Non-renewable energy has always played an extremely important role in the development of all mankind. However, facing the risk of this energy source being over-exploited and leading to a gradual depletion, what should people do? To solve this problem, let's GREEN IN Learn about non-renewable energy and sustainable alternatives through the article below!
1. What is non-renewable energy?
Non-renewable energy is understood as energy sources that are directly exploited from nature, including coal, oil, minerals, uranium and other similar sources. They are scattered all over the planet. Due to the formation process lasting from millions to hundreds of millions of years, these energy sources cannot be quickly regenerated. This means that, over time, they will gradually be exhausted and cannot be restored.
2. Non-renewable energy sources that exist on Earth
Currently, non-renewable energy will be classified into two main energy groups including:
2.1. Fossil energy
Fossil energy is an energy source that is directly exploited from minerals and fossils deep within the Earth, including:
- Petroleum: Is a decisive energy source for human survival and development when it is gradually applied in all fields from industry, electricity production, energy, chemicals or transportation.
- Coal: This is an energy source mined from underground and used by burning, coal creates heat energy for industrial production activities.
- Natural Gas: Composed of hydrocarbon compounds, natural gas is extracted from oil and gas fields to meet energy and production needs in many fields.
2.2. Nuclear energy
Nuclear energy is classified as non-renewable energy. During the nuclear reaction, radioactive substances such as Thorium or Uranium-235 are used to produce a huge source of energy. Although the process of creating nuclear energy does not produce greenhouse gases, limiting the impact on the environment, the important issue when producing this energy source is the process of handling waste and nuclear waste to ensure safety.
3. Advantages and disadvantages of non-renewable energy
3.1. Advantages
Fossil energy
- Fossil energy is a naturally available energy source, so the exploitation and use process is extremely quick and convenient.
- Easy to transport, exchange and buy and sell.
- Fossil energy has played an undeniable role in industrial revolutions from past to present.
- Humans today can make the most of fossil energy sources thanks to the remarkable development of technology.
Nuclear energy
- The production of nuclear fuel appears to emit very little greenhouse gases when compared to fossil fuels, thereby minimizing negative impacts on the environment.
- Nuclear reactions have the potential to provide far more energy than other energy sources. For example, with the same volume of fuel, the energy produced by nuclear reactions can be many times greater than that of natural gas or oil.
3.2. Defect
Fossil energy
- This is a completely exhaustible and non-renewable energy source if not exploited and used properly.
- Using fossil energy can produce large amounts of CO2, thereby making environmental pollution and the greenhouse effect increasingly serious.
- Burning fossil fuels also produces sulfur dioxide - the cause of acid rain, which negatively affects human health and the natural environment.
Nuclear energy
- Nuclear energy leakage is an extremely terrible accident, negatively affecting human health and the environment surrounding the leak area.
- The cost of building a nuclear plant is enormous.
4. Distinguish between renewable energy and non-renewable energy
When distinguishing between renewable energy and non-renewable energy, you need to understand these two concepts. If non-renewable energy has been explained above, then renewable energy according to Article 43 of the Law on Environmental Protection 2014 is: "Renewable energy is energy exploited from water, wind, sunlight, geothermal energy, ocean waves, biofuels and other renewable energy resources."
| Criteria | Recycled energy | Non-renewable energy |
| Short-term and long-term vision | Long-term vision, environmental protection and resource saving. | Short-term vision, quick exploitation with little regard for long-term impact. |
| Sustainability | Highly sustainable, helping to reduce negative impacts on the environment. | Low sustainability, causing many negative impacts on the environment. |
| Renewability | Capable of rapid and continuous regeneration. | Cannot regenerate or regenerates very slowly. |
5. Non-renewable energy alternatives for businesses
Replacing non-renewable energy with renewable energy in manufacturing plants not only helps businesses save costs in the long term, but also contributes to minimizing negative impacts on the environment. Using renewable energy helps businesses enhance their reputation and sustainable image, while creating opportunities to improve production efficiency through the application of green technologies. This not only brings economic benefits but also promotes long-term sustainable development, helping businesses prepare for changes in global consumer trends and environmental protection policies:
- Solar energy: Installing a rooftop solar power system is one of the most popular renewable energy models today, not only providing an abundant source of electricity for the business but also reducing the burden on the national grid during peak hours. This solution is suitable for businesses with the advantage of large rooftop space.
- Wind Energy: Using wind turbines in strategic locations near factories and large buildings can help make the most of areas with strong and stable wind speeds.
- Bioenergy: Utilizing waste generated during the production process, converting them into energy sources through biodegradation to provide energy for the operations and production of industrial plants.
- Heat recovery system: Utilizes waste heat from the production process to convert it into heat or electricity, thereby minimizing costs and optimizing energy use.
