Nice idea, awesome job! I like the grove idea, will go nice with the OC grove masternodes or whatever we will call them.

I do have a few constructive critiques. Mostly punctuation. Forgive me.
Capitalize the first letter all of the main words like you started to do. (All, Energy, Efficient)
Need an additional comma before "and", otherwise all natural and energy efficient look like they are part of the same "idea" in the comma list, instead of being listed as things about OC. An opposite "for example": sex, drugs, rock and roll. -OR- sex, drugs, rock, and roll.  See how "rock and roll" gets separated as a full idea in the latter?
One thing about advertising, try not to have words with apostrophe's like "It's". Sometimes it's ok to add contractions depending on certain things, but delete the word in your mind, then reread it. Less is usually more. We already know the statement in the image is about OC, so this is a redundancy as well.

Other than that, I really like this.
