Environment
The
negative effect of human activities on environment is not only seen in India
but also in whole world. It results like ‘global temperature ‘or global
warming’. The reduction of energy sources and rising ratio of carbon in
environment has worried us all. Greenhouse
Gas (abbreviated GHG) is a gas in an atmosphere that absorbs and emits
radiation within the thermal infrared range. This process is the fundamental
cause of the greenhouse effect.
Carbon
dioxide (CO2)
Methane
(CH4)
Nitrous
oxide (NOx)
Ozone
(O3)
CFCs
(Chloro Fluro Carbon)
This concept is wrong that global warming is caused
only from operations of thermal plants, factories etc. The carbon emission is
also caused from Electrical Appliances,
like-
The
AC s and fridges are contributing more to carbon emission. An average
calculation is that Carbon emission from household appliances is 1190 kg Per
Annum per family. The
average household creates 10 Tonnes of CO2 per year in UK and 22 Tons of CO2 in
the US as a primary carbon footprint.
Reduction in carbon emission from
zero electricity hours-
Ø Load 3 MW = 3000KW, Power Cut Time:30 minute per
month
Ø Load in KWH =3000KWx0.5H = 1500 KWH
or Unit
Ø Carbon emission per month =
1500UX 0.69 Kg CO2 = 1035Kg CO2 emission saved
Carbon emission saving
ANNUALLY =1035 X12= 12420 KG =12.4 ton
(Ref: http://www.epa.gov/cleanenergy/energy-resources/refs.html), CO2 emission = 6.89 × 10-4
metric tons CO2 / kWh
Energy saving from zero electricity
hours-
Ø Load 3 MW = 3000KW, Power Cut Time:30 minute
Ø Load in KWH =3000KWx0.5H = 1500 KWH
or Unit
Ø Cost
of saving = 1500 x @Rs.7.00 = Rs.10500/-
It will be a great
contribution to energy conservation & sustainable development to environment.
Every unit of electricity or gas that we use results in carbon dioxide (CO2)
emissions to the atmosphere. If we reduce our electricity then we save money
and reduce the CO2 emissions and we should be responsible for that.
