Batteries Cannot Make Renewables Reliable

This article was written by David Wojick and originally published by a Committee for a Construction Tomorrow (CFACT): 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 compared to what would actually be needed to make wind or solar reliable. The cost of battery based reliability would actually be stupendous, far more than we could ever afford. Here are some simple numbers...

How Well Do Electric Vehicles Perform in Our Extreme Weather?

The practicality of electric vehicles is an important issue, especially in a Northern climate. It is well known that cold temperatures impact battery performance, and batteries are the Achilles heel of electric vehicles. The Minneapolis Star Tribune explains some of the problems. Cold weather degrades the performance of electric vehicles, in part because energy must be diverted to warm the interior of the car. The Strip cites a AAA study that found that even relatively moderate cold (by Minnesota standards) has a severe effect on battery performance: A recent study by AAA found that electric vehicle owners can expect their driving range...

The Dirty Secret Behind “Clean Energy”

Renewable energy advocates often talk about wind and solar as "clean" energy resources, and talk about "dirty" fossil fuels, but how accurate is their assessment that renewables are actually clean? Not very. We've talked about the fact that wind solar, and batteries require massive amounts of copper, nickel, rare earth metals, lead, cadmium, and cobalt. Many times, these materials are mined in countries where there are few, if any, protections for the environment or workers. The Clear Energy Alliance has produced a very good video debunking the claims that fossil fuels are inherently dirty, and video shines a much-needed light on the...

Statewide View: Skyrocketing Electricity Prices Threaten Minnesota Mining

Renewable-energy advocates often cite increasing demand for steel, copper, nickel, and cobalt as a reason why Minnesotans on the Iron Range should support more renewable-energy mandates. There is no doubt that doubling the renewable-energy mandate would increase Minnesota's demand for these metals, but we won't be able to afford to mine them here....

Sunday Funnies: Wind and Solar Edition

Minnesota has spent well over $15 billion on wind, solar, transmission lines, and the profits utility companies make by putting these things in the ground, but we have no batteries capable of storing the electricity produced by wind turbines or solar panels and we're not likely to have them soon. Just 24 hours of battery storage in Minnesota would cost $133 billion, and that is not accounting for the loss in power experienced when it gets cold out, which tends to happen a lot here. In the end, we've blown billions of dollars building battery chargers when we have no batteries! ...

The Big Problem With Wind, Solar, and Batteries

The following article originally appeared in the Grand Junction Daily Sentinel. There have been many recent articles in The Daily Sentinel on Xcel's new Colorado Energy Plan related to climate change policy. In addition, the national news has been covering the Green New Deal being proposed by many politicians to wean ourselves off of fossil fuels in the next 10 years. It is ludicrous to think that we could live in a modern society without fossil fuels. Affordable fossil fuels such as coal, natural gas, and oil have brought more people out of poverty in the modern world than ever before. Nineteenth...
