I'd like a bigger emphasis on efficiency. Space heating/cooling in particular, your first big win is to increase efficiency before you even start to think about renewable. If you spend money to cool, increase ventilation, shade, find ways to reduce heat buildup in the first place. If you spend money to heat, insulate, wear more clothes, use public spaces more (share heat), shut doors. For both, use good thermostats or smart systems to manage heating and cooling.<p>In general you see a lot of advise for dealing with symptoms of our over consumption, not the cause. Buy less (toys, food, clothes, cars, travel, whatever). What you own, use it for longer, fix it, do without.
