I seem to see lots of marketing for smart meters suggesting that getting one is the answer to climate change, reducing energy use, and energy security. A smart meter does not change your usage for you though; you still have to decide to change/reduce your energy use. I feel as though the fraction of marketing for energy reduction is much less than for telling people that getting a smart meter is the solution.
It just feels like lots of "slow nudge" aimed at consumers which there isn't time for. It'd be far more effective to stop political blocking of various renewable energy generation projects and to proactively get people off gas. Also change the rules to stop the most expensive energy sources setting the prices?
And rather than have "Einstein" invoke patriotism just to get some automatic meters installed, use it to encourage a mass reduction in car use and a switch to public transport and/or active travel. Make it our collective aim to actually reduce our emissions, improve our air quality, our health, our neighbourhoods etc. And, yes, seriously fund public transport/active travel to make it work.
