Gas plant shutdowns caused California blackouts, not renewables (and wasting money on nuclear wouldnt help)

Last week started and ended with more unwelcome signs of climatic collapse, with the rough equivalent of a category 2 hurricane sweeping through Iowa starting the week, and California’s heatwave and wildfires creating a fire tornado to end it. By Climate Denier Roundup The intense heat in California, the hottest in 70 years, has strained its power grid, and over […]

China’s power sector could be 10% cheaper in 2030 with more renewable wind and solar energy

The costs for solar, wind and battery storage have dropped markedly since 2010 and are expected to decline further in the near future. This rapid fall in costs could have a large effect on energy system investment and policies, but has not been fully captured in energy modelling. This is particularly relevant for China, which is now debating […]

100% Renewable Energy: The emerging power of microgrids

Over many decades, the centralized power grid — a one-way flow of electricity, generated by large, remote power plants and distributed over miles of transmission lines to homes and businesses — succeeded in delivering electricity across continents to billions. But in recent years the system’s shortcomings have become increasingly evident. By Justin Gerdes Ensia The […]

In Australia, Hornsdale Battery for solar power backup has stabilized the grid and lowered costs

Engineering consultant Aurecon Group said in a statement last week the Hornsdale battery installed two years ago in South Austrialia has exceeded expectations for the way it has stabilized the grid and lowered grid related costs. So far, the Hornsdale facility has successfully met the challenge of three major system outages and reduced network costs […]

IRENA has a roadmap to 86% renewable energy by 2050 (through electrification)

The International Renewable Energy Agency (IRENA) published a new report this week which charts pathways to further accelerate a transformation of the global energy mix by intensifying electrification to the point that renewable energy can provide 86% of global power demand. By Joshua S Hill Cleantechnica The new IRENA report, Global Energy Transformation: A Roadmap to […]

Video: Accountability and ownership matter for the future grid in Puerto Rico

Shortly after Hurricane Maria struck the island of Puerto Rico, I penned a piece for Greentech Media exploring whether the residents could overcome a colonial past to build a greener grid. The Black Start conference in March 2019 convened on- and off-island energy experts to discuss whether this was still possible as the island’s governor insisted […]

New argument against wind and solar – they produce TOO much power (WSJ never heard of batteries)

The winds of change are a-blowin on climate, but don’t get too excited just yet. Sure, a certain Republican and coal-state Democrat paid lip service to the reality of climate change with an op-ed Dave Roberts described as “weak tea BS” (BS standing for “bipartisan solutions,” of course.) But here’s a quick test: does the piece about […]
