For several years, the State has prescribed that a certain volume of motor fuels (gasoline and motor diesel) be produced from renewable sources. That percentage has now risen to 8%. There are practical difficulties for motorists in having high levels of biofuels in our vehicles. These include the risk of vehicle breakdowns and disruption caused by such fuels blocking engine filters in cold weather and other damage to engines caused by high ethanol blends. Also there are significant concerns about security of supply of the required biofuel materials and consumers would face additional costs. Despite these negative consequences for motorists, the Irish state is considering raising the percentage of biofuels still further.
