You really think that Bitcoin is to blame for the fires in the Amazon or Australia, or for the snow not falling in the winter like it used to? More than once in this forum, the thesis about Bitcoin as the cause of the problem has been taken down to the ground. More than 2 thirds of the energy used for mining comes from renewable sources, mainly hydropower. I don't know what more the crypto community should do to prevent global warming or all the catastrophes happening in the world, they are the consequence of what began after WW II, and the consequences are visible today, the progress and civilization we have today have their price.

Good post to see how insignificant the impact of Bitcoin mining really is.

Omg it's completely hilarious how you interpreted this , it's like how we could as a community make bitcoins environment friendly and self sustainable .
You think Bitcoiners went and lit the fire is what I meant?
Dude , every step counts !
EVERY !
Wether it's growing the community in a greener way or looking for other sources ..
Please take an account of what you really think people mean and what they actually mean .

Unfortunately the source you stated is something I already read , you should understand that different scientists and different forums are displaying a different result everywhere

For example :-

Depending on the energy source, researchers estimate that crypto-mining can produce 3-15 million tons of global carbon emissions.


This !
It's an estimate but one should understand that countries like China and others where the mining hub is located are not using the renewable sources that much .
People are doing it illegally in developing countries too , it's not as easy as you would read.

1. mining is already becoming more sustainable. the hashrate/watt is getting more efficient all the time. imagine hashing 100exahash using GPU and you will see that if we didnt develop ASICS the electric use would be much much much much(not exaggerating) higher
take for instance 9GPU rig vs a antminer s9 . (same electric use)
900mhash(gpu) vs 14thash
yep ASIC is 15,555x more efficient than GPU

2. bushfires are not caused by mining... if it was then china and georgia would be on fire. not the amazon/australia.
the reason the amazon and australia burn is due to the lack of water. carbon is a lung health issue because the 'greenhousegas' actually shows the upper atmosphere is cooling. yep its cooling. heat rises and more is getting released into the atmosphere rather than being reflected back in.. because the greenhouse affect is not reflecting much back.... at ground level the reason why not as much heat is getting evaporated into the air is lack of water. yep the water cycle has more problems than carbon.

3. snow at christmas... i think you have been watching too much cocacola adverts and fairy tale books making people think they remember snow at christmas every year.. truth is snow is more of a february period.
in england we have historical data that in the last 60 years we only had 9 times of a white christmas but many more of a white february. even things like the london 'frost fair' in the 1800's was in february.
what you find out is things like the cartoon 'the snowman' (nothing to do with christmas the author says) is featured on tv at christmas. even things like the movies 'frozen' 1&2.(again nothing to do with christmas) are released around the november/december period.
did you know most christmas movies are not filmed at christmas. but filmed using fake snow and people celebrating christ while outside the studio its summer. yep snow on TV is usually fake snow.. paper mache

...
summary. dont take media's opinion on how things are. actually do the math find the stats and actually really think about whats being presented to you

I agree with you that every step counts, but Lucius and the post of mine he quoted are still accurate. Bitcoin is a tiny proportion of global energy usage. If you somehow managed to make bitcoin 99% more efficient, you would still have saved far less electricity than if you made TVs (or cable boxes, or computers, or light bulbs, etc.) 1% more efficient.

Again, a tiny fraction. Based on the research I have seen, even the higher figure of 15 millions tonnes of CO₂ is total current emissions from cryptomining, so works out at less than 3 million tonnes per year. Global CO₂ emissions are currently over 40 billion tonnes per year, meaning cryptocurrency is less than 0.01%. For comparison, console gaming (not including mobile or PC gaming), accounts for 30 million tonnes per year, and streaming online porn accounts for 100 million tonnes per year. If everyone in the world watched 3% less porn than they currently watch, it would offset the entire bitcoin network and more.

Electricity is the most important problem for making mining sustainable. Electricity consumption is already a general problem. Bitcoin mining needs to be done with renewable energy sources. Bitcoin production is also very expensive equipment.

It's a noble thought! Even though bitcoin mining uses a very small fraction of world energy consumption, but we need to start taking baby steps! I believe the only way to make bitcoin mining sustainable and to reduce carbon emission, is to move to alternative energy source. So solar power is a very good alternative for all small bitcoin miners. Yes, it is expensive but also it is a one time cost! Usually each solar panel comes with 10 years lifetime so the investment towards solar panel also gets a bigger payback period. As of now, I don't see any other viable options to make mining sustainable. let me know your thoughts!

Well if anyone sticks on these “it is better than it was” “others do worst” kind of arguments we are in bad shape.
As a mother, I use bitcoin because I think it will bring a better world to my children.
At the same time, as an engineer, my opinion is that it will be an epic failure if such hashpower can’t do more than just secure bitcoin blockchain.

I also think that Mining for Bitcoin will not last long it has an end after the last block had been mine all mining procedures will also come to a halt, but not to mention the past mining that had to happen and it already contributed to the population and I think it is already too late the damage had been done,

But in my opinion, don't blame it all in the mining of the block there are much bigger things that make the environment and our world into global warming and I think we can sure focus on that because I truly think that mining is just a small portion of that problem so just chill.

To reduce the footprint we should first get to consensus on where it currently stands. I agree that it's important to help our environment and that the beginning of the year already shows the serious consequences of previous policies. The problem is that I've seen conflicting research about Bitcoin mining's impact on the environment. There's been data saying that it's mostly clean energy that's used, and some suggest quite the opposite. So which one is it?
Secondly, it's, unfortunately, something very hard to control. I  don't mine, so I'm not a part of it, but when I use electricity in a flat I rent (or even when those who own flats in my country do that), it's not up to me what is the source of that energy and how clean it is. It's up to the government. So how can this be changed by miners?
