Up until this week, the Powerwall was unchanged since the Powerwall 2 came out in 2016. The Powerwall is a Tesla Energy product that stores energy to be used at a later time. For example, if one loses power in a storm, the Powerwall would take over and power their house. The Powerwall is also useful for people who rely on solar energy during the day, as they can save their excess solar generated during the day to power their house at night. Recently, Tesla CEO Elon Musk announced that the capacity of every Powerwall 2 will be increased by 50% via an over the air software update. Tesla also made a significant change to how they sell Powerwalls. Previously, one could simply place an order for a Powerwall, but now, one can only buy a powerwall with Tesla solar.
On Wednesday April 21st, twelve US governors, including Andrew Cuomo issued a letter to President Biden requesting that all new cars and light-duty trucks sold in 2035 or later must be zero emission, and all new medium and heavy-duty vehicles are zero emission by 2045. This is a big step, but it will likely end up being more of a message than something that ends up a law. Many states have already taken action to pass similar legislation, such as Washington state and California, who have passed legislation requiring all new car sales to be zero emission vehicles by 2035.
