What is the source of energy that drives the water cycle?

Heat from the sun that warms water in the Oceans, rivers,and lakes. The water evaporates goes up inot the clouds, evaporated watre dropplets cling to dust particles in the atmoshpere, These become clouds, and as soon as enough water is clinging to one drop it beginn, rivers to rain, as if the clouds are to heavy to hold anymore. If it is cold then it will snow. This falls to the ground and (if snow melts) runs into the ocean rivers and lakes. REpeat Process with heat from the sun. ^^

It's use water to get electricity\nA electricity is produce by turbine , there is a several way to make this turbine working by motor, by wind flow, by water,....\nIn case of water the hogh velocity of water during shut down make the turbin turn and produce electricity

Energy that enters the system from the surroundings.

it produces a lot of energy

diameter of the capillary and the surface energy of the material that makes up the capillary relative to water.

All living things emit energy - mostly in the form of heat.\nAll living things produce energy and even the ones most efficient at using the energy the produce lose some to the surronding environment.

Basically energy derived from steam or heat escaping from deep underground.  Kinda like harnessing "Old Faithful".\nHTH

Moving water as in a river or water tuned to steam can turn a turbine and produce electricity.  http://en.wikipedia.org/wiki/Turbine

You did a great job of identifying the common energy found in the general press.  However, you did leave out Biological, Geothermal and Oceanic Energy.  Geothermal sources are well documented there are several untapped sources that could add almost 1% to the US energy sources.  Others who have responded to you shared Biological sources such as Methane and Ethanol.  However, they failed to mention the Methane Hydrates that are in the Caribbean Sea.  (This is technically a fossil fuel rather then a renewable.)\n\nWhen you spoke of water I take it you were thinking hydro-power such as dammed river basins.  There are three primary Ocean based sources that I think do not get much play.  Thermal, Wave and Tidal are all Ocean water power.\n\nThermal power makes use of the difference in deep water cooler temperatures and warmer surface temperatures.  Using a Rankine or Sterling engine it should be possible to use the cooler water of the deep ocean (between 200 and 400 meters) to return the working fluid to fluid and extract power from the difference in the phase change or fluid expansion.  The issue is to achieve this depth requires that the power extraction needs to be fairly far into the ocean and unless the power generated is used to convert water to hydrogen the transfer of the power under water is inefficient.\n\nWave energy uses two different mediums, one is the difference in air pressure in a cylinder as the waves raise and lower the pressure in the cylinder increases and reduces  and act as a kind of low pressure bellows for moving air.  Whether this would be enough for producing significant energy remains to be seen.  (A new method using a fluid and a valve that takes advantage of both the increase and the decrease of pressure exerted by the changing water levels appears to have some merit.)  The other method is a direct mechanical energy conversion where the rising wave front raises a buoy which either pulls up on a crankshaft or a cable and in the trough the cable length or crank returns to minimum.\n\nAnd finally there is tidal, there are two different types of Tidal or Ocean current extraction.  The first is the most common in which a bay or tidal estuary is dammed (barricade) and the difference in heights between the Ocean and the tidal estuary form the head or force applied to a submerged turbine.\n\nThe other method is called Tidal Stream.  In this method the turbine is submerged in a natural narrowing such as an inlet or in deeper water and take advantage of the flow or currents of water energy.  Of the two the Tidal Stream is the least common and is in it's infancy.  As you can place a large quantity of Tidal Stream converters in open Ocean waters it has the greatest opportunity to generate the most energy for the least amount of environmental change.\n\nHowever, I do have a question for you.  In your consideration of Solar energy you probably have explored Photovoltaic Cells and Solar Furnaces; however, have you explored Solar Chimneys?  There was an experiment done in the late 70's in Spain in which a large metal "Chimney" was painted black and as it heated up cooler surface air would enter at the bottom and rise towards the top where a turbine was installed.

The water cycle: water evaporates on the Earth's surface (oceans, plants...), gets into the athmosphere, forms clouds then falls back to Earth as rain or snow, and the cycle restarts.

only energy is transferred.  Think about it - if you're in the  ocean and a wave comes by, you bob up and down but aren't swept away.

The sun is the original source of energy. This energy is used by green plants that are situated at the beginning of food chains as they are consumed by herbivores, also known as primary consumers. Green plants are known as autotrophs or producers only because they are at the start of food chains. You never learn of a food chain that begins with an animal.

water... it's the nutrients, minerals etc. IN the water that makes it grow

Earth's water is always in movement, and the water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Since the water cycle is truly a "cycle," there is no beginning or end. Water can change states among liquid, vapor, and ice at various places in the water cycle, with these processes happening in the blink of an eye and over millions of years.\n\nAlthough the balance of water on Earth remains fairly constant over time, individual water molecules can come and go in a hurry. The water in the apple you ate yesterday may have fallen as rain half-way around the world last year or could have been used 100 million years ago by Mama Dinosaur to give her baby a bath.

Kinetic energy is the actual amount of energy in an object. In this case, it would be water.\n\nThe faster a stream flows, the more sediment it can carry. This is called the stream's carrying capacity or load.\n\nAlso, when a stream flows faster, it can pick up objects that are of larger size & heavier. It can deposit these larger items further downstream than if the stream was moving slower.\n\nWhen a stream slows down, it will lose it capacity to carry it's load & the sediments will start dropping out of the water. They are then deposited in the streambed.\n\nStreams that move faster are more likely to cut into their bed, making the stream deeper over time.\n\nHope this helps.\n\n:)

STEAM TURBINE IS THE BEST EXAMPLE\n in this process steam rotates the turbine convert heat anergy to mechanical energy, and then mechanical turbine rotates the dynamo which creates electricity.
