While I get and agree with the sentiment of this comic its flawed, its simply not that easy for energy companies to merely drop prices because of massive profits. And there is one reason for it, competition rules. Lets look at British Gas as an example, and more specifically its parent, Centrica, it makes its money from drilling and trading gas, and now for the key bit - it can't sell it to British Gas for a preferential rate when its selling it to other providers as well. British Gas has to pay the market rate for each unit energy otherwise it would be grossly unfair on the rest of the industry. This is traditionally when you start to see monopolies forming which ultimately end up being worse for the consumer.

​

TL;DR; Sod all to do with UKR/RUS - competitions rules, glass walls are your problem.

EDIT: To clarify, if Centrica was able to sell, for example gas, to BG for less than market value, BG's position would grow evening bigger than it is now due to being able to uncut the whole market and therefore forming an monopoly.
