Main sources of energy
This document discusses various sources of energy, including their advantages and disadvantages. It separates sources into fossil fuels, nuclear, and renewable types. Fossil fuels are inexpensive but will run out and pollute, while nuclear produces a large amount of energy without pollution but has risks of accidents and radioactive waste. Renewable sources like hydraulic, wind, solar, biomass, geothermal, solid urban waste, tidal, and wave energy have advantages of being clean and free but often have irregular production or high costs.
Energy
Energy is the ability to do work and cause change, and it exists in different forms. There are two main categories of energy: renewable sources that naturally replenish, like solar and wind, and non-renewable sources like fossil fuels that will run out. Fossil fuels are formed from decomposed plants and animals underground and include coal, oil, and natural gas. They are inexpensive but pollute and will become depleted. Nuclear energy is released from splitting atoms and provides a large amount of energy but risks accidents and radioactive waste. Renewable energies include solar, wind, hydropower, biomass, geothermal, tidal, wave, and solid waste energies, which have advantages like being clean or free but also

Hydrology
Hydroelectric power is a renewable source of energy that generates electricity from the kinetic energy of flowing water. Dams are constructed to trap water in reservoirs, allowing it to flow through tunnels and turn turbines that drive generators. The amount of power generated depends on the head, or vertical distance water falls, and water flow. While hydroelectric power has advantages of being renewable and producing no emissions, dams can negatively impact the environment by flooding habitat and disrupting river ecology.
Tides powerplant2 (3)
This document summarizes a presentation about tidal power. It discusses the different types of tidal power plants including tidal stream generators, tidal barrages, and tidal lagoons. Tidal stream generators use turbines placed in tidal streams, tidal barrages are dams constructed across estuaries with turbines installed, and tidal lagoons utilize artificial basins. Locations suitable for tidal power plants include areas with a large tidal range like narrow bay openings. Tidal power has advantages like predictability but also disadvantages like disrupting ocean creatures and altering ecosystems. While tidal power is proven, more research is still needed to maximize its potential as a renewable energy source.

Hydroelectric energy(2)
Hydroelectric energy is a renewable source of electricity that is produced from hydropower. It has several advantages including being a low-cost, flexible source of energy with no direct waste and lower greenhouse gas emissions than fossil fuels. However, there are also some disadvantages such as the potential for negative environmental consequences from damming rivers and flooding land, the high upfront cost to build hydroelectric plants, vulnerability to reductions during droughts, and the limited number of suitable locations remaining for new dams and reservoirs.
Tidal energy
Use of any given energy source in human society encounters limits to expansion. At the beginning of the 21st century some issues have achieved global dimension. Principal fossil energy sources, such as oil and natural gas are approaching exhaustion that may occur within the span of a generation
Closely linked to energy development are concerns about the environmental effects of fossil fuel energy use, such as global warming, and health issues due to air pollution. Energy development issues are part of the much debated sustainable development problem.

Tidal energy nd thermal pollution
This document discusses tidal energy and thermal pollution. It describes two types of tidal energy facilities - tidal barrages and tidal current turbines. Tidal barrages utilize potential energy from tidal differences using dam-like structures, while tidal current turbines capture kinetic energy from tidal currents using underwater turbines similar to wind turbines. Examples of existing tidal barrage facilities include ones in France and Canada. The document also discusses thermal pollution, which is the addition of excess heat to water bodies, and its impacts such as decreased dissolved oxygen levels and effects on aquatic life. Major sources of thermal pollution include power plants, industrial effluents, and sewage. Control methods include cooling ponds, cooling towers, and cogeneration.
Alternative energy
The document discusses problems caused by fossil fuels such as air and water pollution, health effects, and global warming from CO2 emissions. It proposes that alternative energy sources like nuclear, solar, hydroelectric, wave, tidal, wind, geothermal, and biomass could provide solutions because they cause minimal pollution, don't cause global warming, and are locally available renewable resources. These alternative energy sources are seen as increasingly important options as concerns rise over nuclear power and fossil fuel depletion.
Environmental impacts of hydroelectric power
Damming rivers can permanently alter river systems and wildlife habitats. A dam blocks fish migration, stops nutrients from flowing downstream, and changes water quality, all of which negatively impact the river ecosystem. The Iron Gates dams on the Danube River block important spawning sites and do not have fish passes, disrupting the migration and spawning of endangered sturgeon species.
Tidal Energy By Majida Islam
Tidal energy has potential prospects in Pakistan due to its tidal processes. Tidal energy exploits the movement of water caused by tidal currents and rise/fall of sea levels, which can power turbines. Pakistan has suitable sites like the Indus Delta creek system and Korangi/Sir Creeks, which see high tidal fluctuations of 2-5 meters that could produce 1100KW of power. Developing tidal energy plants could boost the socio-economics of coastal communities and help overcome Pakistan's energy shortage, though it cannot fulfill all demand and more research is needed to reduce costs.

