3. INTRODUCTION
 Our society relies on energy to maintain our standard of living and to
underlie all other aspects of our economy.
 Currently, nearly all energy is generated in central power plants, which
use coal, oil, gas, water, or fissile nuclear material as the major fuel
source.
 The rising cost of traditional electrical energy, resource depletion as well
as environmental issues is the major concern
 The future development of producing technologies based on any of these
common fuels is fraught with difficulties.
 So, the electrical energy research and development be focused on so-
called nonconventional generation methods.

4. RENEWABLE ENERGY
Renewable energy is obtained from natural resources that refill in less than
human lifetime without diminishing the planet's resources.
→ Hydropower.
→ Geothermal.
→ Wind.
→ Solar.
→ Biogas
ADVANTAGES
→ Less global warming.
→ Improved public health.
→ Inexhaustible energy
→ Less Maintenance Cost.

WIND ENERGY
 Winds are created by the sun's uneven heating of the atmosphere,
abnormalities in the earth's surface, and the earth's rotation.
 The wind blows across the blades of wind turbine, spinning a shaft that
connects to a generator, which generates electricity.
SOLAR ENERGY
 Solar power is a type of pure green electricity that is generated from the
sun's light or heat.
 Electricity is generated by Solar panels using Sunlight
MAJOR DISADVANTAGES
 Renewable Energy is Unreliable
 Low-efficiency Levels
 Takes a Lot of Space to Install
 Not Always a Commercially-viable Option

6. LITERATURE SURVEY

1. Mr. Pradhan has carried out work on “Renewable Hybrid Power
Generation System for a Public Health Centre in a Rural Village”
The technological and financial viability of a solar PV–wind hybrid power
generating system with battery bank backup is thoroughly examined
It is found from the simulation results that the PV-wind hybrid system has
the lowest unit cost of energy as compared to independent solar photovoltaic
or wind energy system.
2. Mr. Ajay S. Tiwari “The research Study about Solar and Wind Hybrid
System for Rural Electrification”
Hybrid solar photovoltaic, Wind and battery-based energy system utilised
here is designed to address the challenges that arise with using conventional
energy sources.

FINAL MODEL

12. WIND TURBINE ARRANGEMENT
 The wind blows over the turbine blade, which rotates. The bigger gear
located on the turbine shaft spins with the spinning of the wind turbine. The
motor is rotated by the larger gear, which is linked to the smaller gear.
 Because of the gear arrangement, the motor has a higher speed than the
wind turbine. The motor will generate electric current as a result of this.

13. ENCLOSURE SYSTEM ARRANGEMENT
 The rain fills the water tub during the rainy season. Because the weight of
the water tub grows as it fills with water, it will drag the box and plate over
the wind turbine, completely enclosing it as shown in the final model.
 As a result, the turbine is protected from severe rain and the turbine blade's
lifespan is extended. Due to the presence of a small hole, the water tubs are
automatically drained after rain.
 The complete water tub mechanism can be replaced by a motor with a
sensor mechanism

15. SOLAR PANEL ARRANGEMENT
 Solar rays fall directly on the solar panel when it is angled. The energy from
the sun's rays is transformed into electricity.
ELECTRIC SYSTEM
 Electric current is generated by the motor. Because the motor's spin is not
continuous, the current produced is significantly variable.
 It can't be delivered to the battery directly. As a result, a voltage regulator is
utilized in the middle. It will assist in the production of consistent voltage.
 The voltage regulator's current is delivered to a tiny storage battery, which
stores the electricity generated.
 The solar panel also generates electric current, which is sent to the battery
for storage by a control system. 15

16. RESULTS AND OBSERVATIONS
16
 The total amount of electricity produced was adequate.
 When compared to wind, solar energy produced more energy.
Only smaller models can benefit from a wind blade protections ystem.
 In comparison to the electric output obtained, the cost of the finished
equipment is modest.
 The main issue observed was windblade showdow.
 Smaller-scale applications are better suited.
TYPE OF ENERGY POWER in Wh perday
Solar 60 Wh
Wind 60 Wh
Solar-Wind 120 Wh

17. Limitations
17
1. Energy is not continuous throughout the year.
The amount of energy produced may be enormous and continuous for
several months, but it cannot be obtained consistently throughout the year.
2. Difficult to lift the enclosure system.
Wind and solar energy are used to generate electricity. During the rain,
neither the wind nor the sun will be active. As a result, a very low output is
projected.
3. Low electric output during rainy season
The enclosure system requires light and strong material with high stiffness
or else the enclosure system can’t be lifted easily.
