Not eco­nom­i­cally vi­able

The Cairns Post - - VIEWS -

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
