For the last time, Nicholas emphasized that you must create a wallet before going on the mainnet, otherwise your Pi coins will not be transferred to the mainnet, the top priority! After digging for so long, you must not be careless. It is recommended to use your wallet to transfer coins to Pioneer every day, so that the core team thinks you are a real person, not a robot.

Original Nicholas: They will create, don’t worry. We will make the interface easier so that they create their wallets. But if someone doesn’t create a wallet then they cannot receive mainnet Pi at all. People need a wallet to access their pi.

Translation: Pi Network didn’t have to pay attention to creating a wallet. We will simplify the interface so that they can create a wallet. However, if someone does not create a wallet, then they will not be able to get the mainnet Pi at all. People need a wallet to access other people’s Pi.

We know that according to the Pai’s white paper, the current development process has entered the final stage, which is also the sprint stage, and it is also a very critical stage. The project team is very cautious about this! So there is no time to create a wallet.

Currently, pi network has announced more than 18 million active miners. This does not include those who are inactive, registered, and those who spend three days fishing on the net for two days. For a platform that has only been developed for two years to get such amazing data, it is simply a creation of God! How many internet platforms dream of results! Therefore, the project party has completed more than 90% of the progress in the second phase, which means that the entire project of π has been completed more than 95%. As for the third stage of the mainnet online site, it is very simple. So the majority of Pi friends start to get excited, the Pi coins we dig can be cashed out soon! The development trend of the blockchain has been unstoppable. Similarly, the development of pinetwork cannot be stopped. This is the general trend and the inevitable development of the times! There are more than 200 days left on the main net, and at least six coins are mined every day. In case the global barter consensus price of 100 dollars is reached after the main net is on the main net, it is equivalent to making 600 dollars a day. Because of the consensus on the source of currency value, since the current consensus is 100 US dollars, the value of each Pi after the mainnet is 100 US dollars, don’t miss it!

On May 28, the Metrology and Testing Center of the Fifth Electronics Research Institute of the Ministry of Industry and Information Technology (Guangzhou Saibao Metrology and Testing Center) released “The Road to Decarbonization of China’s Digital Infrastructure: Data Center and 5G Carbon Reduction Potential and Challenges (2020-2035) )” report (referred to as the “Report”), which predicts the energy consumption and carbon emission trends of China’s data centers and 5G and other digital infrastructures.

The “Report” states that After China fully achieves its carbon peak in 2030, the carbon emissions of digital infrastructure will continue to grow, and it has become a new growth point in energy consumption and carbon emissions. It is necessary to accelerate the transition to 100% renewable energy and achieve carbon neutrality as soon as possible.

“Report” predicts, By 2035, the total power consumption of China’s data centers and 5G will be about 2.5-3 times that of 2020 , Will reach 6,951-7,82 billion kilowatt-hours, accounting for 5-7% of China’s total electricity consumption.

Simultaneously, In 2035, the total carbon emissions of China’s data centers and 5G will reach 230-310 million tons, accounting for 2-4% of China’s carbon emissions, which is equivalent to the current carbon dioxide emissions of the two Beijing cities. Among them, the carbon emissions of data centers will increase by 103% compared with 2020, and the carbon emissions of 5G will increase by 321%.

In contrast, key emission industries such as steel, building materials, and non-ferrous metals are expected to take the lead in achieving peak carbon emissions and begin to decline after 2025, and the “lock-in effect” of carbon emissions from digital infrastructure will enable China to achieve carbon peaks and further carbon neutrality. Important challenge.

The “Report” recommends, Accelerating the transition to 100% renewable energy can fundamentally help the digital infrastructure industry to reduce carbon emissions, and is the industry’s priority path towards carbon neutrality. Among them, data centers and 5G can apply renewable energy through investment in the construction of distributed and centralized renewable energy projects, market-based procurement of renewable energy, and subscription of green power certificates, while exploring the application scenarios of combining energy storage and renewable energy. .

To this end, the “Report” puts forward the following recommendations to relevant companies: First, set a goal to achieve 100% renewable energy by 2030, and further propose a full range (scope 1, 2, 3) carbon neutral goal by 2030; The second is to expand the scale of corporate renewable energy procurement and actively communicate with key stakeholders to facilitate further breakthroughs in the market-based renewable energy procurement mechanism; the third is to further improve energy information disclosure, disclosing information on greenhouse gas emissions and energy use.

Clarification from Brinkhaus Petrol is also becoming more expensive with the Union

Status: 11.06.2021 10:40 a.m.

When it comes to the issue of gasoline prices, the focus is on the Greens. The grand coalition decided to increase the price of CO2 a long time ago. Union faction leader Brinkhaus made this clear again, but demanded an appropriate transition period. In the dispute over rising gasoline prices, Union parliamentary group leader Ralph Brinkhaus has made it clear that gasoline would also become more expensive with the Union at the head of the future federal government. “Petrol is getting more expensive, now a little bit, in the second half of this decade it will be really more expensive,” said the CDU politician in Im ARD morning magazine . This was already decided in autumn 2019. “The fight against climate change will not be for free.”

