Why is alternative fuel better?

Alternative fuels can be better in that they are generally cleaner than oil and gasoline. Most alternative fuels are renewable, which means there can be a steady supply for a long time. Oil is not renewable.

Development of new alternative fuels also can fuel the economy and new jobs. Alternative fuels have the potential to replace the oil economy, it is just a question of if the fuel can be produced efficiently and be sold at a practical price for people.
