By David Wojick, Ph.D. ~ Regular readers know I have been writing about the astronomical cost of energy storage required to make solar and wind (SAW) power reliable. I have published some simple engineering analyses showing that short term intermittency, a few cloudy or low wind days, requires a huge amount of storage. Now we […]

By Steve Goreham ~ Large-scale storage of electricity is the latest proposed solution to boost the deployment of renewables. Renewable energy advocates, businesses, and state governments plan to use batteries to store electricity to solve the problem of intermittent wind and solar output. But large-scale storage is only an insignificant part of the electrical power […]

By David Wojick, Ph.D. ~ Utilities are starting to experiment with adding batteries to wind and solar projects. These storage projects are feeding the mistaken belief that batteries can cure the intermittency that makes wind and solar unworkable as a reliable source of power. The reality is that these battery projects are trivial in size […]

By David Wojick, Ph.D. ~ The use of big batteries to partially offset the intermittency of renewables is growing rapidly. Unfortunately some utilities have adopted a deceptive practice with the public, making these battery packs seem much more important then they are. It is all part of hyping the utility’s supposed greenness, which helps their […]

By David Wojick, Ph.D. ~ The Colorado Energy Plan is a massive $2.5 billion scheme by Xcel Energy that substitutes wind and solar-plus-storage power for existing coal fired generation. The Plan is supposed to be based on a competitive procurement that received a multitude of bids. Only a few were selected and the makeup of […]

By David Wojick, Ph.D. ~ Press coverage of the crusade for 100% renewable electricity invariably talks about wind and solar energy. As I have pointed out, the wind and solar fantasy requires a stupendous amount of battery storage, which is never mentioned. This is because the 100% feasibility studies are deceptive. Wind and solar come […]

By Todd Royal ~ When understanding and examining energy storage for wide-scale, societal deployment that is scalable, affordable and reliable needs to include these factors: energy security, renewable power production and cyber security. At this time energy storage doesn’t meet any of these criteria. The best example is Tesla’s seemingly successful deployment November 2017 in […]
