That's right, all four answers are correct!

Peat is still mined in Europe today and used in many different ways. Most of the extracted peat is used in horticulture as a planting substrate (BUND n.d.). However, peat is also still burnt as fuel in power plants, e.g. in Estonia, Ireland and Finland (European Commission 2016), even though the energy yield from this only accounts for a fraction of the energy consumed in these countries. Peat is also used in the cosmetics industry (BUND n.d.) and burned for whisky production (Paal 2016). However, many countries have recognised the importance of peatlands and are trying to restore them after peat extraction.
