Wind Farm, Seen From the Air
Wind Farm,  Seen From the Air
Wind power is the conversion of wind energy into a useful form of energy, such as electricity, using wind turbines. At the end of 2008, worldwide nameplate capacity of wind-powered generators was 121.2 gigawatts (GW).[1] In 2008, wind power produced about 1.5% of worldwide electricity usage;[1][2] and is growing rapidly, having doubled in the three years between 2005 and 2008. Several countries have achieved relatively high levels of wind power penetration, such as 19% of stationary electricity production in Denmark, 11% in Spain and Portugal, and 7% in Germany and the Republic of Ireland in 2008. As of May 2009, eighty countries around the world are using wind power on a commercial basis.[2] Large-scale wind farms are connected to the electric power transmission network; smaller facilities are used to provide electricity to isolated locations. Utility companies increasingly buy back surplus electricity produced by small domestic turbines. Wind energy as a power source is attractive as an alternative to fossil fuels, because it is plentiful, renewable, widely distributed, clean, and produces no greenhouse gas emissions. However, the construction of wind farms is not universally welcomed because of their visual impact and other effects on the environment. Wind power is non-dispatchable, meaning that for economic operation, all of the available output must be taken when it is available. Other resources, such as hydropower, and standard load management techniques must be used to match supply with demand. The intermittency of wind seldom creates problems when using wind power to supply a low proportion of total demand.[3][4] Humans have been using wind power for at least 5,500 years to propel sailboats and sailing ships, and architects have used wind-driven natural ventilation in buildings since similarly ancient times. Windmills have been used for irrigation pumping and for milling grain since the 7th century AD. In the United States, the development of the "water-pumping windmill" was the major factor in allowing the farming and ranching of vast areas otherwise devoid of readily accessible water. Windpumps contributed to the expansion of rail transport systems throughout the world, by pumping water from water wells for the steam locomotives.[5] The multi-bladed wind turbine atop a lattice tower made of wood or steel was, for many years, a fixture of the landscape throughout rural America. When fitted with generators and battery banks, small wind machines provided electricity to isolated farms. In July 1887, a Scottish academic, Professor James Blyth, undertook wind power experiments that culminated in a UK patent in 1891.[6] In the United States, Charles F. Brush produced electricity using a wind powered machine, starting in the winter of 1887-1888, which powered his home and laboratory until about 1900. In the 1890s, the Danish scientist and inventor Poul la Cour constructed wind turbines to generate electricity, which was then used to produce hydrogen.[6] These were the first of what was to become the modern form of wind turbine. Small wind turbines for lighting of isolated rural buildings were widespread in the first part of the 20th century. Larger units intended for connection to a distribution network were tried at several locations including Yalta in 1931 and in Vermont in 1941. The modern wind power industry began in 1979 with the serial production of wind turbines by Danish manufacturers Kuriant, Vestas, Nordtank, and Bonus. These early turbines were small by today's standards, with capacities of 20–30 kW each. Since then, they have increased greatly in size, while wind turbine production has expanded to many countries. The Earth is unevenly heated by the sun, such that the poles receive less energy from the sun than the equator; along with this, dry land heats up (and cools down) more quickly than the seas do. The differential heating drives a global atmospheric convection system reaching from the Earth's surface to the stratosphere which acts as a virtual ceiling. Most of the energy stored in these wind movements can be found at high altitudes where continuous wind speeds of over 160 km/h (99 mph) occur. Eventually, the wind energy is converted through friction into diffuse heat throughout the Earth's surface and the atmosphere. The total amount of economically extractable power available from the wind is considerably more than present human power use from all sources.[7] An estimated 72 TW of wind power on the Earth potentially can be commercially viable,[8] compared to about 15 TW average global power consumption from all sources in 2005. Not all the energy of the wind flowing past a given point can be recovered (see Betz' law). [edit] Distribution of wind speed The strength of wind varies, and an average value for a given location does not alone indicate the amount of energy a wind turbine could produce there. To assess the frequency of wind speeds at a particular location, a
