The cheapest grid for the last two decades has been renewables for when the weather is optimal and fossil fuels when it is not. It is significant cheaper compared to renewables + storage or nuclear. A climate conferences doesn't really effects the conclusion unless governments start to add enough costs on the fossil fuel side so that one of the other solutions becomes economical viable, and clearly most countries are not willing to do that yet. Pledges doesn't mean anything.
