Some appliances can consume energy and increase the cost of electricity by turning off the power only by plugging it in!

According to Bargh News, it is not surprising that they use electricity when the electrical devices are on. However, all of these appliances still use electricity until we turn them off. In fact, more than 10 percent of our electricity bills are for devices we may not have used many times, but were on. As a result, a large amount of money from the electricity bill each month indicates the amount of energy lost.

So why do electronic devices consume energy even when turned off? When a device is plugged in, it consumes at least a small amount of energy. For many devices, this is a low amount of energy; It will be remarkable. In this section, we are going to introduce the most common household appliances that consume electricity even in the event of a blackout, as well as ways to reduce their environmental footprint.

Electronics that consume power outages:

1- Digital TV receiver Despite the ability to record digital image (PVR) on some TVs and of course all digital TV receivers, you can easily and automatically record your favorite movies and pictures and watch them at any time, but This is not possible without electricity. In addition, it requires energy to prepare for receiving remote signals.

2. The router and modem The modem will remain connected to the Internet, and the router will continuously play the Wi-Fi signal, even when no device is connected to it.

3- TV Have you ever paid attention to the red light of the TV even when it is off? This is just a sign that he is still using energy. Many newer TVs have a feature that can be turned on automatically by other devices or your voice, which also requires power to turn on through the controller.

4. Blu-ray / DVD player These devices usually display time and therefore always use energy to keep their LED displays on. In addition, they must be turned on to receive the signal remotely.

5. The computer When we turn off the computer, many of us do not actually turn it off, but put it in standby or hibernation mode. At this time, the computer is kept in low power mode so that programs remain active and turn on quickly when working with it. This is also true when the on / off button is not pressed, as it is on standby to receive the signal from you.

The CEO of Tavanir Company announced the implementation of the national “Electricity of Hope” scan from the beginning of November this year and said: “The purpose of this project in the country is to improve the pattern of electricity consumption in the home sector and high-consumption consumers are advised to increase their energy surplus by installing power plants.” Solar supply.

The CEO of Tavanir recommended high-consumption solar cells to be installed

The CEO of Tavanir Company announced the implementation of the national “Electricity of Hope” scan from the beginning of November this year and said: “The purpose of this project in the country is to improve the pattern of electricity consumption in the home sector and high-consumption consumers are advised to install their surplus energy by installing cells.” Solar supply.

Motavilizadeh added: “In this plan, electricity subscribers are divided into three groups: low consumption, good consumption and high consumption, and the criterion for determining the group among subscribers is to observe the monthly consumption pattern in hot and cold seasons of the year, which means that if subscribers are less than the pattern They are assigned to the low consumption group and a 100% discount is applied on their electricity bills.

According to Bargh News, Hosseini, CEO of Iran Energy Exchange, said at a meeting of the Conference on Financial Development in the Oil Industry, referring to the Energy Exchange’s capacity to finance the country’s oil industry projects: Reduce the volume of investment over time and leave it to the capital markets. He added: “We must recognize this shift in the financing paradigm from government financing to capital market financing, because government funding is currently limited and does not meet all the needs of the industry.”

He added: “In the future, the position of the capital market in the affairs of the country should be recognized.” The capital market is a complete ecosystem and can meet many of the country’s needs. Hosseini also continued: “The capital market with financing methods and structured tools in the world tries to direct financial resources to industrial projects, and we must note that the functioning of the capital market is different from the banking system.”

Electricity consumption will double in the next 10 years

“We need a lot of investment in electricity, oil and gas, and even global statistics show that in the future, investment in these sectors will be growing,” said the head of the Exchange and Energy Organization. He added: “According to statistics, in the next ten years, our electricity consumption will double and we need 50,000 megawatts of additional capacity.” There are also 26 petrochemical projects under construction that require $ 15 billion in financing.

* Why is financing through the capital market important? Hosseini said: “In the development of the oil industry, ie oil exploration and production over the next ten years, $ 600 billion of capital is needed, this is if the energy intensity is reduced by 50% and if this reduction is not done, this figure will increase even more.” As a result, attention to capital market capacity is becoming more important than ever. He continued: “In general, there are many reasons why we should move towards using the capacities of the capital market.” One of the reasons is the sharp fluctuations in oil prices and the government’s inability to finance the oil industry through the sale of oil.

The head of the Exchange and Energy Organization noted: “Also, oil and energy companies currently owe a lot to their contractors and can not even cover their current expenses, let alone be able to provide this amount of investment.”

Hosseini added: “Another reason for the need to use the capital market and get rid of government funding is the system of subsidies governing the energy sector, which makes the Ministry of Oil and Energy unable to obtain the necessary financial resources.”

* Reasons for neglecting financing through the capital market

He pointed out: “Due to the high capacity of the capital market, unfortunately, this market is not considered for some reasons, one of which is the bank-based financing system, which is the culture of the country’s financing system.”

The head of the Exchange and Energy Organization continued: “Also, the restriction of financing through the capital market to public joint stock companies is another reason that has made the share of the capital market in financing low.”

He also said: “Also, the capital market has little flexibility in receiving collateral compared to banks and only accepts collaterals that have high liquidity, which has made it more difficult to attract capital in this market than banks.” . One of the advantages of the capital market for financing is the transparency of this market, which unfortunately, due to some misconceptions, investors are afraid to enter this market.

In the end, Hosseini pointed out: “We in the Energy Exchange Organization do our best to increase our share of the country’s monetary market day by day by facilitating conditions and creating a competitive advantage over banks, and thus play an important role in financing oil industry projects.” Let’s play.
