An
Energy Day or Week is an action
that aims to involve the wider public
in a wide range of activities related
to the production or use of renewable
energy sources and energy efficiency.
Energy
use intersects with all human lives:
All human beings use energy each
day.
from transportation to cooking,
heating or cooling rooms, industry,
lighting, water-use, to entertainment,
etc. Energy is more than mere numbers
on our utility bill,it means destruction
of nature every single time we use
it.
We Need Energy To Live We need to
stay warm. We need to get around.
We need illumination in our living
and work areas. We need to eat.
We need to drink. And we enjoy entertainment,
and communicating with others.
Energy is the main driver
of economic development. An insight
into the energy scenario provides
important clues to economic growth
and sustainability, apart from future
environmental concerns. In the context
of Gujarat, apart from its own energy
consumption, it also acts as entry
point for much of the crude oil
and petroleum products used in most
of the western and northern Indian
states.
Of this oil is less polluting and
natural gas is the cleanest, in
a gross sense. Electricity is clean
but its production might be polluting,
depending on the fuel and technology
used. However, power generated from
these sources is seldom continuous
and is therefore impossible to use
exclusively.
Where Does Energy Come From?
Energy comes from the sun. Energy
comes from the wind. Energy comes
from the waves. Energy comes from
burning things. Almost all energy
used by human beings throughout our
existence on planet Earth has come
from burning things. In modern society
we burn coal for most of our electricity
generation. Natural gas and oil-derived
products provide most of our other
energy needs. In Japan and France,
nuclear energy provides substantial
amounts of power. A small percentage
of energy comes from hydropower -
dammed rivers or elevated lakes with
water flowing through electricity-generating
turbines;now more viable than ever
and new
technology has improved their output
tremendously.Other forms of energy
include biomass (burning biological
material), and cogeneration (deriving
an energy production benefit as a
side-effect of energy use, such as
a gas-powered manufacturing plant
creating excess heat to power turbine
generators which put electricity back
on the grid).
Resources of Energy:
WIND:
Wind is
free, wind farms need no fuel.
Produces
no waste or greenhouse gases.
The land
beneath can usually still be used
for farming.
Wind farms
can be tourist attractions.
A good
method of supplying energy to remote
areas.
Wave:
The energy
is free - no fuel needed, no waste
produced
Not expensive
to operate and maintain.
Can produce
a great deal of energy
Solar Power :
Solar energy
is free - it needs no fuel and produces
no waste or pollution.
In sunny
countries, solar power can be used
where there is no easy way to get
electricity to a remote place.
Handy for
low-power uses such as solar powered
garden lights and battery chargers
Coal, Oil and Gas :
Very large
amounts of electricity can be generated
in one place using coal, fairly cheaply.
Transporting
oil and gas to the power stations
is easy.
Gas-fired
power stations are very efficient.
Nuclear power
Nuclear
power costs about the same as coal,
so it's not expensive to make.
Does not
produce smoke or carbon dioxide, so
it does not contribute to the greenhouse
effect.
Produces
huge amounts of energy from small
amounts of fuel.
