Is peat better than coal?
Peat is the most damaging fuel in terms of global warming; even worse than coal. It has a lower calorific value than coal (generating less energy per tonne when it is burned) and yet it produces higher CO2 emissions per unit, so it is the least climate-efficient way to produce electricity or heat in Ireland bar none.
Why should we not use peat?
The carbon in peat, when spread on a field or garden, quickly turns into carbon dioxide, adding to greenhouse gas levels. 3. The unique biodiversity of peat bogs is lost. Rare birds, butterflies, dragonflies and plants disappear.
Do people still use peat?
Some peat (about 700,000 tonnes a year) is still produced in the UK. But, thanks to campaigning, the use of home-grown peat has declined. Peat use is still too high, though, and most demand is now being met by imports from Ireland. Around 7% comes from Baltic nations.
Why is peat bad for the environment?
Peatlands store a third of the world’s soil carbon, and their harvesting and use releases carbon dioxide, the major greenhouse gas driving climate change. The biggest environmental risk from peatlands is if they catch fire, which happened spectacularly in 2015 in Indonesia on land cleared for plantations.
What are the 4 types of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.
What process caused the peat to become coal?
Under the right conditions, peat transforms into coal through a process called carbonization. Carbonization takes place under incredible heat and pressure.
