Polluting everything!
Tassie power the world, that's like the "97% of science" typed argument?
All of the cost of that is incorporated into the solar cost. Its not additional. And there is virtually zero pollution if you use solar energy to produce solar panels.
There is so much to go before,
before renewables will be able to do anything near run the worlds energy needs. It will take those energy needs from fossil fuel to get anywhere close to manufacturing enough solar and wind gear etc, it will cost a fortune, we have all the ideas but not the technology fully and if it were closer than that technologically-wise then we still have to use the old cheap ways to even get started, and when you discover, that climate change is in fact something the world could never have evolved or survived without it happening forever.
Humans wouldn't have made treks across the planet, in fact, climate heating and warming let humans wander near and far and initially wipe out megafauna from 10 to 50 thousand years ago, we could call that creating a disaster, if you wanted to look really hard at it.
Our indigenous people got here, and over a couple of thousand years wiped out the giant wombats, giant roos, even some kind of large toothed cat, a huge mega flightless bird as well, all gone. They had never seen humans and weren't afraid of them, became easy targets, but without climate change, those people may never have got here, because of water highs and water lows, like the Americans 16000 years ago walking onto America, they wiped out all the megafauna there as well, so really Greta Thunberg was about 20 to 45 thousand years too late to stop the unstoppable.
The point I always try to make is that we humans pollute, all our waterways, the bush the cities, throw crap into the seas plastic and tins and cans and christ knows what else, but the climate has changed way way before we burnt oil coal or gas , whatever and sent carbon into the air.
Those fossil fuels mean nothing and to change the world and its modernity to crap, by killing the cheap fuel off, is mad
That is not the problem , the problem is being filthy grubby rubbish dumpers, that is what needs fixing.

Why is natural gas involved nearly everywhere that solar or wind is being used at significant levels?

"There is so much to go before cars will replace horses. I mean they can only go at 5km per hour and they are so costly especially as you have to pay 10 shillings a day for the guy with the red flag to walk in front. Horses cost next to nothing to buy and can run of grass."

You need to look at the whole lifecycle. Solar power has significant environmental impacts in the construction, installation and the decommissioning phases.
The raw materials have to be extracted from the ground - quartz, polymers from oil, aluminum, copper, lead, gallium, selenium, indium, cadmium and tellurium. Processing of the raw materials produces toxic by-products such as silicon tetrachloride.
Mining and industrial chemical processing is energy intenstive. 90% of Australia's solar panels come from China where most of the energy is generated from fossil fuels, mainly coal.
You need to add in the CO2 emissions from the transport costs at each stage.
A solar panel lasts between 15 and 30 years. At the end of its life cycle, it has to be treated as a special waste ie it can't be disposed of in regular landfills in case the toxic materials leach into the soil.
And again for the second time all those costs are incorporated into solar cost. When we talk about electricity costs we always talk about life cycle costs. And again if the energy used is from renewables to produce those components then it will have zero emissions.
do you complain about all the metal in your phones, ipads, houses, transmission lines and coal powered generation plants?

It's not. So it doesn't.
talk about a stupid circular argument based on flawed maths. If you convert that coal power to solar power than it will be clean and have zero emissions. The solar power produced from solar panels is literally tens of thousands of times more power than the power used to create the panels. as you convert coal to solar the probability those panels are produced using solar rises dramatically. Not that it matters because their power consumption is so small its irrelevant.

And if my aunty had balls she would be my uncle.
90% of solar panels used in Australia are made in China. They don't use solar panel power to make solar panels. They use coal power.
Yeah but you can't see that from my place.
If thats an argument about the climate and human progress, it is not even an argument. Every one alive each human does not particularly like change, especially when humans went on a rampage of discovery in the last 300 years of industrial revolution the beginning of the modern world.
If you think on that and are having a shot at me because you think I am a "go back to the good old days" type of person, with a man and a flag and light in front of an old motor car you are incorrect, and obviously don't see what I am saying, in the things I wrote to Seeds.
You are perhaps indoctrinated into the "end of the world" Greta Thunberg Stuff, and frightening children , this is politics , not anything else?
Maybe your young yes?
With all the world in front of you, that's great, but climate change has been and is with us forever it's simple logic.
Going renewable next week, next year, even in 50 to 100 years or a 1000 years! Will not stop the climate from changing.
It will change forever until the solar system is not here at all. and that is simply the way it is.
But right now with all the bad things we have a modern world, where we can do better, but we are a wild animal, so it takes evolution, to gain reasonable behavior in the human animal.
Helping that is invention and modernity, and it is because we invented ways to make energy available to the world. Going backwards by not having that energy, and that is what some want, will be disastrous for the human race, we have enough trouble getting on together now, let alone take away not just mod/cons, but what about the cheap energy used in hospitals anD during PANDEMICS.
So this has nothing to do with change and old road rules, its to do with cleaning our environment, the atmosphere looks after itself, we 8 billion are like ants in the biggest dessert on the earth, insignificant. But remember if you have no power that can keep up, you will not be arguing on BF, or anywhere else , you may not be driving anywhere unless you have 10,000 dollar for a super battery , you need cheap energy to build a propeelor for the wind?? Or a million by millions of solar panels, and you have to dump them when they deteriorate.
Shillings hey? Used to get a pie and sauce for about that, heh heh heh !
IF is a gigantic word!
Also, the value/cost /strength of renewables is now a hugely disputed thing in all aspects.
"IF they can do this and IF they can that", What IF we have to use so much fossil fuel energy to find out?
Yes IF is the biggest word in our language. And doubt is something that has to be totally overcome on all sides for anything to work. Doubt.
AND DISPUTED SCIENCE AND EXXAGERATED SCIENCE makes doubt the next biggest word in our language!
No thats the wrong analogy. These arent independent occurances. If you produce solar generation than the bloody power you use to produce things is solar ffs.

Banned Books Week: Harry Potter and the Censors' Wrath

No!! Its like the singularity, it started everything we think? Reality? You got to have the start? And something else started it (singularity what ever the hell that was)? Now that comment needs a billion question marks hey?
Same here, there is no renewable solar or wind or anything without the old fossil, we can't get pedantic, renewables are also a long long long work in progress, for affordable energy, that we may not even need in a hundred years. the climate panic will revive again when Corona eases , but its bulldust the climate has changed forever and ever. It IS that simple! And you can't do a damned thing about it, oh you can put Greta on the world coronavirus committee , really ?
