Renewable energy is energy which is generated from natural sources i.e. wind, sun, rain etc.what is Renewable energy resources?, How does energy compare to other renewable energy sources? http://www.wesrch.com/
Energy generated by using wind, tides, solar, geothermal heat, and biomass including farm and animal waste is known as non-conventional energy. All these sources are renewable or inexhaustible and do not cause environmental pollution. More over they do not require heavy expenditure.
Natural resources that can be replaced and reused by nature are termed renewable. Natural resources that cannot be replaced are termed nonrenewable.
Renewable resources are replaced through natural processes at a rate that is equal to or greater than the rate at which they are used, and depletion is usually not a worry.
Nonrenewable resources are exhaustible and are extracted faster than the rate at which they formed. E.g. Fossil Fuels (coal, oil, natural gas).

Know about the Different Types of Renewable Energy.pdfSven Van Zanten
Renewable energy refers to energy sources that are replenished naturally and can be used indefinitely without depleting their resources. They are considered more sustainable and environmentally friendly compared to fossil fuels. Here are some of the main types of renewable energy:
Renewable energy and resources (MVGR).pptxAKHIL Battula
This presentation depicts, how renewable resources have an adverse effect on the environment. It begin with naming renewable energy resources and detail knowledge on their working. There after, slides explicit the side effects in production of renewable energy. To conclude, either the energy is source is renewable or non-renewable it always have an adverse effect on nature. So we need to develop our renewable energy resources more and more if we want to enjoy a peaceful and satisfactory life in today's energy hungry world.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. Renewable energy - any sustainable energy which
comes from natural resources such as sunlight, wind,
tides, rain, geothermal energy.
Some aspects of Renewable energy
It exists perpetually and is abundant.
Ready to be harnessed, inexhaustible.
Clean alternative to fossil fuels.
3. About 16% of global final energy
consumption comes from
renewables, with 10% coming from
traditional biomass (used for
heating) and 3.4%
from hydroelectricity.
New renewables (small hydro,
modern biomass, wind, solar,
geothermal, and bio-fuels)
accounted for another 3%
consumption and are growing very
rapidly.
The electrical generation globally
is mainly from hydroelectricity and
the rest from new renewables.

11. History
Humans have been using wind
power for at least 5,500 years
to propel sailboats and sailing
ships.
Windmills have been used for
irrigation pumping and for
milling grain
since the 7th
century AD
in Afghanistan,
India, Iran and
Pakistan.
12. Wind power is a renewable energy source used to generate electricity by
converting wind energy into mechanical energy. This mechanical energy is then
converted into electricity by the use of an electrical generator located within each
individual wind machine.
Blowing wind spins the blades of a wind
turbine – this device is called a wind
turbine and not a windmill
A windmill grinds or mills grains or is
used to pump water
Worldwide there are now many
thousands of wind turbines operating,
with a total nameplate capacity of
194,400 MW.
World wind generation capacity more
than quadrupled between 2000 and 2006,
doubling about every three years.
Off –shore wind turbine
13. Electricity generation
The blades of a turbine are attached to a
hub that is mounted on a turning shaft.
The shaft goes through a gear
transmission box where the turning
speed is increased.
The transmission box is attached to a
high speed shaft which turns a generator
that makes electricity
In a wind farm(which is a group of wind
turbines in the same location used for
production of electric power), individual
turbines are interconnected with a
medium voltage (often 34.5 kV), power
collection system and communications
network.

16. Solar energy is the
radiant light and heat from the sun.
It has been harnessed by humans
since ancient times using a range of
ever-evolving technologies.
Solar energy technologies include use of
solar energy for
solar heating
solar photovoltaic
solar thermal electricity
solar architecture
We can change the sunlight
directly into electricity by using
solar cells also called as photovoltaic
cells
17. How electricity is generated?
When sunlight strikes the solar cell
electrons are knocked out loose
from the molecule
They move towards the treated
front surface.
An electron imbalance is created
between both the surfaces of the
solar cell.
When the two surfaces are joined
by a connector like a wire , a current
of electricity occurs between the
negative and positive sides.
This electricity produced s used for
various purposes household and
industrially.
Use of many solar cells or setting a
solar plant provides the purpose.

Solar water heaters
20. Applications of solar technology :
Solar technologies are broadly
characterized as either passive
solar or active solar depending on
the way they capture, convert and
distribute solar energy.
Active solar techniques use
photovoltaic panels, pumps, and fans
to convert sunlight into useful
outputs.
Passive solar techniques include
selecting materials with favorable
thermal properties
designing spaces that naturally
circulate air
referencing the position of a
building to the Sun

22. Biomass (or Bio-fuels)
Biomass is all plant material, or
vegetation, either raw or processed,
wild or cultivated.
Bio-fuel is a type of fuel whose energy is
derived from biological carbon fixation.
Bio-fuels are derived
from biomass conversion, as well
as solid biomass, liquid fuels and
various biogases.
Uses - Industrial process heat and steam,
Electrical power generation,
Transportation fuels (ethanol and
biodiesel) and other products.
23. Socio-Economic Benefits
• Helps developing economies by promoting agrarian communities
• Increase in jobs
• Increase in trade balance (Indian perspective) due to lesser
dependence on foreign resources
Bio-refinery
A facility that integrates biomass conversion processes and
equipment to produce fuels, power, and chemicals from biomass.
Analogous to today's petroleum refineries
It is based on the “Sugar Platform” and the “Thermo chemical
Platform”

28. Geothermal Energy
History :
Hot Springs have been used for bathing at least since Paleolithic times
The oldest known spa is a stone pool on China’s Lisan mountain built in the Qin
dynasty in the 3rd century BC, at the same site where the Huaqing Chi palace was
later built.
Hot water springs form due to geothermal energy of the earth
29. Geothermal energy
it is thermal energy generated and stored in the Earth. Thermal energy is the energy
that determines the temperature of matter.
originates from the formation of the planet (20%) and from radioactive decay of
minerals (80%).
The Geothermal gradient, which is the difference in temperature between the core of
the planet and its surface, drives a continuous conduction of thermal energy in the form
of heat from the core to the surface.
Geothermal power is cost effective, reliable, sustainable, and environmentally
friendly, but has historically been limited to areas near tectonic plate boundaries.
Geothermal power has the potential to help mitigate global warming if widely
deployed in place of fossil fuels.
31. Generation of electricity using steam power plants
from geothermal energy
The steam rotates a turbine that activates a
generator, which produces electricity
There are three types of geothermal power
plants: dry steam, flash steam, and binary cycle.
Dry steam power plants draw from
underground resources of steam and is sent to
the turbines/generator unit to produce power
Flash steam power plants use geothermal
reservoirs of water with temperatures greater
than 360°F (182°C). This very hot water flows up
through wells in the ground under its own
pressure.
Binary cycle power plants operate on water at
lower temperatures of about 225°-360°F (107°-
182°C).
