A switch to more environmentally friendly gasoline would allow the driver to motorize about 30 percent of the refueling costs.
Energy experts call on the government to accelerate the switch to gasoline with higher ethanol concentrations.
Energy experts say increasing the ethanol concentration of the fuel from the current 5% to 10% can have the same climate benefits as 100,000 electric vehicles.
The switch from E5 to E10 fuel is the goal of the government's 2030 climate action plan.
Today at the Bioenergy for Climate Action in Transport conference, they heard statements that a change can be made overnight and at no cost to you.
Economist Jim Power said the switch to electric cars will not happen quickly enough to reduce emissions in line with Ireland's goals, and fuel change is a way forward.
Power said: "Why is the government not prepared for a very quick transition from E5 to E10, why are they waiting until 2030, I just don't understand."
James Cogan from Ethanol Europe said fuel with higher ethanol concentration is equally effective but cheaper for drivers.
Cogan said: "There is no fossil coal in ethanol, so if we reduce the amount of fossil energy in our fuel tanks, we reduce the amount of carbon tax that we have to pay."
