At present, 80% of our world's energy is still coming from fossil fuels, which contributes significantly to climate change. The use of environmentally friendly energy is therefore the order of the day, but production around the clock is required. Corpower implemented a special power plant in Portugal that produces green electricity, even when the sun isn't shining or the wind isn't blowing. Its basis is the world's largest energy store, the ocean, with the energy of waves. Estimated potential on the Portuguese coasts for this purpose is about 34 gigawatts. Until now, however, the use of wave energy has met with major problems. For this reason, Corpower has developed a compound buoy in many years of trials, which absorbs the wave energy, is connected to the seabed and adapted to the respective conditions by means of an intelligent technology.
