Yakıt is a substance that can be burned to produce energy, typically in the form of heat or power. Common types of yakıt include fossil fuels like petrol, diesel, and natural gas, as well as renewable sources such as biofuel and ethanol. These fuels are essential for various applications, including transportation, heating, and electricity generation. The efficiency and environmental impact of yakıt vary significantly depending on its type. Fossil fuels are known for their high energy content but contribute to greenhouse gas emissions, while renewable yakıt options are generally more sustainable. The choice of yakıt plays a crucial role in addressing energy needs and environmental concerns.
