Many influential people and organisations (scientists, politicians, WWF, UNFCC, celebrities and even the Pope, to name but a few) are advocating we move to renewable energy and keep 'fossil fuels in the ground'.
But the shift is slow.
What do you think will ultimately drive a more substantial move to clean energy? Policy or events?
(There is also a poll about this in the REI MOOC - Drivers for energy change.)
What needs to happen for us to meet the 25%+ decarbonisation level cited by the IEA?
One argument, that speaks for policy as the ultimate driver are its strategy for subsidies. Lowering (and ending) current fossil fuel subsidies would have a huge effect on the energy sector.
According to the article I am linking to, fossil fuel companies receive an estimated 5.3$tn per year as subsidies globally, shattering "the myth that fossil fuels are cheap by showing just how huge their real costs are".
In the article it is argued that phasing out fossil fuel subsidies, as pledged for by the G20 in 2009, would show the real costs of fossil fuels and thereby make subsidies for renewables (which currently are at 120$bn globally per year) redundant.
Any more arguments for any of the two given options?
