Dave, check out this Australian politician's post:

 :wtf: comments are even worse... Can you make a video about wind turbines sustainability, dedicating a few minutes to correct with actual data that idiotic post and mythbusting some of the more common misconceptions?

"human stupidity knows no limits"
Yeah just about sums up that comment section.

Someone:
There is a good thesis titled "Embodied Energy Analysis of New Zealand Power Generation Systems" it quickly sums up the energy balance of wind and hydro compared to gas turbines while using realistic lifespans for all the types of plant. Unsurprisingly the lifecycle energy cost of the gas plants are 2-3 times the output energy, while wind is the inverse of this and produces around 5-20 times more energy than was used in its lifecycle. This is by counting the fuel that enters a thermal plant as energy while not counting the wind input to a wind turbine as energy, wikipedia has a list using the calculation that does not count the "fuel" input at all:
https://en.wikipedia.org/wiki/Energy_returned_on_energy_invested

helius:
A bare comparison of energy use is not really apples to apples since different forms of energy are different in terms of value and scarcity. That being said, a comparison like the one above makes very little sense and is more contrived than helpful.

Someone, that's a major economical advantage for wind turbines. Feel free to invest your own money in wind turbine technologies. You will make a killing and laugh all the way to the bank.
