How green is my supplierLast updated on 07/11/2019
Click Energy emerges as the greenest domestic supplier in Northern Ireland. Each megawatt hour of power it supplies has 115 kg of carbon content. Second is SSE Airtricity with a carbon content of 295kg
Suppliers have been able to offer less environmentally damaging power because of changes in the sources of energy used for generation
Fossil fuels such as coal and even gas are being used less and less as the electricity system accommodates more renewables.
The share of electricity consumption each type of fuel is responsible for across the island of Ireland is detailed in an annual report just out.
In the last ten years coal in the all island fuel mix has halved from 14% to just under 7%. Gas is down from just over 60% to just under 40%.
Meanwhile renewables have shot up from 14% to almost 50%.
The result is that our electricity is much less carbon intensive. A decade ago generating a megawatt hour of power created 500kg of carbon dioxide. That’s down to under 300 kg.
It has to be said that these are all island figures. The report doesn’t disclose the results for Northern Ireland separately.
