Energy isn't scarce, its actually abundant. At this particular moment, clean renewable energy capacity is more scarce than fossil fuel, but there is simply far more potential energy in solar, wind, nuclear, etc. Remember, our planet is bombarded by solar rays 24/7 and will continue to receive this energy for billions of years. Human energy consumption has been exponential over time. We started by harvesting crops wit…

I too enjoy whataboutism to distract folks from the environmental impact of my favorite Ponzi scheme. > Do those things, and Bitcoin will literally subsidize and accelerate clean energy infrastructure investment. If you invest in massive solar and wind plants then use that energy to roll rocks up and back down a hill forever like Sisyphus, that's jus…

It's a waste to you, but not to the people who use and value it.

With a climate crisis the last thing we needed was to make the most effective energy consumption system ever constructed. The whole thing literally works on competing on consuming more energy. No other system works so efficiently towards such goal. What's scary is that the whole thing was designed to be unstoppable. My utopian hope for the future is that we start sending rigs in orbit close to the sun. Since we only…

> What's scary is that the whole thing was designed to be unstoppable. It’s only unstoppable within the game theoretic model of crypto itself, not within the larger societal context. Once Bitcoin power consumption enters the common discourse, my guess is that politicians will step in and simply outlaw PoW systems. There is no real downside for politicians. The average voter hasn’t yet invested their life savings into…

Yes, it is a classic tragedy of the commons situation, and that is what politics - collective action - is good at fixing (at least sometimes).

The worst part is that according to Cambridge some 40% of that is coal power [1]. Frequently the dirtiest coal power in the world, between Xinjiang (no longer, probably...) and Kazakhstan. Coal power causes excess mortality of anywhere between 25 and 278 deaths per TWh generated depending on how you're counting it and (most importantly) where it's generated.

You really think that China banning bitcoin means they no longer use those dirty coal power plants? For a country that has such a huge demand for power that it's had blackouts and struggled to keep businesses powered even AFTER they banned all bitcoin mining[1]? Maybe that might even have to do with why they banned it in the first place? It sucks that bitcoin uses so much power, but these countries using fossil fuels…

> You really think that China banning bitcoin means they no longer use those dirty coal power plants?

No, but banning the miners meant they didn't have to build a whole pile more.

"Heartbreaking: The Worst Person You Know Just Made A Great Point" - they have the moral high-ground on this issue.

> Right now China has only promised to reduce its fossil fuel to 20% of its total energy use by 2060.

Sure. And it would have been a smaller reduction had they not kicked out the miners. This waste is purely additive.

Just copying another comment abotu the energy consumption of online adverising "The online advertising ecosystem resides in the core of the Internet, and it is the sole source of funding for many online services. Therefore, it is an essential factor in the analysis of the Internet's energy footprint. As a result, in 2016, online advertising consumed 20–282 TWh of energy. In the same year, the total infrastructure con…

Yes but if we start playing the “which energy use is more valid” game then quickly we realize energy is in the eye of the beholder, and the solution is a pollution tax. Bitcoin shouldn’t be outlawed anymore than video games (a totally useless tech from a society viewpoint) but HNers love their video games and Google paychecks.

> In a few years Bitcoin mining will kill way more people than the number of political dissidents How are you counting the number of political dissidents saved?

Do you have any evidence that this number is nonzero?

There's none. It's mind boggling that 12 years later, people like the parent poster are still claiming bullshit like that when there's literally zero evidence, rather the opposite. No country with underdeveloped banking and payment systems is interested in something like Bitcoin. They need something cheap and efficient, federated and... centralized! Many African countries are perfectly fine using M-Pesa.

Interesting article. Thanks for sharing.

> DePaul University suggests that this number should be closer to 35 tons of CO2 for jewelry, which accounts for roughly 50% of global gold demand. It is assumed that refinement uses a similar amount of power to recycling; therefore, a total of 79.9 MWh is used for the mining and refinement of each gram of gold used in jewelry. Each kilogram of recycled gold produces 37 tons of CO2 and uses 31.3 MWh of energy. This b…

transactions on bitcoin cost basically 0 energy too. the bitcoin energy expenditure is from block creation, which is independent from transactions. Of course, bitcoin transactions incentivize block creation, but gold transactions also incentivize gold mining to some degree.

Bitcoin energy expenditure is not entirely independent from block creation. Transaction fees already make up a nontrivial fraction of the block reward and can be expected to dominate block subsidy within a few decades as the latter keeps halving every 4 years.

I have a son who is just about 10 years old, and he’s getting to the age where he’s beginning to realize how irrational our world is. We recently had a conversation discussing the fact that we could eradicate hunger and the need for clean water globally, but for a whole host of reasons we have not yet done it. He continues to probe “why“ and all I can say is, essentially, because people are greedy and unmotivated gen…

If you give food to poor areas for free then their farmers go out of business, the area becomes more poor, and they become dependent on aid. Breaking systems always has consequences. It’s not easy.

How about industrialized nations get rid of their agricultural subsidies?

Slightly tangential question: Couldn't Bitcoin be implemented on something other Blockchain, since Blockchain is so computationally intensive. Like why not use a SQL database instead. It's definitely not technically infeasible, and you can reliably achieve all objectives of Bitcoin by doing so.

The idea of independent financial system is great, but the inefficiency of it's usage is something I am very doubtful about.
