“There is enough onshore-accessible wind for about 100 percent of our electricity requirements. In terms of our accessible resources, the biggest and most successful so far is wind.”
Ireland gets considerable wind, more than continental Europe. So, wind turbines sited strategically across the country could provide massive amounts of power with gas as backup. Development continues on ways to store power so it can be used when the wind isn’t blowing, such as batteries and hydro (use excess energy to pump water uphill, then create energy in non-peak hours by having it flow back down, powering turbines.)
