What Is Biofuel? — Reading Comprehension

Biofuel is a type of renewable energy made from things that were once alive. It is a fuel created from plants, vegetable oils, and 

. Because it comes from natural materials, biofuel is a cleaner alternative to fossil fuels like gasoline and diesel.

Biofuel stores energy from the sun. Plants absorb sunlight and turn it into energy through a process called photosynthesis. When these plants are turned into fuel, they release that stored energy to power vehicles and machines. This makes biofuel a smart way to use the energy that nature provides.

There are two main types of biofuel: ethanol and biodiesel. Ethanol is usually made from corn or sugarcane and is often mixed with gasoline to power cars. Biodiesel is made from vegetable oils or animal fats and can be used in trucks and buses.

Biofuels are helpful because they can be made again and again using crops and natural waste. They produce fewer greenhouse gases than fossil fuels, which helps protect the environment. Many countries use biofuels to lower pollution and reduce their need for oil.

However, there are also challenges. Growing large amounts of crops for fuel can use up valuable land and water. It can also affect food prices if crops are used for fuel instead of food. That’s why scientists are working on new ways to make biofuel from waste materials and non-food plants.

Biofuel is one way people are using science and nature to create a sustainable future. It shows how living things can help us meet our energy needs in a cleaner, renewable way.
