Nowadays, oil is a big problem. All costs depend on oil price so much.If there is a changing price, it will make another product price will be changed.For example, there is a 10p increasing oil price->produce cost increase-> product price goes up.
Oil is not unlimmited. We used it a long time, it will be over in one day in future. Scientists are looking for new fuel to replace, but now they are too expensive and not popular.
Green fuels are the best fuel to repalce for oil because they don't make pollution and we have them already.Israel is a country which produce a lots oil every year.If it goes first, I think it will make another countries follow.
Anyways, it will be a growth and popular industry in future.It a good idea. Now we can think it is a adventure, but when it grow up.I will be a high profitable business...
