Use of electricy in factories, industrie and pructibe use of it?

  1. Aug 1, 2010 #1
    How important is electricty in our modern society and in the process of making the things we use?. Do they used in chemical industrie? How much is used in hospitals? Is electricty vital?

    it is vital to certain industries, like refining aluminum ore. but the primary advantage to electricity is that it allows you to centralize a potentially-polluting source of energy (combustion of coal). then, you can better scrub pollutants from the exhaust, and dispose of it in a more controlled manner.

    if you like clean air, it's a good way to go.

    edit: oh, and if you like electronics, then you're pretty much stuck with creating electricity somewhere. ;)

    In my opinion, electricity is vital to modern society; as we live it, that is.

    I so enjoy camping without any standard electricity service.
    Not sure how much I would enjoy it if prolonged!

    Im thinking in electrical engineering. I just dont wana end in a pointless job or feel that i dont contribuet to society. So im looking for career path in science that have benefits to the quality of life.

    that is more of a philosophical question. civil/sanitation engineering has probably done more to promote quality of life than most things by providing us with clean drinking water and safe waste treatment. but you may or may not feel like it is a fulfilling career.

    What about telecommunications, refrigeratos that help us maintain our food. What about the electricy used in factories? I dont want to start a thing like EE vs Other engineering or Science, but doesent electrcity make our lives better or it just make it more complicated and less fulfilling?. Talking about philosophy i was thinking in study it after my retirement xD.

    refrigeration is a huge benefit to society, but it's more about mechanical engineering. factories are also awesome by giving us great material wealth at low price, but if you live in somewhere like america, you've probably seen most of the factories move overseas where labor is cheaper.

    honestly though, i think most things science-based contribute to society. stay away from gambling and drugs as enterprises and you should be good. pick something you enjoy, but also pick something that has a future for you. if you can't find or keep a job in your chosen career, or spend all your time working, you aren't likely to be fulfilled.

    beware, though. most engineers spend life in a cubicle. i hated it.

    :yuck:
    Camping...? :yuck: :yuck:
    I have a very firm policy that I will never go anyplace where the bugs outnumber the bathrooms.

    Well in overall im thinking in a science career. Thanks for the advices =)

    Any one have more ideas of the usefullness of electrcity? Would society be worst without it?

    No electricity = No internet porn.:biggrin:

    Perish forbid! Whatever would I do with myself?

    Imagination is better =(. Thanks for making me feel bad.

    Imagination is better, there goes sarcasm to say "hey electrcity sucks" =(

    I'm an electric engineer myself and electricity is very important, but any kind of enginnering is important to making society better. If your concern is to make a meaningful carreer, one that betters the quality of life of people around you, you could choose any kind of engineering. You'd just have to aim at working on something that actually makes a difference. I mean, for example, as a chemical enginner, you could work on water treatment or on making biological weapons. It's all up to you.

    In the end, just choose what you'd like to study. If you like electromagnetism, electric enginnering is a great choice. If you like thermodynamics, go for chemical or mechanical engineering, and so on.

    Hello thanks for making time to answer my question i really apreciate it, becouse im really having a hard time choosing my career. You being an electrical engineer could you tell me some important tips about the career and wich fields are more essencial to society.

    As an electric enginner you could work in several places (I think all of these qualify as being important to society). In any of these, you could work on projects, building, operation and maintenance.

    - Power generation;
    - Transmission lines;
    - Substations;
    - Industry plants such as: oil rigs (onshore and offshore), oil refining, petrochemical, paper and pulp, mining, ore refining, textile, food industry plants, siderurgy, automobilistic industry, airplane industry, sanitation (water pumping and water treatment stations, mainly), machinery manufacturing, etc;
    - Hospitals, Public Buildings, Large Commercial Buildings, Subway, etc.

    Actually, almost any kind of industry depends on electric energy. Any plant that isn't auto-sufficient (that has enough fuel or energy to be autonomous) will need electric energy. And here in Brazil, even plants that are auto-sufficient, can actually generate more than they need and they sell the rest to the grid. So electric enginneers will be needed in almost any industry.

    If you like the legal side of things and still wants to do electric engineering, you could also work on:
    - Electric sector regulation (fiscalization of electric sector agents)
    - Depending on your country regulations, you could also work on electric energy market (buying and selling electric energy)

    There also another honorable one: teaching.

    As for the tips:

    - Learn everything your teachers throw at you (and more if you can). You may not know its importance now but you should learn just for learning;
    - An electric enginner shouldn't only know electromagnetics. You should learn well at least the following: classical mechanics and thermodynamics. An electric engineer always interfaces with other enginners (you can't do anything by yourself), such as chemical, mechanical, civil, etc. And you have to "talk the same language". I mean, for example, you can't get lost when:
    -- A mechanical engineer talks of exergy or entropy;
    -- A chemical engineer talks of gibb's free energy;
    -- A civil enginner talks of bending moments of a structure;
    - Learn well mathematics: analytic geometry, linear algebra, calculus, statistics, numerical methods, differential equations, complex variable calculus, just to name a few. Even you don't end up applying all of it, it'll be worth learning because it'll teach you how to think as an engineer;
    - Your career doesn't start after you gradute. I has started already. To learn all the stuff I mentioned, you have to already know a bunch of high shool math, physics and chemistry. Also, some interesting job opportunities may come from colleagues or teachers. In the future, your colleagues will be in the same stage as you and they will know other people that you don't. So you should try to be a good student at university.

    You can ask, have you done all this yourself? Well, no. I learned the hard way. I work on a oil company and I had to learn thermodynamics recently. I can garantee: it was way harder than when I was at the university.

    Hope this helped.

    Cheers!

    Million thanks =), this help me alot for understending more about the career, i know i will enjoy doing this kind o stuff, that will help to be good at it and helping society. Hey we are latin americans, i live in El Salvador.
