Translates to about 330 kWh/month per person.

That's much more than my household is using now (about 350-400 kWh/month for the past two months; it's a cold winter). Yearly average is more like 300 kWh/month. That's like 100 kWh per person per month. Another 200 kWh/month left for use elsewhere: trains, restaurants used, office, school, etc.

Developed country; lights; TV; computers; washing machine; fridge; heating, water heater for shower; aircon - all electric.

You're mixing up US traffic and UK traffic. A big difference (and not because one of them is driving on the wrong side of the road). European drivers are generally better than US drivers (much better traffic schools, for starters - if you still don't believe me, check the accident rates: accidents or deaths per distance travelled).

In Europe, many roads don't have markings to begin with. Plenty of 80 km/hr roads that have no road markings whatsoever. Problem with that? Start learning to drive properly. Or adjust your speed. That you're allowed 80 km/hr doesn't mean you should. That your car is capable of speeding, doesn't mean you should.

Same with pretty much all other aircraft; if your engine fails right after takeoff in a regular plane you're bound to crash just as hard, if not harder.

Autogyro (engine off) landings are a routine maneuver for heli pilots, see a.o. (search "helicopter landing without engine" on youtube for thousands of results).

Synthesising fuel oil may be more expensive than pumping it up from the ground - the Fischer-Tropsch is what kept the Nazi's war effort going (sorry for the unintended Godwin of this thread). It's not that inefficient, really. It's just that oil is and always has been so crazy cheap that very little research has been done in these processes. I'm sure given the need producing carbon based fuel oil using solar/hydro/wind power will not cost that much more than using fossil fuels.

If an engine on heliocopter fails - it's time to crash.

And that's just not true. When the helicopter's engine fails, the pilot will disconnect the rotor and go into autogyro mode, basically becoming a glider. The rotors don't lose all their lift - look up autogyros, a kind of aircraft with unpowered rotor and vertical landing ability - but continue to rotate and allow for a very smooth landing. The main problem is less control (steering) and little choice of landing spots. Given a spot to land (a field is enough, water works great as well) a helicopter can make a perfectly smooth emergency landing without engine power.

You call it "basic stats" but to do statistics you need hard data to work with, which is probably really hard to get on for such a subject.

First of all, how do you define your data points? Which factors are you looking at, and how do you quantify them? Are you sure you don't forget about any factors, like how many oranges a person eats per day? Or are you really sure that eating oranges is not in any way related to how many video games one plays? For a really sound study all that has to be taken into account, and when there is a correlation found that's only a first step. Causation still needs to be established.

When examining depression among shoot-em-up players, there was evidence for increased risk before the researchers controlled for all the confounding factors, but not afterwards.

This makes it sound like playing lots of video games is a effect of depression rather than the cause. Which sounds just as plausible to me than it being the other way around. Just like people already at risk of social withdrawal, for them video games can be a great time killer.
