"why does America have such huge air con usage and England none?" Because a significant part of America is hot, and England is not(I had lived in England for years). It is not an "It will be fine if we install AC", but an "if we don't install air conditioner we will die" and I am being serious here, Las Vegas would be inhabited without AC . Also England is wet so this means that before cooling the air, you will have to condense the water, and that takes lots of energy, making them inefficient in UK. South of North America is very hot in summer but also dry, so it is very efficient in energy consumption. 35c on multiple days!! That is nothing. In most of Spain you will get 40-45 peaks with 35c minimum over months in summer, very few clouds for three months.
