 "Hydroelectric Power
Hydroelectric power means electricity generated by water power, usually involving sites on rivers where moving water can be directed to spin turbines that activate a generator to produce electricity, or in reservoirs behind dams, where a reserve of water makes a constant, regular flow available from a river with an erratic or seasonal flow. hydroelectric power can also be produced by harnessing tidal action, though that is a more difficult and expensive kind of project and done only on the grand scale.
Hydroelectric power is great."- James Howard Kunstler, The Long Emergency: Surviving the End of Oil, Climate Change, and Other Converging Catastrophes of the Twenty-First Century (Get the book.) |
 "His journeys led him to the hydroelectric power dams of James Bay, Ontario, the uranium mine of Hack Canyon, Arizona, an offshore oil loading platform in Brazil, the freshwater reservoirs of New York's Catskill Mountains, and the garbage mountains of the vast Fresh Kills Landfill (since closed) on Staten Island in New York City. Across a hemisphere, locales so diffuse as to be largely invisible to us are a functional part of McKibben's apartment at Bleeker Street and Broadway. The "place" called New York contains even more of them. "- Alex Steffen, Worldchanging: A User's Guide for the 21st Century (Get the book.) |
| "We've been using hydroelectric power in the United States since the first generating station on the Fox River in Appleton, Wisconsin, opened in 1882. Ten percent of electricity in the United States today comes from hydropower, compared to 40 percent in 1940. Hydro is well understood and fairly dependable. It can be done at scales from a one-household microgenerator on a creek to Hoover Dam, which lights up whole cities. hydroelectric power is produced at about 2,200 sites recognized under the Federal Energy Regulatory Commission." - James Howard Kunstler, The Long Emergency: Surviving the End of Oil, Climate Change, and Other Converging Catastrophes of the Twenty-First Century (Get the book.) |
 "Air-conditioning may not always be an option: with peak power demand occurring during the driest part of the year when reservoir levels are already low, hydroelectric power outages could lead to blackouts during the worst heatwaves. Tourists - especially the elderly - will need to stay away because of the danger of heatstroke, whilst Mediterranean locals might actually prefer to spend summers far away in northern Europe in search of cooler temperatures. Lifestyles will have to change, with people perhaps adopting more Middle Eastern or North African living routines to cope with the heat."- Mark Lynas, Six Degrees: Our Future on a Hotter Planet (Get the book.) "In Switzerland itself, 60 per cent of current electricity comes from hydroelectric power generation, an energy source which may fail during the summer months as streams and rivers run dry. As with the American and Canadian Rockies, the problem is one of timing: even if the total amount of yearly precipitation remains similar to now (and there's no guarantee of that), more of it falling as rain than snow in the winter means that peak stream flows occur earlier in the year, reducing the amount that is available during the summer for human use." - Mark Lynas, Six Degrees: Our Future on a Hotter Planet (Get the book.) "With India particularly dependent on hydroelectric power generation, dwindling summer flows may lead to blackouts and energy shortages during the hottest months of the year. Two of the Indus River's major tributaries - the Chenab and the Sutlej - arise in India and flow into Pakistan. Both will also be suffering the effects of deglaciation in their upper reaches. Conflicts may well break out between these two nuclear-armed countries as water supplies dwindle and political leaders quarrel over how much can be stored behind dams in upstream reservoirs." - Mark Lynas, Six Degrees: Our Future on a Hotter Planet (Get the book.) "The Colorado's water isn't just used to irrigate golf courses in Las Vegas; it also supplies drinking water and hydroelectric power to much of southern California and Arizona. Battles have broken out between different states: in August 2005 protesters in Salt Lake City took to the streets to oppose a plan by the Southern Nevada Water Authority to pump groundwater through 500 miles of pipes south to Las Vegas. The San Joaquin River, its waters diverted to feed the fertile fields of California's productive Central Valley, also mostly fails to reach the sea down its old natural river bed." - Mark Lynas, Six Degrees: Our Future on a Hotter Planet (Get the book.) |
 "As electricity became common, water mills and windmills were nearly abandoned. hydroelectric power is produced in a way similar to water mills, except that the mill pond is replaced with a giant reservoir and water wheels are replaced with turbines. In recent years, there has been a rising movement to generate electricity with windmills. The earliest, built in 1929 in France, used a rotor 66 feet in diameter and generated about 10 kW. Today windmills with aerodynamic designs are grouped together in wind farms."- The New York Times, The New York Times Guide to Essential Knowledge: A Desk Reference for the Curious Mind (Get the book.) "Canada also produces more energy from hydroelectric power than any other country, while the U.S. ranks fourth, and the U.S. ranks first in production of nuclear-generated electricity, and Canada ranks eighth. North America's abundant mineral wealth includes silver, lead, zinc, aluminum, nickel, and gold. Jamaica accounts for nine percent of the world's bauxite production. North America has extensive and productive agricultural lands. The continent produces much of the world's corn, meat, cotton, soybeans, and wheat." - The New York Times, The New York Times Guide to Essential Knowledge: A Desk Reference for the Curious Mind (Get the book.) |
 "The four strokes necessary to run a gasoline engine (left to right): intake, compression, power, and exhaust. hydroelectric power Electricity generated from the energy of running water, usually water falling over a dam. fa Only a small proportion of the electricity in the United States is produced by hydroelectric power. impedance (im-peed-ns) A measure of the apparent resistance posed by an electrical circuit to an alternating current (AC). fa The term impedance is most often encountered in dealing with antennas and speakers in television, stereo, and radio systems."- E.

| "Northern towns also built hydroelectric power stations at what today would be considered a very small scale of operation.
Electrification in the South happened differently. In 1900, the South had few cities, not many factories, and many agricultural trading towns without the means to supply their own power. The enormous flat expanses afforded few exploitable hydroelectric sites. Lack of electricity across vast reaches of the South kept the region mired in backwardness through the 1920s —just when a depression in farm commodity prices occurred as a result of mechanization." - James Howard Kunstler, The Long Emergency: Surviving the End of Oil, Climate Change, and Other Converging Catastrophes of the Twenty-First Century (Get the book.) "It can be done at scales from a one-household microgenerator on a creek to Hoover Dam, which lights up whole cities. hydroelectric power is produced at about 2,200 sites recognized under the Federal Energy Regulatory Commission. All the great sites on major rivers in the United States have been exploited. They are problematic because soil and other material washing down a river deposits silt behind a dam, eventually rendering the dam inoperable. Virtually all the major dams in the United States are less than one hundred years old. All of them have sedimentation problems." - James Howard Kunstler, The Long Emergency: Surviving the End of Oil, Climate Change, and Other Converging Catastrophes of the Twenty-First Century (Get the book.) |
