Good point ZenDog. I will write more on this in coming months, but I think community action against fossil fuels is a crucial part of the puzzle and the more the better - it creates higher costs for them and makes them less competitive. Of course tipping points are defined by the person calling them ! Fossil fuels are still expanding in many markets as you point out. But I think the tide has turned overall (for example huge collapse in forecast growth of coal use in developing countries) See here http://in.reuters.com/article/2014/03/20/energy-coal-prices-idINL6N0MH30Y20140320
Any decline in coal demand has got to be good news. A Chinese War On Pollution may be the single best thing to date in terms of positioning the geopolitical players in a way that makes a cooperative response to Global Warming even possible. But still, the U.S. consumes . . . or consumed . . . 18,490 barrels of oil per day during 2012 and our consumption beat China by nearly 2 to 1. Do you feel that the price of a gallon of gasoline at the pump is a fair barometer of demand? And if so, is demand a fair indicator of when or if a tipping point has been reached with regard to the demand for oil?
