geothermal pollution

shared by mcgarrdan98 on 12 Mar 13 - No Cached
  • Emissions generated during the construction phase include exhaust from vehicular traffic and construction equipment, fugitive dust from traffic on paved and unpaved roads, and the release of geothermal fluid vapors (especially hydrogen sulfide, carbon dioxide, mercury, arsenic, and boron, if present in the reservoir). Activities such as site clearing and grading, power plant and pipeline system construction, and transmission line construction would have more intense exhaust-related emissions over a period of 2 to 10 years. Impacts would depend upon the amount, duration, location, and characteristics of the emissions and the meteorological conditions (e.g., wind speed and direction, precipitation, and relative humidity).
  • Most impacts to ecological resources (vegetation, wildlife, aquatic biota, special status species, and their habitats) would be low to moderate and localized during the construction phase (although impacts due to noise could be high). Activities such as site clearing and grading, road construction, power plant construction, ancillary facility construction, and vehicle traffic have the potential to affect ecological resources by disturbing habitat, increasing erosion and runoff, and creating noise at the project site. Impacts to vegetation include loss of native species and species diversity; increased risk of invasive species; increased risk of topsoil erosion and seed bank depletion; increased risk of fire; and alteration of water and seed dispersal.
  • Solid and industrial waste would be generated during construction activities. Much of the solid waste would be nonhazardous, consisting of containers and packaging materials, miscellaneous wastes from equipment assembly and presence of construction crews (food wrappers and scraps), and woody vegetation. Industrial wastes would include minor amounts of paints, coatings, and spent solvents. Most of these materials would likely be transported off-site for disposal.

  • Wind Energy, like Solar Energy is fully sustainable, being generated by natural wind flows, which in the U.K. are reliable enough to guarantee a stable, near constant supply of energy. Wind Power can be easily set up, either at home (see related article) or on a larger scale, by energy suppliers keen to meet government targets to reduce carbon emissions that are produced by conventional power stations.

  •    Solar energy is our birthright like the air we breathe or the water we drink. Solar Home Plans and  cost effective   Solar Hot Water Projects  are the gateway into a "Solar Age"  of energy independence. Fossil fuels are no longer necessary to keep the wheels of civilization turning. Build your own solar heating system.  Explore the Strawberry Fields Book Store  for more information. Alternative energies like solar energy will increase in value as fossil fuel prices escalate making energy efficient,  solar houses more valuable. Solar collectors, solar hot water systems, heat storage vaults, photovoltaic electricity, solar panels, and solar greenhouses will soon become the standard rather than the exception to the standard in the near future According to Buckminster Fuller "We have wondered too far from the roots." An energy crisis can only be avoided only if we learn to rely on a diffuse, sustainable resource like the sun. Become part of this green economy and travel on the  Green Train and learn about Solar Rebate Incentives and Cheap Electricity

wind history

  • Since early recorded history, people have been harnessing the energy of the wind. Wind energy propelled boats along the Nile River as early as 5000 B.C. By 200 B.C.,
  • Commonly called wind turbines, these machines appeared in Denmark as early as 1890. In the 1940s the largest wind turbine of the time began operating on a Vermont hilltop known as Grandpa's Knob. This turbine, rated at 1.25 megawatts in winds of about 30 mph, fed electric power to the local utility network for several months during World War II.

  • People have harnessed the tides and used its energy for many centuries. Tide mills—which are the precursors to today’s tidal power plants— have great similarity to water wheels. The difference is that water must first be collected from the incoming tide before it can be released to rotate the water wheel.
  • he oldest, excavated tide mill is dated to the year 619.

DOE - Fossil Energy: Current Technology for Producing Hydrogen - 0 views

  • Today, most hydrogen in the United States, and about half of the world's hydrogen supply, is produced through the steam reforming of natural gas. The U.S. demand for hydrogen currently is about 9 million tons per year. Of this amount, about 1.5 million tons is merchant hydrogen production that is sold to refineries and chemical plants. In refineries, hydrogen is produced as a by-product of naphtha reforming, and any supplemental hydrogen is produced from steam reforming of natural gas. The chemical industry also uses hydrogen, mostly to manufacture ammonia and other nitrogen-based fertilizers. Hydrogen for the chemical industry is also produced from steam reforming of natural gas, although some chemical plants use coal gasification (i.e., partial oxidation) to produce hydrogen. In total, about 95 percent of U.S. hydrogen production for supplemental refinery needs and the chemical industry is produced from natural gas using steam reforming technology.

    "Wave energy is the transport of energy by ocean surface waves, and the capture of that energy to do useful work - for example, electricity generation, water desalination, or the pumping of water (into reservoirs). Machinery able to exploit wave power is generally known as a wave energy converter (WEC)."

  • Tide mills, in use on the Spanish, French and British coasts, date back to 787 A.D.
  • Tidal energy is a type of energy that produces electricity and other forms of power through the use of water.
  • The tide moves a huge amount of water twice each day and although the tidal energy supply is reliable and plentiful, converting it into useful electrical power is not easy.
  • ...6 more annotations...
  • The first involves converting the power of the horizontal movement of the water into electricity. The second involves producing energy from the rise and drop of water levels
  • Although the technology required to harness tidal energy is well established, tidal power is expensive, and there is only one major tidal generating station in operation. This is a 240 megawatt station at the mouth of the La Rance river estuary in France.
  • There are three prototypes of tidal energy devices: horizontal axis turbine, vertical axis turbine, and oscillating devices
  • Tidal energy is not on the list of sustainable energy technologies the UN agencies even though for islanders it is our best hope for large amounts of affordable clean power.
  • Turbines, similar to wind turbines, can be anchored to the sea bed to generate electricity from tidal currents
  • Tidal energy has an efficiency of 80% in converting the potential energy of the water into electricity
