On May 1st, tech guru Elon Musk debuted Tesla’s new answer for sustainable energy in hopes of helping the world end its addiction to fossil fuels. Cue Tesla’s solar powered batteries, the Powerwall & Powerpack. The products essentially store sunlight and convert it into clean energy. Elon states around two billion of the larger Powerpacks can transition all electricity generation in the world to renewable energy. WOW.

Both products are currently up for preorder, with the cheaper Powerwall available for $3,500.
