Concept of Cogeneration
Summary on Cogeneration
Cogeneration is the simultaneous production of power/electricity, hot water, and/or steam from one fuel. Cogeneration plant can reach system efficiencies exceeding 60%. Cogeneration is an enery-efficient, environmentally-friendly method of producing electricity steam and/or hot water at the same time, in one process with one fuel. It is a way of recycling energy.
Molasses which is obtained from sugar is used together with fossil fuel to produce the heat energy like steam and hot water. This process produces electricity which can be used in the power plant itself or be sold on a wider range that is to the population. The heat energy can be used to burn bagasse to produce ethanol.
It reduces fuel cost. This type of power can be used in various domains like schools, commercial laundries, nursing homes and in many others. It is Energy independence from foreign suppliers. Cogeneration can result in a cleaner, greener, healthier environment as lower emissions to the environment, in particular of CO2, the main greenhouse gas. In some cases, biomass fuels and some waste materials such as refinery gases, process or agricultural waste are used. These substances which serve as fuels for cogeneration schemes, increases the cost-effectiveness and reduces the need for waste disposal. It is moreover an opportunity to move towards more decentralized forms of electricity generation, where plants are designed to meet the needs of local consumers, providing high efficiency, avoiding transmission losses and increasing flexibility in system use. This will particularly be the case if natural gas is the energy carrier.
Cogeneration is a fairly new technology in Africa, and only a few countries have ventured into the technology. Mauritius is the leader in Africa's cogeneration projects.
"Mauritius meets close to 40% of its electricity needs from cogeneration, of which 25% is from bagasse (sugar cane waste)," – Stephen Mutimba (MD for sustainable energy in

    But then again that equals one thousand million tons of oil each year, which is pretty cool. Biomass is used mostly in in developing countries such as Kenya, which 75% of their energy comes from biomass. Then other more populated countries also have a good number of used biomass. India uses 50%, China 33%, then Brazil uses 25%. The United States, being a rich country uses only 3% of biomass. Which is sad because to have a better future the states should use more biomass.…

    Energy is an important part of our everyday lives. Energy can come in many different types, and forms it can be used for many different purposes. Energy has many different usages and can be converted from one form of usage to another form of usage depending on what the need is. One form of energy conversion is the use of food to supply people's bodies with energy. Another form of energy is how coal is converted into electricity. Fuel is another form of energy that can be used for many different usages as well. Fuel is used for much different reason such as allowing our cars to function and our lawnmowers to cut grass. There are many different reasons why people use energy in the many different ways that we use it. Even though people rely on energy usage, some of the forms of energy we use are very harmful to the environment and even dangerous to ourselves. The harmful and dangerous fuels that we use can be changed to alternative methods of energy usage. There are two different types of alternative energy, which is known as renewable energy. Renewable energy is very resourceful and is able to be used because it is all around us there will not be a shortage of material and it is safer on every living thing and being. Energy and fuel usage just like everything else in the world has its advantages and disadvantages about using it. We must collectivity figure out which source of energy is right for everyone but for now we will find out which is best to use in your…

    In the United States and around the world, demand for energy is growing significantly. Climate change and environmental regulations continue to push against the need for increasing energy generation. In the U.S., natural gas has become a popular alternative fuel source for power plants. It is also recognized for its ability to heat homes and serve as fuel for motor vehicles. Natural gas could greatly reduce the United States reliance on oil and coal.…

    Energy is an important factor in todays society, it is neccesary to power business, manufacturing and the transportation of goods and services all around the world. Solar powered energy is energy from the sun. This energy can be conerted into different energy like heat and electricity. Heat can be used to heat water or heat spaces, for example heating for houses, buildings or even swimming pools. Solar energy can be converted in two ways, by Photovoltaic or “solar cells” which change sunlight directly into electricity or by concentrating solar power plants which generate electricity by using heat from solar thermal collectors. Coal powered energy has played an important role in the advancement of civilization and will continue to be a major fuel source for at least the next quarter century. It is used primarly to produce electricty and heat through a dirty process which involves mining and combustion of the fuel. The two most common types of coal mining used today are surface mining and underground mining. In the long run, solar energy has greater potential than coal powered energy.…

    In the novel, A Tale of Two Cities, Charles Dickens uses weather to describe the mood of the scene and the emotion in the characters thus reinforcing the motif of darkness and the light by using the golden thread to bring Mr. Manette out of darkness or lighting up a dark and gloomy room. Ms. Lucie Manette is the "eternal light" (Dickens 47) towards all darkness in the many lives she has walked into with "her golden hair" (Dickens 42). When Lucie was first introduced to her long lost father, One Hundred and Five North Tower was sitting in a “dim and dark” (Dickens 37) depository but when Lucie emerged from the doorway “a broad ray of light fell into the garret”(Dickens 38). Lucie "was the golden thread that united [Dr. Manette] to…

    Ethanol is made by mixing yeast with plant material and kept warm. Yeast is a unicellular organism whose diet is made of plant material. Sugars are turned into alcohol by the yeast. This process, used in producing ethanol, is called fermentation. Primarily corn is used to produce ethanol in the United States. Ethanol creates less polluting gases than gasoline or diesel. Mixing gasoline and ethanol can help decrease pollution. Brazil is the world’s largest ethanol producer (Solway 12). Ethanol is produced from sugarcane in Brazil. The sugarcane is crushed to extract the sugar. Then the sugar is dissolved. Vehicles in Brazil run on a higher concentration of ethanol than vehicles in the United States. The remnants of the sugarcane is referred to as bagasse. Dried bagasse can also be used as fuel (Solway 13). Power plants may burn bagasse to produce electricity. Sugarcane can produce the power needed to keep the ethanol plant running and the sugar to make ethanol.…
