It reminds me candle sellers were against electricity because they would lose their jobs if the world adopted a better technology, what inevitably happened anyway and these people had to find alternative ways to work for a living. That is the normal as things are constantly evolving and something that is a necessity now won't be necessary anymore when we find a more efficient method to fulfill that same objective.
What shouldn't happen is to stop evolving because some people can't adapt themselves to changes in life.
People who act corporately are blind by their own selfish that they can't see the benefits they could also have by adopting green sources of energy.
Such protests may have a short term impact, but it won't block the inevitable. If something is ineffective compared to something else, then no matter how much the supporters protest, it can't be held afloat for too long. In the end, it is up to the consumers to decide whether he or she want to use it or not. The only option left here is to improve the efficacy or make it more affordable. Else, the alternative will gain acceptance. Now you can't force the people to use a commodity which is more expensive and unaffordable compared to the alternative.
