Source of energy for the whole people
Solar power is called all-people energy reflecting the simplicity of integrating solar power into the residential power supply system in parallel with the grid or electricity from other sources.
|Clean, inexhaustible, and widely exploitable in all regions of the earth are the advantages of renewable energy.|
Renewable energy: Seeing from reality
The era of science and technology has established many miracles for humanity. Civilized countries have developed many years before, affirming that solar power is a positive development trend in providing energy for personal and public needs with many advantages. The most outstanding is the renewable ability of this energy source.
Solar energy production has advantages over hydroelectric, thermal, or wind power. By not using internal motors such as generators, electricity generation is noiseless and can be produced on a household scale.
The scope of application of this type is also vast, such as supplying electricity in areas not connected to the national grid, seawater desalination in many African countries that lack freshwater, and even powering satellites in earth orbit.
|Renewable energy development is an inevitable and irresistible step.|
According to Mr. Fatih Birol, IEA Director, promoting investment in clean energy will bring many advantages and opportunities, including expanding access to power, creating jobs, developing industries, improving energy security, and creating a sustainable future for all.

According to the International Energy Agency (IEA) and the International Finance Corporation (IFC), a member of the World Bank, today's clean energy is evolving rapidly. Investment is critical to helping countries benefit from a clean energy economy.
One hundred thirty years of coal power & 95 years of hydroelectricity in Vietnam, but it still cannot be called "all-people energy."
In February 1894, the French built the Flower Garden Lamp House - Vietnam's first coal power plant in Hai Phong. The other two hydroelectric plants, Ta Sa and Na Ngan, were constructed in 1927-1928 during French colonial exploitation for the second time.
The source of raw materials for thermal power is mainly coal - a fossil fuel with large reserves in areas such as China, India, and the US. However, coal is a dirty, non-renewable fuel that produces greenhouse gas emissions in the process of combustion.
The IEA is concerned about the environmental impact of burning fossil fuels. Factories using this source of raw materials cause the emission of pollutants such as NOx, SOx, CO2, CO, PM, organic gases, and polycyclic aromatic hydrocarbons, which increase acid rain and air pollution and are directly related to global warming.
|Thermal power plants are one of the sources of toxic gases and particulate pollution.|
In addition, a study published in August 2010 found that coal slag from thermal power plants contained pollutants, including arsenic, and has been linked to respiratory diseases and other health and development problems that have disrupted local aquatic life.
Coal is the remains of the earth's crust that also contain low levels of uranium, thorium, and other naturally occurring radioactive isotopes. A 1,000MW coal-fired power plant can release up to 5.2 tons of uranium and 12.8 tons of thorium annually.
Hydropower "kills" hydrology
Today, in the context of technology making great strides, scientists and environmental researchers also confirm that hydroelectricity is no longer a clean and cheap source of energy. This has been proven from practice with the amount of forest area lost or the number of households whose lives have been disturbed to serve the development of this power sourced recently.
The thing to be concerned about is the hot and dense development of small and medium hydro powers is leading to the destruction of river basins, blocking the natural flow downstream. Especially when the delta area is no longer filled with alluvium, our country will lose its advantage in agricultural development.
"Under the sun, everything is revealed"
Increasingly, scientists and environmental research organizations have discovered many exciting things from the utility and advantages of solar power. And the name "all-people energy" is a modern definition, precisely like the nature of this type of energy.
|Solar power, "Energy for the whole people," an undisputed definition.|
It is not too difficult for the era of 4.0 - 5.0 to completely overcome the limitations of solar power, that is, limited capacity at night or on cloudy and rainy days. After all, wind power and solar power still have more advantages. Hence, energy security needs to be adequately understood, sufficiently, and wisely by EVN to overcome and, at the same time, promote the benefits of each type of energy.
"Emerging and developing economies have huge potential for clean energy, but the level of investment is far below what is needed. To address pressing energy needs and emission reduction targets in these economies, we need to mobilize private capital rapidly and urgently develop many projects. Projects can be more investable", emphasized Makhtar Diop, Director of IFC.
