Americans call the night of July 13, 1977 "Night of fear." Then there was a
huge in size and consequences of the accident at the power grids in New
York. Due to lightning and power line in 25 hours 9 million New Yorkers
turned out to be without electricity. Tragedy of the financial crisis was
accompanied by unusually hot weather and the unprecedented wave of
crime. After a power outage on the fashionable quarters of the city attacked
the gang from poor neighborhoods.
It was after those terrible events in New York, the term "blackout" has become a
commonly used in relation to accidents in the power industry.
Already in ancient times the fire was an
indispensable source of heat, light, human,
means for cooking, hunting tool.
Modern community is increasingly
dependent on electricity as well as heat.
Accidents on the electricity and heating
systems applied to tangible losses to
enterprises, governments and the public.
We can not imagine myself now without
technical equipment you use, whether it
is production, vehicles, information or life.
Since that time, the development of technical
ideas allowed to reach a new level of human life.

• A wind turbine is a device that converts kinetic energy
from the wind into electrical power.
• The smallest turbines are used for applications such as
battery charging for auxiliary power for boats or other
• Bigger wind turbines can be used to create large
amounts of electricity that can be sold to electrical
• Many countries are now creating wind farms to allow
less fossil fuels in the air.
The windmill above is located
at Holy Name High
School in Worcester Mass.
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
convert light into electric current
using the photovoltaic effect. The
PV industry is beginning to adopt
levelized cost of energy (LCOE)
as the unit of cost. For a 10 MW
plant in Phoenix, AZ, the LCOE is
estimated at $0.15 to 0.22/kWh in

I've always wondered, where there is electricity in our house?
Who is responsible for ensuring that the apartments, schools, hospitals was always warm?
It turned out that our city is the
main producer of electricity and heat -
I had the unique opportunity

Treatment - is the processing of water from
a natural source, to bring it into conformity
with the quality requirements of the process.
The engine room installed power boilers. They
produces steam for the turbines.
During the combustion of fuel in the water tubes,
arranged inside the boiler is heated to the boiling
point and is converted into steam.
The power boiler comprises of
the plurality of pipelines,
auxiliary devices and
Boiler drum. It resultant vapor is
separated from the water and
heated to the desired temperature.

Every year on the last Saturday in March, millions of
people around the world turning off the lights for an
hour. This action - a symbol of our respect for the
home planet, it is designed to draw attention to the
unsustainable use of natural resources and
Energy gives us light and heat. And more in the development of
mankind advances, the more energy it needs.
However, very often people do not think about what fuels that are
used for energy (gas, oil, coal) are irreplaceable natural resources, which
are slowly but surely come to an end.
Each of us needs to understand how important it is to conserve energy and use energy
saving simple rules in your home.

The most efficient way to use energy - just learn how to protect it.
