7. Find your best example of a modern wind turbine...

... that's been running for at least a year or two and post its numbers here.

The 44 MW Eola wind farm in Nicaragua claimed a 60% capacity factor a few years ago, but I wasn't able to find recent numbers, possibly because I'm not fluent in Spanish.

A few exceptional wind farms claim capacity factors around 40%, most muddle along at one third or less of their nameplate capacity.

Nicaragua has abundant hydroelectric capacity they rely on when the wind is not blowing. Unfortunately hydroelectric power is not reliable either. Venezuela's electric grid is mostly hydroelectric. Extreme drought caused electric outages that put the nails in the coffin of Venezuela's already crippled economy.

Places like Denmark use fossil fuels when the wind is not blowing adequately, which is most of the time.

Wind and solar will always be supplemental energy sources in any kind of industrial economy capable of building large scale solar and wind installations.

A society powered entirely by "renewable" energy sources (no fossil fuels, no nuclear, no environmentally destructive large hydro projects) would look nothing like the fossil fueled society many affluent people in places like Denmark or California now enjoy.

The gas industry is not afraid of the solar or wind industry, solar and wind are in effect the bling they wear while pimping gas. The largest industrial projects on earth today are gas extraction and distribution. There are more than enough gas reserves to destroy the earth's natural environment as we know it.

Wind and solar will never displace fossil fuels simply because the wind doesn't always blow and the sun doesn't always shine.

Fossil fuel use is like smoking. You don't quit smoking by smoking "light" cigarettes. In terms of health, not smoking is overwhelmingly preferable to smoking. Hybrid wind-solar-gas power grids are the "light" cigarettes of the power industry.

The innumeracy and other sorts of denial expressed by wind and solar advocates is very similar to the denial of smokers. They become unwitting advocates of the gas industry, denying the impact of the fossil fuel or big hydro projects required to make their favorite "renewable" energy systems viable.
