Bitcoin price today: The dollar traded steady on Monday ahead of the U. Federal Reserve's January policy meeting later this week, while Bitcoin lay bruised near a six-month low hit over the weekend, hurt by a sell-off in technology stocks. Attempts to predict when and how quickly central banks will raise interest rates and conclude stimulus programmes launched when COVID hit are a major factor driving currency markets at present. The Fed's rate-setting Federal Open Market Committee kicks off its two-day meeting on Tuesday with some analysts starting to speculate that it is possible, though unlikely, that it will raise interest rates for the first time since the pandemic began. The urgency could culminate in a decision to abruptly stop quantitative easing by mid-February," said analysts at Commonwealth Bank of Australia in a note. The dollar index, which measures the greenback against six major peers was steady at

Even before millions were confined to their homes by a global pandemic, improvements in internet connections and service offerings had led to an exponential increase in the use of streaming video around the world. With few options left for entertainment, streaming services are taking off. In this commentary, we examine the carbon footprint of these services. Streaming services are associated with energy use and carbon emissions from devices, network infrastructure and data centres.
Yet, contrary to a slew of recent misleading media coverage, the climate impacts of streaming video remain relatively modest, particularly compared to other activities and sectors. Drawing on our analysis and other credible sources, we expose the flawed assumptions in one widely reported estimate of the emissions from watching 30 minutes of Netflix.
These exaggerate the actual climate impact by up 90 times. The relatively low climate impact of streaming video today is thanks to rapid improvements in the energy efficiency of data centres, networks and devices.
But slowing efficiency gains, rebound effects and new demands from emerging technologies, including artificial intelligence AI and blockchain , raise increasing concerns about the overall environmental impacts of the sector over the coming decades.
As a result, the central IEA estimate for one hour of streaming video in is now 36gCO2, down from 82gCO2 in the original analysis published in February The updated charts and comparisons also include the corrected values published by The Shift Project in June , as well as other recent estimates quoted by the media.
The report said streaming was responsible for more than m tonnes of CO2 MtCO2 in , equivalent to emissions from France. That study found streaming in the US in emitted 0. Emissions from operations — comparable in scope to the Shift Project analysis — accounted for only 0. However, because the energy efficiency of data centres and networks is improving rapidly — doubling every couple of years — energy use and emissions from streaming today should be substantially lower.
Looking at electricity consumption alone, the original Shift Project figures imply that one hour of Netflix consumes 6. This is enough to drive a Tesla Model S more than 30km , power an LED lightbulb constantly for a month, or boil a kettle once a day for nearly three months.
The corrected figures imply that one hour of Netflix consumes 0. With million Netflix subscribers watching an average of two hours per day , the corrected Shift Project figures imply that Netflix streaming consumes around 94 terawatt hours TWh per year, which is times larger than figures reported by Netflix 0. At this rate, YouTube — with over 1 billion viewing hours a day — would consume over TWh a year 2.
The assumptions behind the Shift Project analysis largely based on a paper , whose assumptions have been significantly revised in and contain a series of flaws, which, taken together, seriously exaggerate the electricity consumed by streaming video. This was six times higher than the global average bitrate for Netflix in around 4.
This difference stemmed from a stated assumption of 3Mbps apparently being converted in error to 3 megabytes per second, MBps, with each byte equivalent to eight bits. The Shift Project corrected this error in their June update , but did not revise any of their other assumptions, discussed below. The chart below shows each of three ways that the Shift Project overestimated electricity use for streaming video — such as the bitrate — and one area where it underestimated the actual figure.
These other errors are described in the text below the chart. The Shift Project analysis overestimates the energy intensity of data centres and content delivery networks CDNs that serve streaming video to consumers by around fold, relative to figures derived from Netflix electricity consumption data and subscriber usage data. My updated analysis shows the Shift Project also overestimates the energy intensity of data transmission networks by around fold, based on average bitrates for streaming video.
This is the result of using high and outdated energy-use assumptions for various access modes — for example, 0. My original February analysis showed that the Shift Project assumptions for data transmission energy intensity 0.
