In the context of the currently developing energy crisis and the prospectively developing climate crisis, the following questions arise:
What should be the structure of a diversified energy sector that would have a high level of energy security and be fully resilient to the energy crisis?
What should be the share of different energy sources, including renewables and carbon-free energy sources, within a diversified energy sector that would be fully resilient to the energy crisis?
What should be an energy sector that is resilient to energy crises on the one hand and takes into account the needs of citizens, the needs related to the issue of sustainability, the reduction of greenhouse gas emissions, i.e. it should also be a pro-climate and pro-environmental energy sector?

What eco-innovations and green energy technologies can be developed and implemented to help build backyard power plants and mini-generation plants that can be built quickly within the framework of renewable energy sources and thus more smoothly survive the developing energy crisis?
With much of the energy industry operating on the basis of burning fossil fuels, accelerating the development of renewable energy sources may help the economy to get through the currently developing energy crisis. Unfortunately, it will take time to build large-scale power plants such as nuclear power plants or hydrogen production companies for the development of hydrogen energy. In contrast, the energy crisis is already developing. In addition, in order to increase the diversification of energy sources and realise an environmentally and climate-friendly transformation of the energy sector, it is necessary to develop various renewable and emission-free energy sources. In this way, the independence of the national energy system can be increased and the level of energy security enhanced. Countries where the development of renewable and zero-carbon energy sources was neglected in previous years are now facing more economic problems due to the developing energy crisis. An example of this type of country is the one in which I operate, i.e. a country in which three quarters of energy is still produced on the basis of dirty, combustion-based energy, i.e. based on the combustion of fossil fuels, wood and other materials or organic waste. In view of the current energy crisis and the prospective climate crisis, the following question therefore arises: What kind of backyard power plants, mini-generation plants can be built quickly to become operational even before the next heating season? What eco-innovations and green energy technologies can help to build backyard power plants and mini-generation plants that can be built quickly within the framework of renewable energy sources and thus more smoothly survive the developing energy crisis?

This topic is interesting.
The benefits of renewable energy use are less global warming, improved public health, inexhaustible energy, jobs and other economic benefits, stable energy prices, reliability, and resilience.
But I believe that renewable energy is not a viable alternative to fossil fuels. If not good enough to be a replacement source, then regardless of its other desirable attributes, renewable energy is not truly viable.

Which type of renewable and zero-carbon energy sources will develop most rapidly in the future in connection with the currently developing energy crisis and the long-term, multi-year global climate crisis?
In the shorter term (a few quarters), the energy crisis is developing, fossil fuel prices are rising, and the price of energy produced from burning fossil fuels is rising. In the longer term (many years), a global climate crisis will continue to develop as a result of the continuing process of global warming resulting from the still high levels of civilisational CO2 emissions into the atmosphere.
In view of the above, I address the following question to the esteemed community of researchers and scientists:
What kind of renewable and zero-carbon energy sources will develop most dynamically in the future in view of the currently developing energy crisis and the developing global climate crisis in a multi-year perspective?

Relevant answer
Answer
You need of course a windmill with an electricity generator, a lithium battery and the required electronics to adapt the windmill to the battery ant the battery to the heater. For the heater, I would recommend to use a heat pump which, for a given amount of heat, uses less electricity than a resistor, since it "pumps" a part of the heat in a low temperature heat source (ar, lake, river, gound, waste heat). The performance of the heat pump strongly depends on the heating temperature and the temperature if its heat source. Therefore, the heating system should be conceived to use the lowest possible temperature (e.g. floor heating) and the heat source should be at the highest possible temperature.

