GraphGist: Quick Look at Mainstream Renewables Energies

by Sergio Gijon

Introduction

Hey yo homies!

A common expression that is often used nowadays, since Al Gore’s book "An Inconvenient Truth", is renewables-energies. However, most people may ask themselves: lol, wat the hell is dat? watchu mean bro?

Urbandictionary.com defines the concept as "energy that is renewable" or "a ploy which government officials use to get elected, and which has no further useful practice, due to the fact of the immense cost and low effectiveness of the materials used". But the best way of summing up is, in my honest opinion, a little graph which provides a global quick look at mainstream renewable energies.

Names of mainstream renewables-energies

match (n:Energy) return distinct n.name as renewableEnergy;

It is a well-known fact that great majority of people only knows five kinds of renewable-energies or even less. Before continue reading this Gist, can you say more than five? Exactly, you can’t. Nobody!

What targets they chase?

As The Law of Conservation of Energy states, energy may neither be created nor destroyed but can change form! The next query show the most popular transformations.
