Most people by know more than likely know who Dr. Marion King Hubbert was. The Shell Oil geologist that predicted that the US production of oil would begin to peak in 1970's and if you lived in the 1970's you all know what happened, a gas shortage, which of course means that he was right. It was also predicted by Hubbert that the global supply would peak in 1995. Now it seems according to officials that the global oil reserves are getting harder to get to and it's of a lower grade now and the volume is not meeting the demand of the world. Well, with all of this going on, there is something you can do yourself to stop depending so much on those fossil fuels.
You can either buy yourself a diesel car since a diesel engine does not run on fossil fuels but uses biodiesel fuel which is made from a combo of fossil fuels and non-fossil fuel based items or is made completely out of non-fossil fuel based ingredients. If you already have diesel engine then you should already be able to use the biodiesel fuels being produced and you can now find this fuel in all gas stations all over the country now. You could also consider going hybrid if biodiesel doesn't interest you.
Try and go solar in your home and reduce your dependence of fossil fuel. Try and convert the power you use in your home from fossil fuels to solar power. Solar power of course can be expensive to install but as it starts to grow in popularity the price will lower. You can go step by step gradually converting your home until you have completely converted your home to a photovoltaic system that will run your entire home with solar power.
Consider trying to get a job where you can work from home. If you already have a job that it away from home, especially if it's an office job, see if you can't arrange with your employer for you to work from home. This will help you to use far less fuel by not needing to have to commute to work each day. If your boss is not too keen on the idea try asking him to let you try it part time and if he likes the way things go then move to full time telecommuting.
Grow your own organic garden if you have the room for it. If not, consider trying to grow your garden in containers. By growing your own garden you'll be cutting down on the use of fuel that is used to transport your produce from half a world away. You also might want to consider buying your produce from local producers like at fruits and vegetable stands instead of buying the produce from your local grocery store chain.
If you have a fireplace, take advantage of it and use it in the winter for the heat in your home. If you don't have one then consider having a wood burning stove or pellet stove installed in your home. Either one of these types of heating devices are going to help you cut down on your energy use in a big way. Make sure though to avoid buying a used wood stove. It's best to go with new ones that you know will be more energy efficient.
Final Note: If you do have a fireplace, make sure that you have the chimney cleaned by a professional at least one time a year before you use it.
