Grid stability and 100% renewables

New research from Stanford University professor Mark Jacobson seeks to remove any doubts about grid stability in a world powered entirely by renewable energy. The latest study models 100% wind water and solar powered grids across the United States, finding no risk of blackouts in any region and also broad benefits in cost reduction, job creation and land use.

Saturday read: China’s path to 100 GW

China is once again the focus of attention across the global solar PV industry. The country’s manufacturers have had a turbulent 2021, but domestic demand remains strong, particularly from the booming residential rooftop segment. Despite the supply challenges, China will likely reach 50 GW this year and possibly even 100 GW next year. Given the dynamic market and policy landscape, pv magazine publisher Eckhart K. Gouras recently caught up with long-time China solar expert Frank Haugwitz, the founder of the Asia Europe Clean Energy (Solar) Advisory (AECEA).

Renewables critical as NEM prepares for Step Change

Large-scale renewable energy generators, including wind and solar PV farms will ramp up to 140 GW from the current 15 GW, more than doubling every decade to 2050 while rooftop solar is expected to increase from 15 GW to 70 GW over the same period as the “accelerating” transformation of Australia’s energy sector continues.
