This document discusses different types of green energy, including bioenergy, solar energy, wind energy, and hydro water energy. It provides details on biomass, biofuels, solar heating and photovoltaics, horizontal-axis and vertical-axis wind turbines, and how hydroelectric power plants use dams or canals to harness the kinetic energy of flowing water. The conclusion emphasizes that developing renewable energy sources like solar, wind, and hydro is important to address concerns over greenhouse gases, pollution, and energy security, but fossil fuels will still be needed until cleaner technologies replace them fully.
Tidal power, sometimes called tidal energy, is a form of hydropower that exploits the rise and fall in sea levels due to the tides, or the movement of water caused by the tidal flow. Because the tidal forces are caused by interaction between the gravity of the Earth, Moon and Sun, tidal power is essentially inexhaustible and classified as a renewable energy source.
Tidal power can be classified into two types. Tidal stream systems make use of the kinetic energy from the moving water currents to power turbines, in a similar way to underwater wind turbines. This method is gaining in popularity because of the lower ecological impact compared to the second type of system, the barrage. Barrages make use of the potential energy from the difference in height (or head) between high and low tides, and their use is better established.

This document discusses electromagnetic induction and its key concepts. It describes Faraday's experiments which demonstrated that a changing magnetic flux induces an electromotive force (emf) in a circuit. Faraday's laws of induction state that an emf is induced whenever the magnetic flux through a circuit changes, and the magnitude of the induced emf is proportional to the rate of change of the magnetic flux. Lenz's law explains that the induced current will flow in a direction to oppose the change producing it.

2) Annual investment in the global energy transition must quadruple to USD 5 trillion on average to achieve the 1.5°C pathway.
3) Most progress has been in the power sector, but greater efforts are needed in sectors like transport and heating to accelerate the transition worldwide.
Oro551 res- unit 1 - extra terrestrial and terrestrial solar radiationkarthi keyan
This document is about solar radiation and renewable energy sources. It discusses the energy produced by the sun as solar energy, which is radiated as electromagnetic waves with wavelengths between 0.2 to 4 micrometers. The sun's energy reaching the top of the atmosphere consists of 8% ultraviolet radiation, 46% visible light, and 46% infrared radiation. It also discusses extraterrestrial solar radiation, which is the radiation incident on the outer atmosphere, having an average irradiance of 1367 W/m2. Terrestrial solar radiation reaching the earth's surface is always less than extraterrestrial due to atmospheric absorption and scattering. Direct, diffuse, and global solar radiation are also defined.

3. The document emphasizes that renewable energy is important because it provides environmental benefits, empowers future generations, and lessens dependence on fossil fuels.
Wind energy harnesses the kinetic energy of wind to generate electricity through wind turbines. Wind turbines convert the kinetic energy of the wind into mechanical power using propeller-like blades, which spin a shaft connected to a generator that produces electricity. The largest wind farms can have hundreds of turbines and generate terawatt-hours of electricity annually without carbon emissions. The leading countries for installed wind power capacity are China, United States, Germany, India and Spain.
The document discusses energy efficiency and conservation. It explains that efficiency means reducing energy losses during conversions from one form to another. Conservation refers to reducing consumption through lifestyle changes and technology. While the total energy in the universe remains constant, the form of energy can change through conversions. Common energy sources include fossil fuels, nuclear, and solar/wind, which are converted into more useful forms through devices. These conversions are never 100% efficient, with some energy always lost as low quality heat.
This document provides an overview of solar energy, including its history, development, technologies, applications, advantages and disadvantages.

There are several types of lightning including positive, cloud to cloud, cloud to ground, and ground to cloud. Positive lightning, also called a bolt from the blue, is less than 5% of strikes but six to ten times more powerful than negative lightning. Over 1990 to 2003, the average number of lightning deaths in the United States was 80 per year. The 30/30 lightning safety rule is that if the time between the flash and thunder is less than 30 seconds, wait at least 30 minutes after the last flash or sound of thunder before resuming activities. It is important to have a lightning safety plan and seek proper shelter inside a building, vehicle, or crouching low if outside away from trees or open areas.

11.calculation of electric field distribution at high voltage cable terminationsAlexander Decker
This document presents an analytical method for calculating the voltage distribution at high voltage cable terminations that use resistive materials like deionized water. The method models the cable termination as a coaxial cable end enclosed in a resistive medium. Equations are derived to relate the voltage, current, and electric field distributions as a function of position along the cable end based on the cable's capacitance and the resistivity of the termination material. The analytical solution provides insight into how different design parameters affect the voltage and stress distributions at cable terminations, which is important for controlling electrical stresses.
History of atomic structure pisay versionMika Gancayco
1. Ernest Rutherford conducted an experiment where he fired alpha particles at a thin gold foil and detected their scattering with a fluorescent screen.
2. Contrary to expectations, some alpha particles were scattered at high angles or even back in the direction of the source.
3. This unexpected result led Rutherford to conclude that atoms are mostly empty space, with a tiny, dense positively charged nucleus at their center that could deflect the alpha particles. This challenged the prevailing plum pudding model of the atom.

