We are on the same boat my friend. Solar panel is still expensive to my country and if this project will become successful in the future, globally, we can all benefit from it specially if it is available to the masses.
That is right, we are not the only one who will be having a benefit from these project, but our environment also. We are having a good source of electricity, and we are also maintaining the beauty of our Mother Earth. I just hope that these project will be successful like other projects that Sir Yahoo handled.
Even when this campaign becomes successful, we definitely did not do anything to "preserve" the Earth's resources. Why? Because regardless if this campaign existed or not, there will still be people doing dynamite fishing, deforestation, illegal logging, or simply just polluting the whole country because of the huge factories that they have made.
SunContract was just made so we can buy energy online using the blockchain technology. What's up with all these solar panel thing? Obviously they are not going to ship you solar panels, and they surely are not going to make their own electricity grid all over the world. This project will probably just have partnerships on electric companies as mentioned in the OP.
So all your "save mother Earth" and "Solar panels are expensive" dramas are invalid. You will be paying the same amount of money, to the same people, but just with a different currency online.
