Renewable Energy

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

Government incentives are crucial to sparking a massive energy upgrade of our housing stock, but practical examples are just as important. Keen to push his home's energy performance to the limits, one Dublin homeowner overhauled his entire building fabric and installed renewable heating systems and heat recovery ventilation. Lenny Antonelli visited the house.

Nothing focuses the mind like a target. The growing impact of Building Energy Ratings (BER) is increasingly encouraging Irish people to aim for the highest energy rating they can. Patrick and Niamh Daly’s house in Mullingar takes this trend to the next level, using a myriad of sustainable green materials and technologies to become a net energy producer and go beyond the limit of the BER scale. John Hearne visited the nearly completed house to find out more.

The introduction of smart metering later this year presents a great opportunity to engage Irish people en masse into substantially reducing their energy consumption, simply by showing them how much electricity they’re consuming, and how much the cost varies at different times of the day. However, as Richard Douthwaite warns, there is a real risk that smart metering may come in a form that benefits the electricity companies and not the end-user.

As our recognition of the problems of dwindling fossil fuel supplies and climate change grows, the need to reduce the energy consumption and carbon emissions of our homes becomes increasingly apparent. Leading energy consultant Patrick Waterfield describes why and how we should switch to zero heating homes.

The need to reduce CO2 emissions and energy consumption from buildings has never been more immediate. There is a growing consensus that we must reduce our dependence on rapidly depleting, carbon intensive fossil fuels, which, amongst other things, will involve overhauling how buildings are designed, constructed and used.

Thermal mass can significantly influence a building’s space heating requirement – in some cases the effect is to increase it, and in others to reduce it. Leading energy consultant Ciaran King of Emerald Energy explains how this occurs, and by describing an assessment of the topic, provides some rules of thumb regarding when thermal mass may be beneficial, and when it may be detrimental.

RICHARD DOUTHWAITE proposes measures including energy upgrade of the housing stock  which could help to avoid economic meltdown, and JAY STUART outlines some energy saving measures which could be rolled out.

Richard Douthwaite reveals that oil and gas peak are barely mentioned in the Government's recent energy Green Paper.
