how can we conserve petroleum?

Answer 1

How do you conserve petroleum?

There are a huge number of ways to conserve petroleum. This are just a few of the major ones. 
Don't leave lights on when you're not using them, or waste electricity in other ways. A fair portion of electricity is made by burning petroleum, so the less electricity we use, the more petroleum we save.Find ways to save gasoline. These can include walking or cycling, carpooling, or using public transportation. Electric and hybrid cars also save some petroleum (but remember, the electricity they use possibly had to come from a small amount of petroleum).Use products that are made, and foods that are grown and processed locally. Shipping foods and other goods uses up a tremendous amount of fuel. Also, certified organic food products don't use chemicals, whose production uses petroleum.Reduce the amount of packaging that you use by buying products with minimal packaging. This is because packaging is usually made of plastics (which are made of petroleum), and it requires energy (usually from petroleum or coal) to make packaging.
