How the world's largest solar power plant works

More and more countries of the world are beginning to use alternative energy sources, including solar. Therefore, modest rooftop panels are being replaced by “solar farms” spread over vast areas. So, the fourth-largest solar power plant in the world, Benban Solar Park is located in Egypt, covers an area of 37 square kilometers, and generates a capacity of 1,650 MW. In third place is Shakti Sthala, located in the city of Pavagada in India. Its area is 50 square kilometers and has a capacity of about 2000 MW. The second is the Chinese Hainan Solar Park. It consists of 672 photovoltaic arrays and produces 2,200 MW. What is the largest solar power plant in the world and how is it arranged? Watch in our video!

Energy 101: Wind Power

Our animated correspondent “Little Lee Patrick Sullivan” explains how the wind can be used to generate power, including where wind comes from, its history as a power source, how wind farms generate electricity and what’s likely to be the first major offshore wind project in the U.S.

Ask This Old House home technology expert Ross Trethewey sees a robotic, ground mounted solar array that mimics a sunflower.
SUBSCRIBE to This Old House:

1. The solar panel array is installed by securing four massive earth screws into the ground to act as a base.
2. The solar panel array is then craned off of a truck into place on top of the earth screws.
3. A trench is dug from the array to the house. Conduits are placed in the trench containing a hot, ground, neutral, and a Cat5 cable. The Cat5 cable allows the system to take in weather and location data.
4. Once the array is secured to the base and wired up, the latitude and longitude of the area is programmed into the system and it can be powered up.

The solar flower Ross saw installed is called the SmartFlower, and it is manufactured by SmartFlower Solar (

Hydroelectric Power Plant || Hydro Power Plant || Pumped Storage Power Plant

world’s largest hydroelectric power plant –

At thermal power station generate electricity from steam to convert water from water to steam high grade of coal burned at the thermal station. but in hydroelectric power stations, direct water is used to generate electricity.
the hydroelectric power plant is the best renewable power plant, the hydro plant is purely environmentally friendly.
in this video talking about how hydroelectric power plant works and also talking about pumped storage hydroelectric plant, their working efficiency and cost of the plant.

It's cheaper than solar panel and gives electricity at night

It's cheaper than solar panel and gives electricity at night

I described a new (3rd) class of solar power plants (in addition to solar panels and traditional CSP) and formulated the goals that we must achieve

Now we see solar energy which is reflected from this mirror, and focused in this way, and this receiver converts solar energy into water steam. It is a prototype of one of my solar heaters. My goals are described by this formula, which leads us to the cost of solar heat at the level of 0.5 cent / kWh, and it is approximately 10 times cheaper than the cost of heat from natural gas. In addition, this cheap thermal energy can be used to generate solar electricity which is cheaper than electricity from thermal and nuclear power plants. The 2nd half of this video will describe how we can turn this thermal energy into electricity 24 hours a day, both during the day and at night.

This is the prototype of my 2nd idea for the production of very cheap solar heat. I remind you that such experiments are described in detail in other videos of my YouTube channel, and this 2nd idea aims at these goals which lead us to this cost of our solar heat, 0.5 cent / kWh.

Here we can see that the total construction cost of my mirror should be about 10 $ / sq. m. This is realistically achievable because my mirror consists of this mesh of steel rods worth $ 3, and this reflective film at a price of 25 cent / sq. m.

The mirror of my 1st idea is more expensive, and it is a mirror version of cheap stainless steel. The wholesale prices of these mirror sheets are less than 10 $ / sq. m. I remind you that I am aiming for this cost of my stainless mirror, about 15 $ / sq. m.

This is just the beginning of my experiments, which will be described in my future videos. I will also research and describe other types of mirrors for cheap solar heaters, and for example, now I am showing the idea of this American company. It is a balloon, made of this transparent film and this reflective film which focuses solar radiation. This is also a balloon, but it is very large and was proposed by this Austrian company. Its reflective film focuses solar radiation in this receiver.

This German idea is the 2nd example, and the basis of this mirror is cheap and long-lasting concrete. I plan to start experimenting with the cheapest option of similar concrete mirror in 2 months. This is the 3rd example of cheap mirrors, and I have been testing these mirrors at this my solar station for almost 8 years.

Of course, we know about traditional solar heaters for large solar power plants, and this is the 1st type of the traditional heaters. This is the 2nd traditional type of solar heaters, and this is number 3. This is type number 4, and now I am showing the fifth traditional solar heater type which is used by this new solar power plant in China.

Unfortunately, these 5 traditional types use very expensive mirrors and systems to turn them according to the movement of the sun across the sky. Their cost is about several hundred dollars per square meter, and it is 30 or 50 times more expensive than those cheap mirrors which I will research and describe in my future videos.

So, I propose the 2nd road to cheap solar electricity, which is parallel to the 1st road of these 5 traditional types of solar heaters. The 2nd road goes through experimental and economic testing of various types of extremely cheap mirrors and through maximum simplicity of our solar heaters. The simplicity gives us the following advantages: Low cost, Reliability, Small investment.

Which of the two roads is better, we can understand by similar formulas, and the winner will be the road that will offer cheaper thermal energy at the temperature we need. So, it is only competition, and I am not an enemy of these traditional ways, and I believe in their prospects and ability to win against solar panels.

In addition, we understand that I must find cheap options for such turns according to the movement of the sun. That is why I am looking for different options which are several dozen times cheaper than traditional ones, and i will describe them in my future videos.

The Rise Of Wind Power In The U.S.

The Rise Of Wind Power In The U.S.

In the past decade, wind power capacity has tripled, and it’s projected to double in the decades to come. Wind is now America’s top renewable source of electricity generation, and the domestic offshore industry is finally taking off, as major manufacturers debut ever larger and more powerful turbines. While the industry faces some challenges with permitting, public opposition from various interest groups, and the obvious intermittency issues, there’s no doubt that wind is poised to play a major role in the energy transition. The question is just how fast it will grow.

Nuclear power: why is it so unpopular? | The Economist

The meltdown at a nuclear power station in Fukushima, Japan, ten years ago stoked anxieties about nuclear energy. But nuclear is one of the safest, most reliable and sustainable forms of energy, and decarbonising will be much more difficult without it.
