Yahoo reports about a quarter of vegans say they would eat it.[0] MSU survey found that 35% of people overall would eat cultured meat[1], including a majority of people aged 18-40)[2].
It's not the majority of the population, but it's certainly not 0%, and certainly appears to be well into double-digit percentages.
People are price-sensitive, so if it costs more than regular meat it will have a tough time gaining significant marketshare, but there's very clearly a sizable portion of the population who do want this, anecdotal surveys of your friends notwithstanding.

Why is this difference presumably not an ethical concern for you, but it is with lab-grown meat?
Differentiating on energy intensiveness sounds like an empirical claim, so I'm going to ask about the empirics.
It's not 'lab grown meat', it's 'cruelty free meat' or 'eco steak.'
