9. There ARE ways to store and deploy electricity. Your phone employs one such way.

Besides chemical batteries (and some of the nasty chemicals some use), mechanical batteries can be used too. Think of using a water pump while wind/sun is active to pump water up to a very tall water tower. When there’s no wind/sun, the water is allowed to naturally fall due to gravity and turn turbine impellers along the way which generates electricity.

This is an example that a physicist I used to work with gave me. As described, it won’t scale, but the idea is to divert a portion of electricity as it’s being actively generated and have it perform some mechanical work later that will generate electricity — acting as a mechanical battery.

Continuing to use fossil fuels is horrible for our environment and is constantly dwindling, making it more expensive the more you use it. But the OWNERS of fossil fuel sources will do anything to keep you handing over your money to them. They *might* even try to convince you that you need Liquified Natural Gas.

Another thing that can be done with wind/sun electricity while they are active is use that power to split H20 and recover the hydrogen to use later. Hydrogen production is another way to store energy.

We made a big deal about recycling our glass & plastic bottles instead of simply throwing them away. But that’s exactly what we do with fossil fuels.
