Energy is the amount of force or power when applied can move one object from one
position to another or Energy defines the capacity of a system to do work. Energy exists
in everybody whether they are human beings or animals or non living things for eg: Jet,
Light, Machines etc
Non-conventional or Renewable energy is energy which is generated from
natural sources i.e. sun, wind, rain, tides and can be generated again and again as andwhen required They are available in plenty and by far most the cleanest sources of
energy available on this planet. For eg: Energy that we receive from the sun can be used
to generate electricity.
Similarly, energy from wind, geothermal, biomass from plants, tides can be used
this form of energy to another form. The use of these sources have not only
resulted in their depletion. But also increased the population. Hence there is a great
need for improving technology in the use of non-conventional sources of energy which
could greatly decrease the environmental needs and which would assure the future
needs particles to rural people at affordable rates.
This paper presents an overview of waste to electrical energy technology The
basic concept and different features of WTEE is described. It includes the various
processes to produce Refused Desire Fuel (RDF), its characteristics and classifications.
This shows the solution to disposal of municipal and agricultural solid waste which is an
increasing problem today and the developments and goals are described.
Key words:Natural sources,WTEE,RDF,municipal and agricultural
Energy is the amount of force or power when applied can move one object from one
position to another or Energy defines the capacity of a system to do work. Energy exists in
everybody whether they are human beings or animals or non living things for eg: Jet, Light,
Machines etc..
Energy can have many forms: kinetic, potential, light, sound, gravitational, elastic,
electromagnetic or nuclear. According to the law of conservation of energy, any form of energy can be converted into another form and the total energy will remain the same. For eg:
a laborer when pushes the pile of bags, his potential energy stored inside him is converted
into the kinetic energy from the movement of matter or when you burn the wood it's chemical
energy is converted into the heat energy or when you charge your mobile phone the electrical
energy is converted into the chemical energy which gets stored inside the battery's molecules.
The many different natural and renewable energy technologies highlighted throughout the
website are by no means breakthrough. Many of the renewable energy technologies have
been around for years, and as time goes by, are increasing in efficiency.
Who uses Energy?
We human beings have been using vast proportions of earth's natural resources for our own
needs. We use energy for or heating and cooling, lighting, heating water and operating
appliances. Apart from that we use energy for many purposes, such as traveling in airplanes
and cars using oil that is converted into gasoline. The U.S. department of energy has divided
energy users into 3 category: Residential and Commercial, Industrial and Transportation.
Residential and commercial uses energy to light up their homes, for heating and cooling
purposes and to fulfill their daily basic needs. Industrial sector mainly consume energy for
lighting up of offices, running machines, for heating and cooling purposes. Transportation
sector uses energy for uploading and downloading of goods and services from one place toanother. Their mainly source of energy is oil on which transportation sector depends.
What are the sources of energy? energy are broadly classifies into two main groups:
• Non-renewable sources are cheap and easy to use. You can easily fill up your car tank
and power your motor vehicle.
• You can use small amount of nuclear energy to produce large amount of power.
• Non-renewable have little or no competition at all. For eg: if you are driving a batterydriven car your battery gets discharged then you won't be able to charge it in the
middle if the road rather it is easy to find a gas pumping station.
• They are considered as cheap when converting from one type of energy to another.
Cons
. Non-renewable sources release toxic gases in the air when burnt which are the major
cause for global warming.
• Non-renewable sources will expire some day and we have to us our endangeredresources to create more non-renewable sources of energy.
• The speed at which such resources are being utilized can have serious environmental
changes.
.
Why should we conserve energy?
Energy needs to be conserved to protect our environment from drastic changes, to save the
depleting resources for our future generations. The rate at which the energy is being produced
and consumed can damage our world in many ways. In other words, it helps us to save the
environment. We can reduce those impacts by consuming less energy. The cost of energy is
rising every year. It is important for us to realize how energy is useful to us and how can we
avoid it getting wasted.
To start saving energy is not a big thing at all. We can start saving the energy from our home
itself, just by turning off the lights during day hours, washing clothes in cold water or using
public transport instead of using our own vehicle and later can implement these things on
much wider scale at society level, then at city level then district level and finally at country
level. You might notice a small change in your monthly bills by implementing these changes
as they would be getting decreased more and more. With so many alternatives and so manytechniques about there, if millions of people like us start doing these things, it will help us to
save much more money and also help the environment.
With the above discussion we conclude that this WTEE technology is the better solution.
Being second largest population country the demand has drastically increased. And most of
our Indian villages still unelectrified. According to CPCB studies in India 70% of cities
won’t have sufficient facilities for transportation of MSW. By using this WTEE we can
avoid the MSW disposal problem and we can save a lot of money which is going to be
wasted for transporting to outer yards of cities and a lot of urban land which is wasted under
dump yards.
Not only in cities, this WTEE technology is also suitable for rural villages where Agricultural
and solid waste is abundant.
By preserving the Agricultural waste according to seasonal crops, we can light so manyvillages which are not aware of electricity. If we implement this technology in rural areas we
wont need to wait upto 2012 for “MISSION-2012 POWER FOR ALL”.