The Electric Albatross By Eric Peters on 6.6.11 @ 6:07AM Electric cars make sense at amusement parks and golf courses -- and on the road, if the road is mostly flat, it's nice and warm out (but not too warm) you've got money to waste, don't have to go very far (especially in winter) and don't mind waiting a couple hours before you can go someplace else. Otherwise, they're marvelous. The hype about electric cars is still years ahead of the actuality. If by actuality you mean an electric car that isn't more compromised than Arnold's political career. I remember covering the GM Impact/EV back in the early '90s, almost 20 years ago. Most of the press swooned; a few Californians bought (well, leased) them. Some even liked them (that's California for you and also because California doesn't have winter; more on this below). The car was a money pit for GM, despite all the hoopla and the government kickbacks. And today? Cut through the farrago of Happy Talk and the real-world boondoggle's still the same. The range of the latest electric cars is said to be better. But it is always couched in the ubiquitous marketing con, "up to." And under ideal conditions. Your actual mileage will vary. Consider the Nissan Leaf. On a full charge, Nissan touts a 100-mile range. It doesn't tout what the range will fall to when it's 16 degrees outside and the capacity of the Leaf's battery declines by "up to" 20-30 percent, which it will as all batteries do when it is very cold out. Now add the additional load on the battery to power things like the heater/fan -- and the lights, which you will probably need when it's dark outside. There are other forms of loading, too. Passengers and Stuff. Everyone knows that a gas powered car goes slower and burns more fuel the more it's loaded down with passengers and cargo. The electric car is not immune from the same physical laws. Add a few hundred pounds of weight and it's going to need more energy to do the same work and that means more draw on the battery, which will mean reduced range as well as reduced performance. Summer's not so hot, either -- as far as optimizing an electric car's range. You'll probably want to run the air conditioning, which will draw power from the battery pack. And high heat can be as unkind to batteries as bitter cold. So, let's say the real-word range of a car like the Leaf is 60-ish miles under less-than ideal conditions. That is, in the real world. That might work for close-in commuting. But it could be an uncomfortably close shave if you live in the 'burbs, 20 or 30 miles out. At least with a gas-fueled car, you can refill the tank in a few minutes and be back on your way. But when the Leaf runs out of juice, you're not only looking at an hour or more downtime to induce a partial charge (a full charge takes several hours) you'll need to locate one of the special 220V charging stations the Leaf requires. This EV does not just plug into any household 110V outlet. The 220V station is faster -- if you can find one. Just what our typical stressed-out commuter needs -- right? The Chevy Volt at least addresses that problem by carting around its own portable (and gas-fueled) generator, so that when your "up to 40 miles" range on electric power alone fizzles out, you're not stuck. The car's gas engine kicks on, pumps juice into the battery, which then runs the electric motor -- and keeps you moving. (The Toyota Prius plug-in hybrid operates on the same principle.) Which is lovely except it concedes that gas power is still better than electric power because without that gas engine, the Volt (and the Prius) ain't a goin' no damn where -- not very damn far, anyhow. All this would be kind of funny in a latter-day Pinto kind of way except for one thing: The government never forced the taxpaying public to underwrite Pinto ownership. Electric cars like the Leaf and Volt come with luxury car MSRPs -- until Uncle Sam transfers about 20 percent onto the backs of you and me. The Volt's MSRP is $40,280. The Leaf's MSRP is $32,780. What lunatic would pay BMW/Lexus money for either of these things? The answer, of course, is only a few (well-heeled) lunatics of the posturing "green" variety -- posturing because by definition, if you can spend BMW/Lexus money on a new car, worrying about the cost of gas is an abstraction. People who really have to worry about spending an extra $10 or $20 at every fill-up don't buy $32k-$40k new cars. If they do, that's why they're having to worry about the cost of fuel. So, enter Uncle -- who is very generous with other people's money. "Buy" a new Volt or Leaf or one of the other electric Turduckens now available and he will send you a check for $2,500-$7,500, depending on the model. Nissan even advertises the actual cost of its car After Uncle ($32,780 less $7,500) to make the thing seem more appealing. In summary: The prudent fellow who buys a $15k (and 41 MPG) Ford Fiesta pays full fre
