Thread: Grid can go 75% renewable

All this push towards renewables wont make much difference in real terms.

Magnetic shift and its impacts are going to make "Climate Change" and the push to other energies seem like a small almost insignificant issue.

Could someone advise of any major country in the World who achieve 75% renewables?

Not parts of countries like Canberra but whole countries who do not import electricity from terrible coal fired power stations elsewhere.

They are only terrible to you because you are pushing a failed narrative.

Coal fired power stations are many times more reliable than any of the “renewables” including hydro.

If renewable technology ever gets to a point where it is reliable, and can actually supply enough energy to remove the need for coal fire power stations, promote it then.

Right now these renewables are proving to be nothing but grossly expensive fairytales.

Does that include the current situation with the Callide stations? Or the WA one that has no coal because of financial mismanagement?

And there be the problem.

Mismanagement and neglect is causing no end of problems with some of the coal fired power stations but I don't so renewables filling the gaps.

Not disinformation John.
If a panel performs at less than 80% of its expected output after 25 years, it will be covered under warranty. That is what I said in relation to Tim's post on battery warranty.
We mostly sell Canadian Solar panels, as the price is right, performance and quality is excellent, but after 25 years, they must perform at over 84.4% or they will be covered under performance warranty.

Not quite right. The capacity factor co-efficiency factor figures are not easy to come by.......... but here are some from 2018 and nearly all are over 30%.

Vic does have quality wind resources (and **** coal, haha)

Kiata was state of the art back then and achieving 47%, the newer turbines are higher.

I have attached an article from the dreaded WUWT regarding teh experience in negotiating a contract for wind energy in NZ.
I found it fascinating and wonder if there are Australian companies being pressured into similar arrangements.
