Wind power is the conversion of wind energy into useful forms like electricity or mechanical power. Humans have been using wind power for at least 5,500 years to propel boats and ships, and windmills have been used since the 7th century AD in central Asia and the Middle East for irrigation and milling grain. In the US, windmills helped expand farming and ranching by pumping water, and also supported the expansion of rail systems by pumping water for steam locomotives. Compared to traditional energy sources, wind power has a relatively minor environmental impact as it consumes no fuel and emits no pollution.
In this report the history of using wind energy has been discussed. The causes of wind flow and the power in wind has been illustrated. The wind turbines, its different types and their advantages disadvantages, its construction has been described in details. The offshore and onshore wind turbines were discussed here and the challenges of offshore wind turbines are described briefly. The present global status of wind energy have also been mentioned. And finally the wind energy potential and opportunities have been discussed.

Le parole "sociali" sul web: quale significato?palamon
Alcune parole ed espressioni dei social networks rischiano di diventare vuoti automatismi compulsivi o simulacri della partecipazione. Qualche spunto per rifletterci su ritrovando (o scoprendo per la prima volta) il vero significato di quelle parole ed espressioni. Possiamo cliccarle milioni di volte, ma non sono le parole a darci socialità, se non le trasformiamo in comportamenti e azioni consapevoli.

Renewable energy Sources, Efficiency, Uses and latest Research Zohaib HUSSAIN
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 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 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.

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. Wind power is the conversion of wind energy into a useful form of energy,
such as using wind turbines to make electricity, windmills for mechanical
power, windpumps for water pumping or drainage, or sails to propel ships.
The total amount of economically extractable power available from the wind is
considerably more than present human power use from all sources.
3. 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 what is now
Afghanistan, India, Iran and Pakistan.
In the US, the development of the "water-pumping windmill" was the major
factor in allowing the farming and ranching of vast areas otherwise devoid
of readily accessible water. Windpumps contributed to the expansion of rail
transport systems throughout the world, by pumping water from water wells
for the steam locomotives. The multi-bladed wind turbine atop a lattice
tower made of wood or steel was, for many years, a fixture of the
landscape throughout rural America. When fitted with generators and
battery banks, small wind machines provided electricity to isolated farms.
4. Compared to the environmental impact of traditional energy sources, the environmental
impact of wind power is relatively minor. Wind power consumes no fuel, and emits no air
pollution, unlike fossil fuel power sources. The energy consumed to manufacture and
transport the materials used to build a wind power plant is equal to the new energy
produced by the plant within a few months. While a wind farm may cover a large area of
land, many land uses such as agriculture are compatible, with only small areas of
turbine foundations and infrastructure made unavailable for use.