Instead, experts advise using time-based energy intensity values kWh per viewing hour. Therefore, my assumptions for data transmission energy use have been updated with time-based energy intensity values. Taken together, my updated analysis suggests that streaming a Netflix video in typically consumed around 0. The results are highly sensitive to the choice of viewing device, type of network connection and resolution, as shown in the chart, below right.
For example, a inch LED television consumes much more electricity than a smartphone times or laptop 5 times. The carbon footprint of streaming video depends first on the electricity usage, set out above, and then on the CO2 emissions associated with each unit of electricity generation.
As with other electricity end-uses, such as electric vehicles , this means that the overall footprint of streaming video depends most heavily on how the electricity is generated. Powered by the global average electricity mix , streaming a minute show on Netflix in released around 0. This is around times less than the original 1. My estimate of 36gCO2 per hour is over times lower than Marks et al. To put it in context, my updated estimate for the average carbon footprint of a half-hour Netflix show is equivalent to driving around metres in a conventional car.
But as the chart above shows, this figure depends heavily on the generation mix of the country in question. Using country average emission factors may still overestimate emissions, particularly from data centres. Technology firms operating large data centres are leaders in corporate procurement of clean energy, accounting for about half of renewable power purchase agreements in recent years. The electricity mix is also rapidly decarbonising in many parts of the world.
Compared to levels , global emissions intensity of electricity falls by around a quarter by in the IEA Stated Policies Scenario and by half in the Sustainable Development Scenario. Although the carbon footprint of streaming video remains relatively modest, it might still seem reasonable to expect the overall impact to rise, given exponential increases in usage. This law describes trends in the energy efficiency of computing, which has doubled roughly every 1.
A similar trend has been observed in data transmission networks, with energy intensity halving every two years since Coupled with the short lifespans of devices and equipment, which hastens turnover, the efficiency of the overall stock of devices, data centres and networks is improving rapidly. As well as changes that are invisible to the consumer, there are also obvious trends in the technology seen everyday.
Devices are also becoming smaller and more efficient , for example, in shifts from CRT to LCD screens, and from personal computers to tablets and smartphones. Set against all this is the fact that consumption of streaming media is growing rapidly. Many new video streaming and cloud gaming services have also launched in recent months. The ease of accessing streaming media is leading to a large rebound effect , with overall streaming video consumption rising rapidly.
But the complexity of direct and indirect effects of digital services , such as streaming video, e-books, and online shopping, make it immensely challenging to quantify the net environmental impacts, relative to alternative forms of consumption.
Moreover, emerging digital technologies, such as machine learning , blockchain , 5G , and virtual reality , are likely to further accelerate demand for data centre and network services.
Researchers have started to study the potential energy and emissions impacts of these technologies, including blockchain and machine learning. It is becoming increasingly likely that efficiency gains of current technologies may be unable to keep pace with this growing data demand. Streaming video is a fairly low-emitting activity, especially compared to driving to a cinema, for instance. As consumers, we can further reduce our environmental footprint by using smaller devices and screens, which consume less electricity.
Much less data-intensive digital activities such as e-mail have also drawn significant and misleading media attention regarding their carbon footprint. Recent headlines in the Financial Times , the Guardian , and Bloomberg Green have suggested that cutting back on e-mails could lead to substantial emission reductions — over 16, tonnes per year in the UK if every adult sent one less unnecessary e-mail per day.
These claims are based on analysis by OVO Energy which assume that one unnecessary e-mail emits 1gCO2, which come from back-of-the-envelope calculations from 10 years ago. In reality, emissions from e-mails today are much lower, and experts have explained how and why these headlines vastly overestimate the potential emission reductions from avoided emails.
Technology companies can continue to play a big role in reducing the environmental impact of streaming, including through further efforts to increase energy efficiency — both in the near-term with new technologies and through developing next-generation technologies — and investing in renewable energy to power their data centres and networks. Sustainable design and coding could also help, such as further improving video compression.
A recent study explored the potential energy and emission reductions of shifting YouTube music videos to audio only when playing in the background. It is important to keep in mind the scale of emissions from digital technologies compared to other sectors, with digital technologies accounting for around 1. All sectors and technologies are needed to help achieve the goals of the Paris Agreement and digital technologies are no exception.
