Answer: Thermal inversion
Explanation: Thermal inversion or change the position of the air layer, when the warmer layer of air is above the cold layer, which is usually not the case. It happens due to a change in the normal temperature gradient, i.e. when the gradient becomes inverted. Such thermal inversions can occur in oceanic areas with a lot of upwelling near the coasts. Thermal inversion also occurs when sun radiation is less than radiation from the earth, which is the case during the night. The significance of these inversions is great, especially for air quality in polluted environments such as urban. The strongest inversions are during the winter and can then be dangerous due to poor air quality, which is measured by the AQI (Air Quality Index). The higher the AQI index, the greater the risk of bad air, that is, the worse air.

Answer:
Becoming cleaner comes with an increased cost of electricity. According to this graphic the increase in the UK annual cost of energy between 2007 and 2015 for an average house was 37%
Explanation:
According to the graph, the average yearly cost of energy in the average UK household in 2007 was £954, or around $1239 USD, and it rose to £1311, or around $1703 USD in 2015. So, the energy bill increase on average by £357 or around $464 USD, which represents an increase of 37%.
£954 = 100%
£357 = X
X= £357 * 100% / £954
X = 37.42 %
The average monthly bill will then be around £109, or $142 USD, which, compared to the US, it is slightly more expensive (21% more expensive), since according to the US Energy Information Administration, the average monthly electric bill for an average house in 2017 was $111 USD.
