Wind grid future (need to do)

shared by dpurdy on 03 Nov 11 - Cached
  • The dirty secret of clean energy is that while generating it is getting easier, moving it to market is not.
  • While the United States today gets barely 1 percent of its electricity from wind turbines, many experts are starting to think that figure could hit 20 percent.
  • Achieving that would require moving large amounts of power over long distances, from the windy, lightly populated plains in the middle of the country to the coasts where many people live.

  • “The windiest sites have not been built, because there is no way to move that electricity from there to the load centers,” he said
  • The basic problem is that many transmission lines, and the connections between them, are simply too small for the amount of power companies would like to squeeze through them

wave what

shared by dpurdy on 03 Nov 11 - No Cached
  • Ocean waves are a tertiary form of solar energy, in that unequal heating of the Earth’s surface generates wind, and wind blowing over water generates waves. Despite the fact that nearly 75% of the Earth’s surface is covered with water, waves are a largely unexplored source of energy, compared with the progress that has been made in harnessing the sun and wind.

grid solar wind transported

shared by dpurdy on 03 Nov 11 - No Cached
  • Big cities need large amounts of electricity to function. Often, this is transported from generating sites located in remote areas hundreds or even thousands of kilometers away. The question is how to move as much electricity as possible from renewable generation sites like hydro plants and wind parks without impairing the function of the power networks that need it.
  • One of the challenges of renewable power generation like wind and solar power is that it can be interrupted, and this variability affects the stability of the power produced
  • The "smart grid" will create a power network that is more reliable, flexible, secure and efficient

  • Another benefit of condition monitoring is that it allows condition-based maintenance. Instead of replacing components after fixed time intervals based on empirical values, they can be replaced only when required, such as when signs of wear are detected.

wave form

shared by sopranodan99 on 20 Sep 13 - Cached
  • The winds cause waves on the surface of the ocean (and on lakes). The wind transfers some of its energy to the water, through friction between the air molecules and the water molecules. Stronger winds (like storm surges) cause larger waves.

    "Primary sources of noise associated with exploration include earth-moving equipment (related to road, well pad, and sump pit construction), vehicle traffic, seismic surveys, blasting, and drill rigoperations. Well drilling and testing activities are estimated to produce noise levels ranging from about 80 to 115 decibels at the site boundary. Air Quality Emissions generated during the exploration and drilling phase include exhaust from vehicular traffic and drill rigs, 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). Initial exploration activities such as surveying and sampling would have minimal air quality impacts. Activities such as site clearing and grading, road construction, well pad development, sump pit construction, and the drilling of production and injection wells would have more intense exhaust-related emissions over a period of 1 to 5 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). Emissions during this phase would not have a measurable impact on climate change. State and local regulators may require permits and air monitoring programs. Cultural Resources Cultural resources could be impacted if additional roads or routes are developed across or within the historic landscape of a cultural resource. Additional roads could lead to increased surface and subsurface disturbance that could increase illegal collection and vandalism. The magnitude and extent of impacts would depend on the current state of the resources and their eligibility for the National Register of Historic Places. Drilling activities could result in long-term impacts on archeological artifacts and historic buildings or structures, if present. Surveys conducted during this phase

history

  • There are also three main ways that tidal energy is harnessed: Tidal Barrages - A tidal barrage works like a dam. When the tide goes high, the reservoir fills up. When the tide drops the dam lets the water out. In both directions the moving water can spin the blades of turbines to create electricity. Tidal Fences - These are smaller structures than a barrage. A number of vertical turbines form a fence between two land masses. When the tide moves in or out, the turbines spin and generate electricity. Tidal Turbines - These are individual turbines placed anywhere there is a strong tidal flow.
  • Tidal power to turn water wheels and grind grains was used as far back as Roman times and the Middle Ages. The idea of using tidal power for electricity is fairly recent, but the costs have been too high to make it a major energy source. Recent technological advances have shown that it could become a competitive and viable source
  • Tidal turbines are more expensive to build and maintain than wind turbines, but produce more energy. They also produce energy more consistently as the tide is continuous while the wind doesn't always blow.
