Wind Turbine Syndrome | Wind energy: The "least sustainable energy option" - 0 views

  • Wind turbine installations impact vast amounts of land, far more than traditional power plants.
  • Raptors, bats and other beautiful flying creatures continue to be sliced and diced by wind turbines.
  • Principal health issues are associated with noise – not just annoying audible noise, but inaudible, low-frequency “infrasound” that causes headache, dizziness, “deep nervous fatigue” and symptoms akin to seasickness. “Wind turbine syndrome” also includes irritability, depression, and concentration and sleep problems. Others include “shadow flicker” or “strobe effect” from whirling blades, which can trigger seizures in epileptics, “vibroacoustic” effects on the heart and lungs, and non-lethal harm to animals. Serious lung, heart, cancer and other problems have been documented from rare earth mining, smelting and manufacturing in China, under its less rigorous health, workplace and environmental regulations.

  • Wind turbine installations require vast amounts of steel, copper, rare earth metals, fiberglass, concrete, rebar and other materials for the turbines, towers and bases.
  • Wind turbines are supposed to reduce pollution and carbon dioxide emissions. But because backup generators must repeatedly surge to full power and back to standby, as wind speed rises and falls, they operate inefficiently, use more fuel and emit more – much like cars forced to stop repeatedly on freeways.
  • Even huge subsidies cannot cure wind power’s biggest defects: its electricity costs far more than coal, gas or nuclear alternatives – and its intermittent nature wreaks havoc on power grids and consumers.

      Be cautious as this site is obviously anti wind power. The points might be valid though.

shared by butlerlex99 on 12 Mar 13 - No Cached
  • Quick and interesting facts related to solar energy.  For more terms and explanations, consult our solar glossary. One kilowatt equals 1,000 watts. One kilowatt-hour (kWh) equals the amount of electricity needed to burn a 100 watt light bulb for 10 hours. A sunny location (like Los Angeles, California, US) receives an average of 5.5 hours of sunlight per day each year. A cloudy location (like Hamburg, Germany) receives 2.5 hours per day of sunlight each year. A 1 kilowatt peak solar system generates around 1,600 kilowatt hours per year in a sunny climate and about 750 kilowatt hours per year in a cloudy climate. A solar energy system can provide electricity 24 hours a day when the solar electric modules are combined with batteries in one integrated energy system. Solar modules produce electricity even on cloudy days, usually around 10-20% of the amount produced on sunny days. The typical components of a solar home system include the solar module, an inverter, a battery, a charge controller (sometimes known as a regulator), wiring, and support structure. A typical silicon cell solar module will have a life in excess of 20 years Monthly average residential consumption of electricity in the US in 2008 was 920 kilowatt hours. (Source: US DOE) Monthly average residential electricity bill in the US in 2008 was $103.67. (Source: US DOE)

  • Basically biofuel is produced by using ethanol from naturally grown plant matter which allows for a more sustainable and environmentally friendly earth.
  • Bio fuel is a natural alternative from other fossil fuels and is attained from living or biological material that has just died. Basically biofuel is produced by using ethanol from naturally grown plant matter which allows for a more sustainable and environmentally friendly earth. To assist in the manufacturing of biofuel, the plants and plant-derived materials that contribute to its formation includes corn, corn cob, sugar cane, soybeans, flaxseed, rapeseed, vegetable oils, waste cooking oils, animal fats, tall oil and even cow manure. However, at present the most widely used source of bioeenergy is of course wood.

Although the fuel-cell cars themselves may emit nothing but water vapor, the process of producing the fuel cells from hydrocarbons will continue America's dependence on fossil fuels and leave behind carbon dioxide, the primary cause of global warming."

    "The first fuel cell was built in 1839 by Sir William Grove, a Welsh judge and gentleman scientist, who conducted dozens of experiments using his "gas battery."  More than a century later, equipment manufacturer Allis Chalmers plowed a Wisconsin alfalfa field using fuel cell-powered tractor (1959).  Serious interest in the fuel cell as a practical energy generator did not begin until the 1960′s, when the U.S. space program chose fuel cells over riskier nuclear power and more expensive solar energy, using fuel cells to furnish power for the Gemini and Apollo spacecraft and electricity and water for the space shuttle.  Also in the 1960s, the first passenger vehicle, a prototype van, was built by GM (1966); major auto manufacturers began more concerted fuel cell development efforts in the 1990s."

shared by streetscor99 on 11 Mar 13 - Cached
  • * Because there is no combustion in a fuel cell, fuel is converted to electricity more efficiently than any other electrical generating technology available today. * There are no moving parts in a fuel cell stack, making them more reliable and quieter than generators. Even the ancillary systems (fans, pumps, controls, etcetera) in a complete fuel cell unit are relatively mature and simple technologies that should prove extremely reliable.
  • In the past, fuel cells were large and extremely expensive to manufacture, just as the first calculators and computers were. But, just like these products, the cost of fuel cells will quickly come down to consumer-affordable levels with mass production. We are currently in a transition period now, where many fuel cell companies are investing literally hundreds of millions of dollars to gear up for mass manufacturing at the same time they are trying to begin to develop a variety of markets for their product.

shared by turnmaster on 11 Mar 13 - No Cached
  • The conversion technologies from hydrothermal fluids to electricity include flash steam, dry steam, and binary-cycle power plants. Each geothermal electric system is made up of several key components including a: Production well Turbine Generator Injection well. Dry steam power plants are the simplest and oldest design, upon which the two other systems are based. They use a geothermal production well that produces fluid heated by the natural heat of the earth. The steam goes directly to a turbine, which drives a generator that produces electricity. The fluid then goes into an injection well, which is a well that is specifically drilled for the safe disposal of the geothermal fluids.

    "The fuel cell is being considered as an eventual replacement for the internal combustion engine for cars, trucks and buses. Major car manufacturers have teamed up with fuel cell research centers or are doing their own development. There are plans for mass-producing cars running on fuel cells. Because of the low operating cost of the combustion engine, and some unresolved technical challenges of the fuel cell, however, experts predict that a large scale implementation of the fuel cell to power cars will not occur before 2015, or even 2020."

    "A geothermal heating system uses pipes buried more than four feet deep in the earth. That is another reason why it's important for adults to call 811 before they dig in their yard so they don't hit buried piping. The system pumps a liquid through the pipes to absorb the heat and brings it back indoors. A device called a "heat exchanger" takes the heat from the liquid and uses it to heat the air inside the home."

    "Certain studies have shown that a geothermal power plant that could be considered as economically competitive would cost at around $3400/kw installed. Yes, the cost of the construction of a geothermal power plant is much higher compared to a facility producing natural gas, however, the cost of electricity production of the two in the long run would be similar. Initially, the construction cost of the geothermal plant would be 2/3 of the total cost. On the other hand, with a natural gas facility, the cost of the fuel is 2/3 while construction cost is just 1/3 of the total cost.  So this is where geothermal power plant and natural gas energy come into a standoff. In the long run, production rates stabilize and the cost of production for both plants become competitive. One good thing about the pric"
