RENEWABLE RESOURCES
SUBMITTED BY :ARYAVARTA GIRI

2. INTRODUCTION
WHAT WILL WE LEARN :-
1. RENEWABLE RESOURCES AND ITS TYPES.
2. NON RENEWABLE RESOURCES AND ITS TYPES.
3. CONSERVATION OF THESE RESOURCES
4. THANK YOU!! SLIDE.

3. WHAT ARE RESOURCES???
Resources: The total means available for economic and political
development, such as mineral wealth, labor force, and armaments.
Resources: The total means available to a company for increasing
production or profit, including plant, labor, and raw material; assets.

4. WHAT ARE RENEWABLE RESOURCES???
Renewable resources are natural resources that can be replenished in a
short period of time. Types of renewable resources are –
● Solar
● Wind
● Water
● Geothermal
● Biomass

5. SOLAR ENERGY
• Solar energy is energy that comes directly from the sun. The sun is a
constant natural source of heat and light, and its radiation can be
converted to electricity. Solar technologies :•Solar electric
•Solar water heating
•Solar space heating

6. ELECTRIAL SOLAR ENERGY
Energy from the sun can be directly converted to electricity using solar
cells, also known as photovoltaic's or PVs.
Advantage- pollution free
20-25 year warranty
used to offset utility power
stand-alone power for remote applications
Disadvantage - Costs 3-5 times more than utility power

7. WIND ENERGY
Natural conditions of climate and geography produce the winds
that blow across the landscape. Historically, windmills were used
to supply mechanical energy, for example to pump water or grind
grain. Modern day wind turbines produce electricity.

8. WIND ENERGY
ADVANTAGES:
Wind energy is friendly to the surrounding environment, as no fossil fuels are
burnt to generate electricity from wind energy.
Wind turbines take up less space than the average power station. Windmills
only have to occupy a few square meters for the base,

9. WIND ENERGY
this allows the land around the turbine to be used for many purposes, for
example agriculture.
Newer technologies are making the extraction of wind energy much more
efficient. The wind is free, and we are able to cash in on this free source of
energy.

10. WIND ENERGY
DISADVANTAGES :
The main disadvantage regarding wind power is down to the winds
unreliability factor. In many areas, the winds strength is too low to support
a wind turbine or wind farm.
Wind turbines generally produce allot less electricity than the average
fossil fuelled power station, requiring multiple wind turbines to be built in
order to make an impact.

11. Wind turbine construction can be very expensive and costly to surrounding
wildlife during the build process.
Protests and/or petitions usually confront any proposed wind farm
development. People feel the countryside should be left in tact for everyone to
enjoy it's beauty.

12. WATER ENERGY
Snowmelt and runoff from precipitation at higher elevations flow toward
sea level in streams and rivers. In an earlier era, water wheels used the
power of flowing water to turn grinding stones and to run mechanical
equipment. Modern hydro-turbines use water power to generate
hydroelectricity.

13. WATER ENERGY
ADVANTAGES:
Hydroelectricity is a renewable energy source that does not produce
greenhouse gases.
When a hydroelectricity water storage dam is built, the water in the dam
can be used as a source of drinking water and for recreational purposes
such as boating and fishing.

14. WATER ENERGY
Operation and maintenance costs for hydroelectricity plants are much
lower than for thermal electricity power plants. Breakdowns are few
because their mechanical design is relatively simple, and no excess heat is
generated during operations.
Hydroelectricity generating plants have a long life.

15. WATER ENERGY
DISADVANTAGES
Usually a large area of land has to be flooded to ensure a continuous flow
of water to the turbine. In some cases when a dam is built, large
populations have to be relocated. In China, the Three Gorges Dam Project
on the Yangtze River will displace more than 1 million people.

16. WATER ENERGY
DISADVANTAGES
Usually a large area of land has to be flooded to ensure a continuous flow
of water to the turbine. In some cases when a dam is built, large
populations have to be relocated. In China, the Three Gorges Dam Project
on the Yangtze River will displace more than 1 million people.

