definition, solar radiation is in fact an electromagnetic wave radiation. This makes solar energy a source of pure energy which has in its content the ability to deliver 100% maximum work (maximum exergy), as referred to in thermodynamics. Therefore, solar energy has the highest potential for producing useful work. Whether an application that uses solar energy as input is of thermal nature or independent of temperature, solar energy can be an ultimate choice for a sustainable source of clean energy. In a
ultimate source of energy and its availability allows for various ways to be developed so its free energy can be utilised. A major way in which the energy from the sun (often called solar energy) has been utilised is in the aspect of solar cooking technology (Ahmad, 2001), which is available in different types from the relatively cheap ones with low technology to the big expensive ones that can be used in the industrial heating system or cooking for hundreds of people (Otte, 2013). A solar cooking system
address? Solar energy is significant in our lives and easy to use because sun is an inexhaustible supply. People are now trying to replace the energy sources with solar energy to keep earth clean and to save money. Solar energy is important in many different areas. Plants and animals use solar energy to continue their lives. Most of their cells need solar energy to produce nutrients. The importance of solar energy increased when people understood that they can convert it to convenient energy. Another
amount of uranium could produce large amount of energy as compared to oil or gas and also the transportation of uranium is also less expensive. 2. Reliability of power generation is much high than others as if it is functions properly it could operate for 540 days uninterrupted so no power interruptions makes it more stable. 3. No greenhouse gas emission, as the world is working towards no greenhouse effect nuclear energy is the best source of energy for it. 4. The land requirement of nuclear power
this power world. Energy is one of the basic ingredients required to elevate poverty and socio economic development and energy is an important development of country .today a country can only finish its economy by its power equipment’s and machineries which are working safely if the power continuity is widely available. Pakistan has been facing an unprecedent energy crisis since the last several years .the problem become severe during summers. PAKISTAN’S ENERGY RESOURCES An energy source is a system
Renewable Energy Faldu Smeet (16PGCL005) Renewable energy is energy which is generated from natural process and are continuously available. This includes sunlight, geothermal heat, wind, tides, water and biomasses. Renewable energy can be called as a green energy like as an example of sunlight, which is used for electricity, cooking purposes and it has variety of uses in industry as well as commercial. Renewable energy is money saving because it’s like one-time investment. To build stronger economy
are numerous energy sources available to man for numerous activities that require energy in one form or another. An energy source, such as fossil fuels for example, are natural resources such as coal, petroleum and natural gas that are consumed in the generation of power and from which different forms of energy are obtained (Hubbert, 1948). These sources can be grouped into multiple categories such as primary and secondary; non-renewable and renewable; and finite and alternative energy sources (Hubbert
BACKGROUND INFORMATION A solar powered motorized wheelchair, power chair, electric wheelchair or electric-powered wheelchair (EPW) is a wheelchair that is propelled by means of an electric motor rather than manual power. Motorized wheelchairs are useful for those unable to propel a manual wheelchair or who may need to use a wheelchair for distances or over terrain which would be fatiguing in a manual wheelchair. They may also be used not just by people with 'traditional' mobility impairments, but
The basic ethics of solar water distillation are simple yet efficient, as distillation replicates the way nature makes rain. The sun's energy heats water to the point of evaporation. As the water evaporates, water vapor rises, condensing on the glass surface for gathering. This process removes impurities such as salts and heavy metals as well as eliminates microbiological organisms. The end result is water cleaner than the pure strain water. The Sol Aqua still is a passive solar distiller that only
Answer: 1.1. Relative Advantage:- The SELCO solar systems are more reliable, affordable, and safer to use than the other alternatives available. Products are of higher quality and more durable than the existing other sources. 1.2. Compatibility:-People didn't have the proper effective sources of light and had to rely on the existing alternative sources such as smoky dangerous oil or kerosene lanterns. SELCO used photovoltaic technology to convert solar energy into electricity to light the bulbs. The
