I sit and wonder how hypocritical it is for a Norwegian to drive an eco friendly Electric car to work at an oil exploration or drilling equipment company.
It is actually pure economics: Golf sized el'cars will start to become the ordinaire second family car or budget car if the tax break on purchase and road toll stations continues. Oil is not going to get any cheaper.
We are thankfully past peak oil: this means several things, firstly the issue above, it is likely not to get any cheaper particularily with the situation in Iran and the continuing OPEC dominance outside that for some time to come. This means that the market drives alternatives.
So over time a combination of market mechanism and emission total CO2 legislation makes the precious material more a supply for plastics and bitumen rather than fuel.
Reduction, recycling, replacement .
If global warming continues to be driven by India and China with the power resting in USA and Russia against the rest of the western world, then it won't be before the economic consequences of climate change hit home to the national budget and infrastructure of the national economies that these powers come to legislate much more than now.
So not until wall street is on a canal, the Shanghai docks are submerged and India starves half its population will the stream of greenhouse gases be tackled.
At the end of the day even after a nuclear war, mother nature will survive and recover by evolution. So we only try to protect the planet from a fate less serious than when photosynthetic plants spewed the then highly toxic oxygen by product out into the mostly CO2 atmosphere. It is human kind who will not survive their own folly.
