Why is biogas is regarded as a better fuel than cow dung cake?

Biogas is considered a better fuel than cow dung cake because it has a higher energy content and burns more efficiently, producing less smoke and harmful emissions. Additionally, biogas can be produced from various organic materials, making it a more versatile and sustainable energy source. Its use also contributes to waste management by reducing the volume of organic waste. Furthermore, biogas systems can capture methane, a potent greenhouse gas, thus helping to mitigate climate change.
