Bottom line is, the fuel and energy market is continually becoming more fractured with a wider range of energy choices, as end-users seek to become substantially less dependent on one fuel type, primarily sourced from several unstable areas, largely run by groups who are intent on continually shafting those end-users with price-fixing/output restrictions.
I believe it's very important that attempts to produce alternative fuels at economic costs, are funded and encouraged.
Global Corporations unfortunately are not the best people to be funding these attempts, as they are always self-serving, and rarely in the best interests of the man in the street.
As for Global Warming/CO2 measurements, calculations and projections, I consider that any attempt to measure and project climate accurately is doomed to failure as the inputs into climate are so multiple and so varied - and the effects of those inputs are invariably pondered over, as to their individual strengths - that not even all the worlds scientists working 70 hrs a week with unlimited funding, would be able to measure all those inputs precisely.
At best, those inputs are "calculated", and that is where the GW/CO2 true believers are treading on swampy ground.
Finally, it is extreme scientific arrogance to be able to claim full knowledge about climate changes, merely by measuring (often with local inaccuracies) weather and climate conditions over a period of less than a lifetime, when climate has been in existence for billions of years.
This is the equivalent of trying to fully explain a nations air network and systems by microscopically examining one small stone in runway surfacing.
