eli5 – Why does renewable-generated electricity go up with the cost of non-renewable?

1.63K views

My UK energy provider says my electricity is produced with 100% renewables, so I presume water, wind, solar. So why am I affected by such big increases in electricity charges (price per kWh)?

My job relates to renewable / non-renewable energy production and electricity markets. I’m not based in the UK though, so YMMV.

The short answer is that you buy electricity from a grid. However, there is usually only one grid (not two separate grids for electricity produced from renewable and non-renewable sources). So, when the price of electricity from non-renewable sources goes up, the grid price also goes up.
