Large-scale storage is only an insignificant part of the electrical power industry and doomed to remain so for decades to come. Intermittent wind and solar remain a foolish energy choice.
The minerals needed for the batteries for electric vehicles are often mined under horrific conditions, often by children.
Batteries are too expensive to back up intermittent wind and solar.
BY DAVID WOJICK, Ph.D. Some utilities have adopted a deceptive practice of making battery packs seem much more important then they are.
There are a number of studies that seem to say that 100% renewables is feasible without filling the world with batteries. How do they do that? It turns out that there are several common tricks.
The problem is batteries, which we never hear about when these grand plans are announced. Batteries are not included, even though they will be needed in impossible quantities. Here are the simple facts which dare not be mentioned.
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.
Hansen: “The notion that renewable energies and batteries alone will provide all needed energy is fantastical. It is also a grotesque idea, because of the staggering environmental pollution from mining and material disposal, if all energy was derived from renewables and batteries.”
Oil and natural gas aren’t just fuels. They supply building blocks for pharmaceuticals; plastics in vehicle bodies, athletic helmets, and numerous other products; and complex composites in solar panels and wind turbine blades and nacelles. The U.S. was importing 65% of its petroleum in 2005, creating serious national security concerns. But fracking helped cut imports to 40% and the U.S. now exports oil and gas. Today’s vital raw materials foundation also includes exotic minerals like gallium, germanium, rare-earth elements, and platinum-group metals. For the U.S., they are “critical” because they are required in thousands of applications; they become “strategic” when we don’t [...]
Where would Tesla be without subsidies?
Storing solar energy in batteries for nighttime use actually increases both energy consumption and carbon dioxide (CO2) emissions, the study found.
Batteries for electric cars can be very expensive, but according to the University of California Riverside there is a way to make electric car batteries more efficient.
