Sustainable energy is the form of energy obtained from non-exhaustible resources, such that the provision of this form of energy serves the needs of the present without compromising the ability of future generations to meet their needs. Types of sustainable energy include the Wind energy, Solar energy ,Hydro power, Tidal power ,Geothermal energy ,Energy from bio mass.These energies have been used successfully in the agriculture in various applications. Therefore the sustainable energy usage in agriculture is a good alternative for the high demand of energy requirements.

2. • What is sustainable energy?
Sustainable energy is the form of energy obtained from
non-exhaustible resources, such that the provision of this
form of energy serves the needs of the present without
compromising the ability of future generations to meet
their needs.
• Types of sustainable energy
Wind energy
Solar energy
Hydro power
Tidal power
Geothermal energy
Energy from bio mass

3. • This systems can be very cost-effective and reliable for
many power needs on farms and ranches.
• Water pumping using wind turbine
Wind turbine electricity generation can be used to raise the
living standard of rural dwellers by improving agricultural
productivity.
After installing wind turbine water pumps in a farm, one
can raise higher value crops throughout the year and also
supply water to the livestock.
Other applications of wind power using water pumps are:
domestic water supply, water supply for livestock, drainage,
salt ponds, fish farms, etc.

4. • Electricity generation from wind turbine
• Through this the agricultural productivity is increased and
the cost on electricity bill is reduced.
• Grinding grains and legumes using windmills
• Wind energy can be used for grinding grains and legumes.

5. • Solar energy can supply and/or supplement many farm
energy requirements
• Crop and grain drying
Using the sun to dry crops and grain is one of the oldest and
most widely used applications of solar energy.
The different types of solar dyers include:
Natural open air dryers
Direct solar dryers
Indirect solar dryer
Solar hybrid dryer

6. • Solar cookers
This fall in to two categories as solar oven and direct
focusing solar concentrators
• Solar space and water heating
Solar space-heating systems can be used in livestock, dairy
and other agriculture operations that have significant
space and water heating requirements
• Greenhouse heating
Another agricultural application of solar energy is
greenhouse heating.
A solar green house has thermal mass to collect and store
solar heat energy, and insulation to retain this heat for
use during the night and on cloudy days.

7. • Solar water pumping in agriculture
Photovoltaic (PV) water pumping systems may be the most
cost-effective water pumping option in locations where
there is no existing power line.

8. • Remote electricity supply through solar photovoltaic
• It is a technology that converts light directly into
electricity. Photovoltaic material, most commonly utilizing
highly-purified silicon, converts sunlight directly into
electricity.
• They can power an electrical appliance directly, or store
solar energy in a battery.
• PV systems may be much cheaper than installing power
lines and step-down transformers in applications such as
electrical fencing, lighting, and water pumping.

9. • Hydro power electricity for farm appliances
Hydroelectricity contributes to the storage of drinking
water and also the Hydroelectric power plant reservoirs
collect rainwater, which can then be used for consumption
or for irrigation.
• Irrigation through hydro power

10. • Tidal power usage in aquaculture
• Irrigation in shrimp farming
• Tidal Electricity
• Grain Mills: Tidal Energy was used for the mechanical
crushing of grains in Grain Mills. The movement of Turbines
due to Tidal Energy was used in the crush Grains.

11. Biomass energy is produced from plants and organic
wastes—everything from crops, trees, and crop residues to
manure
• heating buildings, crop drying, dairy operations, and
industrial processes
• Generate energy on the farm: environmentally-friendly
alternative fuels that can substitute gasoline and diesel or
be blended with them to reduce toxic air emissions.
• produce steam and generate electricity: many electric
generators and businesses burn biomass by itself or with
other fuels in conventional power plants.

12. • Biodiesel : a low-polluting diesel alternative fuel made
from vegetable oils, animal fats, and even recycled cooking
greases.
• Ethanol: an alcohol-based fuel derived from crops, usually
corn, barley and wheat. Ethanol can be blended with
gasoline in varying concentrations
• Biomass gas for heating: The gas can then be burned to
produce heat, steam, or electricity.

13. • Heating Greenhouses with Geothermal Energy:
Geothermal energy has been used most extensively in
agriculture for greenhouse heating during the last 25 years
• Irrigation with warm water
• Open field Heating
• Production of algae Spirulina

14. • Geothermal aquaculture (fish growing):Breeding different
fishes in heated water enables their production all over the
year, and the use of geothermal energy makes it cheap and
profitable.
• Drying agricultural products: According to experience
already made, drying of agricultural products with
geothermal energy offers competitiveness and improves
quality for different products.

15. • Sea/brackish water greenhouses: A recently developed
process makes it possible to combine greenhouse heating
with the desalination of sea/brackish water using
geothermal energy
• Soil heating: Soil heating makes it possible to extend the
growing season and maintain a constant soil temperature
to increase yields.
• Milk pasteurization: Geothermal hot water can be used for
milk pasteurization and drying processes, while
geothermal steam can be used for milk evaporation and
the UHT process

16. • Sustainable energy is the form of energy obtained from
non-exhaustible resources, such that the provision of this
form of energy serves the needs of the present without
compromising the ability of future generations to meet
their needs.
• Types of sustainable energy include the Wind energy,
Solar energy ,Hydropower, Tidal power ,Geothermal energy
,Energy from bio mass.
• These energies have been used successfully in the
agriculture in various applications.
• Therefore the sustainable energy usage in agriculture is a
good alternative for the high demand of energy
requirements.