Not the “if”, but the “when” is up for debate

It is important to create realistic and fair transition periods. Germans do not have to sell their cars immediately, but they do have to be prepared to switch to electric cars or low-consumption cars in the future. The social question is not that gasoline will become more expensive. “But the social question is: Do people have a transition period that is long enough to adapt,” said Brinkhaus. This applies not only to gasoline, but also to heating. The plan is to absorb the rising prices through subsidy programs.

Gasoline price hike long been a done deal

In the debate about higher fuel prices, government spokesman Steffen Seibert had recently made it clear that the prices for fuels such as gasoline and diesel would rise in the coming years anyway. The federal government has decided to scale the CO2 price up to 2025, which already has “effects on all fuel prices”, said Seibert last Friday. This applies equally to gasoline, diesel and heating oil. The background to the statements: The coalition of the Union and the SPD had introduced CO2 pricing in traffic and buildings as a central measure in the fight against climate change. Since the beginning of the year, the CO2 price has been 25 euros per ton. According to previous plans, it should rise to 55 euros by 2025. According to calculations, this would mean a surcharge of at least 15.5 cents for a liter of petrol and at least 17.4 cents for a liter of diesel.

Baerbock’s advance fueled debate

In line with the new climate goals of the federal government, the Greens are calling for the increase to be brought forward and for the CO2 price to be raised to 60 euros per ton as early as 2023. At the same time, they propose to give back 75 euros each from the state revenue from the CO2 price to the citizens in order to avoid social upheaval. Most recently, the Green Chancellor candidate Annalena Baerbock fueled the debate. According to her party’s draft program, she advocated a gasoline price increase of 16 cents and, after her announcement, received a lot of criticism, especially from the ranks of the SPD. CSU General Secretary Markus Blume also accused the Greens of proceeding ideologically in the climate debate. “For Annalena Baerbock, climate protection is above all a fight against drivers,” Blume told the media. Mobility shouldn’t be a luxury. Rural areas and commuters will not be allowed to bear the burden unilaterally.

A clear majority rejects gasoline price increases

Environmental groups have long accused the parties of “dishonest election campaigns at the expense of the climate and biodiversity” and argued that the German government itself initiated the price of CO2, which is already making fuel more expensive and will continue to make it more expensive. The opinion of the Germans is pretty clear: According to the latest GermanyTrend three quarters (75 percent) of Germans reject a gasoline price increase. 22 percent think such a measure is a step in the right direction. A switch from internal combustion engines to electric drives in cars is also rejected by 57 percent. 37 percent would support such a measure.

Politicians and businessmen acknowledge the need to transition to a low-carbon society, but slowing global warming and meeting global goals of reducing emissions is increasingly so difficult. According to the director of the International Center for Environmental Law Carroll Muffett, the energy transition is going too slowly from a climate change perspective, but most importantly the acknowledgment of the problem is mainly willpower. political and economic options. World leaders and business sectors repeatedly reiterate their commitment to “transform the energy”. Nearly 200 countries have ratified the Paris Agreement on Climate Change, unanimously pursuing efforts to limit global warming to 1.5 degrees Celsius. This continues to be the main focus of COP26, albeit one Some climate change scientists say that now this goal has been “unattainable”. The Intergovernmental Panel on Climate Change (IPCC) thinks that between 2030 and 2052, the global temperature will get 1.5 degrees C hotter; To reduce global warming, it is necessary to reduce carbon emissions by 45% by 2030 from 2010 levels, before reaching net zero emissions by 2050. The problem is not that there is no technology or the ability to transform, or economic choice, but the structure of power and support for an industry that will decline. The emissions balancing strategies of some Governments and companies still depend on the increasing use of fossil fuels in the “coming decades”. According to Carroll Muffett, this reality can be seen in US policy, particularly in the plan to invest heavily in carbon capture and capture. The road is bumpy ahead . According to the US National Oceanic and Atmospheric Administration, the Earth’s carbon level is higher than at any time in the past 3.6 million years; If the worst effects of climate change are to be mitigated, it is important to focus on reducing fossil fuel emissions and studying how to prevent greenhouse gases entering the atmosphere. Burning fossil fuels such as oil, gas and coal releases large amounts of carbon into the air. Fossil fuel emissions and industry accounted for 89% of global emissions in 2018, the IPCC says. The US Energy Information Administration projects that global carbon emissions from fuel sources will continue to increase over the coming decades. According to energy finance analyst Clark William Derry, the current “energy transition” process is like the “transition of energy systems from the 19th century to the 21st century”; transition is taking place but it is not clear whether it is fast enough to prevent the worst consequences of climate change, fast enough to improve air quality in cities in developing countries such as in India, China, Bangladesh, Vietnam as well as some other countries; The road ahead is very bumpy. Is the current essential issue . The IPCC Intergovernmental Group notes that the transition from fossil fuels is underway and will require “rapid, far-reaching and unprecedented” changes in all aspects of the commune. festival. However, the February 2021 United Nations report showed that countries’ commitment to reducing greenhouse gas emissions was “far from” compared to the far-reaching measures needed to avoid the dire consequences of Climate Change. Currently only 75/195 countries have signed the Paris Agreement on climate change, submitting the National Contribution Plan (NDC) on emissions reductions to 2030. USA, China and India, are emissions countries. The world’s largest has yet to release its own NDC. United Nations Executive Secretary on Climate Change Patricia Espinosa urged policymakers to “accelerate” ambitious plans to cut emissions by 2021, emphasizing it as “crucial. ” The current./.

