Grey skies hover above the little island of Malta. Smoke from Malta’s Power Station is polluting the air above it.
Although power stations are regulated by laws to protect human health and the environment, there is a wide variation of environmental impacts associated with power generation technologies.
Burning oil at power stations produces nitrogen oxides, sulphur dioxide, carbon dioxide, methane, and mercury compounds. The amount of sulphur dioxide and mercury compounds can vary greatly depending on the sulphur and mercury content of the oil that is burned.
Oil-fired power stations use large quantities of water for steam production and cooling. When oil-fired power plants remove water from the sea, fish and aquatic life can be killed, affecting those animals and people who depend on these aquatic resources.
Power stations release treated wastewater, which can contain pollutants and is generally hotter that the water in nearby seas, often harming fish and plants.
