Research Report: does solar power contribute to global warming - 1 views

  • But only about 12 percent gets turned into electricity, and the rest is reradiated as heat--which contributed to Global Warming
  • solar panels trap a greater amount of energy from the sun than the natural terrain (since it is black) and consequently retains that energy on earth contributing to the rising temperatures on the planet.

Wind Turbines Impact - 2 views

  • The most noticeable impact a wind turbine places upon the environment is noise pollution.
  • This is down to the noise, and many people compare the sound output of a wind turbine to a small jet engine.
  • Another disadvantage regarding a wind turbine and it's impact on the surrounding environment can be expressed with the term "visual impact" or "visual pollution".

Tidal Wave Energy - Quick Guide to Costs,Investment and How Tidal Generators Produce Ti... - 1 views

  • .In this form of Tidal Power,a Barrage is built near the coast where water is collected during the periods of high tides.During low tide the barrage allows the water from the reservoir to move towards the ocean or sea.The potential energy of the water at a higher level is converted to electricity using Turbines.

Research Report: does solor powers pollution than CO2 when compared to fossil fuels? - 0 views

  • But as much as it poses a health risk, a group of researchers from the National Renewable Energy Laboratory point out that the relative risks are still light when compared to the use of fossil fuels

Energy waves lesson - 0 views

  • Here’s rule one when it comes to waves....the waves move, the particles don’t. The wave moves from place to place. The wave carries the energy from place to place.

Wind Development - 0 views

  • Negotiating power purchase agreements
  • In some states, where the electricity market has been deregulated, it is possible for the owner of a wind project to sell electricity directly to customers.  However, wind developers usually sell their electricity to electric utilities, which sell the electricity to customers. T his is usually done by negotiating a power purchase agreement, which is a contract requiring a utility to buy the electricity from a wind farm at a certain price over a certain period of time.  In some cases, an alternative arrangement is reached, in which the developer owns a share of the project long enough to mak

Infrastructure Battle: Renewable Tidal Energy vs. Telecommunications - 1 views

  • first tidal energy turbines
  • Both technologies require room for periodic ship-borne maintenance and repair access, with subsurface equipment which could impinge on the other facility if they're too close. And if one of the turbines breaks, as happened in 2010 with an earlier tidal turbine in the Bay of Fundy, PC Landing worries it could damage the nearby cable.

Research Report: what are the best uses for solar power - 1 views

  • A quick search on TreeHugger shows that ' solar power ' most often occurs in connection with producing electricity and only secondarily in connection with solar water heaters
  • Compared to electrically heated Water , Solar Water Heating is 57% of the internal rate of return, the scientists found

How Is Wave Energy Used to Generate Electricity? | eHow.com - 0 views

  • Earth is composed mainly of bodies of water---about 71 percent of the earth's surface is water. Ninety-seven percent of that is found in the oceans. Because the earth's surface is curved, the sun heats it unevenly. This causes winds to blow across the water and generate waves. The sun and moon also exert their gravitational pull on the earth, triggering wave-producing tides. Wave motion energy can be harnessed and generated into electricity.

Wind power - Wikipedia, the free encyclopedia - 0 views

  • Sailboats and sailing ships have been using wind power for thousands of years, and architects have used wind-driven natural ventilation in buildings since similarly ancient times. The use of wind to provide mechanical power came somewhat later in antiquity. The windwheel of the Greek engineer Heron of Alexandria in the 1st century AD is the earliest known instance of using a wind-driven wheel to power a machine.[15][16].

Tidal Power - 0 views

  • A dam-like structure is constructed across an estuary to trap a high tide of water and then let it pass through turbines to generate electricity. The water flow can generate electricity on the falling tide only, or on the falling and rising tide.