Solar power is Qatar’s strength

Huge solar power potential

Qatar and the GCC countries have the highest potential for harnessing solar energy, based on the annual amount of sunshine (including hours of sunshine and solar intensity). Not to mention, July, August and September every year is the time when the whole region has the highest amount of electricity consumption, due to the very high demand for air conditioning and also a strong solar irradiation time most of the year.

Therefore, the development of solar power technology is the most promising energy sector for Qatar. In early 2020, Qatar announced it would build a solar power plant with a peak capacity of 800 MW at Al Kharsaah, comprising 2 million two-sided photovoltaic modules (Bifacial technology) combined with tracking equipment. width over 1,000 hectares. Al-Kharsaah solar power plant will be built on 10km2 near the capital Doha, expected to be completed in 2022.

The Al-Kharsaah Solar Power Plant will reach maximum capacity when solar radiation peaks at noon – the time when the demand for electricity is highest during the day. With a two-sided photovoltaic module system incorporating a monitoring device to align the angle of sunlight absorption, the correlation between solar power production and electricity demand will be strengthened.

Total Energy (France) and Marubeni Trade and Investment (Japan) will sponsor the Al-Kharsaah Solar Power Plant Project, with a total investment of about 500 million USD (ie 0, USD 6 / Wp for Bifacial technology with tracker). This figure shows that the solar energy sector is on a constant and relentless trend of cost reduction. With the use of monitoring devices with a two-sided module, the load factor of a solar power plant can exceed 30% – an exceptionally high level in the solar sector, due to the home load factor. Average solar power in the world is only about 20%.

Fresh water is Qatar’s big problem in climate change

Electricity and water – Two main concerns

Solar PV can play a central role in meeting the growing demand for electricity and water in Qatar, as the two sectors are interrelated (large gas thermal power plants can produce water from desalination). However, the demand for water and electricity in summer is very high: Electricity peaks reach about 8 GW, double the capacity in winter; while the water demand is about 20% higher.

It should be noted, in recent years, electricity demand in Qatar has grown three times faster than the world average due to the country’s strong economic growth and infrastructure projects. giant. The high level of electricity consumption is also due to the government price subsidy that makes electricity prices almost “free” in Qatar, suitable for all purposes.

The demand for fresh water in Qatar is growing at a rate of 12% per year, mainly due to industrial development, population growth as well as increased irrigation in the agricultural sector and anti-desertification. Since then, the desalination process has been significantly accelerated, contributing to increased power consumption.

Qatar in the Global Energy Transition Race (Next and Out)

Increase the share of renewable energy

Qatar is implementing a series of measures to reduce greenhouse gas emissions and assert its position as a leader in the development of new technologies.

Domestically, Qatar aims to increase the share of renewable energy in electricity consumption to 20% from 2024. At the same time, the transformation of energy in Qatar is also the realization of the development of public transport systems. new projects, including electric taxis and compressed natural gas (CNG) buses.

Qatar has established official bodies to deal with climate change (for example the National Committee on Climate Change – the national body responsible for climate policy formulation). Moreover, Qatar has participated in the GHG reduction program of the World Bank (WB) and the Global Association for Reducing Gas Emissions (GGFR). More specifically, Qatar Petroleum National Petroleum Company sets a “zero gas emission” goal by 2030. This goal will help develop new insights for other gas producing regions. Qatar Petroleum is promoting carbon capture and storage projects as it sees customers increasingly opting for low-carbon resources.

Qatar will need to make efforts to invest in low-carbon energy technology, by developing goals for energy efficiency and carbon concentration. Thereby, the challenge of Qatar is the reconciliation of new goals in the fight against climate change with the development of the domestic energy sector, along with new and “cleaner” sectors.

In recent years, electricity demand in Qatar has grown three times faster than the world average due to the country’s strong economic growth and huge infrastructure projects. The high electricity consumption is also due to the government price subsidy that makes electricity prices almost “free” in Qatar.
