Presentation on hydropower, wind power and biomass- renewable energy sources in ROMANIA. Made by Romanian student Antonela Pavel, 8th grade, Scoala Gimnaziala Magura.
This document discusses hydropower/hydroelectric power. It defines hydropower as power generated from the force of moving water. It then discusses the different forms of hydro energy, including potential energy from dams and kinetic energy from river currents and tides. Most methods involve directing water through turbines to generate electricity. It also provides information on existing hydropower stations in Pakistan and future proposed projects. Pakistan has significant hydropower potential that remains untapped. Harnessing this renewable resource could help address Pakistan's energy crisis and reduce reliance on expensive imported fuels. However, dams can also negatively impact local environments if not properly planned.
The document discusses the future of energy in Bangladesh. It outlines various renewable and non-renewable energy sources such as solar, wind, geothermal, hydropower, biomass, municipal solid waste, coal, crude oil, and natural gas. For renewable sources, it provides brief descriptions of how each works. It also notes that scientists in Bangladesh have identified reserves of heavy minerals in sea sands. The document is authored by Shamil Arfan Tuhin and is intended to outline energy topics for Bangladesh.
This document discusses hydroelectricity as a renewable source of energy. It is generated using the gravitational force of falling or flowing water to produce electricity. Hydroelectric dams are the most common method of hydroelectric power generation. While hydroelectricity has advantages as a clean energy source, it also has disadvantages such as high construction costs and negative environmental impacts including flooding and changes to local hydrology. The largest hydroelectric dams are the Three Gorges Dam in China and the Itaipu Dam in Brazil.
There are many renewable sources of energy that are more environmentally friendly alternatives to traditional power sources. These include tidal power, which can be generated from tidal stream generators or barrages and has potential for future electricity needs. Wave power generates energy from the motion of ocean waves using floating devices. Solar power harnesses energy from the sun using photovoltaic cells, while wind power uses wind turbines to generate electricity from wind. Hydroelectric power utilizes the gravitational force of falling or flowing water to generate electricity through dams and other means.
Hydropower, or hydroelectric power, generates electricity from the kinetic energy of flowing water. It has been used since the late 19th century and provides around 35% of Pakistan's energy needs. Several large hydropower plants have been completed in Pakistan, including the Tarbela and Mangla Dams, which have capacities of 3,500MW and 1,000MW respectively. Currently, several major projects are under construction like the Neelum-Jhelum Project and Diamer-Bhasha Dam. Hydropower has an efficiency of around 80% and is seen as Pakistan's best solution for meeting future energy demands in a renewable way.
This presentation generally focuses on the pros and cons of hydroelectric power. The visuals and creativity is really high. Moreover a brief on HEP in Pakistan is also taken into account. Thing is, I've given less detail- for the sake of making it look professional. More examples are given below
So basically creating hydropower plants is pretty fantastic for the country as is lead to employment. Hydropower plants create vacancies for managers, technicians, construction workers, marketers, receptionists and many more.
The U.S. hydropower industry currently employs up to 300,000 workers,
In Pakistan the tarbela dam project created about 2500 different jobs from project development to facilities operations and maintenance. which is pretty amazing considering the unemployment problems in Pakistan.
Another benefit of dams is that they not only produce electricity but also saves and reserves water so that the water is not wasted into oceans and seas. So it is like two advantages in a single packet!
Dams can also be used for other purposes like fishing and sports for example by the creation of recreational parks which would bring in
Tourists!
Mega hydropower plants can invite tourists and other machinery enthusiasts to visit the stations and learn some tit-bits about how they function.
The three gorges the largest hydropower plant in the world bought in a crazy number of over 2 million tourists in 2015 brining in 3.5 billion US dollars.
This money in turn benefits the overall economy and GDP of a country and can really turn things around in a third world country like Pakistan.
Thank you!!!

This document describes the process of making a portable solar cooker out of recycled materials. The solar cooker uses aluminum foil to reflect sunlight, plastic wrap to trap heat, and black spray paint to absorb heat. It has a unique enclosed shape with a handle. The process involves cutting polystyrene, covering it with aluminum foil, adding a handle, and spraying it black to create a portable solar cooker that uses principles of light reflection, refraction, and the greenhouse effect to cook with sunlight.
The students made solar cookers from recycled materials at their school to learn about sustainable energy sources. They collected information on solar cookers, constructed panel and parabolic reflector models, and tested them to reach temperatures of 35C and 70C. The students also compared their designs to those of partners in other countries and concluded the project highlighted the environmental and economic benefits of renewable resources.
The document describes a student project to build a solar cooker. It includes:
1) An explanation that a solar cooker uses the sun's energy to cook food by reflecting and concentrating sunlight using a shiny surface.
2) A description of the Latvian student's initial attempts using a lamp instead of the sun, which allowed them to melt a candle and chocolate.
3) Plans for the students to build a improved solar cooker in the spring actually using sunlight, with advice from their science teachers to use a convex mirror to better focus the light.
The document summarizes a hybrid solar box cooker designed to provide a more efficient cooking solution. It discusses how solar cooking can help address issues with traditional rural and urban cooking methods by being cheap, environmentally friendly, and not requiring fuel. The hybrid box cooker aims to reduce cooking time by incorporating a small electric heating element powered by a battery that can be recharged through solar power or a thermo-generator. It is presented as having advantages over existing solar cookers through its compact, weather-proof design with a doneness indicator and potential to access both rural and urban markets.
A solar cooker uses the sun's energy to cook food by reflecting and concentrating sunlight using a shiny reflector, often in a bowl shape. To build your own, you need a shiny reflector surface to direct sunlight onto enclosed food to contain heat and speed up cooking. Using a black pot absorbs more heat than a lighter one.
A solar cooker is an oven that uses sunlight to cook food or boil water by reflecting sunlight off a shiny surface. The document discusses how a parabolic solar cooker works more efficiently by varying its heat levels based on its size, with larger sizes producing hotter heat by reflecting more sunlight using a reflective disc. It then describes how the students created their own solar cooker and details their positive experience with the project.

Sources of Renewable Energy in Romania -by Diana Mujoiu
1.
2. What is Renewable Energy?
Renewable energy is energy that is generated from natural processes that
are continuously replenished. This includes sunlight, geothermal heat, water,
wind, tides and various forms of biomass. This energy cannot be exhausted and is
constantly renewed.
In Romania there are many renewable energy sources, but the most
important are:
Wind power
Sun power
Biomass
Hydropower
3. Wind Power
Romania ranks 10 in the European Union in terms of wind power
production.
The energy produced by wind farms covering 21% of national production
and is the second largest source of electricity.Currently there are 1,000 wind
turbines in Romania.
4. Biomass
Biomass potential in Romania is considerable.
Biomass is one of the logical alternatives for balancing energy.
In Romania it was opened a biomass central CHP of 22MW.
5. Hydropower
Hydro Energy is simply energy that is taken from water and converted to
electricity. The most common method of using energy from water is a
hydroelectric dam. In Romania one of the most important hydro central is Lotru-
Ciunget.
It was put into operation for the first time in 1972 and has a capacity of
510MW.
Hydro central Lotru-Ciunget generates about 30% of total electricity
production in Romania
6. Sun Power
In Romania, solar energy is used to produce heat for hot water consumption
during the warm period. In many places there are already solar houses.
