Due to the site and land use challenges posed by wind and solar power, attempting to meet our vast energy needs with renewable technologies alone would be prohibitively difficult.
C may be enough to see the end of hominids, us..I feel my own responsibility for the situation.

I have consumed, benefitted from cheap energy, travelled on business and for pleasure to far flung places.My lifetime carbon footprint will be in the top 25% of the world population despite my efforts now to minimise it.I have three children who are very aware and are taking decisions which will mean their impact on the world will be positive.. What should I do in this contrite state?

Should I wear a hair shirt, carry around my guilt, or go and live like a hermit?.The reality is that no matter how much I do personally, on my own, it will have a completely negligible effect on the problem.

UK carbon emissions are less than 1% of global emissions.
I am one of 66 million people in the UK.If so, a change in source hypothetically is a small change.
A biogenic source, meeting the specification, would require little or no change..If only life was so simple.
Current concerns about low level impurities exacerbated by issues like the discovery of nitrosamine impurities in medicines.2. , have led to a higher sensitivity to change and the risk of unknown threats.
