Energy efficiency and energy saving are the most cost-effective means to meet the targets adopted in the EU climate change and energy package, i.e. a 20% reduction of greenhouse gas emissions (1990 levels) by 2020 and the non-binding target to achieve a 20% saving of the European Union’s energy consumption (compared to projected 2020 levels) by 2020.
Is iad éifeachtúlacht fhuinnimh agus spáráil fhuinnimh na modhanna is fearr ó thaobh costais de chun na spriocanna a chomhlíonadh a nglacadh leo i bpacáiste fuinneamh agus athrú aeráide an AE, .i. laghdú 20% d’astuithe gáis cheaptha teasa (leibhéil 1990) faoi 2020 agus an sprioc neamhcheangailte chun sábháil 20% de thomhaltas fhuinnimh an Aontais Eorpaigh a bhaint amach (i gcomparáid le leibhéil réamh-mheasta 2020) faoi 2020.
