Onshore wind is currently the cheapest source of energy for producing electricity, with a global average cost of $0.034 per kilowatt-hour (or $34 per megawatt-hour). Utility-scale solar comes in a close second at $0.043/kWh. Both are significantly cheaper than any fossil fuel or nuclear option for new power plants, and the gap continues to widen.

I'm unsure we can trust numbers that come from industry for they are always pulling the wool over our eyes to make their own technologies look better than others.
