The answer is depending on what fuel power plant use and their waste treatment system.
Coal fire would yield CO2, SOx, NOx, dust particulates and Slack. SOx can be treated using scrubber. Particulates and NOx can be prevent using correct Air-Fuel ratio and trapped out using scrubber.
Gas Fire would yield every pollution like Coal except in lower amount of SOx and without Slack.
Hydro power may not yield any pollutants at all.
Temperature can be considered a pollution if it cause ecological damage. Power plant may cause water pollution if they discharge hot water without pre-cool. Same amount of water and temperature may not be considered a pollutant if the river stream is large enough.
In the extraction phase, pollutants such as methane and other volatile organic compounds can be released. During the transportation phase, pollutants like nitrogen oxides and particulate matter are emitted. In the refining phase, pollutants such as sulfur dioxide and carbon monoxide can be generated.
There are currently no geothermal power stations operating in Britain, but some geothermal projects are being developed for the future.
Carbon Dioxide, particular matter, mercury and radioactive trace elements are released/emitted from the fossil fuel thermal power stations and cause damage to the environment. Also, paying for the fuel, clean up and remediation of pollution-prevention. :)
As of 2021, there are around 40 power stations in the UK that use oil as a fuel source. These stations are primarily used as backup or peaking plants due to the higher cost and environmental impact of oil compared to other fuels.
Three pollutants released into the air when fuels are burned are carbon monoxide, nitrogen oxides, and particulate matter. These pollutants contribute to air pollution, respiratory issues, and environmental damage.
Mostly sulphur and carbon dioxode comes out of a power station that burns fossil fuels. But there are some other gases
Is it actually true that "few lichen survive near power stations?" If one take the opening premise that "few lichen survive near power stations" as true, then it is probably down to the fact that power stations (excluding Hydro-electric, waste-burning & nuclear, or in other words "fossil fuel" fired) tend to be sited in highly developed and industrialised locations, as that is where the power is needed the most. The high level of development and industrialisation mean that the location is prone to high levels of pollution from transport, factories, homes, etc. It is perhaps the pollution from the surrounding "city" the lichens have trouble coping with, not the power station.
Power stations use electrostatic precipitators to remove particulate matter (such as dust, ash, and pollutants) from the exhaust gases before releasing them into the atmosphere. This helps comply with environmental regulations by reducing air pollution and improving air quality.
Power stations are bad for the environment because they release greenhouse gases like carbon dioxide, which contribute to global warming and climate change. They also produce pollutants like sulfur dioxide and nitrogen oxides that can cause air pollution, acid rain, and respiratory problems. Additionally, power stations can have negative impacts on local ecosystems, water quality, and wildlife due to their operations and waste disposal.
Nuclear power stations produce nuclear waste. This waste can be radioactive and pose risks to human health and the environment if not properly managed and disposed of. Additionally, some emissions of carbon dioxide and other pollutants can be produced during the mining, milling, and enrichment of the fuel used in nuclear power plants.
Most coal burned in power stations contains small amounts of the metal mercury. This metal is released and vaporized as the coal burns. Some coal, particularly lower-quality bituminous coal, contains nitrogen compounds. The nitrogen in this coal (and sometimes nitrogen from the air) combine with oxygen to produce various nitrogen oxides, some of which catalyze the formation of ozone in the lower atmosphere. Most modern coal-fired power stations have very efficient combustion, so they produce very little carbon monoxide, but some older plants produce significant (but still small) quantities. Carbon dioxide isn't universally considered a pollutant, but it is the main combustion product of coal. Some coal contains sulfur or sulfur compounds. These can be released by burning to produce sulfur dioxide, which reacts with water in the atmosphere to produce sulfurous and sulfuric acids, which are significant components of acid rain.
there are no solar power stations in new zealand
Stella power stations was created in 1954.
Stella power stations ended in 1991.
Rugeley power stations was created in 1963.
Cottam power stations was created in 1969.
Air pollution from power stations can be reduced by ensuring that the effluents are purified before being released into the air. Carbon emissions from a coal station can go through a cleaning process to remove heavy metals from the smog before it is released.
