In today's fierce competition for digital currency mining, Bitcoin's mining index has always been the focus of investors and miners. However, a recent study by the University of Cambridge has caused a sensation: idle household appliances in the United States can actually provide energy support for Bitcoin for many years! This innovative discovery not only reveals new possibilities for energy utilization, but also triggers people's in-depth thinking about Bitcoin mining and energy sustainability.

In the United States, a large number of household appliances are idle or scrapped every year for various reasons. These include washing machines, refrigerators, microwave ovens and other household appliances. These idle household appliances are often regarded as waste in traditional concepts and need to be recycled or scrapped. However, the research team at the University of Cambridge found that these seemingly abandoned household appliances actually contain huge energy potential and can provide long-term and stable power support for Bitcoin mining.

The Bitcoin mining process requires a lot of power support, and traditional mines often consume a lot of fossil energy, which puts great pressure on the environment. However, by utilizing idle household appliances, energy reuse and recycling can be achieved, which can not only reduce mining costs, but also reduce negative impacts on the environment. This innovative way of energy utilization can not only provide more stable and sustainable energy support for Bitcoin mining, but also provide new ideas for environmental protection and resource conservation.

In practical applications, by transforming and optimizing idle household appliances, they can be converted into energy equipment for Bitcoin mining. For example, a discarded washing machine can be transformed into a mining device that can provide stable electricity, or a discarded refrigerator can be used as an energy storage device. This innovative way of energy utilization can not only reduce mining costs, but also improve energy utilization efficiency and maximize resource utilization.

In addition to providing energy support for Bitcoin mining, energy recycling using idle household appliances can also save energy costs for families and reduce household energy consumption. By converting discarded household appliances into energy equipment, it can not only provide support for Bitcoin mining, but also realize energy recycling and contribute to environmental protection. This innovative way of energy utilization can not only bring economic benefits, but also promote energy sustainable development and achieve a win-win situation of economic and environmental benefits.

In general, the innovative discovery that idle household appliances in the United States have provided energy support for Bitcoin for many years not only reveals new possibilities for energy utilization, but also proposes a new solution for Bitcoin mining and energy sustainability. By recycling energy from idle home appliances, we can not only provide stable power support for Bitcoin mining, but also achieve energy reuse and recycling, and promote sustainable energy development. This innovative way of energy utilization can not only bring economic benefits, but also contribute to environmental protection, achieving a win-win situation for economic and environmental benefits. Let us look forward to using idle home appliances to bring more innovations and possibilities to Bitcoin mining, and make greater contributions to the development of the energy field in the future.

The issue of energy consumption in the Bitcoin network has long been a point of contention between loyal supporters and critics. The most cited data from Digiconomist states that if Bitcoin were a country, the network consumes as much energy as Colombia each year, making it the 42nd largest energy consumer in the world.

Meanwhile, a report from Coinshares made a claim about this figure, saying that the vast majority of the energy is produced by renewable energy.

The Cambridge Center for Alternative Finance, a research institute under the Cambridge Business School of the University of Cambridge, released the CBECI (Cambridge Bitcoin Electricity Consumption Index) index yesterday, which aims to count the total annual electricity consumption of the Bitcoin network in real time.

The CBECI counts the total energy consumption of the Bitcoin network each year, updated every 30 seconds. The researchers also provide a tool to compare Bitcoin's electricity consumption levels with other electricity use cases, and provide a range of parameters to provide more comprehensive real-time data.

As of press time, the CBECI estimates the Bitcoin mining electricity data to be 7.57 gigawatts (GW), with an estimated average annual consumption of 53.01 terawatt hours (TWh).

Crypto enthusiasts on Twitter have noted some interesting metrics from the CBECI, such as the fact that in the US alone, the amount of electricity wasted each year by leaving household devices on but not used could power the Bitcoin network for four years.

In addition, the amount of electricity consumed by the Bitcoin network in a year could power all the kettles in the UK for 11 years, and 1.5 years in Europe.

According to CBECI estimates, Bitcoin mining accounts for about 0.24% of the world's total electricity consumption each year (20,863
TWh). A chart comparing the Bitcoin network to the total electricity consumption of nation states around the world shows that Bitcoin ranks 43rd among the world's "countries", consuming more electricity than many countries including Romania, Denmark, Israel, Singapore and Uzbekistan.

The Cambridge Center for Alternative Finance noted that the purpose of creating the index is to provide objective, neutral data for use by policymakers, regulators, researchers and stakeholders, and to help debate around the sustainability and environmental impact of Bitcoin mining.

The agency said that so far, there are few reliable statistics on Bitcoin's electricity consumption, as most institutions only provide lagging data, so a more comprehensive analysis of the crypto industry's carbon emissions is needed.

It is reported that in the next stage, the index will provide a global mining equipment distribution map.
