Actually, most power stations reduce their output at night when demand for electricity is lower. Many types of power plant need to be kept running through the night, however, even if they are not really producing that much electricity. The reason is that it can take more than a day for a very large power plant, started from dead cold, to come up to operating temperature. So very large plants (typically nuclear or coal-fired) are simply throttled back at night, throttled up during the day, and shut down as infrequently as possible.

How does making electricity produce carbon dioxide?

The main electricity sources that generate carbon dioxide are thermal power stations where hydrocarbon fuel (gas, oil, coal) are burned to produce heat and steam to drive the generators. Carbon dioxide is a natural product of the combustion of hydrocarbons.However, making electricity does not necessarily make carbon dioxide as electricity can be generated by several other methods:Nuclear power stationsHydroelectric power stationsWind powerSolar powerGeothermal power

Is it a better option to produce electricity as compared to hydroelectric power stations?

Hydroelectric power stations certainly have their advantages and disadvantages, as do all forms of electrical generation. Probably the best solution is to use a combination of different means of producing electricity, with hydroelectric stations as part of the mix.

How do nuclear power stations operate?

Basically, all power stations adopt the same method to produce electricity. A turbine is caused torotate. A generator is attached to the shaft of the turbine. As the turbine turns, electricity is produced inthe generator. This electricity is sent out through transmission lines to a distribution station of theElectricity Board.In hydroelectric power stations, the turbine is turned by flowing water. In thermal power stations,steam is produced by heating water in a furnace which burns coal or oil. In nuclear power stations, thesteam is produced by the heat generated in the fission process.

Can gravity be used as a source of energy?

Absolutely. At hydroelectric stations, for example, the power of gravity is harnessed to produce electricity.

Does electricity produce carbon monoxide?

Electricity - no. But burning of fossils fuels (in thermal power stations and for other uses) lead to a release of carbon monoxide.

Plant that burns waste to produce electricity?

Biomass power stations. (Regular power stations that burn coal can easily be converted to burning biomass (vegetation), reducing pollution, just by changing the fuel.)

What devices use nuclear power?

Power stations produce electricity fronm nuclear power. Submarines and naval vessels produce propulsion power from the same source. Nuclear reactors tap nuclear power. So do nuclear weapons.

What type of electricity is produced in power stations?

The vast majority of power stations produce alternating current (AC) electricity. They may use nuclear, coal, oil, gas, or garbage as fuel, or they may use flowing water or blowing air, but the same kind of electricity is produced, regardless of the fuel used.

How do coal power stations and wind farms generate electricity?

Coal power stations burn coal to heat water to produce steam, which is then used to spin electricity turbines to generate electricity. The burning coal releases carbon dioxide.Wind farms have blades which turn in the wind to spin electricity turbines to generate electricity. There are no harmful carbon dioxide emissions.

Why is South Africa investing on gas-fired power stations?

South Africa is investing on gas-fired power stations because gas is a cheaper natural resource, it is efficient and does not produce a lot of pollution when it is burnt to generate electricity.

Do geothermal power stations make pollution?

No. Construction equipment used to build the station will burn fossil fuels and produce some pollution. When the station is complete it will produce pollution free electricity. The station will require some electric power from the grid to operate, and some of that electricity may be produced by coal powered plants which do produce pollution, but the geothermal power station will not produce pollution.
