Huge amounts of resources have been spent on these technologies. What we have gotten back is not anything near the investments made to it. To many corrupted and compromised people involved in the science. The progs will use the improvements that should be mandated in A/C heating units, insulation, windows and doors, hot water tanks, etc. to make the inroads of green look better with the trillions of dollars of costs justified. You interfere too much. I once believed the crap also. Decades ago all of these homes were eventually going to have roofing shingles that were to be used also for energy intertwined. That was the deal breaker. They lied. Solar panels are different than shingles with the same ability to use the sun to create energy for the home. They lied. They lied. They lied. People got rich. On our backs as they usually do.That was the old solar panels. New ones are recyclable.
Try to keep up.
