The cheapest forms of electricity, measured in costs per kWh from project auctions (as in: country A wants plant of whatever form, various companies provide their bids and the cheapest offer, per kWh, wins) are solar and wind.

And regardless of what politians say, when something is a good investment, somebody does it. Hence the continious growth of solar, wind seems to run into way more hurdles, from regulation over NIMBY to technical issues.
