How much power is produced in the UK by wind power?
By the End of 2008 around 3,287.9 MW of power being generated in United Kingdom through Wind. Taking it to 8 place in the list of Top Ten Countries producing electricity through Wind.
Why is solar energy not your main source of energy?
Because coal is plentiful and cheap, and there are plenty of coal plants around to burn it. There are many workers making their living by mining, processing, and shipping coal. To change to sunlight and wind will displace these workers (necessitating re-training), and it will inconvenience some pretty rich and powerful people. Also, solar is not cheap to install, and the wind is inconsistent. Power companies like to be able to control their output.
What is expensive because it requires a lot of electricity?
The most expensive is probably solar cells. Wind power is expensive too, compared with fossil fuel power or nuclear, and has to be subsidised to make it practicable as part of a power network. This of course may change in the future if fossil fuels go on getting more expensive due to increased world demand and dwindling reserves. Solar cells (photo-voltaic) convert sunlight into electricity directly using silicon crystals-these are described as 'poly-crystalline PV panels'. They produce DC current at a low voltage depending how many cells are connected in series but usually at 12v DC. To feed into a normal domestic system this has to be converted to 110v 60 Hz in N America, or 240v 50 Hz in Europe. This requires a piece of electronic kit called an inverter which effectively does the opposite of a rectifier, ie converts DC to AC. Assuming the house is connected to the electricity grid, surplus solar output can be exported, if the electricity supply company runs such a scheme. This is useful as obviously max solar power will be generated in the middle of the day, and not at all at night when max domestic demand usually occurs. An alternative is to have a large lead-cell battery which can be charged at 12v DC directly during the day and used at night. This would be the preferred system if in a remote area without a grid connection. The drawback of course is the cost of the installation. I only have figures for the UK in 2008. A typical cost of installation of a 2KWp (ie 2KW peak) system given by my electricity company is from (that feared word!) £11,848 (double the figure for US dollars). This includes an inverter but not a battery. In UK conditions this is expected to generate savings in the electricity bill of £175 per annum. There is also in the UK an income of £68 pa from a Renewable Obligation Certificate-but I discount that, it is not a real saving and has to be paid from taxation by other people, it's just an incentive to install the system. So you are left with spending about £12,000 for an annual saving of £175. Now I rate that as expensive. The payback time comes to 68 years, assuming nothing goes wrong in that time and no maintenance is required. I'm not sure what evidence there is for long time durability of these panels, but I'm sure the manufacturers won't guarantee them for that length of time. Probably 10 years max. In fact no manufacturer can even promise to be in business in 68 years time! So if you go in for such a system it can only be because you are a dedicated 'green', and moreover have deep pockets. Of course the UK is not noted for abundant sunshine. In Arizona or Australia the situation may be much more favourable, and also in remote places the costs may look different if the alternative is hauling fossil fuel over a long distance to power a diesel engine for example.
Where is nuclear energy being used now?
All around the world! In the United States alone there are 104 nuclear reactors producing around 20% of our electricity. Large power reactors are used to produce electricity for the public. Smaller reactors are used to make radioisotopes for medical treatments and for research into physics. Naval reactors provide propulsion for submarines and ships.
How much UK pounds in a ton?
A ton is 2000 pounds (in the UK or anywhere else).
What is the most practical power in UK?
Electricity
What is the main sorce of electricity in uk?
Nuclear power.
How the UK make electricity?
The majority of he UK's electricity is generated by coal or gas-fired power stations. We also use nuclear power, wind and wave generators.
How much power is generated from solar power?
In theory the maximum amount of power arriving from the sun is about 1.3 kilowatts on every square metre. The standard 1.6 square metre solar panel such as installed on roofs in the UK is rated at 220 watts.
What percentage of electricity in the UK is produced by nuclear power?
19.26 - in 2004
How long would electricity last in the UK or US if something wiped out most of humanity?
this depends... much of the power in the UK is supplied by nuclear power, and these power plants are mostly regulated by computors.. i assume its down to luck more than anything else.
How much does a solar powered car cost in the uk?
around £50,000 pounds in the uk
Can solar power be used in the UK?
Absolutely.Solar panels create energy even on overcast days and it is sunny sometimes! Try building a cheap one at home to see if you get much power.
Why are there so many coal burning power stations in UK?
To generate electricity.
How much wave power does the UK use for electricity?
Very little ! While wave-power is a clean way of generating electricity, sadly, people think more about whether wave generators will spoil the view, than generating cleaner energy !
What is mains electricity?
Mains electricity is nothing but main source of power in an installation. From the mains the power is then branched out to different end usage.
In uk electricity is generated as?
