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:
“Europe has a set of primary interests, which to us have none, or a very remote relation. Hence she must be engaged in frequent controversies, the causes of which are essentially foreign to our concerns. Hence, therefore, it must be unwise in us to implicate ourselves, by artificial ties, in the ordinary vicissitudes of her politics or the ordinary combinations and collisions of her friendships or enmities.”
—George Washington (1732–1799)
“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)
“There are three major offenses against filial piety of which not producing an heir is the worst.”
—Chinese proverb.
Mencius.
“Parents find many different ways to work their way through the assertiveness of their two-year-olds, but seeing that assertiveness as positive energy being directed toward growth as a competent individual may open up some new possibilities.”
—Fred Rogers (20th century)
