Blog # 6 Renewable energy vs coal and diesel

The time is coming when the world will be out of fossil energy, and if something isn't done we'll be in the dark ages.  The world lives off of finite fuels such as coal, and oil, and what will happen when it's all gone are at very limited supply?  In the article, it discusses that we need to be looking for and using renewable sources of energy.  Energy Sources such as, solar and hydro-power, but what about fuel for cars or transportation?  The article seem to state that the answer to these problems is the production of bio-fuels, from the crops.  Crops are very renewable, and can produce new fuel alternatives for finite fuel supply's.  But the problem that arises is that if you start converting crops to fuel, that would be used for food, then what do you do for food?  The production of crops for food and and fuel would take place and which would out weight the other?  The article states that we would be reluctant to switch because first of all the world is has a limited food supply as it is, and then to convert things to run these new fuels would require, more work than one my want to put forth, when at the moment its cheaper to put a fossil fuel into what ever it is and run it that way.  I think that this is great, and that using alternative uses for fuel and renewable resources, is the way of the future.  But the problem is that i see is, its going to take something really drastic to get people of the world involved in this.  All is good when the price for fuel goes down, what if the price in food goes up?  On a side note, for the world this will be a problem, but for the US, i think its time that we start eating less, and mabey if we can do that alot of things will start to work out for the good.  So over all the need for alternative, renewable resources is great, but what if it comes with a price?
