Petroleum and coal have long been essential energy sources in the industrial sector. Unfortunately, both have harmful effects on the environment, as their combustion contributes to rising global temperatures and widespread environmental damage.
Given the alarming consequences of relying on petroleum, it’s time for us to become more aware and start turning to cleaner, more sustainable energy alternatives. Want to know the best solution? Let’s explore in this article.
Cleaner Energy Alternatives to Petroleum
In addition to their negative impact, petroleum and coal are non-renewable resources. That’s why, to move toward a cleaner and more sustainable energy future, we need to transition to alternative energy sources.
Today, there are five major cleaner and more environmentally friendly energy options:
1. LNG
LNG, or Liquefied Natural Gas, is natural gas that has been cooled to around -162°C, turning it into a liquid form that is easier to store and transport.
LNG produces significantly less carbon dioxide (CO₂) emissions compared to burning petroleum or coal. It also has a high energy content, making it an efficient fuel for power generation.
LNG is often referred to as a bridge fuel in the energy transition from fossil fuels to renewable energy sources.

2. Solar Energy
Solar energy works by converting sunlight into electricity using solar panels. This technology can be used on both household and industrial scales.
Solar power offers many advantages—it’s abundant, renewable, and produces zero emissions during use. Plus, Indonesia receives ample sunlight year-round, making it a highly viable energy source.
3. Wind Energy
Wind is another renewable energy source that can be harnessed to power turbines. Wind turbines convert kinetic energy from the wind into electricity. This process produces no emissions and is especially efficient in windy areas.
Many developed countries have already adopted wind power as a major part of their energy mix. Meanwhile, in developing countries like Indonesia, wind energy remains underutilized.

4. Bioenergy (Biofuels and Biogas)
What we often consider waste can actually be a valuable energy resource. Bioenergy is derived from organic materials such as crop residues, agricultural waste, animal manure, and even household organic waste.
There are two types of bioenergy: biofuels and biogas. Biofuels are liquid fuels made from biomass, while biogas is produced through anaerobic fermentation (without oxygen) of organic materials like manure and agricultural waste.
5. Hydropower (Hydroelectric Energy)
Hydropower generates electricity by harnessing the energy of flowing water—typically from dams—to spin turbines. These turbines then convert kinetic energy into electricity.
However, the use of hydropower must be managed carefully to avoid disrupting river ecosystems. Conducting Environmental Impact Assessments (EIA) and developing micro-hydro systems without building large dams are some sustainable approaches to using water as an energy source.

Why LNG Is the Best Current Solution?
Among the various alternative energy sources available, LNG is considered the most viable solution for the present—especially in supporting the global energy transition.
While renewables like solar and wind hold great promise, they also come with significant challenges.
Both sources rely heavily on weather conditions and time (daylight availability), and typically require large-scale infrastructure to operate efficiently.
On the other hand, LNG provides a more stable energy supply and emits significantly less CO₂ than coal and oil.
With well-established infrastructure, a nationwide distribution network, and supportive regulations, LNG presents a practical bridge for Indonesia in achieving a cleaner and more sustainable energy future.
