Chapter 726 Development prospects brought about by technological breakthroughs (more explanations)
How big is the desert's solar power potential?

Take the Taklamakan Desert, the largest desert in China, as an example.

The total area of ​​the Taklamakan Desert is 33 square kilometers, surrounded by inaccessible areas.

According to NASA research, each square meter of desert receives about 2000 kWh to 3000 kWh of solar energy per year.

If all the solar energy can be converted into electrical energy, it will be enough to use 1 kilowatt electrical appliances for 3000 hours. Based on the average annual household electricity consumption of 6000 watts, only 2 square meters of desert can meet the electricity consumption of a family for a year.

According to this perfect conversion efficiency, the area of ​​33 square kilometers in the Taklamakan Desert can meet the electricity consumption of nearly 1600 billion households.

Of course, this conversion efficiency is too exaggerated.

If there is such a conversion efficiency, those princes in the Middle East would have eaten the dirt long ago.

At present, the conversion rate of solar panels is far from reaching the level of 100% conversion of solar energy.At present, there are mainly two types of solar power generation equipment for human beings, one is concentrated solar energy and the other is photovoltaic solar energy.The conversion of photovoltaic solar energy is more stable than that of concentrated solar energy, and can achieve a conversion efficiency of up to 23%.However, considering the high temperature in the desert, sand and dust, and the aging of battery panels, the actual conversion efficiency needs to be greatly reduced.

This is real-world solar power efficiency.

The solar power generation technology mastered by Wu Siyuan has a higher conversion efficiency, the theoretical value can reach 32%, and the attenuation rate is also very low, which means that its service life will be very long.

Even if it is impossible for solar panels to cover all the area of ​​the desert, 50% of the area will be used for maintenance.

Calculated according to the solar power generation efficiency in Wu Siyuan's hand,
According to such forecasts, the annual power generation of the Taklamakan Desert will be able to meet the needs of 480 billion households.

Of course, this is household electricity.

Household electricity consumption is only a part of a country's electricity consumption.

Compared with the electricity used by industrial giants, household electricity can only be said to be pediatrics.

For example, Taiwan Machinery & Electric Co., Ltd. in Wanwan Province, the electricity consumption of an enterprise has reached 160 billion to 170 billion kilowatts.

On average, 5000 million kilowatts of electricity will be used every day.

It accounts for [-]% of the overall power generation of Wanwan Province.

However, the electricity consumption of Big Curve House in three months is only 7000 kWh, and the average is only [-] kWh a month.

The two are not on the same level at all.

Industrial electricity consumption is the bulk, generally accounting for 60.00% to 70.00% of total social electricity consumption.

However, using Wu Siyuan's solar power generation technology, the annual power generation capacity of the Taklamakan Desert can easily be met, and there are still several times the surplus.

Even with real-world solar power generation technology, the annual power generation in the Taklimakan Desert can meet the country's electricity needs.

This is just a desert.

If half of the deserts in China are covered with solar panels, the electricity generated by it can meet the needs of the world.

And the deserts all over the world are even bigger!

The reason why desert photovoltaic power generation has not been applied on a large scale before is because electricity transportation is a big problem.

The desert itself doesn't consume that much power.

Electricity needs to be delivered to developed areas.

In this way, the longer the power transmission line, the more loss it will have, and the future maintenance of such a long-distance transmission line is also a huge problem.

I have mentioned the issue of cost before.

However, the magnetic field resonance wireless charging technology of heaven and man can realize long-distance power transmission at low cost.

Whether it is the construction of magnetic field resonance electric piles or the later maintenance, the cost is much lower than that of the grid.

Once promoted, the most intuitive impact is that electricity prices will continue to decline.

At present, the cost of domestic coal-fired power generation is about 3 to 5 cents. This is still a lot of coal in Huaguo, and the cost of coal combustion is relatively low.

The cost of generating electricity is 7 to [-] cents, and then sold to the grid for [-] to [-] cents, and finally falls to the user, which is more than [-] cents.

Industrial and commercial electricity will be more expensive.

However, after the magnetic field resonance electric piles are rolled out across the country, the electricity generated by the solar energy in the desert can be transmitted, and the cost of electricity prices can be reduced by more than 50.00%.

Over time, electricity tariff costs can be further reduced.

The reduction in the cost of domestic electricity prices will have an immediate stimulating effect on the economy, which can be said to be a great benefit.

Some power-consuming enterprises, such as the steel industry, electrolytic aluminum industry, electroplating industry, and chip production industry, will greatly reduce their costs, at least 5.00% to [-]%, and more than ten percent are possible.

These industries are low-profit industries, and they all rely on volume to make profits.

Such a high cost reduction can directly explode their profits.

Of course, this huge profit will not last long, and the invisible hand of the market will mediate by itself.

However, this reduced cost will be transmitted throughout the entire industrial chain, and the final result will be reduced product costs, increased profits, and enhanced competitiveness.

In addition, the decline in electricity prices will also cause many previously unprofitable products to become profitable now.

For example, Wu Siyuan has been thinking about vertical farming for a long time.

Vertical farming, or more specifically vertical farms, are cylindrical in shape with floors stacked like chips.

Each floor is a piece of farmland with a complex irrigation system.

All crops will be grown in a controlled environment, and electronic eyes will be used to check whether they are mature. They can be planted and harvested 365 days a year without interruption.

It has both advantages and disadvantages.

The advantage is that the products produced are organic agricultural products, and the health is guaranteed. In the process of planting indoor farms, pests can be effectively controlled, so that no pesticides are used, and the crops can grow organically.

Secondly, transportation costs can be greatly reduced, and urban residents can [pick up vegetables] on the spot, and the source can be traced.

In addition, it is also very convenient in management. Due to the centralized production, it can be more concentrated and efficient in the treatment of agricultural pollution. If the device is well done, it can also realize the sustainable use of resources.

The arable land used by traditional agriculture is likely to need to be returned to forests, while vertical farming does not have such a problem.Returning farmland to forests is an effort to combat global warming, through which deforested forest areas can be returned to their pristine state, repopulated with vegetation and sheltered by various animals, while reducing carbon dioxide in the atmosphere and providing And tourism offers beautiful scenery.

Of course, the disadvantages of vertical farming are also obvious.

First, the input cost is high, involving multiple links such as architectural design, engineering arrangement, agricultural operation, and agronomic planning.

Second, the quality of technical and management personnel is required to be high.

The third is that it consumes a lot of power. Compared with traditional greenhouse cultivation, vertical farms require greater power input, and the economic cost is very high.

Electricity costs for vertical farming are six to seven times that of conventional farms.
