The main reason that renewable energy looks cheaper is that most countries chose, as a policy decision, to count the costs of dealing with its intermittent nature entirely against the non-renewables that have to fill in the gaps rather than the renewable generation. That's why Germany has wholesale electricity prices that regularly go negative thanks to green energy and some of the highest consumer electricity pricing on the planet - the renewables get the right to sell to the grid even when their power's not useful and the non-renewable have to pay for this, and then ultimately consumers have to pay when the non-renewables need to fill in for dips.