We know wind turbines extract energy from the wind in order to produce electricity, the wind downstream of a turbine has a lower energy content than the wind upstream. Suppose, the understudy region is formed of two zones (Figure attached). In the dark red zone, the initial wind velocity is greater than that in the light red zone.
Bearing in mind the different initial wind velocities, How to determine the resulting wind speed, due to the wake effect of turbine 1 on turbine 2 (case 1) and of turbine 3 on turbine 4 (case 2)?
Scenario: The problem in case 2, perhaps the recovered wind speed at turbine 4 is greater than V0 =8 m/s (initial speed at light red region)
Relevant answer
Answer
Dear Bassam:
At the first, and as you know that several different factors influence the potential wind resource in an area. The three main factors that influence power output are: wind speed, air density, and blade radius. Wind turbines need to be in areas with a lot of wind on a regular basis, which is more important than having occasional high winds.
# Wind speed:
Wind speed largely determines the amount of electricity generated by a turbine. Higher wind speeds generate more power because stronger winds allow the blades to rotate faster. Faster rotation translates to more mechanical power and more electrical power from the generator. The relationship between wind speed and power for a typical wind turbine is shown in Figure (a).
Turbines are designed to operate within a specific range of wind speeds. The limits of the range are known as the cut-in speed and cut-out speed. The cut-in speed is the point at which the wind turbine is able to generate power. Between the cut-in speed and the rated speed, where the maximum output is reached, the power output will increase cubically with wind speed. For example, if wind speed doubles, the power output will increase 8 times. This cubic relationship is what makes wind speed such an important factor for wind power. This cubic dependence does cut out at the rated wind speed. This leads to the relatively flat part of the curve in Figure (a), so the cubic dependence is during the speeds below 15 m/s (54 kph).
The cut-out speed is the point at which the turbine must be shut down to avoid damage to the equipment. The cut-in and cut-out speeds are related to the turbine design and size and are decided on prior to construction.
#Air Density:
Power output is related to the local air density, which is a function of altitude, pressure, and temperature. Dense air exerts more pressure on the rotors, which results in higher power output.
#Turbine Design:
Wind turbines are designed to maximize the rotor blade radius to maximize power output. Larger blades allow the turbine to capture more of the kinetic energy of the wind by moving more air through the rotors. However, larger blades require more space and higher wind speeds to operate. As a general rule, turbines are spaced out at four times the rotor diameter. This distance is necessary to avoid interference between turbines, which decreases the power output.
# There's a phenomenon, which referred to as the reduced wake effect:
During curtailment, less power is extracted from the wind and thus the wake effects are reduced. This leads to a wind speed increase at the downstream turbine and therefore to an apparent increase of its available power. This phenomenon is referred to as the reduced wake effect.
# So you could benefit from this valuable article about this topic:
"Analysis of the reduced wake effect for available wind power calculation during curtailment"
# Abstract:
With the increase of installed wind power capacity, the contribution of wind power curtailment to power balancing becomes more relevant. Determining the available power during curtailment at the wind farm level is not trivial, as curtailment changes the wake effects in a wind farm. Current best practice to estimate the available power is to sum the available power calculated by every wind turbine. However, during curtailment the changed local wind conditions at the wind turbines lead to inaccurate results at the wind farm level. This paper presents an algorithm to determine the available power of a wind farm during curtailment. Moreover, results of curtailment experiments are discussed that were performed on nearshore wind farm Westermeerwind to validate the algorithm. For the case where a single turbine is being curtailed, it is shown that the algorithm reduces the estimation error for the first downstream turbine significantly. Further development of the algorithm is required for accurate estimation of the second turbine. All further downstream turbines did not experience a change in wake conditions.
I hope it will be helpful ...

Wind energy has been established as the most profitable and tested energy since ancient times. It was first used on sailboats since ancient times, followed by windmills. Today it is included in "clean" energy sources, as they are commonly called non-polluting energy sources. A large part of the cost for the construction of a wind turbine is its support on the ground. Large wind turbines need huge reinforced concrete bases that use the same weight to prevent the wind turbine from overturning, which receives very large gusts of wind. There are wind turbines where their base consists of 2000 cubic meters of reinforced concrete. That is, they weigh 2000 m3 X specific weight of reinforced concrete which is 2450 kg / m3 = 4.900000 kg or 4.900 tons The cost of reinforced concrete in the mountains exceeds 300 euros per m3 That is, the cost of the base is 2000 m3 X 300 euros = 600,000 euros. If you put in the excavations, it is very expensive. In order to reduce the cost of support but also the cost of electricity, as well as the pollution from the manufacture and transport of concrete, the concrete base must be removed and replaced with deep ground anchors like that of the patent which I hope is the strongest anchor worldwide. The cost of support with my patent of this particular wind turbine of 2000 m3 will not exceed 80,000 euros.

Energy security is the most important factor in the development of a country, especially one that has a shortage of traditional resources. In this case, renewable energy is one of the possible ways to solve the problem, where a significant role is assigned to wind generators. Compact offshore wind turbines are already occupying their niche in the market and their share will grow. This can be confirmed by the advantages that are described in the above and other materials. At the same time, you need to take into account, for example, the problems of this winter in Texas and the dull look of frozen wind turbines with subsequent energy problems. And that means need balance, balance, and compliance!

"Mathematical Modelling of Grid Connected Fixed-Pitch Variable-Speed Permanent Magnet Synchronous
Generators for Wind Turbines"
By 'Zaiming Fan'
With Equations and codes (MATLAB & C).
Abstract :
This project develops the mathematical model of a 10kW permanent magnet
synchronous generator (PMSG), which is designed for a fixed-pitch variable-speed
wind turbine, and its corresponding simulation model for the control of the PMSG for grid connection using MATLAB/Simulink. The model includes sub-modules, such as a model of the wind speed, a model of the PMSG, a model of the rectifier circuit, a model of the boost chopper circuit, a model of the space vector pulse width modulation (SVPWM) inverter, and a model of the power grid voltage sag detection for low voltage
ride through (LVRT). The rectifier is a 3-phase uncontrolled diode full-bridge circuit.
The boost chopper circuit offers a direct current (DC) power supply with constant
voltage for the inverter. Sampled signals of instantaneous 3-phase voltage (from the
power grid) to obtain the phase angle, frequency and amplitude, are used to generate SVPWM signals to control the inverter’s output. In the model of the power grid voltage sag detection, a novel direct-quadrature (DQ) transformation is introduced to detect the voltage sag of the power grid.
This thesis systematically analyses the mathematical model along with its sub-modules, and creates simulation models using MATLAB/Simulink. The simulation results demonstrate that both the mathematical model and simulation model are correct, and the parameters of the generator output are synchronised with the main grid.
I hope it will be helpful....

