Debunking the Cheap Renewables Myth
We keep getting told that wind and solar renewables are cheap, yet our bills keep going up. So, what's going on?
By David Turver • 15 May 2024
Last week, I decided to write a Twitter/X post to summarise how much we are paying for renewables. It got far more traction than I anticipated, so I thought it would be helpful to convert it and extend it a little to make a bonus article on Substack that can act as a succinct response to all those who still insist on claiming renewables are cheap. In the UK, renewables are subsidised by three different schemes. Feed-in-Tariffs (FiTs) fund mostly solar power. The latest report for 2022-23 shows the scheme cost over £1.7bn and average total payment was ~£193/MWh, about 3X the current cost of gas-fired power at around £65/MWh (see Figure A).Figure A - Feed-in-Tariff (FiT) Generation and Total Payments (£ per MWh)Figure A - Feed-in-Tariff (FiT) Generation and Total Payments (£ per MWh)Contracts for Difference (CfDs) fund a range of technologies, but most of the subsidy goes to offshore wind. Latest data from the LCCC shows the subsidy per MWh fell dramatically during the energy crisis, but is now back at £95/MWh for offshore wind, £73/MWh onshore and £60/MWh for solar. April 2024 was a record month for overall subsidies with £268m paid out with average strike prices at £146/MWh for offshore wind, £113/MWh for onshore and £110/MWh for solar power (See Figure B).Figure B - Record Overall CfD Subsidies in April 2024Figure B - Record Overall CfD Subsidies in April 2024The CfD subsidy for burning trees in biomass plants rose from about £7/MWh in March to nearly £60/MWh in April. This encouraged more biomass generation and the total subsidy paid for biomass jumped from £2m in March to over £34m in April 2024. The total CfD subsidy paid for the last 12 months is over £2bn, and the trend is clearly upwards. By far the biggest subsidy scheme is Renewables Obligations Certificates, costing over £7bn per year. This scheme awards certificates for each MWh generated, a different number depending upon technology. April reference prices for intermittent renewables have been around £53/MWh, meaning the average price paid for offshore wind under the ROC scheme has been £176/MWh, onshore £118/MWh and solar £146/MWh including the value of the certificates (See Figure C).Figure C - Approximate Cost of ROC Funded Renewables 2024-25 (£ per MWh)
un tu tici visiem mēsliem tviterī, kam gribi ticēt.
Es - zinātnei un statistikai.
Bradypus rakstīja: Nu redz tu jau arī atzīsti, ka tici visiem mēsliem, kam gribi ticēt, ja vien kāds to ir nosaucis par "zinātni un statistiku". Zinātne un statistika ir izpratnes un skepticisma jādzieni, nevis ticības. Diemžēl "zinātnticība" ir jaunais proapagandas mašīnas rīks uz kuru esi pavilcies, kā jau ticīgam cilvēkam pienākas - tie ticīgie, kas tic ateismam, tic arī propagandai.
es ar tevi nerunāju, demagog
Pilnigi visu nevar pārbaudīt uz savas ādas - tam 8 mld mūžu nepietiks. kaut kas jau ir jāpieņem par gatavu, jeb "jātic", sauc to kā gribi
