This document discusses non-renewable energy sources, specifically fossil fuels such as coal, oil, and natural gas. It provides details on how fossil fuels are formed from the remains of ancient plants and animals, and how they are burned to produce energy. While fossil fuels currently provide the majority of the world's energy needs, they are not renewable and will eventually be depleted if consumption continues to rise. The document also notes some advantages and disadvantages of using fossil fuels.
Coal
Coal provides 21% of the world's energy consumption and is expected to continue powering cities for the next 25+ years until cleaner alternatives can fully replace it. Coal is dug up from mines, crushed into powder, and burned to heat water and create steam that spins turbines to generate electricity. While coal mining provides an important source of energy, it also has environmental impacts and dangers for miners from toxic gases.

Sai coal ppt
Coal is an important non-renewable natural resource that forms from dead plants and animals over millions of years. It is used for thermal energy production, steel manufacturing, cement production, and as a liquid fuel. There are different types of coal that form depending on the conditions during formation, including peat, lignite, bituminous coal, and anthracite. Coal is composed primarily of carbon but also contains other elements like hydrogen, oxygen, sulfur, and nitrogen. Coal is found and mined deep underground, sometimes as far as 300 meters below the surface.
gas pollution by Coal natural fire
Coal seam fires can burn for decades or centuries underground. They are difficult to detect and extinguish, and release toxic gases that contribute to air pollution, climate change, and health issues. Coal fires are a global problem, especially in China, India, and other coal-producing nations where lack of regulation and development have exacerbated the environmental damage. Reducing coal use would help address this issue and provide public health benefits by improving air quality.

Fossil fuel
Fossil fuels are composed of remains of ancient organisms compressed over millions of years. The three main types are coal, oil, and natural gas. Coal is used for heating homes and industry, while oil is refined and used mainly for transportation fuel and plastics. Natural gas is also used for heating and generating electricity. Fossil fuels are non-renewable and their combustion produces pollution, but they currently supply over 80% of the world's energy needs due to being energy dense and easy to transport.
Fuels
This document discusses different types of fuels - their sources, forms and uses. Fuels are substances that produce energy through burning. They exist in solid, liquid and gaseous forms like wood, coal, kerosene, LPG and CNG. Fuels are used for domestic purposes, transportation, electricity generation and operating machines. While fossil fuels like coal and petroleum are non-renewable, renewable sources of energy include solar, wind and biomass.

