Off-grid living: it’s time to take back the power from the energy companies [theguardian.com]
It’s official. Off-grid energy is moving from the eco-fringe to mainstream. Last month US investment bank Morgan Stanley announced that the off-grid era had arrived: falling prices for renewable energy equipment and rising prices for energy supplied by power companies are fundamentally altering the business model of the trillion-dollar electricity industry.
A key piece of the jigsaw came in another statement last month: Tesla Motors are now committing to a huge increase in battery production, bringing down the cost of energy storage capacity by over 50%. The power grid is like a giant battery and up to £500 per year of our energy bills is paying for the maintenance of that battery. Morgan Stanley calculates that Tesla’s batteries will only cost an off-grid household £350 per year, rendering the Utility company business model obsolete. “Our analysis suggests utility customers may be positioned to eliminate their use of the power grid,” says the Morgan Stanley report, Clean Tech, Utilities and Autos.
