Elon Musk’s Tesla has launched Tesla Energy, a suite of batteries for homes, businesses and utilities, fostering a clean energy ecosystem and helping wean the world off fossil fuels.The company is already working with utilities and other renewable power partners around the world to deploy storage on the grid to improve resiliency and cleanliness of the grid as a whole.
The Tesla Powerwall is a rechargeable lithium-ion battery designed to store energy at a residential level for load shifting, backup power and self-consumption of solar power generation.
Powerwall consists of Tesla’s lithium-ion battery pack, liquid thermal control system and software that receives dispatch commands from a solar inverter. The unit mounts seamlessly on a wall and is integrated with the local grid to harness excess power and give customers the flexibility to draw energy from their own reserve.
The battery can provide a number of different beneﬁts to the customer including:
* Load shifting – the battery can provide ﬁnancial savings to its owner by charging during low rate periods when demand for electricity is lower and discharging during more expensive rate periods when electricity demand is higher;
* Increasing self-consumption of solar power generation – the battery can store surplus solar energy not used at the time it is generated and use that energy later when the sun is not shining; and
* Back-up power – assures power in the event of an outage.
Powerwall increases the capacity for a household’s solar consumption, while also offering backup functionality during grid outages.
The system is available in 10kWh, optimised for backup applications, or 7kWh optimised for daily use applications. Both can be connected with solar or grid and both can provide backup power. The 10kWh Powerwall is optimised to provide backup when the grid goes down, providing power for when the home needs it most. When paired with solar power, the 7kWh Powerwall can be used in daily cycling to extend the environmental and cost benefits of solar into the night when sunlight is unavailable.
The world currently consumes 20-trillion kWh of energy every year – which translates into enough energy to power a single family home for 1,8-billion years or supply energy to a nuclear power plant for 2 300 years.
Of all the fossil fuel consumed in the US, one-third is used in transportation and another third goes to electricity production. The US electric power sector alone produces over 2 000-million metric tons of CO2, which is equivalent to burning 225-billion gallons of gas. The EPA says it would require 1,6-billion acres of US forest to negate the environmental damage.
