"it's too expensive to change to green"
My worry is not the cost of change. It is the usage of raw materials already bantered being worrisome, now being used in slightly different manufacture. Life of solar panels approximately 25 - 30 years degrading as aging in performance. End of life waste, toxins where are they going?
A field of solar cells. Making solar or photovoltaic cells requires potentially toxic heavy metals such as lead, mercury and cadmium. ... It even produces greenhouse gases, such as carbon dioxide, that contribute to global warming. Solar Panels
We need to approach many new technologies with caution, finding out more before taking the plunge, supporting something being sold by excellent salesman.
Having blockchain to move money is another scary yet exciting new concept, I am in total agreement change must come, highway robbers appear everywhere.
Another thought is 5g technology. Just last year a 36 meter mast was suggested across the road from where I live, after extensive research, many meetings with municipality, local community we managed to stop this. Fibre Optic has since been rolled out to go online mid-February. What is the difference both offer a new technology service, 5g has not been proved to be safe (don't believe WHO), lifespan is short, batteries problematic (stolen where we live) compared to fibre optic with line renewal every 20 years, is underground not creating an eyesore as these cellular towers every kilometer or so are.
No I don't wear a tin foil hat, nor do I take everything at face value, our generation and the ones before have left this world in enough of a mess not to be gullible to swallow everything dished up today!
