forms of stored energy. I don't really have an answer, well, except that electricity may be the cheapest to produce and the most economical for users.

Answer 3

Electricity is the only form of energy which can be converted into any other form of energy easily and efficiently.This is why any energy we found naturally are converted into electricity which can be transported easily.

Answer 4

Suppose you place a piece of coal on a bulb and burn it. Will the bulb give light. Here also the energy from the coal is released in the form of heat but cannot be utilised by the bulb. Here the form of energy required is Electicity. Hence the available energy ( coal, Hydro, nuclear) is converted into a utilisable form.

Similarly in living organisms including Human beings, higher plant and animals, we know energy is obtained from glucose. But if you place a quantity of glucose on the surface of a cell, will it get the energy directly from glucose . No!. The energy entrapped in glucose is released by a process known as glycolysis and Kreb's cycle and the released chemical energy is converted into a form (ATP) that can be utilised by the cell for its growth and development.

Answer 5

Not real sure what you mean by 'energy just the way they are'.

But we use a lot of electrical energy because it's the easiest and safest to generate and transport.

Answer 6

Interestingly enough, most of our "energy" demands in practice are required for motion or electronics. However, we are still in the dark ages when it comes to both in that we only know how to utilize heat induced expansion to create motion.

Sure, we have maglevs and high energy particle accelerators, but these either are not practical yet (accelerators) or require electricity (maglev). We still only use the expansion of gas to "turn" things to generate motion (motion of motors, cars, electric turbines). Even nuclear energy only make use of the heat generated by the nuclear fission to generate steam ... pretty crude huh?

Other forms of electric generation are limited at present, either by technology or the practicality of implementation, but have potential (hydro, hydro thermal, solar, bio thermal, etc).

In short ... there's a lot of room for improvement, but it'll be a while!

Answer 7

Because electricity is the ony FORM that energy can be transported in!

Answer 8

mind energy is very useful source until..it is depleted

Answer 9

EASIEST WAY OF CONTROLLING POWER IS OFFERED BY ELECTRICITY THROUGH RESISTANCE/DIODE ETC. AND DIRECTION OF ROTATION CHANGES BY CHANGING WINDING CONNECTION .

Answer 10

you do it though selectively viz Sexual energy.
