Re: alternative energy
Batteries are a rip off.
They will never pay for them selves.
If you can sell back to the grid, for a reasonable amount!, solar can be a worthwhile investment, If you live in a sunny area!
I have spent 10 years on solar and batteries, living in the rainforest. I have recently moved to where I now have mains power. I happily pay the bill!
No more generator back up, no more paying $150 every 3 months for gas hot water, no more $8k battery bank that has a 10 year life span, and as much power as I want any time I want.
