Vehicular point.
A variation on the green theme is the enthusiasm with which the trendy people are embracing hybrid or electric vehicles, in particular the "Prius" as being wonderful for the environment.
A recent piece of research claimed that this was actually worse for the environment.
These types of vehicle use many exotic (for want of a better word) materials in its construction, particularly the electonics and battery. The carbon emissions and toxic waste or byproducts of manufacturing such a vehicle seemingly massively outweigh any gains by propelling it from A to B using hybrid or electric drive. Typically the vehicle is lugging round a large set of exotic batteries, with a limited lifecycle, which then have to be safely disposed of when the lifcycle expires. In addition while the hybrid unit still burns petrol, electricity used to charge a "pure" electric car comes from the supply grid which is majority supplied by fossil or nuclear, with a lower percentage of renewable e.g Hydro-electric.
Anyway, the research claimed that a Petrol engined V8 Jeep actually had a lower lifetime pollution cost than a Prius, as it was made of plain steel.
The simpler electronic car designs give other cause for worry as a TRL crash test on the G-WIZ electric car proved. http://www.dailymail.co.uk/pages/liv...n_page_id=1770