Lightning is an electrical discharge caused by imbalances between Storm clouds and the ground or within the clouds themselves. (Definition, Types, Causes, Distribution, Prediction)
https://www.cda.org.bd
The document summarizes lightning phenomenon and describes various types of lightning strikes and their effects. It discusses lightning protection methods for structures. Key points:
1. Lightning is a sudden discharge between clouds or between clouds and the ground. It can cause significant damage to structures and injury.
2. There are different types of ground lightning strikes depending on the direction of charge. The most common is negative cloud-to-ground lightning.
3. Effects of lightning include thermal, acoustic, luminous, electrodynamic, and indirect effects from surges. Protection methods aim to safely conduct lightning currents to ground.
The document discusses various topics related to lightning:
- Lightning is a natural electrical discharge between clouds or between clouds and the ground, accompanied by a bright flash and thunder. It originates from static electricity generated in thunderclouds.
- The average lightning bolt carries 30,000 amperes of current and transfers 500 mega joules of energy. Positive lightning carries significantly more charge and voltage.
- While harnessing lightning's energy is theoretically possible, no practical method has been found due to the unpredictability of strikes and difficulty guiding them.
The document discusses the process of lightning initiation and discharge. It explains that lightning occurs when positively and negatively charged regions in clouds or between clouds and the ground equalize. The document outlines the step-by-step process where water droplets accumulate in clouds, separating charges and creating an electric field. This electric field produces plasma that provides a path for the lightning bolt to discharge. Different types of lightning are also described such as intra-cloud, cloud-to-ground, and cloud-to-cloud lightning.
1) Lightning occurs more frequently during the inter-monsoon periods of March-April and October-November due to high temperatures, low winds, and high water vapor forming thunderstorm clouds.
2) In cumulonimbus clouds, positively charged regions form in the upper parts of clouds while negatively charged regions form in the lower parts. When the charge difference becomes too great, lightning occurs as a discharge between the regions.
3) There are three main types of lightning: cloud-to-cloud, cloud-to-air, and cloud-to-ground, with the latter posing the greatest risk to humans and structures on the ground.
The document defines and describes different types of overvoltages that can occur on power systems, including temporary, transient, lightning, and switching overvoltages. It explains that overvoltages are caused by both internal factors like switching and insulation failures, as well as external lightning strikes. The mechanism of lightning is then described in detail, including how charge separation in storm clouds leads to the formation of stepped leaders and streamers, completing an ionized conductive path between the cloud and earth.
Lightning strikes kill about 58 people in the U.S. each year, making it one of the top weather killers despite being underrated. Lightning results from a buildup of positive and negative charges within a thunderstorm cloud and between the cloud and ground. When the charge difference becomes large enough, a conductive path forms from the cloud to the ground through which current surges, creating a visible lightning flash. The safest place during a thunderstorm is inside a substantial structure without plumbing or electronics.
Lightning occurs during hot, wet storms when moist air rises to form cumulonimbus clouds. As ice crystals form in the clouds and fall as rain, static electricity builds from the friction between rising and falling air. When clouds become fully charged, lightning flashes occur as the electricity discharges in long bolts reaching several miles. Lightning flashes are extremely hot, averaging 34,000 degrees Centigrade, causing the surrounding air to expand with a loud blast of thunder. The text explains what lightning is, how it occurs within storm clouds, and its high average temperature.
This document provides a summary of different types of weather:
[1] Black ice forms on road surfaces and is dangerous as it causes many car accidents. Cities salt roads to prevent black ice formation.
[2] Tornadoes form from rotating thunderstorms when warm and cold air masses collide.
[3] Precipitation includes rain, sleet, snow and hail, and is part of the water cycle as water evaporates, condenses into clouds, and falls back to earth.
Lightning is a giant spark of electricity in the atmosphere between cl.pdfatexsalem
Lightning is a giant spark of electricity in the atmosphere between clouds, the air, or the ground.
In the early stages of development, air acts as an insulator between the positive and negative
charges in the cloud and between the cloud and the ground. When the opposite charges builds up
enough, this insulating capacity of the air breaks down and there is a rapid discharge of
electricity that we know as lightning. The flash of lightning temporatily equalizes the charged
regions in the atmosphere until the opposite charges build up again. Sun dogs fire on the horizon

electrical discharge that results from the rising and sinking air motions that occur in
thunderstorms. Lightning can be either connect from one aloud to another, or shoot from a cloud
down to the ground. Lighting also has different appearances and is always accompanied by
thunder. yypes of cloud-to-ground fightning include staccato, forked, ribbon, and bead ghtning -
Staccato lightning is a strike which is a short-duration stroke that often, but not always, appears
as a single very bright flash and often has considerable branching. - Forked lightning is a name,
not in formal usage, for cloud-to-ground lightning that exhibits branching of.

