The West is instutionally captured by established power structures whose financial and political profit is dependant on a new Cold War, in which the bulk of the Red Scare-ish craziness is realized as yellow perilist propaganda.
It's still relevant because Western masses still think manipulation of social media sites is exclusive to US adversaries like Russia and China despite the fact that US and other neocolonialists use way more sophisticated techniques of manipulation of the public by the usage of technology.
It's funny how this level of scrutinization only applies to journalists who are critical of US/NATO foreign policy of neocolonialism and US empire expansionism & hegemony, but never to organizations like BBC, CNN, NYT who have been exposed to churn out some of the biggest lies, especially against US propaganda targets.
Power engineering is vast. Machinery, generation/transmission/distribution, high voltage are the main topics. They're very much intertwined with each other so maybe it's pointless to divide it into topics. Of course it's still part of the broader electrical engineering subject.
