Israel’s 787-foot concentrated solar power tower—which will be the world’s tallest such tower once construction is complete—will bring up to 121 megawatts of renewable power to the country.

German architect André Broessel, of Rawlemon, has looked into his crystal ball and seen the future of renewable energy. In this case it’s a spherical sun-tracking solar energy-generating globe — essentially a giant glass marble on a robotic steel frame. But this marble is no toy. It concentrates both sunlight and moonlight up to 10,000 times — making its solar harvesting capabilities 35 percent more efficient than conventional dual-axis photovoltaic designs.

Statoil ASA, Norway’s biggest oil and gas producer, will invest as much as $200 million in renewable energy over four to seven years as part of Chief Executive Officer Eldar Saetre’s plan to diversify the company’s portfolio.

Australia’s first household to add a Tesla Powerwall battery can this week begin buying and selling energy on the electricity market, after the addition of a world-leading software program by Canberra company, Reposit Power.
