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:

    “A primary function of art and thought is to liberate the individual from the tyranny of his culture in the environmental sense and to permit him to stand beyond it in an autonomy of perception and judgment.”
    —Lionel Trilling (1905–1975)

    “Words are always getting conventionalized to some secondary meaning. It is one of the works of poetry to take the truants in custody and bring them back to their right senses.”
    —William Butler Yeats (1865–1939)

    “With a generous endowment of motherhood provided by legislation, with all laws against voluntary motherhood and education in its methods repealed, with the feminist ideal of education accepted in home and school, and with all special barriers removed in every field of human activity, there is no reason why woman should not become almost a human thing. It will be time enough then to consider whether she has a soul.”
    —Crystal Eastman (1881–1928)

    “Death is an incident producing clay. Use it, mold it, learn from it.”
    —John Gilling, British screenwriter. Dr. Knox (Peter Cushing)

    “After the planet becomes theirs, many millions of years will have to pass before a beetle particularly loved by God, at the end of its calculations will find written on a sheet of paper in letters of fire that energy is equal to the mass multiplied by the square of the velocity of light. The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
    —Primo Levi (1919–1987)
