Bitcoin mining eletricity costs is about securing the network against continental scale attacks.

You cannot make a 51% attack without consuming electricity on a continental scale. This is the level of security that a decentralized global currency needs.

Nothing to do with CO2 or plants or the environment. I hope some day we have some cleaner energy, like solar or wind, but that is not the reality now and bitcoin can do nothing about it.

Bitcoin is futuristic and it needs innovative solutions for energy consumption. Solar, wind and the renewable energy source is the solution and must be accomplished soon.

Then we need to build more coal and oil fired generators on a continental scale. Miners could use their mined bitcoins to set this up. Bitcoin could become a secondary source of income for them. They could provide electricity to the world... and to their mining, of course.

The more CO2, the more plants will grow. More and cheaper food so that we can have bigger populations. Think of not having to worry any longer if your contraceptive is working this time.

Along with the CO2 produced is the production of water. If cars ran clean, they would produce two basic things, CO2 and water. Water in the atmosphere - especially the upper atmosphere - would help the ozone do its job better.

Jobs would be for the electricity producing plants. But if there was more cheaper electricity, wouldn't the miners add more mining machines?

A fossil fuel power plant can be moved anywhere. You can ship fossil fuels anywhere. But it isn't easy to redirect the course of a river, and certainly not a nuclear plant.

Solar and wind is BS. Look at what happened to Texas. If they had had fossil fuels as a backup, and if the windmills had been designed properly, they might have made it through the recent storm without any loss of life. Fossil fuels are the answer. All the hype about wind and solar is big business trying to make money off the people.

A dam breaking isn't anything like a gradual increase in fossil fuel power plant numbers. Miners have a good start at having enough Bitcoin money to build power plants and make money in two areas.

How much electricity is used for mining of gold? Massive amounts of mercury and other toxins are released in addition to wasting electricity during gold mining. And both gold and Bitcoin are having similar purpose. Why no one talks about the negative impact of gold mining, although they would like to lecture us on the usage of electricity for Bitcoin mining? Vast tracts of Amazon forest are being cut down in Brazil, Venezuela and Peru every year for the purpose of gold mining. At least Bitcoin mining doesn't require any deforestation.

Burning fossil fuels produces a lot of toxins,which are going into the atmosphere.It's not only CO2.
More CO2 into the atmosphere means global warming and global warming means unpredictable weather.
Unpredictable weather means more dry seasons,which is bad for agriculture and more powerful hurricanes,which is also bad for agriculture.
Anyway,the Bitcoin haters,that are saying that BTC mining is polluting the earth are just a bunch of hypocrites.You can't put the blame solely on BTC mining for all the pollution of the atmosphere.

This is the challenge that the Bitcoin and cryptocurrency community has to be facing. I mean we should be demanding a greener and cleaner source of energy that should be use in mining in Bitcoin...and this will surely not happen easily but should be done on a gradual basis. Rather than dismiss the whole thing as if nothing is happening, solutions has to be found and that is where innovations can come in. There are now many improvements in the area of solar, wind and other sustainable alternative power and those in Bitcoin mining can come to where the sources are to minimize expenses. Or maybe someone could come up with a better mining solution that is requiring less power.

I hope you are just playing fool, although it seems clear you are not.

CO2 does not create plants so it simply doesn't follow that since the world is producing an astounding amount of it there'd be more plants to grow. That's too ignorant of you to say the least.

Furthermore, please be informed that the poor earth's plants and trees can only absorb so much of CO2, around 25% only. The 50% stays in the atmosphere and the other 25% will be absorbed by the world's oceans. In other words, 75% of the world's CO2 will warm the earth. Only 25% is converted into food by plants and trees.


For goodness' sake!

What is C-zero-2? It's C-O-2, for carbon dioxide.

Neither does the food you eat create you. Rather, it strengthens you and sustains you. And if you are the kind of person who wants kids, it helps you to be strong in your procreation. If you are a woman who is healthy from food, your kids will be healthier from their growth inside your tummy.

We had a healthy world when the mammoths ranged the earth. Some of them froze in the great freeze, and are still being dug out of the Siberian permafrost. Let the earth get back to the warmth we once had.

When plants absorb CO2 and minerals, they become so healthy that they become much more fertile. They have kids, and there is much more CO2 for the kids to absorb. The plants that are food plants allow the human population to expand, and there is a whole lot more fun in the world with the healthy kids.

Forget all that global warming and overpopulation nonsense that some political blabber-mouths are trying to use to take over the world.

This problem is really far-fetched, but it comes up again and again. Do we have enough electricity in the world and nowhere to get it? This is the period when solar panels were invented and it is possible to relatively efficiently directly convert solar energy into electrical energy? This energy is practically clean and does not pollute the environment, and therefore we should not have any problems with its production and use, including for the production of bitcoins and other cryptocurrencies.
