This story and clip from CBS concerns an interesting municipal initiative from that hot bed of California radicalism, Berkeley.
Berkeley Solar Utility
Berkeley municipality voted last night to initiate a programme of municipal (subsidised?) loans to Berkeley residents to finance the installation of solar panels.
But, the Devil's in the detail, and the Berkeley municipality Executive has now got to come up with a fully worked through proposal.
But the principle of charging not the individual, but the property - collecting repayments through an "assessment" in the same way as property taxes - is a good one.
The questions that need to be addressed include:
- whether the claims of the solar panel salesmen stack up;
- quality control of both panels and installation;
- the requirement for smart metering;
- the relationship with the utilities who would buy the surplus energy;
- funding sources;
- tax issues.
As one or two ET'ers may know, my view is that there may be a better way of doing it than funding with a conventional loan.
This would be to create an "Energy Pool" whereby investors can buy "Energy units" in a Pool of future solar production, and conventional dollars are loaned interest free by the Pool to residential properties for installations of solar panels, or anything else that stacks up in terms of "energy payback" over time.
The resulting "Energy Loan" of x,000 KiloWatt/ Hours is then repaid via energy utility billing systems.
Investors receive no interest on these "Energy Units", but they are able to "hedge" against energy price rises, and they can either sell units or exchange them in due course for electricity.
The result is quite close to the increasingly popular "Exchange Traded Commodity" funds invested in energy, but with additional capabilities.
Indeed, it would open up the way for a new form of currency - an "Energy Dollar" or even a "Carbon Dollar" - consisting of a fixed unit of energy.
Kilowatt Cards show the possibilities for such an "Energy Currency", although that is a project by a charity which has yet to think through its enterprise model.
