Environmental impact of electricity generation electricity sector is unique among industrial sectors in its very large contribution to emissions associated with nearly all air issues. Electricity generation produces a large share of Canadian nitrogen oxides and sulphur dioxide emissions, which contribute to smog and acid rain and the formation of fine particulate matter. It is the largest uncontrolled industrial source of mercury emissions in Canada. Fossil fuel-fired electric power plants also emit carbon dioxide, which may contribute to climate change. In addition, the sector has significant impacts on water and habitat and species. In particular, hydro dams and transmission lines have significant effects on water
Lower sulfur oxides Jupiter's moons, and Venus contain significant amounts of sulfur oxides. Some compounds reported by early workers such as the blue "sesquioxide", SO, formed by dissolving sulfur in liquid SO appears to be a mixture of polysulfate salts of the S and S ions. These species are all very unstable and are observed as fleeting intermediates in the gas phase. At a few millibars pressure, the relative stabilities are SO > SO > SO. Sulfur monoxide (SO) and its dimer (SO) have been trapped at low temperature. Disulfur dioxide (SO) is a dimer of sulfur monoxide. It has C structure (planar).