Lightning is a large-scale electrical discharge that occurs during thunderstorms. It is caused by the buildup of positive and negative charges within a thunderstorm. When the buildup becomes large enough, a lightning bolt occurs as the charges suddenly equalize. There are several types of lightning including sheet lightning, cloud-to-ground lightning, and heat lightning. Thunder is the sound caused by the rapid heating and expansion of the air along the lightning channel.
Lightning as an alternative fuel source an analysis of the viability to use l...Luis O Maymí
This paper analyzes the viability of using lightning as an alternative energy source. It discusses thunderstorm behavior based on satellite data, hypothesizes a lightning storage facility in Florida, and considers the economic feasibility. While lightning produces a large amount of energy, capturing a meaningful percentage on a global scale would require numerous large facilities around the world, which is impractical. Additionally, experiments show that attracting enough lightning via towers or rockets to power facilities is challenging. In summary, lightning produces substantial energy but harnessing it efficiently for energy production faces significant technical and economic hurdles.
Lightning is caused by the separation of positive and negative charges within thunderstorm clouds. As ice crystals collide within the clouds, electrons are transferred, leaving the top of the cloud positively charged and the bottom negatively charged. When the negative charge at the bottom of the cloud is attracted to the positive charge in the ground, a stepped leader forms to connect them. This stepped leader travels from the cloud to the ground in sections, with pauses in between. Once connected, a return stroke allows the flow of electrons from the cloud and positive charges from the ground, producing a visible lightning strike. The rapid heating and expansion of air during this process causes thunder.
Lightning is an atmospheric discharge of electricity that occurs when negative and positive particles inside storm clouds separate. It forms when the negatively charged bottom of clouds induces a positive charge on the ground, causing a spark to jump between them. Benjamin Franklin famously experimented with lightning by flying a kite during a storm and collecting a spark from the key attached to the kite string. Lightning can heat the air around it to temperatures hotter than the sun's surface and strike at speeds over 130,000 mph.
15. The Quran and The Modern Science ( Meterology) A Series of Presentation B...Mr.Allah Dad Khan
The document discusses scientific explanations for the formation of hail, thunder, lightning, and rain that are mentioned in verses from the Quran. It summarizes modern scientific understandings of how hail becomes electrified as it falls through clouds, causing lightning. Dark layers form inside rain clouds followed by electrical sparks (lightning) and loud noise (thunder). The Quran also notes that wind plays a role in fertilizing the clouds and causing rain to form, which science has since discovered to be true. The descriptions of natural phenomena in the Quran correspond to modern scientific understandings discovered long afterward.

Tropical cyclones form when sea surface temperatures exceed 26°C to a depth of 60m, particularly near the equator. While increasing temperatures are expected to worsen cyclone conditions over time, other factors like wind shear also influence cyclone formation, so their frequency may not rise consistently. Future cyclones could be more intense as oceans hold more energy, but not necessarily more common. Research is analyzing lightning and wind patterns within cyclones to better predict intensification.
The document analyzes cloud-to-ground lightning flashes recorded by the National Lightning Detection Network to determine if it can identify multiple ground contacts within single flashes. The researchers recorded video of lightning flashes and compared them to correlated stroke reports from the NLDN. They measured luminous characteristics and spatial separation of multiple ground contacts. The analysis found differences in electromagnetic fields between first and subsequent strokes. It also found the NLDN measurements agreed between all ground contacts observed in southern Arizona and Florida, demonstrating it can identify multiple contacts within flashes.

This document discusses the causes of lightning. It explains that Benjamin Franklin was one of the first to study lightning in the 18th century and proved his hypothesis that lightning is electrical in nature by attaching a key to a kite during a storm. The document then describes how water accumulates in clouds during the water cycle, causing collisions that separate charges and create positive and negative regions within clouds. This charge separation generates an electric field that rips electrons from air molecules, forming a plasma channel that allows lightning to discharge rapidly between the cloud regions and ground.
