Bridge over troubled waters




When you're weary
Feeling small
When tears are in your eyes
I will dry them all
I'm on your side
When times get rough
And friends just can't be found
Like a bridge over troubled water
I will lay me down
Like a bridge over troubled water
I will lay me down
When you're down and out
When you're on the street
When evening falls so hard
I will comfort you
I'll take your part
When darkness comes
And pain is all around
Like a bridge over troubled water
I will lay me down
Like a bridge over troubled water
I will lay me down
Sail on Silver Girl,
Sail on by
Your time has come to shine
All your dreams are on their way
See how they shine
If you need a friend
I'm sailing right behind
Like a bridge over troubled water
I will ease your mind
Like a bridge over troubled water
I will ease your mind

Nuclear Plant



Nuclear power is produced by controlled (i.e., non-explosive) nuclear reactions. Commercial and utility plants currently use nuclear fission reactions to heat water to produce steam, which is then used to generate electricity.

Nuclear power provides about 6% of the world's energy and 13–14% of the world's electricity,[1] with the U.S., France, and Japan together accounting for about 50% of nuclear generated electricity.[2] Also, more than 150 naval vessels using nuclear propulsion have been built.

Geothermal Power Plant



Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is energy that determines the temperature of matter. Earth's geothermal energy originates from the original formation of the planet, from radioactive decay of minerals, from volcanic activity, and from solar energy absorbed at the surface. The geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface.

* planet
* radioactive
* minerals
* volcanic
* activity

* continuous

Solar Power Plant



Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics converts light into electric current using the photoelectric effect.



Vocabulary:

- indirectly
- concentrated
- converts
- elctric
- photoelectric
- effect

Coal Power Plant


A fossil-fuel power station is a power station that burns fossil fuels such as coal, natural gas or petroleum (oil) to produce electricity. Central station fossil-fuel power plants are designed on a large scale for continuous operation. In many countries, such plants provide most of the electrical energy used.

Fossil fuel power stations (except for MHD generators) have some kind of rotating machinery to convert the heat energy of combustion into mechanical energy, which then operate an electrical generator

Wind Mill Farms


A wind farm is a group of wind turbines in the same location used for production of electric power. A large wind farm may consist of several hundred individual wind turbines, and cover an extended area of hundreds of square miles, but the land between the turbines may be used for agricultural or other purposes. A wind farm may also be located offshore.

Hydroelectric Dam


Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy

Japan Catastrophe


Northen Japan was devastated by a tsunami tht killed more than 10.000 people and destroyed all the infrastucture. A nightmare scenario in the nuclear plant of Fukushima threatens to pollute all the region with lethal radioactive isotopes
