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.
