This worldwide acceleration in 2023 was driven mainly by year-on-year expansion in the People''s Republic of China''s (hereafter "China") booming market for solar PV (+116%) and wind (+66%). Renewable power capacity additions will
IRENA''s global renewable power generation costs study shows that the competitiveness of renewables continued to improve despite rising materials and equipment costs in 2022. For offshore wind, the cost of electricity of new

A 1.5 kW turbine would cost approximately £7,000 and deliver around 2,600 kW over a year depending on your location and wind speeds. A larger array that has a 15 kW capability would cost in the region of £70,000 and return approximately 36,000 kW of energy over a year. You can find a list of smaller wind turbine manufacturers (up to 100 kW) here.
The global weighted average levelised cost of electricity (LCOE) of new onshore wind projects added in 2021 fell by 15%, year‑on‑year, to USD 0.033/kWh, while that of new utility-scale solar PV fell by 13% year-on-year to USD 0.048/kWh and that of offshore wind declined 13% to USD 0.075/kWh.
The government’s advisory Climate Change Committee (CCC) has estimated that the cost of integrating variable wind and solar into the energy system is around £10/MWh when the generation mix is 50-65% renewable, with the figure rising to £25-30/MWh at 75-90% renewables.
For offshore wind, the cost of electricity of new projects increased by 2%, in comparison to 2021, rising from USD 0.079/kWh to USD 0.081/kWh in 2022.
Before you take the option of getting a roof mounted turbine you need to understand that it will probably not provide all the electricity you need (though it may well take the edge of increasing fuel bills over the next 20 years). The average cost of a roof mounted wind turbine is around £3,000-£4,000 which will also need to be maintained.
This was published under the 2022 to 2024 Sunak Conservative government The government has increased the maximum price for offshore wind projects in its flagship renewables scheme to further cement the UK as a world leader in clean energy.
