1. Global energy demand is gradually increasing
In 2020, the demand for natural gas will decline by 1.9%. This is partly due to the change in energy use during the period of the most serious damage caused by the new epidemic. But at the same time, this is also the result of a warm winter in the northern hemisphere last year.
In its Global Gas Security Review, the International Energy Agency (IEA) said that natural gas demand may rebound 3.6% in 2021. If unchecked, by 2024, global natural gas consumption may increase by 7% from the level before the new epidemic.
Although the transition from coal to natural gas is still in progress, the growth of natural gas demand is expected to slow down. The International Energy Agency said that governments may need to legislate to ensure that the growth of natural gas related emissions will not become a problem – we need more ambitious policies to transition to the goal of “net zero emissions”.
In 2011, natural gas prices in Europe have risen by 600%. From 2022 to now, a series of chain reactions triggered by the conflict between Russia and Ukraine have also directly led to a greater shortage of global energy, and the supply of oil, natural gas and electricity has been greatly affected.
In the Northern Hemisphere, the beginning of 2021 is interrupted by a series of extremely cold extreme weather events. Large areas of the United States are affected by the polar vortex, which brings ice, snow and low temperatures to the southern state of Texas.Another extremely cold winter in the northern hemisphere will put additional pressure on the already stretched natural gas supply system.
To cope with the growing energy demand in cold weather, it is not only necessary to solve the challenges brought by low natural gas inventory. Hiring ships to transport LNG globally will also be affected by insufficient shipping capacity, which makes it difficult and expensive to cope with the surge in energy demand. The International Energy Agency said, “In the past three northern hemisphere winters, the daily spot LNG ship rental fee has soared to more than 100000 dollars. In the unexpected cold current in Northeast Asia in January 2021, in the case of the actual shortage of available shipping capacity, the ship rental fee has reached a historical high of far more than 200000 dollars.”
Then, in the winter of 2022, how can we avoid the impact on our daily life due to the shortage of resources? This is a question worth thinking about
2. Energy related to our daily life
Energy refers to the resources that can provide energy. The energy here usually refers to thermal energy, electric energy, light energy, mechanical energy, chemical energy, etc. Materials that can provide kinetic energy, mechanical energy and energy for human beings
Energy can be divided into three categories according to sources: (1) Energy from the sun. It includes energy directly from the sun (such as solar thermal radiation energy) and energy indirectly from the sun (such as coal, oil, natural gas, oil shale and other combustible minerals as well as biomass energy such as fuel wood, water energy and wind energy). (2) Energy from the earth itself. One is geothermal energy contained in the earth, such as underground hot water, underground steam and dry hot rock mass; The other is atomic nuclear energy contained in nuclear fuels such as uranium and thorium in the earth’s crust. (3) Energy generated by the gravitational attraction of celestial bodies such as the moon and sun on the earth, such as tidal energy.
At present, oil, natural gas and other energy resources are in short supply. Can we consider the energy we will use? The answer is yes. As the core of the solar system, the sun is delivering huge amounts of energy to the earth every day. With the development of our science and technology, the utilization rate of solar energy is gradually improving, and it has developed into a technology that can obtain energy at low cost. The principle of this technology is to use solar panels to receive solar thermal radiation energy and convert it into electric power storage. At present, the low-cost solution available for families is battery panel+household energy storage battery/outdoor energy storage battery.
I would like to give an example here to help you better understand this product.
Someone asked me, how much electricity can 100 watt solar power generate in a day?
100 W * 4 h=400 W h=0.4 kW h (kWh)
One 12V100Ah battery=12V * 100AH=1200Wh
Therefore, if you want to fully charge a 12V100AH battery, you need to continuously charge it with 300W solar energy for 4 hours.
Generally, the battery is 12V 100Ah, so the battery that is fully charged and can be used normally can output 12V x 100Ah x 80%=960Wh
When using 300W appliances, theoretically 960Wh/300W=3.2h, it can be used for 3.2 hours. Similarly, a 24V 100Ah battery can be used for 6.4 hours.
in other words. The 100ah battery only needs to use the solar panel to charge for 4 hours to power your small heater for 3.2 hours.
The most important thing is that this is the lowest configuration on the market. What if we replace it with a larger battery panel and a larger energy storage battery? When we replace them with larger energy storage batteries and solar panels, we believe they can supply our daily household needs.
For example, our energy storage battery FP-F2000 is designed for outdoor travel, so it is more portable and light. The battery has a capacity of 2200Wh. If a 300w appliance is used, it can be used continuously for 7.3 hours.
