Biofuels are renewable energy sources made from organic materials, such as plants and animal waste. They can be used to power vehicles, heat homes, and generate electricity. Common types of biofuels include ethanol, which is often made from corn or sugarcane, and biodiesel, produced from vegetable oils or animal fats. These fuels help reduce greenhouse gas emissions and reliance on fossil fuels. The production of biofuels can also support local economies by creating jobs in agriculture and energy sectors. However, there are concerns about land use and food supply, as growing crops for fuel can compete with food production. Balancing these factors is essential for sustainable energy solutions.
