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

Question

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)?

Answer 1

Basically: Once the electricity is made, it’s sold at the market rate, when it’s inside the wires, it no longer matters what made it, just that it can power the kettle.

Only you, the customer, cares that it was made renewably.
