First of all this is not merit farming. The question is already answered. 
Winner:Bencus

Could you tell me what that even means? 

I will give another possibility for answer number 2.

2 - No. Bitcoin energy consumption is more a solution than a problem.

Bitcoin is mainly mined where electricity is cheap. We have cheap electricity where it's plentiful and abundant, not where it's scary.

In other words, excess energy produced is being directed to bitcoin mining. We cannot store energy, and when energy plants are build they produce more energy than required, so they can supply the region for some time.

Also,  as Bitcoin adoption grows it can hasten renewable energy development and adoption. Bitcoin mining can be an environmental subsidy to alternative energy all around the world because it's causing these projects to be amortized over a year instead of five.

It's very easy to criticize bitcoin mining because it's too obvious. More obvious than the energy consumption of Visa, for example, which not everyone is aware of how much energy they consume.

That are claims that Christmas lights consumes as much energy as bitcoin mining.

2. Adding to the other answers. The answer is: In the present Yes but in the Future not In the present because most miners take electricity from coal plants something that prior answers have been already said. In the future not. for the next reasons:

1 There are already farms in China that uses  hydroelectric power
2.There is a company called HydroMiner This established its first facility in Schönberg, Austria, which draws a base energy output of 290 kWh for its 120 mining units. Their second mining farm in Waidhofen an der Ybbs, Austria, receives a consistent supply of 600 kWh for its 250 Antmine 29s and 1152 GPUs.
3. The pollution can be comepensated by using the warmth generated to heat the water https://www.youtube.com/watch?v=9WD8OOsyZzg  Another example Qarnot QC-1 "crypto heater" takes advantage of an obvious synergy: It makes use of the waste heat generated by mining crypto in the guise of an attractive space heater.
Myera Group The heat from the miners warms the greenhouse plants, while nitrate-rich wastewater from the fish tanks keeps them watered.

1. Bitcoin mines are at where the electricity is cheap, and it does worth mining, simple as that. The cheapest power is at:
India, $0,08/kWh
China, $0,09/kWh
But this is an average, it may vary even in the country. But usually you can hear about Chinese and Russian Bitcoin farms. From these two information sources, I'd say most of the bitcoin mines are in China. At least the half.
Also, if a mining farm obtains power not from the grid, but straight from the power plant, it means cheaper power, because of bypassing plenty of fees. These fees cointain: Acquisition/sales, Grid fee, Value-added tax, Concession fees, Electricity tax, and may be others. This way, you can mine anywhere in the world, where you can get cheap enough electricity this way. Some mining companies even do this, for example Envion.
So there is no exact way/location to answer this, but to say that it can be anywhere in the world where the electricity is cheap enough.

2. Bitcoin mining's current estimated daily electricity consumption is 161913828 kWh. Yearly, that is around 59,4 TWh. That is a lot, equivalent of Columbia's electricity consumption. A country with population almost reaching 50 million.  And it is not even the biggest problem. It is not the amount of electricity needed, but where is this electricity comes from. With more then half of the mining done in China, where around 60% of the electricity is from coal, we can see that the mining is powered by electricity, produced in a dirty, polluting way.
For example, Bitmain Technologies runs a server farm in China, which runs on electricity produced in coal power plants.
It is hard to say how polluting Bitcoin production is, but I believe with merit order, it would be possible to see how much it really adds to the pollution. If we substract the power from bitcoin mining, it would be easy to see how much pollution it really creates. However this needs to be done in multiple regions, to get accurate data.
Also, acquiring the data would require some connections at the local electricity companies, so I think it would be hard for a single person to analise the pollution of Bitcoin mining.
But all in all, Bitcoin certainly uses substantial amount of energy, and undoubtedly creates immense pollution.

1.
About 1,800 new bitcoins are mined each week. It can take 1.7 billion attempts to unlock a new bitcoin. The work must be proved before a bitcoin is added to the chain. Where are the bitcoin mines?Why?

Answer: The bitcoin mines are mainly placed near cheap power sources, although somewhat less common is miners setting up in localities that subsidize power consumption or contract deals with miners directly who pay a greatly reduced rate for power. The most common areas are around hydroelectric power in China, the US and the EU.

2.
Bitcoin takes a lot of computer power to mine and to trade. It requires a lot of electricity to run those computers, which in turn generate enormous amounts of heat. Should the world be worried about pollution from the bitcoin mines?

Answer: Yes, we should be worried about the pollution generated from bitcoin miners. The difficulty level bitcoin is at and even the way mining works was not invented assuming the current massive demand for bitcoin. Literally hundreds of coins and tokens have managed to solve the pollution problem bitcoin has. The only thing stopping bitcoin is the strong centralized miners that are trying to keep fees high and maintain control and domination over the bitcoin community.

Is this question number 3?

The OP is a merit beggar. Merit farming seems to be the purpose of this exercise.

The answer to this question I guess is China. Why ? Because of abundance of Hydropower.
They banned bitcoin for a while and now ICOs .

---

The Mining is a guessing game in which the mining rig has to brute force to get bitcoin confirmed. Sure they may take a second to solve it but the attempts to crack the hash is 1.7 billion (according to op).

Yes it is. This is already proven In somewhere where bitcoins are banned by thier government due to that they get a lot of bitcoins. I won't say the place where it is. Waiting for some answers.

?  Not true at all.  Modern hardware can hash that in a second.  The average bitcoin takes 10 minutes.

Let's have some fun by answering some bitcoin stuffs.