17. WATER ENERGY
Dams affect river ecosystems. Rivers usually experience seasonal flooding that
flush out river backwaters and deposit silt on riverbanks. Dams prevent those
seasonal floods and allow silt and vegetation to clog up river backwaters. This
causes changes to the environments, which may impact plant and animal
habitats. Hydroelectricity dams are costly to build.

18. WATER ENERGY
DISADVANTAGES
Usually a large area of land has to be flooded to ensure a continuous flow
of water to the turbine. In some cases when a dam is built, large
populations have to be relocated. In China, the Three Gorges Dam Project
on the Yangtze River will displace more than 1 million people.

19. GEOTHERMAL ENERGY
Heat from deep within the earth is called "geothermal energy."
Three types of power plants are used to generate power from geothermal
energy: dry steam, flash, and binary.

20. GEOTHERMAL ENERGY
ADVANTAGES:
The production of electricity from geothermal energy sources can be a
highly efficient means of delivering clean and renewable electricity to
many people.
Location is of key importance for the development of an efficient
geothermal power station and therefore, economically viable levels of
electricity can only be generated in certain areas of the world.

21. GEOTHERMAL ENERGY
There are only a handful of locations across the world that are capable of
producing viable and efficient levels of electricity from geothermal energy
sources and as a result of this, in 2007, less than 1% of the world's
electricity supply was produced from geothermal sources.

22. GEOTHERMAL ENERGY
DISADVANTAGES :
Although geothermal energy can be a useful and economically viable
renewable energy source, there are several disadvantages of using the
power of geothermal energy to provide hot water for your home.

23. GEOTHERMAL ENERGY
The initial cost of design and installation can be costly yet this investment
would be likely to pay off over the years of operation.
The area needed to lay the piping system can be quite large and this may
not be suitable for small developments.

24. BIOMASS ENERGY
Biomass is a renewable source of energy because the natural process of
photosynthesis constantly produces new organic matter in the growth of
trees and plants. Photosynthesis stores the sun´s energy in organic
matter. Biomass is used to make heat, electricity and liquid fuels.

25. WHAT ARE NON RENEWABLE
RESOURCES??
Non-renewable energy resource: an energy resource that is not
replaced or is replaced only very slowly by natural processes. Primary
examples of non-renewable energy resources are the fossil fuels-oil, natural gas, and coal.

26. WHAT ARE NON RENEWABLE
RESOURCES??
Fossil fuels are continually produced by the decay of plant and
animal matter, but the rate of their production is extremely
slow, very much slower than the rate at which we use them

27. WHAT ARE NON RENEWABLE
RESOURCES??
Any non-renewable energy resources that we use are not replaced in
a reasonable amount of time (our lifetime, our children's lifetime,...)
and are thus considered "used up", not available to us again.

28. TYPES OF NON RENEWABLE
RESOURCES??
•Petroleum
•Coal
•Natural Gas
•Nuclear Power

29. Petroleum
Petroleum is extracted and turned into a variety of fuel sources
including petrol or gasoline, diesel, propane, jet fuel, heating oil and
paraffin wax. Also known as crude oil, this fuel source is
nonrenewable.

31. COAL
Coal is also composed of organic matter --- matter that decomposed in
peat bogs, which then formed into carbon rock under immense pressure.
Coal is generally highly combustible and the world's most-used resource
for electrical generation. Burning coal releases massive amounts of carbon
dioxide into the atmosphere. In addition to being greenhouse gas
source, coal cannot be reproduced.

33. NATURAL GAS
Also a byproduct of decomposition, natural gas is mostly methane created as
organic matter decays. Once extracted, natural gas is processed to remove
everything but the methane. This produces a variety of other natural
gases, such as ethane, propane and butane, which are also used as fuels. While
it is a fairly clean-burning fossil fuel, it is a nonrenewable energy source because
it is a byproduct of thousands of years of decomposition within the earth's
crust.

35. NUCLEAR POWER
Nuclear energy may get mentioned in the same breath with renewable
power sources like wind and solar because it is clean-burning and
therefore more environmentally sound than oil or coal. But nuclear
energy is, in fact, a nonrenewable resource. The problem lies in the
element that enables nuclear power: uranium. The element uranium is
abundant, but only a certain type of uranium, U-235, is used to fuel
nuclear power. We have a limited natural supply.
