Offshore wind power may be cheaper than new gas or nuclear generation.

According to Carbon Brief :

The UK government today awarded contracts worth £176m to 11 low-carbon electricity schemes, with offshore wind the big winner. These projects will generate nearly 3% of UK electricity demand.

Two offshore wind schemes won contracts at record-lows of £57.50 per megawatt hour (MWh). This puts them among the cheapest new sources of electricity generation in the UK, joining onshore wind and solar, with all three cheaper than new gas, according to government projections.
