Photovoltaic Industry Fill The International Energy Gap?

In the past year, the prices of natural gas, coal and other energy sources have continued to soar, and the global energy crisis has intensified. From Asia to Europe, the impact of energy shortages and rising prices has brought many problems to people’s lives.

More than half of India's coal-fired power plants have less than 3 days of inventory

Officials from the Indian Energy Department recently stated that 72 of the 135 backbone power plants in the region have less than three days of thermal coal stock, and the tight supply of thermal coal is very serious. The rainy season in India has caused many coal mines to suspend production, and the poor inter-state coal transportation has also led to a continuous decrease in coal inventories. At the same time, international coal prices have risen exponentially, causing Indian coal-fired power plants to worry about coal.

British officials "black lights" on the spot when discussing energy issues

Recently, Jonathan Briarley, an official of the British energy market regulator, attended an energy hearing through video. Just when he assured the MPs that the natural gas crisis would not cause power outages in the UK in winter, the room he was in suddenly darkened. Briarley had to interrupt the meeting to check, and other participants joked: "We really ran out of power!"

The prices of natural gas, oil and coal have soared in many parts of the world

Data shows that in the past year, the price of LNG in Asia has risen nearly 6 times; the price of natural gas in Europe has soared more than 10 times compared with last May. Oil prices also soared rapidly, with Brent crude oil breaking through US$83, the highest level in three years. While the prices of natural gas, coal, and oil have soared, an energy crisis is sweeping the world.

Germany will completely abandon its nuclear weapons in 2022, and the ten-year dispute ends

A series of energy crises has put many countries in trouble. But even so, Germany still insists on shutting down the last three nuclear power plants next year. Why did Germany give up nuclear power, which it had previously relied on, at a critical moment of energy shortage? What new alternatives did they find?

In southern Germany, the cooling tower of an abandoned nuclear power plant was demolished by blasting. Before the blast, a German line was projected on the cooling tower: "Make way for alternative energy sources." Ten years ago, nuclear power accounted for a quarter of Germany's electricity supply. Next year, Germany will shut down the last three nuclear power plants, becoming the first country in the Western industrial powers to completely abandon nuclear weapons.

The "complete abandonment" of nuclear power also cost Germany some costs, not only causing economic losses of 1.7 trillion euros, but also facing lawsuits from energy companies. In March of this year, the German government announced that it would provide financial compensation to companies that withdrew from the nuclear power industry, with a total amount of 2.4 billion euros, equivalent to approximately 18.6 billion yuan.

The data shows that from 2000 to 2019, the total electricity consumption in Germany was almost flat, and it has shown a downward trend in the past ten years. Among them, in 2019, Germany's national electricity consumption was 524 TWh, the lowest value since 2009.

Not only nuclear power, according to Germany's plan, all coal power plants will be shut down by 2038, and the use of natural gas will be abandoned by 2050. With the withdrawal of traditional energy sources, various new energy sources are accelerating their entry into the market. Data show that in 2020, renewable energy

Source power generation accounts for nearly 50% of the German power market, nearly three times that of ten years ago. Among them, wind power generation made the largest contribution, accounting for 27.4%; photovoltaic power generation accounted for 9.7%; the remaining 12.2% was contributed by biomass energy, hydropower and other Renewable energy composition.

German policies have also greatly affected other European countries. Also planning to abandon or reduce nuclear energy are Switzerland, Belgium, Spain and France. As a global nuclear power country, France plans to reduce the proportion of nuclear power from the current 75% to 50% by 2035.

South African mining company invests US$2.7 billion in autonomous power generation

On the one hand, we should eliminate old energy sources, and on the other hand, we should develop new energy sources. In fact, not only Germany, but also based on its own national conditions and resource differences, all countries are adjusting their energy structure according to local conditions and actively seeking new paths for energy transition.

Electricity is a key component of the mining industry and one of the largest operating costs. Recently, due to the continuous reduction of burden and power outages by the South African National Electricity Company, some local mining companies plan to invest US$2.7 billion to build photovoltaic and hydrogen power plants on their own to get rid of the shackles of the national grid. Northam Platinum, which owns the deepest platinum mine in South Africa, decided to generate electricity on its own before the government increased its maximum power generation capacity.

British construction of large-scale offshore wind farms, wind power once exceeded 50%

Not only in South Africa, in order to use diversified new energy sources, European countries are also looking for their own development paths based on different resource endowments. The United Kingdom has built large-scale offshore wind farms by virtue of its excellent resource conditions such as long coastlines, high wind speeds, and shallow seabed depths. At the end of last year, the UK's wind power accounted for more than 50% of the energy mix, a record high.

Countries take advantage of their local advantages to develop renewable energy

France, on the other hand, uses abundant offshore wind, water and forest resources to develop wind power and solar energy. It is estimated that by the end of 2028, the installed capacity of renewable energy power generation in France will quadruple from 2019. The United States relies on its vast territory to build large-scale solar power plants. Data show that by 2023, the US solar installed capacity will reach 324 gigawatts, more than three times that of 2020, equivalent to 40% of the current household electricity in the United States. Nordic countries such as Norway, Sweden, and Iceland have taken the lead in realizing energy replacement led by renewable energy by using abundant biomass, hydropower and geothermal resources.

Desert mirror sea! "Super Mirror" power station built in western China

In Dunhuang, Gansu, my country, more than 10,000 "heliostats" are lying quietly on the Gobi. They are arranged in an array of concentric circles, surrounding a heat-absorbing tower several hundred meters high, like a silver "sunflower". . These mirrors can follow the sun and convert sunlight into electricity through technological means such as concentrating and absorbing heat, storing and exchanging heat, and send 100% clean energy to thousands of households. The annual power generation capacity of this “super mirror power station” is about 390 million kWh. It can reduce carbon dioxide emissions by 350,000 tons per year, which is equivalent to the environmental benefits of 10,000 mu of forest.

China develops new energy according to local conditions

In our country, different geomorphic features are supporting different power generation methods. In Fujian Province, which is dominated by hills, photovoltaics cover a terrace along the mountains. In Zhejiang, where the water system is well-developed, fish ponds with an area of more than 4,000 acres can be fished underwater and photovoltaic power generation can be used on the water. On the North China Plain, wind from the north is pushing turbines to produce electricity.
