Revisiting wind turbine impacts – Erroneous recent calculation highlights need to assess renewable energy sustainability claims

Watts Up With That?

Guest essay by Paul Driessen

Foreword:

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 guide the analysis, this column lays mine out, crunches the numbers, and concludes that replacing the 2.85 terawatts of electricity generated worldwide in 2016 – while ensuring stored power for just 48 windless hours – would require:

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…
