Not economically viable
WOULD you like to know how you can be absolutely certain wind and solar energy cannot power Australia?
Imagine every roof and yard has solar panels and every paddock and hill has wind turbines. How much power do you get on a still night? None. And batteries not yet invented can’t help.
Wind and solar aren’t entirely useless; they’re good for yachts and remote outstations. But on the grid they’re pointless and detrimental.
Pointless because they require 100 per cent back-up from coal, gas, diesel, nuclear or large hydro.
Detrimental because their surging and unpredictable nature necessitates complex grid management procedures and expensive power conditioning equipment.
They can’t generate the type of energy needed to make replacements of themselves.
Most won’t generate as much energy as it took to build, transport and fit them.
Wind turbines kill bats and birds and large solar sterilises the ground underneath. Most of their parts can’t be recycled. They’re not economically viable without artificially inflating prices with consumer-funded subsidies. Peter Campion, Tolga
