One thing that does my head in is many countries are switching to optical fibre for internet/telephony which is leaving tons of redundant copper cable in the ground. In Australia at least I have seen massive lengths of 1000+ pair copper just cut and lying in the network because it's simply too hard to pull it out. If people/companies could just get their act together for the common good it would certainly help.
I also really tire of hearing people say "wind and solar don't guarantee supply", "we're putting DC in an AC network" etc. Yes, that's what batteries and inverters are for. If we stopped fucking around and built a battery bank for each town, with a backfeed supply from neighbouring towns in case of blackout, completely decentralising the system, we'd be a long way ahead.
Not that weird or hostile really, just a fair response to someone coming in and saying, "nah, this one" like an indecisive baby at a toy shop, with no reasoning or argument as to why their choice could be considered better.
