Plan to 'change how electricity is produced and consumed' here
Electricity accounted for 19.3pc of Ireland's greenhouse gases in 2017.
There has been a shift towards renewable energy in recent years, with just over 30pc now coming from sources such as wind and solar.
Taoiseach Leo Varadkar said the plan will result in "reduced imports of fossil fuels and maybe even the possibility of Ireland becoming an electricity exporter".
"We are going to change how electricity is produced and consumed, how our homes and workplaces are heated," he said.
The target is to achieve 70pc renewable electricity by 2030. This will involve the phasing out of coal and peat-fired electricity generation plants. ESB's Moneypoint plant will close by 2025.
Bord na Móna will transition away from peat by 2028.
New planning guidelines for onshore wind are to be published this autumn.
And there is to be a big focus placed on microgeneration, with households expected to start selling electricity back to the grid by 2021.
Electricity/gas providers will also be required to give detail on energy use and potential savings to consumers as part of their bills.
