Revisiting wind turbine impacts – Erroneous recent calculation highlights need to assess renewable energy sustainability claims | Watts Up With That?:
"An article I wrote several weeks ago had a couple of stupid math errors.
This column attempts to correct them – and take readers on a journey to the futuristic world of 100 percent “clean, green, sustainable, renewable” wind energy. 
Since the assumptions always replacing the 2.85 terawatts of electricity generated worldwide in 2016 – while ensuring stored power for just 48 windless hours – would require:
guide the analysis, this column lays mine out, crunches the numbers, and concludes that

• 14.4 million 1.8-GW turbines … 570 million acres (30% of the Lower 48 US states) … and 1.4 trillion Tesla 100-kWh lithium-ion battery packs!
• Need stored electricity for seven windless days? 50 million turbines, the US-Canadian land mass, and 5 trillion battery packs should do it.

Disagree with this analysis?
Wade in with your own.
Let’s have a wide-open debate, before renewable energy activists and politicians lock us into an energy future that might be horrendous for humanity and planet. (Or might save us from calamitous climate change.)..."
