will happen if you use solar energy to produce electricity. The Bronx should care about solar energy because it will stop the air pollution and no more fossil fuels will be burned, also solar energy is a renewable source which would last more than the fossil fuels being burned in order to produce electricity. Using this alternative resource would be the best for the Bronx because no pollution would be produced and the green houses won't make the global warming. Solar energy would be a good
2.2 Inverters An inverter is a circuit which converts a DC power into an AC power at desired output voltage and frequency. The AC output voltage could be fixed or variable voltage and frequency. This conversion can be achieved either by controlled turn on and turnoff devices (e.g. BJT, MOSFET, IGBT, and MCT etc.) or by forced commutated thyristors, depending on application. The output voltage waveform of an ideal inverter should be sinusoidal. The voltage waveforms of practical inverter are however
of reliable and unreliable sources help sustain life to 7.422 billion people. What gets you from point A to point B? What powers our homes? Electricity and energy are a major use in each and every human beings life. Through our time on Earth, remarkable humans and geniuses of past generations have produced ways to convert these earthy elements to create energy and give us power. There are many ways to convert natural occurrences to energy, such as coal. Coal is a rock, and when it is burnt it can
Project Title: Why is Solar Power Better than Traditional Power? Solar Power might be a popularly growing technology today but the idea of its inception dates back to more than 175 years. It was in 1839 when Alexandre Edmond Becquerel discovered that certain materials produced small amounts of electricity on exposure to sunlight. Later, in 1876 William Adams along with Becquerel’s student Richard Day, discovered that selenium contained potential properties of converting light into electricity. The
discovered the silicon solar cell. This cell actually
They are called solar after the sun because the sun is the most powerful source of the light available for use. Solar cells or PV cells rely on the photovoltaic effect to absorb the energy of the sun and cause current to flow between two oppositely charge layers. A solar panel is a collection of solar cells. Although each solar cell provides a relatively small amount of power, many solar spread over large area can provide enough power to be useful. To get the most power, solar panels have to be
My motivation for higher studies in sustainability is strongly influenced by energy crisis in Pakistan. Energy is considered to be life of any economy. Living in a country suffering from a multitude of problems, especially energy-related problems have proven to be the worse in the past few years. There is very fast and quick increase in demand of energy due to advancement in technology and industry. Now a days some areas of Pakistan are facing 4-6 hours load shedding every day. The main reasons include
SOLAR DRYER FOR HOME APPLIANCE Abstract Solar energy is abundant and more useful for various applications like power productions, battery charging and drying food product etc. The recent case study says that the annual wastage of vegetables and fruits are up to Rs.13300 crores due to not kneading it properly. In olden days open sun drying is the most common method used to preserve fruits and vegetables in most countries. But it has some problem like unprotected from rain, wind-borne dirt and dust
Abstract—This paper describes some ideas about the design of the Scheffler reflectors and how it is developed. Scheffler reflector has wide range of applications where medium and high temperatures are needed. Scheffler fixed focus concentrators are successfully used for medium temperature applications in different parts of the world. These concentrators are taken as lateral sections of paraboloids and provide fixed focus away from the path of incident beam radiations throughout the year. The paper
yield like lower energy cost than any other method. Natural sources of renewable energy are 1. Solar 2. Wind 3. Geothermal energy 4. Biomass 5. Ocean 6. Hydropower 1. Solar energy- Sun is the main source of solar energy. Most renewable energy comes either directly or indirectly from the sun. Using sun radiation, we use solar cooker for cooking food, solar heater for heating water naturally, using solar panels we used to store and generate electricity and variety of commercial and industrial
