The document discusses various renewable energy sources including hydropower, tidal power, wind power, and biomass energy. It explains that hydropower harnesses the kinetic energy of moving water through dams and turbines, first being implemented at Niagara Falls in 1879. Wind power converts the kinetic energy of wind into electricity through wind turbines, and is currently the fastest growing energy source. Tidal power extracts energy from tidal currents and ranges. Biomass energy refers to organic matter from plants and animals that can be converted to energy through combustion. The document explores advantages such as renewability and economic benefits, and disadvantages including unreliability and high costs of some renewable resources.

1. Introduction
In today's world of climbing fuel prices, approaching the peak oil supply limit, and discussions of global warming, renewable energy is gaining more public attention and receiving more financial and legislative support. We need to learn more about the different types of renewable energy so that you can help educate your family, friends, and policymakers about ways to help our country move towards energy independence and environmental sustainability. According to a USAID report, Pakistan has the potential of producing 150,000 megawatts of wind energy, of which only the Sindh corridor can produce 40,000 megawatts.
2. Definition
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services.
3. Types of Renewable Energy
Most Countries currently relies heavily on coal, oil, and natural gas for its energy. Fossil fuels are non-renewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, renewable energy resources such as wind and solar energy are constantly replenished and will never run out.
Most renewable energy comes either directly or indirectly from the sun. Sunlight, or solar energy, can be used directly for heating and lighting homes and other buildings, for generating electricity, and for hot water heating, solar cooling, and a variety of commercial and industrial uses.
The sun's heat also drives the winds, whose energy, is captured with wind turbines. Then, the winds and the sun's heat cause water to evaporate. When this water vapor turns into rain or snow and flows downhill into rivers or streams, its energy can be captured using hydroelectric power. Along with the rain and snow, sunlight causes plants to grow. The organic matter that makes up those plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals. The use of biomass for any of these purposes is called bioenergy.
Hydrogen also can be found in many organic compounds, as well as water. It's the most abundant element on the Earth. But it doesn't occur naturally as a gas. It's always combined with other elements, such as with oxygen to make water. Once separated from another element, hydrogen can be burned as a fuel or converted into electricity.
Not all renewable energy resources come from the sun. Geothermal energy taps the Earth's internal heat for a variety of uses, including electric power production, and the heating and cooling of buildings. And the energy of the ocean's tides come from the gravitational pull of the moon and the sun upon the Earth.
In fact, ocean energy comes from a number of sources. In add

This report discusses the potential contribution that energy derived from the tides and waves can make to overall energy supply in a sustainable way. It covers the topics of wide range like how tides and waves are formed; functions of the possible and popular power generation systems especially tidal barrages,turbines, oscillating water columns and wave farms. Advantages and disadvantages of tidal and wave energy are also briefly discussed. Some cost data’s used give us brief insight into the economic prospects of the tidal and wave energy. By turning to potential along the Indian coastline, we found that India do have a huge potential of tidal and wave energy, though it has started very late. Government
initiatives and extensive research focused on the mentioned relevant opportunities will surely change the energy scenario.
NATURAL RESOURCES
Natural resources are material from the earth that is used to support life that meets people's needs. Any natural substance that humans use can be considered a natural resource.
Based on the availability there 2 types.
Renewable: resources that are available in infinite quality and can be used repeatedly. Ex; forest, wind, water, etc.
Non-renewable: a resource that is limited in abundance due to non-renewable nature and whose availability may run out in the future. Ex; fossil fuels ,minerals
Most efficient means of producing electric energy & do not create the air- pollution, the fuel falling water is not consumed. This favourable conditions to make hydroelectric projects attractive sources of electric power.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.

