Renewable energy is becoming an inevitable trend in the context of increasingly depleted natural resources and complex climate change. Benefits of renewable energy not only helps reduce dependence on fossil fuels but also contributes to environmental protection. Energy also helps cut CO₂ emissions and promote sustainable development. Let's Green In Learn about the benefits of renewable energy through the article below!
1. What is renewable energy?
Renewable energy (also known as clean energy) is a sustainable source of energy and is the opposite of fossil fuels. They are exploited from natural elements that are constantly and almost endlessly renewable, such as the sun, wind, rain, or tides.
2. Types of renewable energy in Vietnam
In Vietnam, popular types of renewable energy include:
- Solar
- Wind energy
- Hydroelectric power
- Geothermal energy
- Biology energy
- Tidal energy
- Solid waste energy
3. Benefits of renewable energy
Nowadays, fossil energy is no longer preferred by people because of its toxicity. Instead, renewable energy is increasingly developed thanks to its practical benefits. Some of the benefits include:
- This is a green energy source, safe for the environment and helps to significantly reduce pollution.
- Can be continuously regenerated, no need to worry about depletion.
- Diverse in types, including wind, solar, tidal and many other sources.
- Extracted from nature without cost of raw materials.
- Long life, low cost for maintenance and repair.
- Helps optimize electricity consumption for households, businesses and factories, contributing to long-term cost savings.
4. Harmful effects of renewable energy
Known for its great benefits to the environment and the economy, renewable energy also has its disadvantages. Some of the disadvantages include:
- Limited capacity: Despite rapid growth, renewable energy is still not enough to provide a stable source of electricity for the world. As energy demand continues to rise, scaling up and improving the efficiency of clean energy sources becomes a major challenge.
- High initial costs: Deploying renewable energy systems requires a large amount of capital. For example, installing solar panels or wind turbines requires a significant investment, making it difficult for many individuals and small businesses to access.
- Ecosystem Impacts: Renewable energy projects, such as wind farms and solar power plants, can negatively impact local flora and fauna. Noise from wind turbines, changes to the natural landscape, or large-scale land acquisition can reduce biodiversity.
- Weather Dependence: One of the biggest challenges of renewable energy is that it cannot operate reliably in all conditions. Solar power output drops on cloudy days, while wind power depends on wind speed, making it difficult to ensure a constant supply.
To overcome these limitations, there is a need for strong investment in energy storage technology, optimization of extraction processes and combination of different energy sources to ensure long-term efficiency.
5. Trends in using renewable energy in Vietnam
Vietnam is witnessing strong growth in renewable energy, especially in the commercial and industrial (C&I) sector. To meet the growing demand, the electricity market offers a variety of access options:
Method 1: Off-site power purchase agreement (off-site PPA)
Businesses can sign long-term contracts with project developers to buy renewable electricity from large plants. PPAs help fix electricity prices, ensure a stable supply, and provide financial support for new projects. However, they carry financial risks and are not suitable for all businesses.
Method 2: On-site power purchase agreement (on-site PPA)
Businesses can install solar power systems on their roofs or on their premises for direct use. This is the optimal solution for large-scale units, helping to save operating costs and reduce emissions. However, the installed capacity is often not enough to meet the entire electricity demand.
Method 3: Renewable Energy Certificate (REC/EAC)
Since it is difficult to determine the source of renewable electricity in the grid, businesses can buy RECs (renewable energy certificates) to ensure that the electricity they use is green. This is a flexible method, suitable for companies that want to achieve sustainable development goals without investing in infrastructure.
Method 4: Green Electricity Program from Utility Provider
Many electricity providers have implemented green tariff programs that allow customers to choose clean power from the grid. Although limited by region, this model is attracting many businesses that want to use renewable energy without having to install their own systems.
Each method has its own advantages and disadvantages, depending on the needs and conditions of each business. The trend of combining multiple solutions is becoming more and more popular to optimize costs and efficiency of renewable energy use.
