The increasingly evident climate crisis has made the need to transition to more environmentally friendly energy sources more urgent than ever. One renewable energy source that has gained significant attention is bioenergy.
This type of energy has tremendous potential because it comes from organic materials that are relatively easy to find and can be renewed sustainably.
But with this potential, can bioenergy truly challenge the dominance of today’s fossil fuels? Let’s find the answer in this article.
What Is Bioenergy?
Bioenergy is a type of energy derived from biomass, which refers to organic materials that can be converted into energy. This biomass includes various sources such as:
- Plants (e.g., wood, agricultural waste, algae)
- Organic animal materials (e.g., livestock manure for biogas)
- Various organic waste that can be processed further
Bioenergy is classified as renewable energy because the raw materials can be produced sustainably through natural processes like plant growth or organic waste processing.
With proper management, biomass can become a stable energy source while reducing dependence on fossil fuels.

How Does Bioenergy Work?
Bioenergy works differently depending on the type of biomass used, but the basic principle remains the same: converting the chemical energy stored in organic matter into usable energy.
Here are the three main mechanisms of bioenergy conversion:
- Direct combustion: burning solid biomass, such as wood pellets or agricultural waste, to generate heat and steam that drive power turbines.
- Thermochemical conversion: processes like gasification or pyrolysis that convert biomass into synthetic gas (syngas) or bio-oil.
- Biochemical conversion: using microorganisms to break down biomass, such as fermentation to produce bioethanol or anaerobic digestion to generate biogas.

What Are the Types of Bioenergy?
Bioenergy comes in several forms, classified based on its final output and application in the energy sector.
Here are the most commonly used types:
- Solid biomass: used for power generation, industrial heating, and household needs. Examples include wood pellets, briquettes or biochar, and agricultural residues.
- Liquid biofuels: used in the transportation sector. Examples include biodiesel from palm oil and bioethanol from crops like sugarcane or corn.
- Biogas: produced from the decomposition of organic waste and animal manure, and used for electricity generation or household heating.
Bioenergy is widely utilized in industries, transportation, and electricity generation.
This demonstrates its potential to reduce reliance on fossil fuels and support the transition toward cleaner energy.

What Are the Benefits of Bioenergy in Industry?
Bioenergy offers positive impacts on the environment, economy, and energy security. Here’s a detailed explanation.
Renewable Energy Reserves
Bioenergy is a renewable energy source that can be produced sustainably through the cultivation of energy crops or the utilization of continuously generated organic waste.
With these characteristics, bioenergy helps reduce pressure on limited fossil resources and supports the transition toward a more sustainable energy system.
Reduced Carbon Emissions and Waste
Bioenergy has the potential to be nearly carbon neutral if biomass is grown, harvested, and managed sustainably.
The carbon dioxide released during combustion can be reabsorbed by newly grown plants through photosynthesis, helping balance the carbon cycle.
Moreover, using organic waste as biomass reduces waste buildup and prevents methane emissions from landfills.

Strengthening National Energy Security
The development of local bioenergy, such as palm-oil-based biodiesel, can significantly improve national energy resilience.
Using biodiesel reduces dependence on imported diesel, which has volatile prices, strengthens the trade balance, and improves domestic energy supply stability.
New Economic Opportunities
Bioenergy can create a new value chain that drives economic opportunities and opens jobs, especially in agriculture, waste processing, and biorefinery technology.
Its development also supports energy decentralization through the use of local resources, contributing to regional economic growth, particularly in rural biomass-producing areas.

Can Bioenergy Replace Fossil Fuels?
Bioenergy cannot yet replace fossil fuels entirely, but it holds significant potential to take over part of their role, especially in supporting the transition to cleaner energy.
Currently, global bioenergy contribution remains limited, making up only a small portion of total world energy consumption.
The availability of biomass, organic waste, and vegetable oils is still insufficient to meet massive energy demands due to feedstock regeneration challenges and land-use competition.
Additionally, bioenergy infrastructure and logistics are not as mature as fossil-fuel supply chains, which have been established for decades.
In today’s landscape, it remains challenging for bioenergy to become the primary energy source. This is why alternatives like LNG (Liquefied Natural Gas) are gaining traction.
LNG infrastructure and distribution in Indonesia are relatively developed, allowing it to reach areas where gas pipelines are unavailable.
Compared to coal and petroleum, LNG is a cleaner option because its combustion produces significantly lower CO₂ emissions and air pollutants, and it generates almost no particulates or ash.
