ASI report “Wind Power Reassessed” is featured in The Daily Mail and The Daily Telegraph

A new report, “Wind Power Reassessed: A review of the UK wind resource for electricity generation”, has been featured in The Daily Mail and The Daily Telegraph. The report, published jointly by the Adam Smith Institute and the Scientific Alliance, severely undermines the case for a move towards more wind generation in the UK because it suggests that wind can never be a major reliable source of energy for the UK. Specifically, the report found that wind farms generate below 20% of their supposed output for 29 weeks a year, and only exceed 90% of their rated output for 17 hours a year.

From The Daily Mail:

Wind farms will never be able to ensure the nation’s lights stay on because they are ‘expensive and deeply inefficient’, it is claimed today.

Confirming the long-held fears of many critics, a new study published by the right-leaning Adam Smith Institute and the Scientific Alliance argues the green energy revolution has been an expensive folly.

Researchers found that, on average, wind farms produce 80 per cent of their potential power output for less than one week annually – and they manage 90 per cent output for only 17 hours a year.

From The Daily Telegraph:

Wind farms can never be relied upon to keep the lights on in Britain because there are long periods each winter in which they produce barely any power, according to a new report by the Adam Smith Institute.

The huge variation in wind farms' power output means they cannot be counted on to produce energy when needed, and an equivalent amount of generation from traditional fossil fuel plants will be needed as back-up, the study finds.

Wind farm proponents often claim that the intermittent technology can be relied upon because the wind is always blowing somewhere in the UK.

But the report finds that a 10GW fleet of wind farms across the UK could “guarantee” to provide less than two per cent of its maximum output, because “long gaps in significant wind production occur in all seasons”.
