“Bumper month' for Scotland's renewables - New data published

4 November 2014

October 2014 was a “bumper month” for renewables in Scotland, new figures published by WWF Scotland today (Tuesday 4 November) reveal. [1]

Analysis by the environmental group of data [2] provided by the WeatherEnergy organisation found that for the month of October:

• Wind turbines alone generated an estimated 982,842MWh of electricity, enough to power 3,045,000 homes in the UK - equivalent to 126% of the electricity needs of every home in Scotland.

• For those homes fitted with solar PV panels, there was enough sunshine to meet an estimated 46% of the electricity needs of an average home in Edinburgh, 38% in Inverness, 37% in Glasgow, and 33% in Aberdeen.

• For those homes fitted with solar hot water panels, there was enough sunshine to meet an estimated 41% of the hot water needs of an average home in Edinburgh, 31% in Inverness, 30% in Glasgow, and 27% in Aberdeen.

WWF Scotland’s director Lang Banks said:

“While nuclear power plants were being forced to shut because of cracks, Scotland’s wind and sunshine were quietly and cleanly helping to keep the lights on in homes across the country. With wind power generating enough electricity to power 126% of the needs of every home in Scotland, it really was a bumper month for renewables in Scotland.

“Summer may be a distant memory, but for the tens of thousands of Scottish households that have installed solar panels to generate electricity or heat water, a third or more of their needs were met from the sun this October, helping reduce their reliance on coal, gas, or even oil.”

The figures come immediately after United Nations scientists published their latest report on global climate change, warning that without action the world faces “severe, pervasive and irreversible” damage. [3]

Banks added:

“The science is clear, if we are to prevent the worst impacts of global climate change, then the world needs to move away from fossil fuels. The good news is that here in Scotland we’re making good use of wind power to create clean electricity. However, if Scotland is going to meet its future climate change targets, then we need to see greater support for energy efficiency and renewable heat, as well as action to curb emissions from transport.”

Production (MWh)
Equivalent number of households potentially provided % of households
Scotland 982,842 3,045,000 126% (of Scottish households)
UK 2,496,842 7,736,000 28% (of UK households)

Solar PV

Production in kWh % of an average household electricity demand provided by PV
Aberdeen 107.3kWh 33%
Edinburgh 150.9 kWh 46%
Fort William 114.8 kWh 35%
Glasgow 121.6 kWh 37%
Inverness 124.8 kWh 38%
Pitlochry 99.6 kWh 30%
Stornoway 114.0 kWh 35%
Stranraer 127.7 kWh 39%
Wick 113.3 kWh 35%

Solar thermal

% of an average household hot water provided by solar thermal
Aberdeen 27%
Edinburgh 41%
Fort William 28%
Glasgow 30%
Inverness 31%
Pitlochry 18%
Stornoway 28%
Stranraer 32%

In generating the monthly report, the following assumptions are made:

▪ average solar PV installation - 3kW
▪ average annual household electricity consumption - 3,790 kWh
▪ average hot water (thermal) installation - 4.62m2
▪ average household daily hot water consumption - 122 litres
▪ number of homes in Scotland - 2.37million (based on 2011 census, released mid-2012)

For wind power, live wind energy output data is aggregated from nearly 8 GW of currently running wind farms in the UK, together with data from UKWED which shows the capacity of wind energy installed in each UK region. Government data is used to provide the capacity factor of wind energy in each region. All of this data is combined by WeatherEnergy’s EnergizAIR computer model to produce a realistic estimate of how much energy has been generated by the wind turbines in each region, it then converts this into how many homes could have been provided by energy from wind power.
