Green Energy Reality Check

The advocates for green energy do not have a clue about the practical political, environmental and infrastructure costs required to implement their dream. Here are practical issues to be considered.

Two green-dream fantasies are heading for a massive and costly collision. 

Firstly, they dream of generating all grid power from wind and solar propped up by battery storage (such as lots of giant Tesla batteries and pumped hydro).

Secondly, they dream of replacing all petrol, diesel, and gas cars, trucks, and buses with electric vehicles, powered by more batteries.

But wind farms do well if they can average about 35% of their rated capacity, with low predictability, while solar panels average just 25% of their capacity, produced intermittently.

To stabilize a green energy system without using hydrocarbons will require an eye-watering quantity of batteries, costing as much as 200 times the cost of any wind or solar facility needing backup.
