Normally Kenya is selling a double price for a unit of electricity compared to Tanzanias without "cheap geothermal"

You know we still have thermal (diesel) power plants right? Which is factored in the billing inform of a fuel levy and their contracts have not run out.
Also I hope you know unlike Tanzania, Kenya is not in the habit of cancelling existing contracts arbitrarily without notice or compensation to the power producer because we respect and keep to contractual obligations.

I hope you also know that electricity cost in Tanzania is not less than Kenya! Tanesco was allowed to increase power cost per unit by 18% bringing that to a total of 269.02 Tshs/Kwh which is about Kshs 12.31212814645309 per unit for everybody irrespective of consumption.
I also hope you know that billing in kenya varies ie. If your domestic consumption is less than 100 kwh/month you pay kshs 10 per kwh above that you pay kshs 15 per Kwh, while commercial and industrial costs vary from Kshs 10.50 to 12 per kwh for small industrial and heavy industrial with no limit, while street lighting is kshs 7.50 per Kwh.

I also hope you know that demand for power in Kenya is increasing at between 3.8% and ~5% annually, and the thermal generation contracts are not being renewed ie Kenya is going geothermal which currently costs about kshs 7 per kwh.
I also hope you know that within the special economic zone in Naivasha companies will pay a cost of kshs 5 per kwh.

Now who does not understand physics! Dude you are a fool clearly i can see that

: The power available from the wind is a function of the cube of the wind speed. Therefore if the wind blows at twice the speed, its energy content will increase ten-fold (Hence the 1164%). Please go back to your aerodynamics books. Turbines at a site where the wind speed averages 8 m/s produce around 75-100% more electricity than those where the average wind speed is 6 m/s.

You're mixing up things too much....earlier I mentioned about transformity. The ability of one form of energy to transform into other forms efficiently.

Wind turbines use the power of wind to rotate the blades mechanically, converting that energy into electricity. Getting the reciprocal percentage ratio of the input energy and output (converted electrical energy) will not result into 1164% efficiency, no machine on earth can be that perfect.

No you are the one who does not understand, as the equation clearly shows for every 2 factor increment in wind speed wind power increases 8-10 ten fold (by a factor of 8 or 10). Now the appropriate question should have been how much of this wind power energy is actually converted to electricity (Hint: The problem is not drag or heat dissipation)

The answer is in the turbines which for obvious reasons are capped at between 1MW to 5MW. If we are able to go about the Betz law then we can harness all wind power generated. Find below a simple step by step calculation of what you fail to understand.

a) The world's largest wind turbine generator has a rotor blade diameter of 126 metres and so the rotors sweep an area of PI x (diameter/2)2 = 12470 m2 .

b) Given this is an offshore wind turbine, we know it is situated at sea-level and so we know the air density is 1.23 kg/m3 .

c) The turbine is rated at 5 MW in 30mph (14m/s) winds, and so putting in the known values will give, Wind Power = 0.5 x 12,470 x 1.23 x (14 x 14 x 14), which gives us a wind power of around 21,000,000 Watts.(Hence 1164%)

Q: Why is the power of the wind (21MW) so much larger than the rated power of the turbine generator (5MW)?

A: Because of the Betz Limit, and inefficiencies in the system. The Betz law means that wind turbines can never be better than 59.3% efficient.

Now i hope you see all your rants about drag and heat dissipation are not factored in this!

What is the rationale of having the Largest wind farm in Africa when your installed capacity is 2000MW?
Doest it make Kenya better than SA with 50K MW installed?

-Geothermal power plants is 21%.

-Thermal power plants ie Coal, Gas, Diesel etc 20%-48%, with coal having the highest at 30%-48% depending on the type of power plant eg Kenya's planned ultra super critical coal power plant (Amu power in lamu) will have the efficiency of 48%. Producing about 1000 MW upgradable to 4000 MW as energy demand increases.

-Wind, the most efficient fuel for electricity, creates 1164% of its original energy inputs when converted into electricity. Kenya has the largest wind farm in africa.

Advantages:
a) Geothermal energy is renewable; it is not a fossil fuel that will be eventually used up. The Earth is continuously radiating heat out from its core, and will continue to do so for billions of years .it will run out when the Earth does. In about 5 billion years.

b) The space it takes to build a geothermal facility is much more compact than other power plants. To produce a GWh (a gigawatt hour, or one million kilowatts of energy for one hour, an enormous amount of energy), a geothermal plant uses the equivalent of about 1,046 square kilometers (404 square miles) of land. Hydropower, wind, solar power plants use more land.

c) It is clean energy ie. No emissions only water vapour

d) It is a more reliable base load than Hydropower, wind and solar it does not depend on wind speed, the sun or rains to replenish rivers.