global warming
This document discusses the causes and impacts of global warming and proposes some solutions to reduce it. It identifies the main causes as emissions of carbon dioxide and other greenhouse gases from burning fossil fuels, deforestation, chemical fertilizers, depletion of the ozone layer, and methane emissions. The impacts outlined include rising sea levels from melting ice, changes in weather patterns, and threats to human health. The document recommends ways to reduce global warming such as using solar energy, fluorescent light bulbs, planting trees, public transportation, and conserving electricity.
Conventional energy sources
The three major conventional energy sources are petroleum, natural gas, and coal. Together they provide about 85% of the country's energy and almost two-thirds of electrical power. While widely used for decades, efforts are made to reduce their environmental impact. These non-renewable resources will be depleted if consumption continues at projected rates.
Fossil fuel powerpoint
Fossil fuels like coal, oil, and natural gas are formed from the remains of ancient organisms. Coal forms from dead plants buried in swamps from the Carboniferous period. Oil forms deep underground as organic material is compressed. Natural gas forms similarly and is used for heating and cooking. Fossil fuels go to refineries to be separated and processed into usable forms like gasoline before distribution. Major oil spills like the Exxon Valdez and Deepwater Horizon damaged ecosystems and local economies through pollution and impacts on tourism.
Ils powerpoint fossil fuels
The document discusses fossil fuels such as coal, oil, and natural gas. Coal forms from dead plants buried under water and dirt that undergo heat and pressure over time. Oil forms from the remains of dead animals and plants from long ago. Natural gas forms from the remains of plankton or other small sea organisms. These fossil fuels provide over 85% of energy in the US and are used to power factories and plants, create gasoline and diesel, and for other purposes like propane, antifreeze, and medicine. The document also briefly discusses refineries and two major oil spills: Exxon Valdez and Deepwater Horizon.
Coal
Coal is formed from peat deposits that are buried deep underground over millions of years. As peat is buried under sediment, it undergoes physical and chemical changes called coalification. During this process, heat, pressure, and bacteria remove oxygen, water, and gases from the peat, concentrating the carbon and transforming it into coal. The deeper the peat is buried, the higher the heat and pressure, resulting in coal that is richer in carbon.
Fuel types
Fossil fuels like coal, crude oil, and natural gas are classified as primary or natural fuels that occur underground. They were formed over millions of years from the remains of ancient plants and animals. Coal is a solid fossil fuel that was formed from plant matter during the Carboniferous period 300 million years ago. Crude oil is a liquid fossil fuel formed from decayed marine organisms and methane is a gas fossil fuel. Fossil fuels are non-renewable resources that are being depleted through human usage.
Fossil fuels
Fossil fuels such as coal, oil, and natural gas are non-renewable energy sources formed from the remains of ancient plants and animals. Coal forms over millions of years as vegetation decays and is compressed. There are different types of coal that vary in carbon content and energy level. Fossil fuels are essential as they currently meet over 85% of global energy demands, being used for heating, electricity, and in various products like plastics and chemicals. However, their extraction and use also carries environmental risks like oil spills, as evidenced by the Exxon Valdez and Deepwater Horizon incidents.
Global warming
This document discusses global warming, its causes, and effects. It explains that global warming is a rise in average temperatures due to increased greenhouse gases trapping heat from fossil fuel combustion. Burning fossil fuels releases carbon dioxide, methane, and nitrous oxide, while industrial processes produce hydro fluorocarbons, per fluorocarbons, and sulfur hexafluoride. These greenhouse gases are accumulating in the atmosphere and causing global temperatures to increase. The effects of this temperature rise include threats to human health, water resources, forests, coastal areas, and agriculture. Individual actions like driving and flying less, recycling more, and using less energy at home can help reduce greenhouse gas emissions and slow the pace of global warming.
8.04 energy and society
Wind energy harnesses the power of wind using turbines, while coal energy burns pulverized coal in power plants. Wind turbines have little environmental impact and minimal hazards, but some oppose their appearance. Coal has significant negative environmental consequences such as air and water pollution. It also poses health and safety risks to miners and plant workers. While wind turbines have higher initial costs, coal energy has increasing mining expenses and wind power is becoming more affordable over time. Overall, the document concludes wind energy is cleaner, safer, and increasingly cost-competitive compared to coal.

It then provides details on various energy sources, both renewable (solar, wind, tidal) and non-renewable (coal, oil, gas, nuclear), discussing their usage and environmental impacts. It also examines global trade in energy commodities and geopolitical factors that influence energy production and consumption.
My fossil fuels ppt
Fossil fuels provide 85% of the world's commercial energy and are primarily made up of coal, natural gas, and oil. Coal is formed from compressed plant matter that died millions of years ago. It is classified based on energy and sulfur content, with anthracite having the highest energy and lignite the lowest. Burning coal produces air and water pollution and greenhouse gases. Natural gas and oil are also fossil fuels formed from decayed sea creatures and are non-renewable. While cleaner burning than coal, extracting and transporting natural gas and oil also causes pollution and health issues. Major oil spills like Exxon Valdez and Deepwater Horizon demonstrated the environmental damage these fuels can cause.

Wind power capacity reached 47,300 MW globally by the end of 2004. Hydroelectric power harnesses the kinetic energy of moving water by using dams to store water in reservoirs and releasing it to spin turbines. Renewable sources have positive impacts like lack of emissions but also negatives like unreliability from varying natural conditions.
globel warming and green house effect
This document discusses global warming and the greenhouse effect. It explains that human activity is increasing greenhouse gases which thickens the layer trapping heat in the atmosphere and gradually increases earth's temperature. The greenhouse effect was discovered in 1824 and the main greenhouse gases are carbon dioxide, methane, CFCs and nitrous oxide. These gases are essential for maintaining a habitable temperature on Earth but human activities like burning fossil fuels have increased their levels since the pre-industrial era. This warming effects ecosystems and humans in various ways like rising sea levels and more extreme weather. Solutions proposed to reduce global warming include using renewable energy, afforestation, energy efficiency and international agreements like the Kyoto Protocol.

Climate Change All over the World .pptx
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
Recycling and Disposal on SWM Raymond Einyu pptx
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
