Solar and wind power are wise. It is a good use of funds, and an achievable goal. We differ in only two areas, first I don't intend to connect to the grid at all, and I'm not concerned about CO² (since it isn't a control variable). Look at their 'model'; it is total feces, they haven't normalized their model for input variations, nor have they included the oceans in their thermal calculations. That said, I do love solar for the cost savings, and the independence it provides! You have made a good choice.
I'm half way to my goal of 24,000 watt hours for my homestead batteries, using salvaged laptop batteries. My system is 24 volts, and the cells will be current matched in assemblies of 8 banks of 7 LiIon cells in series. Each bank will have a TMOS power FET connecting to the common ground, that will allow the computer to shut down any problem bank individually. I have a power pole on the homestead, I just don't plan to use it.
If you really want to remove CO² from the atmosphere, use biochar (soaked in fertilizer tea) for your garden fertilization. It will provide amazing results, and the CO² will stay out of the atmosphere for a thousand years. The output of your garden (after the first year), will be at least half again more, and some see their produce double.
Stay blessed!
I don't buy into the climate thing that much, mostly because I think it's far too late to do anything about it, but I'm into saving money on power and my systems do that so it's all good.
Understand, I just hate bad (purchased) science! Interestingly, we are moving into a grand solar minimum, so cooling is inevitable. I'm planning for it....
I refuse to be grid tied because I don't think the grid will be reliable when the SHTF comes. I'm working on running a large generator on HHO gas with a custom gas generator design. If it's half as good as it is on paper, I may use it for heating too. So many options, it may run my truck too, using extra solar charging for the gas generator power source. But the generator's first....
Oddly enough, the solar panels actually collect heat as they generate electricity. They cause a local increase in temperature when they operate. I may collect this heat and use a peltier module bank, to make more electricity.
Keep on shooting my friend!
