It's official: Tesla is an energy company.

Shareholders voted in favor of Tesla buying SolarCity in a deal worth about $2 billion on Thursday. The core product being made by the "new Tesla" will be its solar roof product, first unveiled by Tesla CEO Elon Musk on Oct. 28.

Musk said the solar roof will be cheaper than a normal roof after the shareholder vote on Thursday.