In fact, digital technologies, such as AI, could help accelerate climate action. But without sound climate policies, AI could end up just helping to make oil extraction cheaper or extending the lifetime of coal plants. What is indisputable is the need to keep a close eye on the explosive growth of Netflix and other digital technologies and services to ensure society is receiving maximum benefits, while minimising the negative consequences — including on electricity use and carbon emissions.
Instead of relying on misleading media coverage, this will require rigorous analysis, corporate leadership, sound policy and informed citizens. The analysis of the carbon intensity of streaming video presented in this piece is based on a range of sources and assumptions, calculated for or the latest year possible.
This analysis was updated to include new data on viewing hours and new research on the energy use characteristics of data transmission networks at high bitrates, as well as the revised estimate from the Shift Project published in June The update also adds comparisons to other estimates widely quoted in the media.

It is clear that these figures are too high — but by how much? Bitrate: global weighted average calculated based on subscriptions by country and average country-level data streaming rates from Netflix in ; resolution-specific bitrates from Netflix.
Note: the calculated global weighted average is a slightly conservative assumption, since the country-level bitrate data excludes streaming via cellular networks , which typically have lower bitrates. Data centres: based on Netflix reported direct and indirect electricity consumption in , the number of subscribers as of the end of and their average viewing habits and global weighted average bitrate above.
Note: this assumption is also conservative, since the reported Netflix electricity consumption data includes electricity use from studios and offices, which should ideally be excluded when calculating emissions from streaming. Data transmission networks: time-based energy intensity values kWh per hour based on emerging research from Malmodin According to Malmodin, data-based energy intensity assumptions kWh per GB used previously are not suitable for high bitrate applications such as streaming video.
Devices: smartphones and tablets: calculations based on Urban et al. Note: due to a lack of usage data, these assumptions do not include energy use from set-top-boxes and gaming consoles which some TV viewers may be using.
As a result, these figures likely slightly underestimate overall device energy use from streaming. Carbon intensity of electricity: based on IEA country-level and global data. Subscription successful Close dialog.
Finder co-founder Fred Schebesta predicts Bitcoin will recover to be worth $100,000 by end of 2022
Since the launch of Bitcoin in , the world of cryptocurrencies has grown larger and more popular, particularly in recent years. There has been an increase in the usage and acceptance of virtual currencies alongside a growing number of tokens and investors. However, with the increase in prominence has also come higher incidence of thefts, fraud and hacking. Since the regulatory framework of virtual currencies remains murky, there is often no recourse for owners in case of fraud or theft.

‘I Forgot My PIN’: An Epic Tale of Losing $30,000 in Bitcoin
After its launch in early , Bitcoin has gone through a lot of ups and downs. Some of its biggest price swings were in and , when a steep rise followed by an 84 percent decline brought plenty of hype and headlines. Not surprisingly, more and more investors are now jumping on what can still seem like a techy, trendy bandwagon. In an economy where governments are printing money hand over fist, people want a more secure place to put their assets. In addition to prevailing economic uncertainty, many institutional investors are dipping their toes into the cryptocurrency, and even PayPal began offering customers the ability to buy Bitcoin late last year. Some even believe digital currencies like Bitcoin are the future of money.

RELATED VIDEO: NEXT WEEK IS BITCOIN'S BEGINNING OF THE END!!! BEWARE…One of Australia's richest young millionaires is predicting Bitcoin will double within a year - despite a recent price crash. But the climb will be volatile, with prices dipping up and down along the way. Schebesta, who last year ranked 29 on the Australian Financial Review's Young Rich List, told Daily Mail Australia: 'Bitcoin is in a phase of correction and this could last for the rest of the year as it settles into more stability. He is so confident that he is investing in a platform that lets investors earn cryptocurrencies by playing video games. The current Bitcoin downturn is occurring despite a surge in inflation across the rich world, with American consumer prices climbing by 7 per cent in - marking the fastest increase in four decades. New Zealand's consumer price index in the year to December rose by 5.
