Some of the ideas that are popular with HN readers include:
1. Denser cities, like the centre of Paris or London rather than Los Angeles.
2. Walking, busses, metro systems, and cycle infrastructure for journeys within the city; high speed rail between cities.
3. Carbon taxes that cover the cost of recapturing the carbon. So ships and factories and things can keep operating, they've just got to plant some trees or whatever.
4. Nuclear power, alongside wind; solar; and a worldwide power grid to average out differences in production.
5. Remote working.
Ideas less popular with the HN community, but that you'll hear elsewhere include:
6. An end to endless growth.
7. Vegetarianism for everyone.
8. Total bans on certain polluting activities, where taxes would unfairly impact the poor and not the rich.
I'm sure you're aware of the political problems with all of these.
