The Tesla Powerwall Battery, the innovative new invention from Elon Musk, promises a further step towards grid-free living, but how much of a technological advancement is it and, more importantly, is it cost-effective?
The Tesla company launched the Powerwall Battery back in May of 2015 and describes the home battery as ‘Energy Storage for a Sustainable Home‘.
Powerwall is a home battery that charges using electricity generated from solar panels, or when utility rates are low, and powers your home in the evening. It also fortifies your home against power outages by providing a backup electricity supply. Automated, compact and simple to install, Powerwall offers independence from the utility grid and the security of an emergency backup.
The environmental benefits of being able to remove your home from the benefits of fossil fuels would make a huge impact on the world’s emissions, associated waste and, as a result, climate change.
In this video, Brent Rose of WIRED examines the financial viability of the Powerwall, and how its costs would break down for the average (US) citizen.
As it transpires, there would be quite a financial hit which would take some time to recoup, however, this is without taking one major factor into account and that it the possibility of establishing grants and subsidies which could act as an incentive to readjust the power systems within your home. If experiments were carried out in new builds, or even entire towns, it is inarguable that the environmental benefits would be immense.
