Unsourced meme statistics aren’t going to convince any green energy believers. Hell, I generally agree with the sentiment and even I’m not convinced. I’ve seen so many memes like this that are verifiably wrong that I’m calling bullshit without a source.
The full quote comes from the book "Carbon Shift: How Peak Oil and the Climate Crisis Will Change Canada (and Our Lives)" and says:
The concept of net energy must also be applied to renewable sources of energy, such as windmills and photovoltaics. A two-megawatt windmill contains 260 tonnes of steel requiring 170 tonnes of coking coal and 300 tonnes of iron ore, all mined, transported and produced by hydrocarbons. The question is: how long must a windmill generate energy before it creates more energy than it took to build it? At a good wind site, the energy payback day could be in three years or less; in a poor location, energy payback may be never. That is, a windmill could spin until it falls apart and never generate as much energy as was invested in building it.
The 3 years or less is what I was looking for. What classifies a location as being a good wind site? (Probably lots of open space) Why would there ever be windmills built on poor wind sites, if it takes so long to even pay off the cost of the construction/installation of the windmill itself?
Not an attractive return on investment in my mind at all, many businesses wouldn’t bother investing in something with a 3 year return like this
Excellent statistics to show to green energy believers.
You also have the case where on windless days,power is supplied to keep the blades rotating to stop damage to the bearings.
Also the incredible amount of birds killed by the blades.
This is an excellent example of one of the Cabal's brilliant scams to damage the World's economy!
