Bitcoin needs to consume energy to sustain itself. This necessarily involves cryptocurrencies in the discussion about environmental impact. The practice of cryptocurrency mining requires vast amounts of electrical current to power the thousands of connected computers that are running simultaneous calculations. New currencies are the reward for the first to complete the calculation. Afterwards, the transactions are confirmed and recorded in the public register of the cryptocurrencies, or Blockchain. More opportunities will have to win Bitcoin who more power is investing in it, it is for this reason that the system consumes so much energy.

It is estimated that the Bitcoin mining industry consumes between 55.63 and 73.12 TWh of electricity per year. There are between 175 and 181 countries that annually use less electricity than the Bitcoin mining industry . According to the Power Compare data   updated at the end of 2018.

In the map shown below, all countries whose annual electricity consumption exceeds 73 TWh (estimated maximum used to undermine Bitcoin) appear in black. In blue those countries whose consumption is between 73 and 55 TWh of electricity. And in yellow, countries that consume less than 55 TWh per year (estimated minimum used to undermine Bitcoin)

Mexico is listed as one of the countries that consume more energy annually than the Bitcoin mining industry; In all of Mexico in a year, approximately 238 TWh of electricity is consumed. This is about 4 times more than the energy consumed by the Bitcoin mining industry.

However, there are many countries that spend much less energy than Bitcoin. Bitcoin mining now consumes potentially more electricity than almost 10% of the world's people and there are 66 countries whose electricity consumption per capita is less than what is needed to mine 1 Bitcoin. However, in the last 10 years, Bitcoin mining has used as much energy as used by cars in the US in 3 or 4 days.

Although the total hashrate can be calculated, it is impossible to determine what this means in terms of energy consumption, since there is no central register with all active machines and their exact power consumption. The numbers provided are estimates.

In addition, it is only talking about the energy used for mining, however, for a user to buy Bitcoin, it necessarily requires being connected to sources of electricity. The energy used by Bitcoin traders and users.

China is the country that consumes the most electricity in the world: It spends approximately 6,310 TWh per year per year, this represents almost 30% of the world's electricity consumption. Last week, China published a statement about the measures that are being taken to reduce the environmental impact and within this agenda mining activities (the production of a virtual currency like Bitcoin) are mentioned as harmful to the environment, to the extent that it is considering banning the mining of Bitcoin in the Asian giant.

It is estimated that 70% of Bitcoin mining worldwide occurs in China. In addition, the most common way to obtain energy in China is through coal, a highly polluting fossil fuel. In itself the Chinese authorities have been skeptical about the use of Bitcoin repeatedly. The ban on Bitcoin mining in China could shake the industry.

Other similar cases have arisen around the world. For example, last year, in Alberta, Canada, the community surrounding a Bitcoin mining farm filed complaints with the local mayor's office, claiming that the mining farm uses the same amount of energy used in the entire town, called Medicine Hat

The way the bitcoin algorithm works is designed to spend as much electricity as possible. And the more popular bitcoin becomes, the more electricity it spends, ”said Keith Stewart, spokeswoman for Greenpeace.
The Norwegian authorities have acted on the same line. The Nordic country has implemented a plan to reduce taxes on electricity, however, it excludes the cryptocurrency mining industry from this benefit. Thus, Norway puts an end to cheap electricity for the mining sector, which depends on the energy to operate.

I feel that each of the people who make life and work with cryptocurrencies should ask each day this question:

How can the development of cryptocurrencies and Bitcoin continue without representing damage to the environment?

I found this article completely cool, we should all worry more about the damage we do every day to the planet.

The amount of electricity used is actually not much compared to other industries. Fun example is banking. Just think of all the big buildings they heat!

But as fun as this is, you have to remember that the amount of electricity used is directly proportional to the price. The price goes down, miners turn of equipment. This is why BCH only has 4% of the mining power compared to BTC. And thus only 4% of the energy cost.

On the other side, the benefit of mining is proportional to the usage. More people use this coin and the energy burned is actually useful. Would you consider the energy usefully used if all banks close their offices and turn off their very expensive super-computers?

Regardless of your opinion on either it should become clear that there is a balance between power-usage (which is directly related to price) and coin-usage (or, utility). The balance for BTC is absolutely not healthy. The utility of the coin does not warren the power burned.

When we look at the relationship of power-usage (= price) and utility we discover that the coins are today based on future usage. What people expect the value to be of the coin based on the promise the coin gives for growth. And in some cases (IMO BTC) its just pure gambling and manipulation.

The up-side of this, then, is that over time this balance will most likely become more normalized. The coin with the most utility will likely get the most valued in the market and that means it will be the one with the most mining. Which is Ok because more mining means more value generated for more people.

Bottom line: we are in a speculation cycle of this product and the power-usage is off the charts because people are speculating with the price of the currency.
