Yes. Vegetable oils are used to make bio diesel, which can be used like conventional diesel. Vegetable oils are also used to make biodiesel, which can be used like conventional diesel. Some vegetable oil blends are used in unmodified vehicles but straight vegetable oil, also known as pure plant oil, needs specially prepared vehicles which have a method of heating the oil to reduce its viscosity. The vegetable oil economy is growing and the availability of biodiesel around the world is increasing. The NNFCC estimate that the total net greenhouse gas savings when using vegetable oils in place of fossil fuel-based alternatives for fuel production, range from 18 to 100%. source: Wikipedia

The question how do I make ghee is quite common among cooking enthusiasts. Here's the process: Melt the unsalted butter in a saucepan at medium heat for 20-30 minutes. Allow the butter to boil and continue to cook, occasionally stirring, until it begins to foam. As the foam rises to the top, the butter will turn a golden color, and you will begin to see tiny brown specks forming at the bottom of the pan. This is the milk solids separating from the fat. Reduce the heat to medium-low and keep stirring occasionally, until the butter turns a deep golden color and the milk solids at the bottom of the pan are a rich brown color. Remove the pan from the gas and let it cool for a few minutes to allow any remaining solids to sink to the bottom. Carefully pour the ghee through a fine-mesh strainer or cheesecloth-lined sieve into a clean glass jar or container, leaving the solids behind. Allow the ghee to come to room temperature before sealing the jar or container and storing it in the pantry or refrigerator. Note: Be careful not to let the ghee burn, as it will taste bitter. Using a heavy-bottomed saucepan or pot is also essential, as it will help distribute the heat more evenly and prevent the ghee from burning. I hope this help ! milkio.co.nz/how-do-i-make-ghee/
