14 billion years have passed since the Big Bang took place and the universe came into being. The solar system is 5 billion years old. This is the scientific point of view of scientists. But no matter how this process took place, no matter how many periods it covered, it is true that nature and life on our mother earth came into being because of the rays of the Sun. From the creation of fire by man, however, the progress of mankind has entered a new era. From time immemorial, these two sources have been the source of life and warmth for mankind on any given day. Over the centuries, our lives have been enriched with energy sources such as coal, electricity, oil, gas, and nuclear. The 21st century is a period of alternative and renewable forces.

"Green" energy is a structure that provides energy without the use of fossil fuels, does not emit CO and CO2 into the atmosphere and, consequently, does not harm the environment. At the same time, consumer demand is met by alternative energy sources such as solar, wind, water, biomass, hydrogen energy.

What about the world’s alternative energy?

In 2020, a world record was set for the introduction of alternative energy, with more than 200 GW of capacity commissioned. According to BloombergNEF, despite the fact that the world is experiencing a coronavirus pandemic, this result was achieved due to large investments in the solar and hydrogen transport networks. In particular, $ 150 billion has been invested in solar energy, which is 12% more than in 2019. Analysts say the record will be updated again this year. The new solar and wind power plants are expected to increase to 150-190 and 80-90 GWh, respectively.

European electricity is also becoming increasingly green, with more than two-thirds of total electricity generation last year coming from alternative sources. At the same time, the production of electricity from conventional fossil fuels has decreased by 18 percent. Denmark (61 percent of total production), Ireland (35 percent), Germany (33 percent) and Spain (29 percent) lead in the use of alternative energy.

It is well known that China is often referred to as a "heavenly" or "heavenly" country. He has proven this in practice, leading the world in the growth rate of "green" energy. Last year’s coranavirus disaster also failed to halt its rapid pace, and the number of ecologically clean power stations doubled. In total, China generated 800 GWh of alternative energy, twice as much as the United States, the world's second-largest economy.

Indeed, the rate of development of alternative energy in China is very high. But its share in total electricity volume rose to 15 percent last year. This is two to three times less than in developed countries. China's plan to increase its share of alternative energy to 25% by 2030 is in line with Uzbekistan's strategic goals.

"Sunny free land ..."

Our hymn begins with such warm verses, and there is no exaggeration in it. Because long-term observations of the network of actinometric stations in the country have shown that in our country 300-320 days a year can fully enjoy the generosity of the sun, radiating from 2400 to 3090 hours a year in different regions. Its annual capacity ranges from 509 to 760 billion kilowatt-hours, which is much higher than the available and explored hydrocarbon reserves. If we add up to 1 trillion kWh of wind, more than 21 billion kWh of hydropower, 6 billion cubic meters of biomass and hydrogen, the capacity of which has not yet been fully determined, our understanding of the potential of alternative energy is even richer.

However, until recently, when we talked about the "green" energy potential of our country, such large numbers were given, and when it came to practical work, it was unlikely to find an example that would fill the heart with pride. True, 130 kWh, 1.2 megawatts and other small solar power plants were built in the valley of Pop district, in the town of Kandym, Bukhara region. But their size was like a drop in the ocean.

Unfortunately, the project to build a 100 MW solar photovoltaic plant in Samarkand, which was presented in 2013, has caused quite a stir.
