It's time our young go-getters help their communities run their own #StokvelMicroGrids !

#LCOE - we live and die by this simple yet overly-manipulated metric 😀 If LCOE did include all costs, then #RoofTopSolar would be king !
(Why ? because there is no "delivery" costs to get those rooftop green electrons to your door)

" The vast majority of rate increases comes from the dramatic overbuilding of Distribution grids. Most are built to old norms to meet peak demand for 50 hours a year. Using Virtual Power Plants, batteries, grid enhancing technologies are 90% cheaper " they say for the USA. And for RSA ?

Why should us 60million South Africans be the competition ? The Electrical Grid belongs to us, and we trust #ESKOM to run it fairly and properly on our behalf. -

The world is changing for sure, but we are all in this together, connected to the lifeline of our little national grid - and so we all need equal and fair access.

Paper always more comforting than an electronic copy - but when the publication is important for further research, the ability to quickly search the pages make an eBook the best bet.
eg - search for the key words "million hectares" and you get an immediate idea idea of where RSA is going 😀
