What is wasted electricity?
Heating, showering and lighting were the uses that most decreased their consumption. While there was an increase in the use of electrical equipment such as television, computers, video games, clothes dryers and kettles.
Other expenses correspond to food refrigeration (refrigerator and freezer) and food cooking (stove, oven, electric stove) both with 5%; lighting and television occupy 4%. Expenditure on laundry (washing, drying and ironing) corresponds to 3%; while various uses (other equipment, computer, microwave, swimming pool, irrigation pump, coffee maker and video game console) and Stand By, consume 2% and the use of electric kettle and vacuum cleaner reach 1%.
However, “these consumptions do not ensure adequate levels of temperature, humidity, lighting and air quality inside their homes, and even in some cases, they do not have the necessary access to hot water, so that to reach adequate levels they should spend 50% more than what they spend today. This is why all the measures adopted will have a direct impact on family expenses and will improve their quality of life”.

Before I begin this discussion I would like to correct my purposely made typo in the headline. The original phrase was postulated by Antoine Lavoisier, known as the father of modern chemistry, in his famous law of conservation of matter which is stated as “energy is neither created nor destroyed, it is only transformed”.
In most wireless transmission scenarios it is necessary that the communication link is always available, no matter if there is any information transfer on it. Therefore, a large amount of electromagnetic and RF energy is released into the surrounding environment without being used. This problem is observed in wireless systems such as cellular telephone networks, WiFi and Bluetooth, and in general any communications medium that has access to the computing cloud.
One way to reuse the unused energy from the communication link is to use a system that collects or absorbs the RF energy available in the environment and converts it to direct current (DC) energy, this system is called RF Rectifier, Figure 2. Currently, energy conversion efficiencies well above 50% have been reported for these systems. This efficiency is due to the great progress and miniaturization in the manufacturing processes of integrated circuits.
Energy misuse examples
Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy policy[4] and are high priorities in the sustainable energy hierarchy. In many countries, energy efficiency is also considered to have a national security benefit because it can be used to reduce the level of energy imports from foreign countries and can reduce the rate at which domestic energy resources are depleted.
Other studies have emphasized this. A report published in 2006 by the McKinsey Global Institute stated that “there are sufficient economically viable opportunities for improving energy productivity that could keep global energy demand growth to less than 1 percent per year,” less than half the average of 2.2 percent. Expected growth through 2020 under a business-as-usual scenario. [10] Energy productivity, which measures the output and quality of goods and services per unit of energy input, can come from reducing the amount of energy required to produce something or from increasing the quantity or quality of goods and services from the same amount of energy … .
Energy waste
We may not be aware of the amount of energy used on the planet, but it is clear that the world without it is guaranteed to disappear. There are many studies worldwide regarding the use of energy by human beings and the International Energy Agency indicates that for 2013, the total energy consumption was 9,301 Mtoe, which is 3.89 x 10^20 joules (about 12.3 TeraWatts), a gigantic figure.
And if we talk about this, it is because every day we hear about new phones that come out on the market, and we take for granted that they have batteries that need to be charged almost every day. This seems obvious to us, and along the way we also forget that the electricity we consume comes from somewhere.
It is clear to everyone that consumption grows as populations grow and that this consumption is often not a consumption that increases linearly. Therefore, it is necessary to look for new sources of energy, to be much more efficient, and so on. Otherwise, eventually the human race will not only not be able to grow any more, but will collapse.
