Ethanol, commonly known as alcohol, is more than just a recreational beverage; it’s also an important fuel and chemical feedstock. The energy content of ethanol is approximately 30.0 kJ/g.
This value indicates the amount of energy released when one gram of ethanol is completely combusted. Ethanol is often used as a renewable energy source and is blended with gasoline for use in vehicles. Its energy density, while lower than that of gasoline, makes it a viable alternative in certain applications.
It’s important to consider the energy balance of ethanol production and use, including factors like agricultural inputs and energy used in processing. Nonetheless, its relatively high energy content makes it a compelling option in the search for sustainable energy solutions.
