There are so many conflicting views and possible truths as to if and why the climate is changing and howmuch we are responsible for it, but as you say the more we use renewables the better,just in caseTo be honest, you don't even need to belive in climate change to see renewable energy is a good thing, and that personal investment in them will bring long term savings for your families. We have a mountain to climb to replace oil and gas and without more big breakthroughs we will need them for a long time yet, but renewables make them cheaper because we reduce demand for them, so it's win win, to move to renewable tech....where is the negative?
