Ecological Engineering Methods - Primary and Secondary Methods of Producing Energy

Primary and Secondary Methods of Producing Energy

We have to distinguish between Primary and Secondary methods of producing energy. Making hydrogen from water by electrolysis will use more energy than is available in the hydrogen, because processing always has nonzero wastage. When the hydrogen is produced there are all the emissions for generating electricity from fossil fuels for electrolysis, but when the hydrogen is used in automobiles as fuel the automobiles will emit harmless water vapour. If power is made from fossil fuels, then the hydrogen automobile fuel, as a whole, causes even more emissions than directly burning fossil fuels in automobiles.

Famous quotes containing the words primary, secondary, methods, producing and/or energy:

    The primary distinction of the artist is that he must actively cultivate that state which most men, necessarily, must avoid: the state of being alone.
    James Baldwin (1924–1987)

    Readers are less and less seen as mere non-writers, the subhuman “other” or flawed derivative of the author; the lack of a pen is no longer a shameful mark of secondary status but a positively enabling space, just as within every writer can be seen to lurk, as a repressed but contaminating antithesis, a reader.
    Terry Eagleton (b. 1943)

    I conceive that the leading characteristic of the nineteenth century has been the rapid growth of the scientific spirit, the consequent application of scientific methods of investigation to all the problems with which the human mind is occupied, and the correlative rejection of traditional beliefs which have proved their incompetence to bear such investigation.
    Thomas Henry Huxley (1825–95)

    We have no more right to consume happiness without producing it than to consume wealth without producing it.
    George Bernard Shaw (1856–1950)

    The flattering, if arbitrary, label, First Lady of the Theatre, takes its toll. The demands are great, not only in energy but eventually in dramatic focus. It is difficult, if not impossible, for a star to occupy an inch of space without bursting seams, cramping everyone else’s style and unbalancing a play. No matter how self-effacing a famous player may be, he makes an entrance as a casual neighbor and the audience interest shifts to the house next door.
    Helen Hayes (1900–1993)
