I use email and text largely as my "distributed memory". Countless times I have gone back to make sure of an agreement or a commitment that I may have otherwise gotten wrong. I also prefer them as being less intrusive to my time. A phone call demands immediate and undivided attention whereas the other are not.
Rapidly declining ESS costs with l-ion and flow batteries is expanding the capabilities of renewables even faster. It is generally seen that a combo of wind, solar and ESS will be increasingly the way forward for major power projects.
ESS is also economically eliminating gas peaker plants.
