    "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"

  • Solar energy originates in the depths of our sun. The sun endures a continuous stream of thermonuclear explosions as hydrogen atoms are fused into helium atoms. We encounter the resultant energy as radiation that strikes the surface of the earth.

  • Tidal energy is most sustainable and beneficial as a tool in a larger tool belt of renewable energy sources needed to meet our energy demands.

    "tidal power is a renewable source of electrical power that is used in addition to other sources of energy. It does not create any emissions that may contribute to global warming. Tidal power is not entirely the most consistent source of electricity though, as it does not adhere to peak usage schedules, due to daily tidal cycles (differing energy harnessing potential between Ebb and Flood tides). Tidal energy is most sustainable and beneficial as a tool in a larger tool belt of renewable energy sources needed to meet our energy demands."

  • Tidal energy is a form of hydropower that converts the energy of the tides into electricity or other useful forms of power. The tide is created by the gravitational effect of the sun and the moon on the earth. Tidal energy is therefore a predictable form of renewable energy, which can be harnessed in two forms:

  • As far as producing electricity goes, tidal energy is one of the cheapest kinds.
  • Since the tidal cycle repeats itself every 24 hours, there is a guarantee that power can be produced this way every day of the year.
  • can help protect delicate coastal areas from storm damage, as well
  • ...4 more annotations...
  • can protect against erosion
  • Even though tidal energy does not produce any kind of pollution, the barrages completely change the coastline. Many animals and birds make their homes on the mudflats around tidal basins. When the tidal energy plants flood these areas, the habitats of these animals are destroyed. Holding the water back also causes silt to build up inside the tidal basin and can cause the released water to take longer to clear from dirt and materials. This can keep the water around the coastline from settling and becoming clear as quickly as it usually does. There is also evidence that using tidal power plants can change the migration patterns of many ocean creatures.
  • Other people think that since tidal energy plants can only produce electricity for about ten hours every day,
  • it is not worth the danger to plants, animals, and ecosystems.

  • Tidal power is a means of electricity generation achieved by capturing the energy contained in moving water mass due to tides. Two types of energy can be extracted: kinetic energy of currents between ebbing and surging, and potential energy from the difference in height (or head) between high and low water marks.
  • Tidal power schemes do not produce energy 24 hours a day. A conventional design, in any mode of operation, would produce power for 6 to 12 hours in every 24 and will not produce power at other times

  • Tidal energy is produced by the surge of ocean waters during the rise and fall of tides.
  • During the 20th century, engineers developed ways to use tidal movement to generate electricity in areas where there is a significant tidal range—the difference in area between high tide and low tide. All methods use special generators to convert tidal energy into electricity.
  • For most tidal energy generators, turbines are placed in tidal streams. A tidal stream is a fast-flowing body of water created by tides. A turbine is a machine that takes energy from a flow of fluid.
  • ...1 more annotation...
  • The world's first tidal power station was constructed in 2007 at Strangford Lough in Northern Ireland. The turbines are placed in a narrow strait between the Strangford Lough inlet and the Irish Sea. The tide can move at 4 meters (13 feet) per second across the strait.

    ". The United States has no tidal plants and only a few sites where tidal energy could be produced at a reasonable price."
