Letter in Cape Times 28th December 2015: "Year of the battery"

2016 will be the year of the battery, when Elon Musk uses his marketing and investment muscle to make battery usage widely used in home and commercial scale energy systems.

Embedded storage is just as important as embedded energy. Embedded means that the energy and storage is produced at the point of consumption, and it also means that if there is a fault at a large-scale nuclear or coal or hydro-electric or solar or wind power station, or on the electrical distribution network, that the embedded generators and storage can come into use.

Many parts of the US have realised how important embedded generation and storage is on their grids, especially in light of recent extreme weather events that they have been experiencing.

This makes our electrical grids much more resilient, increases security of supply and brings down the cost of production overall as our grids become more effective and efficient and because there is a lot less mismanagement of funds due to almost no possibility of corruption.

Our water grids already have embedded water in the form of peoples' pools and many 5 000 litre water tanks I see sprouting up in peoples' gardens and with pool covers and systems to make this water drinkable, the pools become much more effective and efficient at reducing the risk of drought and its associated effects.

Some pundits suggest that 30 percent of food is already grown in cities. This means that our food grids are becoming more resilient as well as the water and electricity grids, and therefore we should start seeing reductions in our cost of living over the next few years.

This cost of living is not only to ourselves, financially, but also to our planet, environmentally.

One should note that while Elon Musk has made the PowerWall well known world wide, it isn't the only battery that is available, although he is working hard to bring the price of lithium ion down.
