I, along with many other people, have fitted solar panels on my roof, installed a battery in my loft and replaced my gas boiler with a heat pump. Lots of people are bothered.
I believe the nobody can be bothered is a figure of speech, meaning: way too little.
Unluckily, your noble and exceptional on a global but even on a national scale efforts are not pulling that CO2 chart down.
I bet you had to fight the government or give away some of your produced energy to them to get it done.
