Tax carbon and return the money to households as an equitable dividend.

There's already a group working on this and it's grown to over 200,000 in the last few years. Having more volunteers does help.

The Gini coefficient for carbon is higher than the Gini coefficient for income, so the cost of a carbon tax would be borne mostly by the rich, and the poor would mostly come out ahead with an equitable dividend.

That would surely help close the gap in rooftop solar faster than the status quo.
