How much water is used to produce 1 kw of electricity?

User Avatar

Asked by Wiki User

The amount of water used to produce 1 kW of electricity can vary greatly depending on several factors, including:

Type of power plant:

Hydropower: Uses very little water for electricity generation itself, but can require significant water diversion for dam operations and upstream ecosystems. Estimates range from 3 liters per kWh for efficient plants to 15 liters per kWh for less efficient ones.

Nuclear: Primarily uses water for cooling, with consumption varying between 2.5 to 20 liters per kWh depending on cooling technology and water source.

Coal: Requires significant water for both cooling and steam generation, ranging from 1500 to 3000 liters per kWh.

Natural gas: Uses less water than coal but still requires some for cooling and steam generation, typically around 100 to 200 liters per kWh.

Solar and wind: Use no water for electricity generation directly.

Location:

Water availability and regulations can significantly impact water usage per kWh. Arid regions might use more water for cooling due to higher evaporation rates.

Cooling system technology: Once-through cooling systems use more water than closed-loop systems that recycle water.

Overall mix of generation sources:

The average water usage per kWh in a region depends on the mix of power sources used. For example, countries with a high proportion of hydropower will have lower average water usage compared to those relying heavily on coal or natural gas.

Therefore, it's challenging to give a single, definitive answer to how much water is used per kWh. Globally, the average is estimated to be around 2000 liters per kWh, but this can vary significantly depending on the factors mentioned above.

For a more accurate answer, you'd need to specify:

The type of power plant you're interested in.

The specific location of the plant.

The cooling technology used.

With this information, you can find more precise data from relevant sources like government reports, energy agencies, or the power plant operator itself.

Is graphite a conductor of electricity?

User Avatar

Asked by Wiki User

YES!!!

Graphite is an allotrope of Carbon. Anyone carbon atom wants to make FOUR bonds with adjacent atoms. However, in graphite it only makes THREE bonds, leaving a 'loose' electron. This electron is able to move , hence conduction of electricity.

By comparison, Diamond is also an allotrope of Carbon. However, in this case all four bonds are made to adjacent atoms. This leaves no 'spare' electrons, so diamond does NOT conduct electricity.

A third allotrope of Carbon is the Buckminster Fullerene (Footballene). It is thought that the fullerene can act as a 'super conductor'.

Asked by Wiki User

In terms of electricity:
Grounding is putting a conductor from the circuit directly to earth. Guarding is putting some cover or barriers to live electrical wire, outlet or any conductor that are exposed to prevent physical contact that may result to electrical shock.

What are tiny particles that make up electricity?

User Avatar

Asked by Wiki User

Tiny particles that make up electricity are called electrons. Electrons are negatively charged particles that orbit the nucleus of an atom. When these particles are in motion, they create an electric current that can be harnessed for various purposes.

Do satellite dishes emit dangerous rays into a house?

User Avatar

Asked by Wiki User

In terms of injury or harm caused by electromagnetic signals, satellite receiver dishes do not cause any hazards. They are designed to gather and decode very weak signals and emit virtually no electromagnetic radiation.

The only danger is that of bumping yourself walking past them if they are mounted at low level.

How do you connect a 3-wire stove to a 4-wire outlet?

User Avatar

Asked by Wiki User

Answer for USA, Canada and countries running a 60 Hz power supply service.

In order to plug your 3 wire stove into a 4 wire outlet, the easiest way to do so is to change the cord on the stove. This does not require cutting power to the outlet or anything like that.

Anyone who is going to be changing the power cable on any device knows that you need to unplug the cord first, eliminating the need to cut power to the outlet.

The difference between a 3 prong and 4 prong outlet is the ground wire. Both provide 240v power by supplying 2 120v wires (red and black). There is also a white wire, which will be your neutral wire.

The green wire is your ground, and should be bolted to the body of the stove. (Most appliances have a location for attaching the ground wire).

When connecting your wires, there should be 3 wire locations. You should connect one of the two hot wires (red or black), then your white wire in the middle, and then your other hot. The green will be your ground.

How do you convert an electric stove to run on gas?

User Avatar

Asked by Wiki User

If LP orifices were not shipped with the appliance contact your dealer to order them. The conversion set should come with instructions for changing the orifices and for switching the regulator from natural to LP. Look for a small bag or envelope affixed to the back panel of the appliance and read the manual for conversion information pertaining to your unit.

Is baking soda solution a good conductor of electricity?

User Avatar

Asked by Wiki User

Yes and No. Baking Soda (Sodium Bicarbonate) alone is not an "Electrolyte". Stick two electrodes into it and it does not conduct any electricity. But, when you mix it with water, the mixture becomes an Electrolyte solution allowing electrical conductivity between the electrodes. The more Baking Soda you add to the water, the more conductive it becomes. This is a popular additive for people constructing an HHO (Hydrogen, Hydrogen, Oxygen or Browns Gas) generating device. These devices are usually installed on automobiles to increase gas mileage. It is preferred for use as an Electrolyte in these devices because it is non corrosive, non acidic and generally leaves less debris in the solution than other electrolyte additives such as ordinary salt.

How do you make 110 volt worm rods?

User Avatar

Asked by Wiki User

Obtain a steel rod about 5 feet long and secure a wooden handle on it. Tape one side of a cut electrical cord with plug to the top of the metal rod. Tape the other side closed. Poke the rod as far into the ground as possible. Plug the wire into a household outlet (or extension cord). The rod can be moved up and down or to another position. Us the wooden handle if you touch the rod. DO NOT touch the metal part of the rod.

How to split 220 volt into two 110 volt?

User Avatar

Asked by Wiki User

Answer for USA, Canada and countries running a 60 Hz supply service.

Before an explanation of how to do this you should keep in mind that this is for a single receptacle only. If any other receptacles are on the same circuit they will also be changed to 120 volts.

The existing two pole breaker in the distribution panel that is to be replaced should not have a larger rating than a 15 or 20 amps. The wire size from that breaker will be #14 or #12 respectively. The final results of this project will leave you with a 15 amp 120 volt receptacle and one spare 15 amp breaker in the distribution panel.

That said, OK, any 240 volt outlet can be changed to 120 volt by removing the white wire from the 2 pole breaker and inserting it into the neutral bus bar. Remove the other wire (probably black) from the breaker. Remove the 2 pole breaker from the breaker panel. Install two single pole 15 amp breakers into the hole left by the 2 pole breaker. Leave both of these breakers turned off.

Connect the black wire that came off of the 2 pole breaker on to one of the new single pole 15 amp breakers. Re install the cover to the electrical panel, this end is finished. At the old 240 volt receptacle, remove the existing device and install a new 120 volt receptacle.

Materials can be purchased at local building supply store. Remember to take the electrical panel data with you so you have the information for the 2 new breakers. Once you have the new 120 volt receptacle installed, identify on the electrical panel door what the breaker is used for. Leave the unused breaker in the off position. Turn the new 15 amp breaker on. Turn the main breaker back on. Test the new receptacle with a lamp to make sure every thing is OK.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances

always use a test meter to ensure the circuit is, in fact, de-energized.

How do you connect a surround sound system?

User Avatar

Asked by Wiki User

That would be the idea of a "surround sound system". Unless you are talking about hooking up more than one speaker to the same exact port on the receiver. If so than yes, but you will not get true surround sound. For instance: You hook up two speakers to the same port, lets pick the front left channel, and then place one to the front left of the TV and the other to the back right you will get the front left's audio coming from behind you.
