Planning ahead for Ireland’s electricity supply is by no means a simple matter, given the range of unprecedented issues that are coming to the fore.  Massive cuts in emissions must be achieved, whilst decisive action is required to ensure adequate supply of electricity at a time when usage is spiraling. Richard Douthwaite explains the balance that Ireland must achieve between efficient local generation and usage and ensuring optimal interconnection to global renewable electricity supply

Passive houses have long been considered the ultimate in low energy buildings. So when it comes to BERs, why don’t they always get a straight A? Lenny Antonelli investigates.

As Ireland struggles to meet its commitments to reducing CO2 emissions in accordance with the Kyoto Protocol, the renewable energy sector continues to flourish as wind farms rapidly develop and solar energy becomes increasingly viable

A typical Irish bungalow built in the early 1990s has been transformed with a green-tinted extension built in the spirit of modernism. Jason Walsh visited Enniskerry, County Wicklow to see how the old and the new were integrated

Kirk Shanks, Senior Researcher at the Sustainability Research Development Group, the Focas Institute, DIT describes the development of this new sustainable generation.

The announcement in 2007 of the introduction of Smart electricity metering led to widespread hope that Ireland could set a global example by empowering consumers to cut electricity use and generate their own renewable electricity. John Hearne investigates current progress on the initiative, and discovers signs that Ireland’s approach to smart metering could represent a missed opportunity.

No matter how energy efficient a building method is, constructing a house from scratch will always cause some damage to the environment - but what if a building material could absorb more carbon than it causes to be released over its life cycle? Lenny Antonelli visits a hempcrete house in Co. Down that seeks to trial this innovative method of building

A recent study undertaken by Dublin City Council could serve to shatter many commonly held misconceptions about how existing buildings can perform when compared to new build, even simply just in terms of running costs.

Local authorities upgraded hundreds of houses last year under a €20m government scheme, and the Department of Environment has doubled funding for 2010. With local energy agencies playing a key role on the ground, the programme offers vital lessons for keeping quality high in energy retrofit schemes. Words: Lenny Antonelli
