Is green energy really cheaper?

We keep hearing in the media that green energy is becoming cheaper and cheaper as more wind turbines and solar panels are being installed - so shouldn’t our electricity prices become cheaper and cheaper?
Bulb is proud that they only supply renewable energy - so why are they reliant on general wholesale electricity prices which include non-renewables?
