FOR SAVE WORLD
Fossil fuels are the largest source of environmental pollution in the world. According to the sources, this type of fuel, going towards new and cleaner energy generation, priority will be present. Hydrogen is the most abundant element in nature, has the potential to replace fossil fuels.
NATURE, MOST POWERFUL FORCE
Use now energy from the sun and wind, Alternative is the only solution
What is energy?
Whatever is happening around us, the energy comes from. Look out the window. During the day the sun provides light and heat energy. During the night the street lamps use electricity to light the way for us. When a car is to move people or load, its power of gasoline (or diesel) is that there is one type of energy.Energy is the ability to do work. You can find various forms of energy: chemical energy, electrical energy, heat, light(radiant energy), mechanical energy, and nuclear energy.Stored energy and the energy of the moving Energy causes all changes to be made and it can be divided into two types:
* The energy stored "potential energy" is called.
* Energy in motion "kinetic energy
The experiments with a pencil do to better understand the differences between the two types of energy. Put the pencil on the edge of a table or bench. It has the potential pencil. Now push the pencil to fall. Pencil kinetic energy is falling. Now take the pencil off the floor and put it back on the table. You have to take your energy and boost your pencil. Lifting the pencil from the surface, it adds energy. That is why when the pencil is on the table, is called potential energy. The pencil has a height greater than the Earth's surface, the more energy that can be stored and greater distance to fall. This means it has more potential energy.One of the primary ways of measuring energy which is abbreviated as Btu British thermal unit (British Thermal Unit) is. It is clear that this unit has been used in Atglstan.Btu is roughly equivalent to the energy that can make a kitchen match.Thousand Btu of energy equivalent to a coarse approximation of the average chocolate bar or 4/5 of a piece of toast with butter. Making a pot of tea, some energy is Btu 2000.Energy can also be a single "J" is measured. British thermal unit is equivalent to one joule per thousand.
So to make a pot of tea, nearly 2 million joules needed.The word "joule" for an English scientist named "James J" was selected. Jules James lived from 1818 to 1889 and one of her discoveries is that heat is a form of energy.One joule is the energy equivalent to the mass of a pound to a height of 9 inches of lift.This means that if you take a package three kilos of rice half feet high, about 15 joules of energy will be consumed.Usually, scientists around the world, energy is measured in joules (or Btu). But instead of the metric system in the UK, (which are expressed in units of meters, kilograms, etc.) from English units (pounds, feet, Btu, etc.) are used. Like other metric units. For j can either use the prefix "kilo" use.
can be converted into a different form, such as stored energy converted from solar energy. But it can not be created or
destroyed. All the energy in nature, there are always different
form. Here are some other ways to get into the energy of the event:
When the lights are turned on, the energy stored in the batteries into
the light. Food is stored energy. Energy into chemical compounds that
have potential energy in food is stored. When your body's stored
energy is used to do work, potential energy comes in the form of
kinetic energy. If you eat too much of the energy stored in food is not
burnt but the extra energy is stored as potential energy in fat
cells. When you are talking on the phone, your voice is converted into
electrical energy which wire (or air) passes. The phone is on the
other side of the sound energy into electrical
energy to and from the phone plays.
