Electricity prices

[Jerry_Atrick]

You're able to get free electricity today because of solar; not coal.

 

If electricity prices are going to double in real terms it is because governments mismanage the rollout - just like In the UK.

Banks could assist here.

Why don't they offer "solar loans" - where they fund the installation of enough panels and battery that you don't have any debit bills.

The repayment amount is set to the average of your last 12 months power bills. 

So there's no financial impact to the user but then in 6 or 8 or 10 years, you're not paying for power.

I worked in the industry for nearly 14 years and still have close ties to it. I am also thinking of getting back into it. SA wants to build another 13GWs of intermittent generation (for a 3.5GW max demand grid) So not from the Murdoch press. As you can see in the photo I shared earlier the turbines rotor are well above any turbulance, shading from buildings. Most of the shadowing comes from the turbine next door. See the attached photo for how far the turbulence lasts. (Hornes Reef) Surprised me considering how efficent the blade is. When we use to hang glide, you would hardly feel the wake of a sailplane but a hanglider would give you a fair old thump.  Realistically apart from Nimbyism it makes sence to build them in the citys or in really close vicinity. Low line losses and less transmission from the actual windfarms.  The people that want them tend to live in electorates in the citys where WTGs and large solar farms arent situated. Adelaide parklands would be the ideal spot for a solar farm. Again, close to load centre. Doze all the trees and there you have it.

How did they Manage to get the mists forming down wind of the Turbines?  Nev

[Siso]

Same way as you get water vapour forming of a wing. 

 

 

[facthunter]

IF you understood things better you would know what you suggest is impossible. The cloud above big Planes wings is caused by low pressure and high  REL humidity and it only forms over the wing and moves with the Plane. It's like a Lenticular Cloud in shape. Any contrails are from the H2O formed by Burning Hydrocarbon fuel and they don't form always depending (again) on Humidity. at the Planes altitude Nev

That's wishful thinking Marty. Banks offering solar loans. They seem to be continually cutting down what they have to offer rather than increasing it. My bank has closed most of it's physical branches, sacked most of their staff and now only offer housing and business loans, nothing else.

Blades are very long, very high lift wings putting out several thoudsand horsepower, large vortices unless you are suggesting AI. This photo has been around for a long time. The vortices would be traveling down wind. Maybe these guys understand better than you!

Notably, visual evidence from Horns Rev 1 (Hasager et al., Citation2013) verifies that under suitable humidity conditions, wake-induced cloud generation occurs downstream of offshore wind turbines. The spiral wake induces upward motion of warm and humid air parcels adjacent to the ocean surface, causing adiabatic cooling that triggers vapour condensation upon reaching the dew point temperature. This thermodynamic process has been successfully reproduced using the mesoscale meteorological model Meso-NH coupled with LES (Joulin et al., Citation2020). However, microscale wake dynamics affected by rotor-generated clouds have not yet been comprehensively studied.

If you see mist hanging on a hill and stand at that line , you will see the prevailing wind condense the water as the pressure rises from the compression or the temp cool as the height rises(not sure which) and blow over the hill until it gets down the other side and evaporate again. From a distance it looks like it is just hanging there.
