In the Orkney Islands of northern Scotland, three projects are aiming to prove economic viability of hydro power by capturing energy stored in surface waves and tides. The most recent to arrive this past summer was the Orbital O2, a massive device measuring in at 240 feet long and 650 tons. The concept is simple - anchor the body of the submarine-shaped machine, attach several massive rotors underwater, each of 65 feet in diameter, and let the tides do the work. The produced energy, rated at 2 megawatts, is enough to power 2,000 homes. In the coming months and years, this project will demonstrate its future potential. - AJ

The rise of clean electricity grids and electric vehicles has spurred growth in the mining of copper, a highly conductive and malleable metal. Mining copper poses environmental issues, especially for local residents. Mines can drain and contaminate underground water supplies, which creates serious health concerns for the local communities. Experts insist that copper is essential for the energy transition. Some proposed to provide incentives for recycling copper. In 2020, recycled copper met 35% of its global demand. Countries like China have already issued regulations for manufacturers to recycle copper. However, the heated problem between copper mines and local residents continues. -ZL
