If you sometimes sit back in your chair and watch, with an element of incredulity, the violence that inevitably breaks out whenever climate related political summits occur, then you can see an element of the tension that is slowly but surely building up around the world. We are simply coming to terms with just how unsustainable our lives really are. Such anger and violence may be alien to most of us and we could wonder what drives these people to be so impassioned, but when we concentrate on some of the scientific evidence now available, we can see how our extravagant lifestyles and requirements are at odds with the planet. Most of us realise that we now need to aggressively cut down on our energy use, both individually and collectively, and to take a major element of responsibility for what we do. Greenhouse gases are building up in our atmosphere due to our use of those traditional fossil fuels – gas, coal and oil, raising our Earth’s temperature and threatening considerable harm to future generations unless we act quickly.
Politicians are slow as usual and we cannot understand why they are not acting more quickly. Recent and crucial talks in Copenhagen resulted in only moderate agreement and few, tangible results. Each one of us has to take action and we are aware, for example, that we need to cut back on our transportation needs. Public transportation is very underused and we tend to scoff at the idea of carpooling, riding a bicycle, or even walking! Most of us are not sufficiently aware of environmental reasons to cut back on energy use, even though we recently saw just how volatile the supply chain can be during 2008, when gasoline prices went through the roof.
Our cars, trucks and buses are huge polluters of the environment and the automotive industry in the United States in particular is slow to shrug off the vestiges of an era when gas guzzlers were totally acceptable. It used to be okay to drive a car that was way too big, cumbersome and inefficient for our actual needs and as much as anything else, when gas was only 50 or 60 cents per gallon.
It seems that biodiesel fuel is a much brighter option for the future. It is derived from widely available agricultural sources. It is produced by mixing vegetable oil or leftover fats with methanol through separation. With a little bit of application and ingenuity, making biodiesel at home is a very viable solution. Generally, homemade biodiesel, as B100, can be used in your diesel engine vehicle with no modification, although a majority of vehicles these days operate on a blend of biodiesel and conventional petrol diesel (B20, B40 and so on).
Bio diesel may be yet to catch on in popular opinion, but as we look at ways to cut back, think about hybrid vehicles and ways to live our lives in more sustainable fashion, more and more emphasis will be put on renewable energy forms. When this special fuel does eventually become widely available to people all around the world, we will have a much better chance at slowing the incredible rate of global ecological change.
