The so-called “Flex Alert” was issued in July 2021 when the outside temperature rose to much higher levels in California than usual. “Flex Alerts” are, in effect, recommendations issued to warn interested people of the possibility of a power outage, that is, the lack of individual protection activities. This can be true for both the residential and commercial sectors as well.
In Fresno County, where I live, the designated time was from 4 pm to 9 pm when the “Flex Alert” was issued. Why is this time zone? Simple: This is the time of day when energy supply is usually looking at maximum daily demand.
In the world of electronics, there is what is known as heat transfer. The idea behind heat transfer is to transfer heat from one object (or medium) to another, as energy cannot be produced or destroyed, it is only altered.
For example, in a high voltage transmission cable, when electricity is flowing through such, the flow of electrons is essentially the basis of that flow of electricity. The associated voltage applied acts as a pressure to push out the electrons in the cable. Add to this flow resistor for electronic bunching (a condition that typically occurs along the outer edge of the cable and causes energy loss in the form of heat). The higher the resistance, the more heat builds up in the cable.
If the accumulated heat cannot be dissipated efficiently (for example, if it is transferred to another medium such as the surrounding air), it is more likely that the service will be interrupted due to overload.
Potential waste of energy
Therefore, appliances that are located throughout the home, such as washing machines, dryers, dishwashers, ovens / stoves, refrigerators, iron, televisions, hair dryers (so-called large energy users or consumers), and their power distribution. Impact on (grid) system.
With the exception of the refrigerator (the refrigerator operates 24 hours a day, 7 days a week), you can plan the usage time for each of the above. Ovens / stoves are usually most often used in the evening, that is, when cooking dinner, which is the time of highest energy demand.
Now, during peak summer temperatures, especially under overly hot conditions, this requires the above appliances to work harder, which can generate more waste. I have.
Also, depending on the number of these appliances in constant use, the more ovens / stoves used, the greater the demand for electricity (for electricity) or natural gas (for natural gas). Therefore, the cost is high. It is related to the use of the device, which increases the demand for energy supply at the power plant and causes more damage to the air. This is also known as the “upstream result.”
To get started, the efficiency of the appliance can make a big difference.
Next is the usage time. If time permits, it may be helpful to plan your cooking during the morning hours. These time zones are times when energy usage is low. If specified for dinner, it can be reheated in an oven, stove, microwave, etc. at the appropriate time after refrigeration. These actions can reduce energy consumption, allowing for more money and upstream air. Saved (in the generator source). The same applies to the use of the dishwasher in the early morning.
So, in summary, appliance usage time and appliance efficiency can make a big difference when it comes to energy savings. How about choosing an appliance? Yes, it can also offer benefits.
Taking a rice cooker as a typical example, press the on / off button of the rice cooker to turn it on, and when the rice is completely prepared (pre-soak, stir, rinse, boil / steam with the appropriate amount of water) Add), “It’s almost a” hands-off “operation since then.
Compare this to cooking rice in a pot above the stove. This method includes human intervention, surveillance, and burner control. It is important to note that inadvertent moments can cause the water in the pot to boil, requiring human intervention and monitoring in the form of burner or heating element control.
In the former and latter cases, the rice cooker cooking process and the stovetop cooking process may consume less energy. And the rice cooker is just one example.
Regarding the “Flex Alert” mentioned at the beginning, the power outage was avoided by supplying power to my house and neighbors who lived at the time when the warning was issued. Having encountered excessive and repressive high temperatures, it is good to know that energy conscious people have implemented conservation measures. Imagine energy, money, and, of course, air savings.