Tidal energy
Tidal energy harnesses the kinetic energy of tidal currents and the potential energy of tidal height differences to generate electricity. It is a renewable and predictable source of energy. There are several methods of tidal energy generation including tidal stream generators, tidal barrages, and tidal lagoons. While tidal energy has advantages like being sustainable and producing no emissions, it also has disadvantages such as high initial costs, potential environmental impacts, and limited locations suitable for generation. Overall, tidal energy is a green energy source but still needs technological advancements to become more cost-effective and widely implemented.
Tidal power.
Tidal energy harnesses the power of ocean tides to generate electricity. It has advantages of being a renewable source that produces no greenhouse gases or waste once constructed. However, suitable tidal sites are limited and tidal power is only available for around 10 hours per day. The closest tidal power plant is the Annapolis Tidal Power Station in Nova Scotia. Tidal energy does not contribute to global warming as it releases no pollutants, but constructing large tidal plants can cost up to $48 billion. Tidal power costs a comparable 5-8 cents per kilowatt hour to generate as oil.
Wind Energy
Wind energy harnesses the power of wind to generate electricity through wind turbines. The uneven heating of the Earth's surface by the sun creates temperature differences and air pressure gradients that produce winds. Wind turbines convert the kinetic energy of the wind into electrical energy that can be used or stored. While wind energy has advantages like being clean and renewable, there are also disadvantages such as potential impacts on wildlife and noise produced by the turbine blades.
Tidal energy
Tidal Energy is one of the great resource of energy, Here in this presentation i tried to demonstrate as simple as possible.
Tidal energy
Tidal energy harnesses the potential energy of tides to generate electricity. Tides are caused by the gravitational pull of the moon and sun on the earth's oceans. A tidal power plant consists of a dam or barrage to impound tidal waters, sluice gates to control water flow, and a powerhouse containing turbines linked to generators. Tidal power is a renewable source of energy that produces predictable power without pollution, but has high construction costs and requires suitable coastal locations with adequate tidal ranges.
Tidal energy
Tidal energy harnesses the predictable rise and fall of ocean tides caused by gravitational forces from the moon and sun. It can be generated using two methods: tidal range uses barrages and lagoons to capture potential energy from changing tide levels, while tidal stream extracts kinetic energy from tidal currents using structures like tidal turbines. Tidal energy is a renewable source and more predictable than wind and solar, but development has been limited by high costs and few locations with sufficiently high tidal ranges or currents. New technologies aim to overcome challenges and make tidal power more economically and environmentally viable.
Renewable energy resources
The document discusses various renewable energy resources including solar power, wind power, hydro power, geothermal energy, and tidal energy. For each energy source, it provides details on how the energy is captured and generated, as well as the pros and cons. It notes that solar remains expensive compared to other renewable sources but that technology advances have increased solar penetration. Wind power has become increasingly competitive but output is unpredictable due to weather. Hydro provides base load power but has environmental and location limitations. Geothermal and tidal energy have large-scale potential but also have specific location and cost constraints.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

- 5. ADVANTAGES:- • It is an inexhaustible source of energy. • Tidal energy is environment friendly energy and doesn’t produces greenhouse gases. • As 71% of Earth’s surface is covered by water, there is scope to generate this energy on large scale. • Tidal energy doesn’t require any kind of fuel to run. • The life of tidal energy power plant is very long. DISADVANTAGES:- • Cost of construction of tidal power plant is high. • Tidal energy can be only generated near the coastal regions. • Intensity of sea waves is unpredictable and there can be damage to power generation units. • Influences aquatic life adversely and can disrupt migration of fish.
- 8. ADVANTAGES :- • They are renewable. • They are environment friendly and do not causes any type of pollution. • They are easily predictable. • They didn’t harm or damage the land. DISADVANTAGES :- • It harms the inhabitants and have a huge effect on the marine ecosystem. • It is mainly a source of disturbance for private and commercial vessels. • It has a weak performance in a rough weather. • It is suitable to certain locations.
- 11. • OTEC uses clean, renewable, natural resources. Warm surface seawater and cold water from the ocean depths replace fossil fuels to produce electricity. • Suitably designed OTEC plants will produce little or no carbon dioxide or other polluting chemicals. • OTEC systems can produce fresh as well as electricity. This is a significant advantage in island areas where fresh water is limited. • There is enough solar energy received and stored in the warm tropical ocean surface layer to provide most, if not all, of present human energy needs. • The use of OTEC as a source of electricity will help reduce the state’s almost complete dependence on imported fossil fuels.
