In search of universal energy

According to NASA calculations, the Sun can provide us with energy for about 6.5 billion years. This energy source can be received and used everywhere in the world, not only near the Earth's equator but also at high latitudes in the Northern and Southern Hemispheres.

Solar power (SPP) is called “universal energy”, reflecting the simplicity of integrating SPP into the home electricity supply system, parallel to the grid or electricity from other sources.

Clean, inexhaustible, and widely available in all regions of the world are the advantages of renewable energy.

Renewable Energy: A Look at Reality

The era of science and technology has established many miracles for mankind, in which civilized countries have gone ahead for many years and affirmed that solar power is a positive development trend in providing energy for private 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. Because it does not use internal motors like generators, electricity generation does not cause noise and can be produced on a household scale.

The scope of applications for this type is also very wide - providing electricity in areas not connected to the national grid; used for desalination of seawater in many African countries with scarce fresh water, and even providing energy for satellites in Earth orbit.

The development of renewable energy is an inevitable step of humanity that nothing can resist.

Mr. Fatih Birol, Director of IEA, emphasized that promoting clean energy investment brings many advantages and opportunities, including expanding energy access, creating jobs, developing industries, improving energy security and a sustainable future for all people.

“I saw yellow flowers and green grass”.

According to the International Energy Agency (IEA) and the International Finance Corporation (IFC), a member of the World Bank, “ The world of clean energy is growing rapidly today. Investment is key to helping countries benefit from the renewable energy economy .”

130 years of coal power & 95 years of hydropower in Vietnam but still cannot be called "national energy"

In February 1894, the Vuon Hoa Lighthouse - Vietnam's first coal-fired power plant was built by the French in Hai Phong. The two hydroelectric plants named Ta Sa and Na Ngan were built from 1927-1928 during the second colonial period of French colonial exploitation.

The main source of fuel for thermal power is coal - a fossil fuel with large reserves in politically stable regions such as China, India and the US. However, coal is an impure, non-renewable fuel and during the burning process, it creates greenhouse gas emissions.

The International Energy Agency (IEA) is concerned about the environmental impact of burning fossil fuels. Factories using these fuels emit pollutants such as NOx, SOx, CO2, CO, PM, organic gases, polycyclic aromatic hydrocarbons, which are agents that increase acid rain, air pollution and are directly related to global warming.

Thermal power plants are one of the sources of toxic gases and polluting particles.

Additionally, a study published in August 2010 found that coal ash from thermal power plants contained contaminants including arsenic and lead linked to respiratory illnesses and other health and developmental problems, disrupting local aquatic life.

Coal is a remnant of the earth's crust that also contains low levels of uranium, thorium and other naturally occurring radioactive isotopes. A 1,000MW coal-fired power plant can release up to 5.2 tonnes of uranium and 12.8 tonnes of thorium each year without control.

Hydropower kills hydrology

Nowadays, when technology is making great strides, scientists and environmental researchers still affirm that hydropower is no longer a clean and cheap source of energy. This has been proven in practice when the amount of forest area lost, or the number of households whose lives have been disrupted to serve the development of this power source in recent times.

What needs to be concerned here is that the rapid and dense development of small and medium hydropower plants is leading to the destruction of river basins, blocking natural flow downstream. In particular, when the delta area is no longer silted up by alluvium, our country will lose its advantage in agricultural development.

“Under the sun, everything is exposed”

More and more, scientists and environmental research organizations have discovered many interesting things about the convenience and advantages of solar power. And the name "energy for the people" is a modern definition, exactly as the nature of this type of energy.

DMT "Energy for all people" is an indisputable definition.

It is not too difficult for the 4.0 - 5.0 era to completely overcome the limitations of solar power, which is limited in capacity at night or on cloudy and rainy days. After all, wind power and solar power still have many advantages, so EVN needs to understand energy security correctly, sufficiently and wisely to overcome it, while promoting the advantages of each type of energy.

“ Emerging and developing economies have huge clean energy potential, but investment levels are far below what is needed. To address their urgent energy needs and emissions reduction targets, we need to mobilize private capital at speed and scale and urgently develop more bankable projects,” said Makhtar Diop, IFC Country Director.
