The increasingly serious climate change is a matter of global concern. This is also the reason why many countries, organizations and businesses choose to use renewable energy as a perfect alternative solution. Renewable energy is considered the most rapidly growing energy source in the world today. However, to be able to use this type of energy effectively, you need to apply appropriate renewable energy technologies. Let's GREEN IN Learn about popular renewable energy technologies through the article below!
1. Overview of renewable energy
Renewable energy is defined in Clause 1, Article 43, Law on Environmental Protection 2014 (out of force): “Renewable energy is energy exploited from water, wind, sunlight, geothermal energy, ocean waves, biofuels and other renewable energy resources.”
Although the legal document is no longer in effect and has been replaced by the Law on Environmental Protection 2020 (the concept of renewable energy is not mentioned in this law), from the old document, you can also understand that renewable energy is an energy source that is exploited from nature and can be self-renewable.
Natural phenomena that are never exhausted such as the sun and wind are the raw materials for producing renewable energy. This characteristic is the premise for renewable energy to become an ideal solution to meet the global energy demand without causing negative impacts on the environment. Thanks to the use of renewable energy, the situation of climate change is not only improved by reducing greenhouse gas emissions but also brings many investment and business opportunities for people.
2. Renewable energy engineering technology
Renewable energy technology is the field of research and application of solutions to convert and effectively exploit renewable energy sources such as solar, wind, water, geothermal, biomass, etc. to meet the demand for energy without causing negative impacts on the environment. Some prominent technologies in this field include:
- Solar energy: Uses solar panels to absorb light and convert it into electricity.
- Wind energy: Wind turbines collect energy from the wind, then convert it into electricity to serve people's daily life and production.
- Hydropower: Uses water flow or pressure to rotate turbines, which can generate electricity.
- Geothermal energy: Harnessing heat from the earth to generate steam for electricity production or heating.
- Biomass energy: This energy source is produced by using organic materials such as wood, agricultural waste, and biological waste to generate heat or electricity.
- Biogas energy: Converts organic waste into methane gas, used to generate heat or electricity.
These technologies are being improved and widely applied globally to reduce greenhouse gas emissions, protect the environment and contribute to the fight against climate change.
3. Renewable energy technology is commonly used today
3.1. Technology to store solar energy for a long period of time
One of the most notable renewable energy technologies is the storage of solar energy for a long period of time. After a long period of research, the invention of a battery that can store solar energy for up to 18 years has been put into circulation.
This research not only helps to overcome the problem of unstable solar energy at night or when the weather is cloudy, but also opens up the prospect of developing self-charging devices that use solar energy on demand. This promises to bring a more flexible and efficient solution in exploiting and using renewable energy from the sun.
3.2. Technology using sunlight to develop next generation materials
The use of light technology to develop next-generation materials is a promising research direction. Thanks to advanced machine learning systems, scientists can now simulate and predict the effects of light on materials at the atomic level. This opens up opportunities to create more energy-efficient and high-performance materials.
These technologies can be widely applied in areas such as sensing, data storage and energy, providing smart and economical solutions in light harvesting.
3.3. 3D printing technology for manufacturing components in wind turbine towers
3D printing is also revolutionizing the wind turbine industry. It allows for flexibility in increasing the size of turbine towers while reducing shipping costs, allowing manufacturers to create large, solid concrete foundations that improve turbine performance and expand wind energy capabilities. It also creates new jobs and reduces environmental impact.