2. Hydropower
• Hydropower is electricity generated using the
energy of moving water. Rain or melted snow,
usually originating in hills and mountains,
create streams and rivers that eventually run
to the ocean.
• Ancient Greeks have used water wheels to
grind wheat into flour.
Image source: http://peakwater.org/wp-content/uploads/2010/11/hydropower1.jpg
3. Hydropower
• First hydroelectric power plant was built at
Niagara Falls in 1879.
• Hydroelectric power provides almost one-fifth
of the world's electricity.
• Hydropower is the cheapest way to generate
electricity today.
4. Types of Hydropower
1. Impoundment - An impoundment facility,
typically a large hydropower system, uses a
dam to store river water in a reservoir. The
water may be released either to meet
changing electricity needs or to maintain a
constant reservoir level.
5. Types of Hydropower
2. Diversion - sometimes called run-of-river, facility
channels a portion of a river through a canal or
penstock. It may not require the use of a dam.
3. Pumped Storage - When the demand for
electricity is low, a pumped storage facility
stores energy by pumping water from a lower
reservoir to an upper reservoir. During periods
of high electrical demand, the water is released
back to the lower reservoir to generate
electricity.
6. Tidal Power
• It is a form of hydropower that converts
energy of the tides into electricity or
other useful forms of matter.
• Tidal energy is therefore an entirely
predictable form of renewable energy,
which can be harnessed in two forms:

Site/iStock_000003310838XSmall.jpg
7. Tidal Range
• It is the vertical difference in height between
the high tide and the succeeding low tide.
• Artificial tidal barrages or lagoons may be
constructed to capture the tide.

8. Tidal Stream
• Tidal Stream is the flow of water as the tide
ebbs and floods, and manifests itself as tidal
current.
• Tidal Stream devices seek to extract energy
from this kinetic movement of water, much as
wind turbines extract energy from the
movement of air.

9. Wind power
• It is the process by which the wind is used to
generate electricity or mechanical power.
• Wind is the movement of air from an area of
high pressure to an area of low pressure.
• Farmers once used windmills to grind their
grains and pump water.
• Today, more and more people are using wind
turbines to wring electricity from the breeze.

future.com/Images/WindEnergy_Disadvantages.jpg
10. Wind powerWind power
• Wind energy production is growing rapidly
because construction of wind generators is
cheaper than building new fossil fuel-fired
power plants.
• Worldwide, wind is the fastest growing energy
source and many countries are rapidly
investing in new wind farms.
12. Kinds Of Wind Turbines
1. Vertical Axis Wind Turbines – turbines look
like a giant egg beater to harness wind
energy.
2. Horizontal Axis Wind Turbines – turbines look
like giant propellers of a plane. It is the most
commonly used turbines.
13. Biomass Energy
• The term "biomass" refers to organic matter that
has stored energy through the process of
photosynthesis.
• It exists in one form as plants and may be
transferred through the food chain to animals'
bodies and their wastes, all of which can be
converted for everyday human use through
processes such as combustion, which releases the
carbon dioxide stored in the plant material.
Image source: http://wastetoenergysystems.com/wp-

14. • Biomass has become one of the most
commonly used renewable sources of energy
in the last two decades, second only to
hydropower in the generation of electricity.

20. Summary: Renewables
What is he purpose of having these
renewable energy resources?
What do you think is the quickest and
the most effective way to decrease
energy consumption and to prolong
the availability of fossil fuels?
In fact, wind exists because the sun unevenly heats the surface of the Earth.
Renewable energy is, well, renewable: This means it has infinity of sustainability and we will never run out of it. Other sources of energy like coal, oil and gas are limited and will run out some day.
Environmental Benefits: It is clean and results in little to no greenhouse and net carbon emissions.
Reliable Energy Source: Our dependence on fossil fuels has increased considerably in last few decades.
Economic Benefits: Renewable energy is also cheaper and more economically sound than other sources of generated energy.
Stabilize Energy Prices: Switching to renewable energy sources also means steady pricing on energy.
Reliability of Supply: One shortcoming is that renewable energy relies heavily upon the weather for sources of supply: rain, wind, and sunshine. In the event of weather that doesn’t produce these kinds of climate conditions renewable energy sources lack the capacity to make energy.
Difficult to Generate in Large Quantity: Another disadvantage of renewable energy is that it is difficult to generate large amount of energy as those produced by coal powered plants.
Large Capital Cost: Initial investments are quite high in case of building renewable energy plants. These plants require upfront investments to build, have high maintenance expenses and require careful planning and implementation.
Large Tracts of Land Required: To meet up with the large quantities of electricity produced by fossil fuels, large amount of solar panels and wind farms need to be set up.
