How Wind Power Works

When the wind blows, particles in the gust of air are moving quickly. And that motion carries kinetic energy, which can be captured and harnessed to create electricity. The principle behind a wind-electric turbine isn't too different from an ordinary dam -- only it's capturing wind instead of water.

El Nino

El Niño, an ocean phenomenon of the Pacific Ocean. El Niño occurs when the southeast trade winds slacken or cease, preventing cool, nutrient-rich water within the Peru Current from moving up from moderate depths to replace warm surface water .) With the absence of the nutrient-rich water, plankton, a major source of food for fish, dies off, resulting in a major disruption of the ecosystem.
