Transportation
Transportation represents 19% of the world's total energy needs. When light aluminum and other materials are used in buildings, energy consumption can be reduced.
When the weight of the vehicle is reduced, the energy consumption in transit is also reduced.
It's some kind of transportation. Aluminum helps to reduce weight:
automobile
Bus
Truck
aircraft
Train
Each saves 100 kilograms of weight and can reduce fuel consumption by 800 litres.
There is a large number of cars in the world. This allows the low weight car to become the largest potential for reducing global energy consumption.
A car has 40% recycled aluminum, a lifetime energy savings, 680 liters of gasoline and a lifetime savings of 1950 kg of carbon dioxide emissions.
Aluminum has been widely used in aircraft. The weight loss of aircraft is less than 1 kg, which is equivalent to 1000 times the effect on passenger cars.
If we want to replace the current car with the new (light) fleet from the existing model, this will reduce the world's fuel consumption from the car by 7.5%. If we continue to explore potential, reduce weight, the car, so that can reduce this figure 3.1%.
