Thanks for this; we don't talk about this part of the solution nearly enough. We need such strategy to avoid ecological catastrophe.
In the early 1980s in college I studied Gandhi and Gandhian action and wrote a paper about using Satyagraha to further alternative energy and a more ecological society.
At the time the appropriate technology movement was in full swing, but while the tactics of the oppositional part of the movement seemed obvious, it was hard to come up with any way to compel anyone to build commercial wind turbines and solar PV, passive and active solar heating and cooling, etc. Home-made versions constructed by the "protestors" were the best I could think of—not the best solution on the scale we need it now. I've thought about that paper now and then and still don't know the answer.
There are several main parts to the solutions to climate catastrophe--replacing fossil fuels with efficiency, conservation and wiser, more ecological lives; reforesting the planet; transforming chemical industrial agriculture to local organic low-meat permaculture and transforming industry to benign, closed-loop, ecological forms. Some of those--tree planting and farm construction and conversion, etc.--can be done with voluntary action, and the fossil fuel industries might be convinced to shut down with blockades and actions like the Dharasana Salt Works, but compelling government and industry to cooperate to build clean safe renewable energy is less likely to say the least. Anything less than a full takeover of the government, compelling it to represent the people and nature (which must be given rights) rather than corporations and the rich, seems unlikely to get the scale of building we need. Suggestions would be appreciated.
PS I’ve always preferred ”peaceful” action to ”non-violent”; saying the word ”violent”, even with a ”non” in front of it, triggers the frame of violence, just the opposite of what we want.
