These companies provide many services from solar panel installation to emissions-free cooling. Here are some of those greentech and sustainable energy companies in Ireland

Energy Storage Ireland was established due to a clear gap in representation for companies active in energy storage. The group now represents about 70 member companies, covering developers, suppliers, consultants, and contractors involved in the energy storage supply chain. "Batteries complement renewable energy generation effectively," Smith says.
PCRE, which operates this solar farm in County Wexford, Ireland, supplies power through agreements with Microsoft and Google.

Wind and solar energy play a key role in Ireland’s transition from fossil-fuel-based electricity generation. But these precious resources will need to be stored for times when the wind doesn’t blow, or the sun doesn’t shine, says the ESB’s Clare Duffy
This integrated approach will also deliver security of supply by reducing Ireland’s dependence on fossil fuels from more volatile parts of the world and allow us to develop “home-grown” energy from our own natural resources.
Joint CEO and co-founder Justin Brown told pv magazine that despite Ireland’s challenging environment for solar, the company sees a lot of opportunity and is taking full advantage.
