Renewable energy is the energy that is extracted from natural sources, such the Sun (solar), earth (geothermal), wind, and water (hydropower). These sources are renewable because they can be replenished by the same natural sources within...

This lesson plan introduces the ways that engineers study and harness the wind. Students will learn about the different kinds of winds and how to measure wind direction. In addition, students will learn how air pressure creates winds and...

Mankind has used the wind as an energy source for thousands of years. Discover other ways the wind is used to make energy.

So you've just heard the "Happy Birthday" song and now it's time to blow out the candles. If you are sitting far away from the candles, you know you'll have to blow harder to get them all out than if you were sitting closer. In this...

Generating technologies for deriving electrical power from the ocean include tidal power, wave power, ocean thermal energy conversion, ocean currents, ocean winds and salinity gradients. Of these, the three most well-developed...

In this illustrated essay from NOVA Online, explore the cyclical process of weather creation and the effects of El Nino on the global weather system.

Determine parameters of weather; including specifically temperature, humidity, precipitation, wind direction and wind speed in this tutorial. During this tutorial, you will relate the jet stream and ocean circulation to the causes of...

Imagine our weather if Earth were completely motionless, had a flat dry landscape and an un-tilted axis. This, of course, is not the case; if it were, the weather would be much different. The local weather that impacts our daily lives...
