If you thought running your car requires some serious home budgeting imagine what an airline goes through when managing its jet fuel costs. Boeing recently flew a plane that was powered by a hydrogen battery. The plane, which used propellers, flew at a speed of 100 kilometers (62 miles) an hour for about 20 minutes at an altitude of about 1,000 meters (3,300 feet) using only the hydrogen battery for power. Amid rising fuel costs and mounting concerns over climate change, airlines are keen to find ways to cut their energy bills and the pollution, which they emit.

Boeing’s first new model in over a decade, the Dreamliner, used high-tech composites which reduces its weight and which the company says will make it consume 20 percent less fuel then similar-sized planes already on the market. Seems the every business is attending to the environmental issues it ignored and contributed for a long time.
