Agreed 100%, for energy and especially urban livability concerns.
For energy in particular, an even more effective stroke will be to finally begin scaling back our empire; the US military carbon footprint is an absolute shame.
Apartments for everyone, and no detached single family homes would be far more energy saving than basically all other energy saving measures combined. Well, I guess except for reducing the population itself.
You've described my hell.
> Well, I guess except for reducing the population itself.
Perhaps the population will decrease from the crime and depression of being crammed into a city where you can't see the stars at night, nor hear the wildlife by day, and there's no such thing as silence anymore.
In order of impact, reducing energy consumption/carbon emissions on individual level is
0) suicide 1) not having children 2) having a smaller earth surface area footprint 3) traveling less 4) buying less material things, including smaller vehicles in which to travel
At the end of the day, we can’t escape basic physics. Energy = mass * acceleration * distance. The less mass and the less distance you move the mass, the less energy you consume and hence less carbon emissions you produce.
