Answer by Dolphin lover
Wind can turn a wind mill, which generates electricity.

And flowing water can produce hydro electricity. (that, you will have to look up)

Answer by October
They can turn a generator that produces electircty.

Answer by sideways
This has to be for homework right?
Wind turbines produce electricity by turning the engine

Answer by kylem
With the right way of hooking it up, a windmill can be used to do both those things, and it’s (obviously) powered by wind.

Answer by Shereef
Windmill is the answer as it works by wind power and can both generate electricity and pump water

Answer by Gerri V
w call it a windmill

Answer by generbee
yes…. if there are more of you doing this. definitely you will save some

Answer by ThinkTank™
No. Unless everybody will shutdown lights at the same time then tell the electro plant to shutdown the water driving the plant’s turbines.

Answer by skraith
It will not save any water at all. The point of a hydro-electric dam is that the water flows through without being lost. Granted, because of bad seals inside the turbines there is probably some water lost, but it’s negligible. For all practical purposes each bit of water that enters the dam exits the other side unchanged.

Therefore turning off lights will not save water, it’ll just mean the power company has to pass less water through the dam.

Answer by Edgar VSB
It’s depend on how huge the refrigerator.
For home refrigerator, usually they put cooling condenser pipe along refrigerators body. And it’s ok.
For huge refrigerator, chiller, Air Cond etc. there is two type cooling condenser.
One with air cooled, the other with water cooled.
It’s depend on location (Ambient Temperature) & how big.
Water cooled, more complicated, more energy needed (water circulation pump).
With air cooled, just fan motor.
But some Plaza / Mall / Hotel etc, they used water cooled type, and pumping the warm water for toilets, kitchen sink etc.
Once again, depend on location & how big.

Answer by Fabian G
It depends on the size of refrigerator, but I do not think you water cooling refregirator can use less energy than let state an A++ refrigirator.

Answer by DnR
Tell them to turn the lights off when they leave a room. When in the shower…… get wet turn water off……soap up….turn water on….rinse….turn water off for good……GET OUT OF THE SHOWER……turn lights off when they leave the bathroom! Most of all stop sleeping with the lights on!

Answer by Jonas Rybnicek
I concur with most of the stuff written by the previous person answering, only I would change: tell them to not use the shower if they have a bath tub. It conserves much more water than shower, its superior because you actually know how much water spend while washing. The problem with showers is that you dint know how much water deplete. You just stand there for 1 min and you spend more water than a half of a bath tub.
As for the waste- recycle, recycle and last but not least recycle.
Electricity is probably the hardest to conserve, its part of our daily life just turn the lights off. And if there are personal in school, turn on only the number which will be used, so If someone is not working on a computer, just turn it off.

Answer by Payoja
Water and Electricity are the essential needs of todays life. But it is a serious isssue to conserve these natural resources without wastage. People should be more serious about the proper utilization of these resources. Only without the same, we will be aware of its importance. Some tips,
1) Switch off the lights and power plugs when not in use.
2) Give awareness and importance of these resources to the children.
3) Use power saving tubes and lamps.
4) Ensure switch boards and wiring connections are properly installed and maintained.
5) Take part in energy saving program atleast half an hour everyday.
6) Use rain water storage tanks for future use and domestic needs in rainy season.
7) Close water taps properly when not in use. Repair and maintain properly the water storage tanks and taps without leakage.
9) Conduct awareness programs in schools and colleges about the conservation needs.
10) Use water resuse systems.

Answer by Amerson
water wheels worked as pumps for irrigation , which was animal powered.
Wind mills , had common usage as Grinders for cereals.

Answer by The Oracle
Yup – indeed they were. Wind “mills” were used to grind wheat into flour, as were water mills. Many towns in England still have a “millpond” and “millstream” where the flow was diverted from the main river and sent to the mill.

Old watermills can be converted to generate electricity through relatively easy modifications using the original water wheel and gearing, but with the power going to a generator and a battery bank instead.

Answer by paducahbill
They were used as sources of energy also, water will would turn a mill and grind corn and not product electricity. So yes, they were used as sources of energy. Wind mills were used to pump water.

Answer by Breath on the Wind
First you have to know the wattage of your water pump.
Then you have to determine how many solar panels will be needed to run the pump or you might find it cheaper to undersized the solar system but provide it with a battery back up for a reasonable length of time. If the time extends beyond your plan then you will not be able to run the pump all day.

So you might additionally need to know how long each day you will need to run the pump.

Photovoltaic panels are DC electricity as would be any battery backup, but the pump is no doubt 220 AC. This means you will need an inverter to make the conversion.

Here is one example of a system with a battery back up: http://www.mrsolar.com/page/msos/CTGY/backup

Answer by bigoinie
You can use iodine tablets, add a small amount of bleach, boil it, or use an ultrafilter.

Answer by crissy_jo
My first answer would be with electricity, but I am guessing that since you are throwing in the solar power, electricity is not even an option. Therefore you would have to filter it that is if by purifying you mean removing all contaminates you would have to filter. If by purifying you simply mean kill anything that is alive you can use chemicals such as chlorine or boil the water by fire.

Answer by roderick_young
I’m not sure if this counts as solar energy to you, but you can put the water in a clear plastic bottle, like a 2-liter soda bottle, or a glass bottle, and leave it out in the sun for 4 hours (8 is better). The ultraviolet will kill most pathogens.

If you mean no solar energy because the skies are dark, you can use ordinary Clorox. Just 8 drops to a gallon of water, and let it stand. If you can let it stand in the sun, so much the better. See the link below.

Answer by Jerry Lee
I do not think it would actually boil, but it might get much warmer. If you are uncomfortable with it, you might install an instrument (thermometer) or speak to your pool / solar contractor (maybe a mechanical engineer). It might be possible to heat water for use in a nearby house.

Answer by Amy
They should be installed so that when the pump is not pumping the water into the panels, the water drains back into the pool. So the panels will just be sitting there empty, happy as can be.

Take a look at this schematic (scroll down), http://www.altestore.com/store/Solar-Pool-Heaters-Pumps/Unglazed-Solar-Pool-Heating/AquathermSun-Swim-Pool-Packages/Aquatherm-Solar-Pool-Heating-System-315-sq-ft/p8227/

wind mills, turbines and solar cells

Answer by *haggisbasher*
Wind – gives turbine energy by turning windmills which produce electricity, sun -produces solar energy and water produces – hydro energy.

Answer by fiat_knox
The kinetic energy of wind and water drive turbines, e.g. the vanes of a wind farm, which in turn drives an armature inside a dynamo. The movement of the dynamo’s armature in a magnetic field produces an electrical current, which is then distributed through the national grid.

Solar power uses photoelectric cells which directly turn light from the Sun into electricity, which is then distributed where it’s needed.
