Differences between renewable energies and non-renewable energies
Renewable energies are the energies that never run out, they don't pollute our planet and some of them produce a lot of energy. Non-renewable energies, are the energies that in a day they run out, and they pollute a lot our planet.

What is energy?
Energy is
the power that make things work.
We use energy
in everything that we do. We need energy to walk to school, to play, or
to cook our food. There are many different forms of energy , like : nuclear,
electrical, light, thermal, elastic, chemical, gravitational, kinetic and sound energy.
You can change energy from one
type to another, for example when you eat food you give your body chemical
energy, and you change this into kinetic energy when you move, heat energy to
keep your body warm and sound energy when you speak.
Energy can’t be created or
destroyed. Energy can be classified as renewable and non- renewable.

Why do we have to use renewable energies?
We have to use renewable energies because they're energies that don't expire and they don't make any pollution. We also save money using them and they sometimes produce more energy than non-renewable energies.

Biomass energy
Biomass is biological material from living, or recently living organisms, most often referring to plants or plant-derived materials. As a renewable energy source biomass can either be used directly, or indirectly—once or converted into another type of energy product such as biofuel.
Biomass is all biologically-produced matter based in carbon, hydrogen and oxygen. The estimated biomass production in the world is 146 billion tons a year, consisting of mostly wild plant growth.
