Vayu has become the first Irish energy provider to supply electricity to customers entirely from renewable sources.
According to the latest Fuel Mix and C02 Emissions report, from industry watchdog the Commission for Energy Regulation, the Dublin- based firm is the only provider in the State to achieve a 100% renewable energy rating for its electricity supply.
The latest report shows that electricity supplied by Airtricity is based on a fuel mix of 50.5% renewable, with Electric Ireland, Energia and Bord Gáis showing renewable energy ratings of 24%, 20.9% and 15.1%, respectively.
Vayu managing director Colm Kennedy, said: "More and more Irish businesses are seeking access to renewable energy sources in order to reduce their carbon footprint and limit the environmental impact of their activities. This will continue to drive investment in renewable sources of electricity in Ireland over the next five to ten years and will have an enormous knock-on effect on energy production."
However, Mr Kennedy said much more needs to be done to increase the proportion of electricity sourced from renewable energy if Ireland is to meet Government targets of 40% renewable generation by 2020. He noted that while the amount of CO2 emissions for the industry, as a whole, has been on a downward trend, last year actually saw a slight increase in emissions. This corresponded to an increase in the sourcing of electricity from coal on the island of Ireland, standing at 20% in 2012 — up from 14% in 2011.
