You have to understand, for this to happen you would need more than 15/20 amps of electrical use plugged into that circuit. As soon as a cloud reduces the solar output, the entire load would be on the utility end of the circuit and the breaker would trip.
This is what UL 3700 certification was developed to address.
You cannot single handedly solve climate change. Stop expecting that from yourself, do what you can, and accept that you are doing your part. Journey before destination my friend.
That’s pretty cool!
In my mind, local food is more about the economics of supporting small businesses in your community. Sure, eating beans and lentils shipped across the world to your closest whole foods may have a smaller carbon footprint, but your money is still being siphoned to the big businesses in that supply chain.
You mean the ones who were dumb enough to be the figureheads. The smart ones are the ones you don’t hear about in the news, but spend their money to put forward the dummy who perpetuates the systems that made them wealthy.
I consider the money I spent installing solar panels on my house an investment. My electric bill is less than $10 per month. If the stock market tanks, my electric bill will still be less than $10 per month. I helped support a local solar company and a solar manufacturer.
For investing, I use https://fossilfreefunds.org/ to help screen funds. Like you ate discovering, “ESG” is a broad term that gets slapped on a lot of things that may not fit your definition.
Sphere is one fund in particular that uses their voting power to try and steer the companies whose stock they hold away from fossil fuels.
If taste is your only concern a carbon filter like a Britta can do a lot. If hard water buildup clogs up the filters very quickly maybe consider a water softener (ion exchange or RO). With an RO softener you probably wouldn’t need the Britta filter.
You can also check your utility’s consumer confidence report (CCR). It will show the test results of water leaving the water plant. It won’t reflect lead levels at your home, which are impacted by your own piping. (It may include lead sampling at random locations around the distribution system.)
Collecting your own sample is perfectly fine. There are special instructions if you are specifically testing for lead that your utility should be able to provide to you. Contamination is really only a concern when testing for PFAS, but that test alone may cost more than your treatment system. Look at the PFAS data from your utility if you are concerned and realize you may be getting more exposure to PFAS from other sources than your water (Teflon cookware, food packaging, cosmetics, etc.).
In general, someone in the business of selling home treatment systems is has an incentive to tell you your water is poison and you absolutely need their system.
