Australian Politicians Confuse Wind Power And Powerful Winds

wind vs wind power

Which of our elected politicians can tell the difference? Read on to find out…

Yesterday all of South Australia was blacked out and parts of the state are still without grid power today. This occurred because a powerful storm damaged transmission lines and the entire state grid automatically shut down as a safety precaution to prevent more damage.

Restarting a grid after a complete shutdown is complex and requires several hours. And it took several hours for grid power to start to be restored.

There is no mystery to what happened. It is very simple:

1. There was a really big storm.
2. Transmission lines were damaged.
3. The grid shut down automatically as a safety precaution, like it should have.

If you don’t believe power lines were damaged by strong winds, here is a picture of high voltage, steel girder, transmission towers near Port Augusta.  The wind bent them over so their tops touch the ground.

This picture shows how unusual the situation was. Transmission towers do not normally lie down on the ground to take a rest.

In addition to gale force winds there were also so many lightning strikes they would have been countless if someone hadn’t counted them and tornadoes. As more detailed information is reported we will probably learn if it was lightning strikes, gale force winds, or a big willy willy that provided the straw that safety precautioned the camel’s back.

Is Solar Panel Cleaning A Waste Of Time And Money?

Solar Panel Cleaning – It’s A Dirty Job, But Nobody Has To Do It

The day your solar panels are installed is the day you will get the best performance out of them.  After that it is all down hill. Admittedly, it is a very shallow hill and it might take over 40 years to get to the bottom, but day one is going to be as good as it gets.

One of the reasons for this is dirt. As soon as your panels are out in the open in the clean air, or not so clean air, dust will start to settle on them, blocking sunlight, reducing their efficiency, and costing you money.

The obvious solution is to pay someone to clean those panels or get out there and clean them yourself. And sometimes this obvious solution will be a sensible course of action. If a dust storm has covered your panels in dirt or pelicans have had a poop party on your roof, then it’s a pretty good idea.

But most of the time solar panel cleaning is not worth it. [Continue reading…]

Misleading Statements On Sunrise Hurt Solar Industry


On Sunday morning the program Sunrise had a segment on solar power and battery storage. While I am glad whenever popular TV takes the opportunity to educate people on these topics, that wasn’t what happened here.
