But if you subscribe to an initial share offering you do own a share of the wind turbine(s) or whatever being built. I don't understand the difference there. No share price growth is expected or needed.
The only difference is that the electricity is sold to others, rather than given to you, but you get dividend income from that sale which, in principle you can use towards your own energy bills.
The ripple model just seems needlessly complex, and I'm sure will incur greater overheads which will eat into investors' income share.
I've been with Abundance now for 8yrs, and my portfolio of investments (I call it my Green Fund) has now grown to 28 different schemes. Some PV farms, some wind farms, hydro, bio-energy, house renovations etc. It's a great way to own a bit of RE generation, and I like to think that the money I've put into these helps offset my carbon emissions from other activities, purchases, and just living life.
Sadly, Abundance doesn't seem to have many new investments opening these days, and can be just for 2-5yrs, whereas I enjoyed investing in 10-17yr schemes / debentures. There is a 'Marketplace' where you can buy investments off other investors, but lately the mark up has gotten silly. I was buying say a 12yr PV scheme with a 5% annual return for around 105% of the value last year, but these days people are asking +20% (as an example).
But just to say there is 'stuff' out there.