For example, according to the global wind report, 2019 "investment should be rising steeply and steadily, in line with the IPCC’s call for global investment in clean energy to be massively scaled up to USD 2.4 trillion annually up to 2035, from some USD 282 billion in 2019, to maintain a 1.5-degree pathway."
Relevant answer
Answer
Renewable power producers have been mostly sheltered from the impact of the pandemic. Declining electricity demand and lower prices due to the Covid‑19 crisis resulted in sharp revenue drops for major utilities all around the world, especially those deriving revenues from wholesale electricity markets.

In short, the benefits of using fuzzy controllers can be illustrated as follows:
They are quick to comprehend conceptually: the ideas underlying them are very basic and fundamental;
They are flexible: they enable emerging Fuzzy structures to be applied to their features by applying new information to established rules;
They are tolerant of incorrect data: calculation precision errors or randomness affect device efficiency little;
You might model nonlinear processes of subjective complexity: structures like "Adaptive Neuro-Fuzzy Inference Processes" will do that;
They can be founded on the experience and actions of the system;
They can be combined easily and deliver improved efficiency with conventional control systems;
They are built on the normal human language and allows new rules to be introduced, exceptions and new behaviours to established Fuzzy structures.

I am trying to obtain the electric energy that can be obtained from a specific wind turbine. I have two questions about wind energy:
1. I am using the following method to calculate the electric energy (in kWh/yr) from a wind turbine: I have a hourly data series of wind speeds in a study case. With this 8760 wind speeds, the first step was calculate the Weibull probability density function f(v), with two parameters (shape and scale). The second step was search the power curve of the wind turbine, obtaining a power value for each speed value. The third step was multiply f(v) with each power value, according a defined interval for speed (delta V). The last step was applied a sum for all the power values and multiply them by 8760. This is the correct way to obtain the electric energy generated from a wind turbine?
2. If a have a data series of wind speeds in a year (hourly), how can I calculate and, later, to plot the hourly electric energy obtained from the wind turbine? I think in this case I do not have to calculate the Weibull probability density function f(v), because I am going to plot the hourly electric energy value, so I am thinking to multiply the hourly speed value with the power value corresponding to that speed (obtained from the wind turbine power curve). Would it be the correct way to do it?
I appreciate so much your help!

ew There are no miracles. In fact, there are two initial sources of so called "renewable" energy - solar and gravitational (Earth's rotation energy, for example). The whole question is how much waste will be allocated in the specific process of its fixation. For example, harvesting of "solar energy" produces a significant amount of waste (production of the elements themselves, copper conductors, heat, etc.). For strange reason, if the waste is concentrated in another place (where the elements are produced, for example), the technology of "solar energy" is considered to be "nature-friendly". As to the substance of the matter, the use of “conditionally renewable energy” to produce a source of non-renewable energy does not seem to me a reasonable idea. In addition, it should always be taken into account that any energy conversion has limited efficiency ...

Relevant answer
Answer
The new study indicates that large natural climate cycles are a potential culprit.
Using models to study factors that influence global wind behavior, researchers have found that large climate patterns - which affect temperatures in certain parts of the world - have a major impact on wind speed. Temperature differences between adjacent areas, or between the ocean and adjacent land areas, can affect air flow.

Mankind's ideas of energy production must be re-thought in order to survive... The relyance on fossil fuels or nuclar energy does not help. All sources of energy should be thought about, so tidal energy is OK, but not very efficient. It has be shown to work (e.g. in the Netherlands and France in estuaries of rivers)... Wind energy is efficient in costal areas but has been depending on state funding... But do you honestly think that coal mining or the production of nuclear energy/Waste is not depending from state funding/subsidies?
An introduction can be seen by the Open University, see URL:
Do you have helpful ideas or thougths?
Relevant answer
Answer
All of these advances inevitably led to the assumption that new resources were not needed in the development process. This is due to the fact that based on fossil fuels - on the other hand.In reality, this contrast is far from straightforward and requires more thoughtful study. Carbon dioxide capture and storage (CCS) and methane management technologies at all stages of the increment in the cost of energy from fossil sources can help fulfill large-scale tasks to reduce CO2 emissions while fossil fuels are still part of the energy system. Thus, these measures allow fossil fuels to become part of the solution, rather than remain part of the problem. A rational economy plays an important role in the energy systems of each technology.

I think that renewable energies are well known ...
As for the use of wind to produce electric energy, in my view, yes. It is possible to use this energy. Still, the problem is that a comprehensive study of wind speed in the Middle East must be presented, before starting studies on this energy anywhere. I think in Iraq, we have a good rate of speed in northern Iraq, some mountains and hills surrounding Iraq and open places, but in central Iraq specifically, I think wind energy is weak and cannot be exploited.

Wind turbines have experienced very important technological innovations in last few decades and cost per installed kWe keeps being improved. New materials and more adequate tools used for exploring the suitability of sites are the drivers for the global expansion of this renewable source. Wind turbines don't need to be operating for more than 20-30 years to be profitable. It may be profitable to replace them at some point for larger, more technologically advanced models.
