Much hype exists in the media about green motoring. There is more of an agreement on the reality of climate change nowadays as people are becoming concerned at the changing weather patterns. A new multi million $ industry of Green living has sprung up from governments introducing new Green taxes to reduce emissions of CO2 to car companies releasing fuel sipping varients of their popular engines.
Bio fuels are hailed as the solution. Bio fuel is a fuel source which is grown instead of being drilled or extracted from our earths limited resources. Oils can be extracted from crops and made into a viable diesel alternative and Ethanol, a type of alcahol, as a substitute or additive for petrol based engines. Although this seems like a good solution we still demand huge amounts of fuel to power our modern lives. Questions are being raised about how much bio fuel can be produced without impacting on our farmers ability to provide essential food crops. The conversion and refining process also requires large amounts of energy.
Another solution involves the use of electric power to augment a conventional CO2 emitting engine. There are some very impressive implimentaions of this from the major manufacturers although questions again are being raised at the amount of CO2 generated in the production of these cars and particulalry the batteries which store the power and will only last for 100,000 miles or so. Once again we seem only to have a partial solution to the answer. Is is possible to combine the two approaches? We have yet to see a hybrid diesel engine but a petrol/ethanol mix with electrical supplimentation is a practical application. Is this enough to reverse the thread of major catastrophic climate change?
There are millions of cars around already and it will not be practical to convert these. We have to ask what causes the largest emissions of CO2 and take a view that the humble motorist emits little more than a minute portion of the total CO2 and then we need to make some serious lifestyle changes if we are really serious about reducing climate change. A consumer driven society with its throwaway and replace an item mentality needs to change. We also need to travel less and work from home. Growing our own food will further reduce our carbon footprint. So the answer to the problem is not to spend more money on "Green" technology we need quite simply to spend less money, evaluating our needs and denying our wants. This is perhaps not realistic, people adopt the "let others go first" mentality and we are left with a problem that is not being sorted and have big business corporations and governments around the world profiting from the "green" revolution.