Disadvantage:

a) The initial cost is expensive compared to hydropower, wind, solar and thermal.Most developing countries do not have the resources or sophisticated infrastructure to build these power plants.

b) High technical expertise is lacking in most developing countries, especially geological expertise to be able to identify potential wells and to analyse rocks. That is why Kenya had to send geologists to Japan in the 1980's to learn.

c) Very strict geological conditions must be present to harness geothermal power.power the way kenya does. You must have the correct type of rocks that are permeable and high heat wells. That is a combination very unique to Kenya in east africa.

Now you are trying to digress! But if I am to play that game, what is the rationale of building(Currently stalled) one of the largest hydropower projects in Africa when your peak demand is 1200 MW and installed capacity is 1500MW? Does it make Tanzania better than SA with 50K MW installed?

Also a point of correction , Kenya has an installed capacity of 2,651 MW and 2000 MW peak demand. And yes we need wind because Kenya plans to be 100% green energy driven by december 2021 ie. We will decommission the diesel power producers when their contracts expire and we need other cleaner sources of power to take their place.

By the way other power producers are also coming in to generate solar power .We already have the largest solar farm in east and central africa in Garissa 55 MW, 40 MW Rumuruti, 40 MW Radiant, 40 MW Eldosol (Under construction), 40 MW Alten(Under construction), 10 MW Kenyatta University, 52 MW Malindi and 50 MW Kopere (Under construction).

We also have other hydropower projects coming up in the future

- High grand falls power project (693 MW)
- Mutonga power project (60MW)

Once the court cases by activists are over, we will also have the largest and only ultra supercritical coal power plant (1050 MW) in east and central africa.

Installed capacity ni around 2,800 MW. Kama hujui kitu uliza uambiwe badala ya kujifanya mjuaji kumbe hujui lolote. Unaaibisha Tanzania bure tu.

Make it 3000MW, it is not and will never be close to 50K mpaka unakufa, infact the Kenyas installed capacity is not enough to power a Plant in Witwatersrand ,
My point is, nini maana ya kujiona Bora sana ikiwa wapo walio Bora na hawajivuni?

And we still have 10,000 MW of untapped geothermal power in the rift valley. We will overtake other countries soon with new IPPs coming up.

For Sure. Alafu Sasa ikiwezekana nuclear plant Moja ijengwe Lodwar. Kenya can power the whole EAC with clean energy.

Electricity in Kenya is More efficient than any East African Country. The Peak demand is also well managed & stable.
Tanzania has a Population of about 60 Million and generates 1500MW which is even Lower than Kenya's peak demand & Most of this energy is generated using gas; hydropower is also a significant source of power. Tanzania has a Capacity of 1,521 MW with only 60% of this Power available, most of the time, as it highly depends on hydroelectric plants

That has been my argument all along. How much of that energy is converted into electricity and by measuring the input and output power you find that it is less than 60% efficiency. Drag and heat dissipation due to mechanical friction is the reason you don't convert all that wind power into electricity.

It is impossible to harness all the wind power in practice because there will always be some energy loss doing mechanical work (rotating turbines). All these measurements you come up with are mainly for qualitative purposes, to get the idea of how much wind speed will output. It doesn't address quantitatively the efficiency of energy converted.

I have been beating this dead horse for a while, I'm glad it is (finally) rising up. You are admitting that turbines can never produce more that 59.5% efficiency.

Lodwar hakuna maji ya kutosha nuclear power plant inafaa ijengwe kwa ziwa au ocean for the purpose of cooling the plant,hawawezi risky lake turkana because it's the only source of water in that area.

Speaking of nuclear power, France is the country that generates most of its electricity from nuclear power. More than half of their electricity comes from nuclear power. The sad thing is that they get their Uranium ores from Niger but they pay almost nothing for these raw materials. As a result, Niger remains one of the poorest countries in the world while France even has a nuclear aircraft carrier.
France has guaranteed the dictator in Niger military protection so that he can stay in power forever. Most of these Francophone countries have dictators who have stayed in power for more than 20 years with France giving them security and robbing their mineral resources. Let us thank God we were not colonized by these mofos called France. When the British left Africa they went and never came back. The French on the other hand never left
