India's 20% Ethanol Blend Fuels Global Alternative-Energy Search

Most of the fuel used in cars comes from oil that formed deep underground millions of years ago.

But oil will not last forever, so people are looking for new ways to power machines.

In India, petrol now has 20% ethanol mixed into it.

Ethanol is a fuel that can be made from plants like sugarcane, corn, and extra grain.

This helps India buy less oil from other countries and gives farmers new customers.

Ethanol absorbs water from the air, which can sometimes cause problems in fuel tanks, so it is tested very carefully.

Scientists are making other strange fuels too, like jet fuel from used cooking oil.

Some fuels come from algae growing in ponds, which make lots of oil without using farmland.

People have even tried making fuel from coffee, beer, chocolate, and instant noodles.

In the future, there may not be one single fuel, but hundreds of different ideas working together.
