Amidst global concern about climate change and high dependence on fossil fuels, the search for renewable energy solutions is increasingly urgent, including bioethanol . Bioethanol, as a promising renewable energy source, appears as an alternative fuel.
The following are some of the benefits of bioethanol as a renewable energy source that can bring changes to society and the environment.
1. Fuel Economy and Performance
Quoted from the US Department of Energy the impact of bioethanol on fuel economy varies depending on the difference in energy in the mixture used. For example, E85 which contains 83 percent ethanol content has about 27 percent less energy than gasoline.

The impact on fuel economy decreases as the ethanol content decreases. If optimized to use a higher ethanol blend, fuel economy will likely improve as a result of increased engine efficiency.
Ethanol also has a higher octane number than gasoline, which provides increased power and performance. For example, racers often refuel their race cars with E98 because of its high octane. The Co-Optimization of Fuels and Engines initiative examines the potential for increasing engine efficiency through the use of blends of ethanol and other high-octane biofuels.
2. Opening Job Fields
Ethanol production creates jobs in rural areas that need job opportunities. According to the Renewable Fuels Association, ethanol production in 2021 will account for more than 73,000 direct jobs nationwide.
3. Reducing Greenhouse Gas Emissions
One of the main benefits of bioethanol is its ability to reduce greenhouse gas emissions. When burned, bioethanol produces carbon dioxide emissions, but the amount is much lower than fossil fuels such as gasoline or diesel.

Plants that are used as bioethanol feedstock, such as corn or sugarcane, also absorb carbon dioxide during their photosynthesis, helping to reduce the concentration of greenhouse gases in the atmosphere.
4. Energy Independence
Bioethanol offers hope to meet domestic energy needs without depending on imported fossil fuels. By relying on renewable bio-resources, countries can build greater bioethanol production capacity and increase overall energy sustainability.
