A decade ago, Elon Musk wrote a master plan for Tesla. Musk wrote in a recent blog post that the company has checked everything off that ten-year to-do list:

Create a low volume car, which would necessarily be expensive

Use that money to develop a medium volume car at a lower price

Use that money to create an affordable, high volume car And...

Provide solar power.

So Tesla needed a new to-do list to take it into the future. Again, it boils down to four concepts, which seems easy enough, but these are some complicated goals Musk is aiming for:

Bring together solar energy generation and storage. Tesla and SolarCity will combine to create a seamless personal utility company for customers. Create energy with solar panels and use it immediately to charge your Tesla vehicle or store it in your PowerWall for later household use.
