Conventional & non conventional By: MOULIK AGRAWALMøûlîk Ägràwâl
This document discusses conventional and non-conventional energy resources. It defines conventional resources as those used for energy since ancient times, such as coal, natural gas, oil, and firewood. These resources form over long periods from decaying organic matter but release stored carbon and greenhouse gases when burned. Non-conventional resources discussed include solar, wind, hydroelectric, geothermal, bioenergy and tidal power. These resources are abundant, renewable, and can be supplied to both urban and rural areas without pollution.
The document discusses three renewable energy sources: wind power, wave power, and geothermal energy. Wind power uses wind turbines to generate electricity from air flow and has large potential but can threaten wildlife. Wave power captures energy from ocean waves to generate electricity or desalinate water, though the technology is still developing. Geothermal energy uses heat from within the earth and has few emissions, but prime sources are location specific and far from population centers.
This lesson plan discusses 10 sources of energy: solar, wind, geothermal, hydrogen, tidal, wave, hydroelectric, biomass, nuclear, and fossil fuels. The objectives are for students to justify their choice of most reliable energy source and explain the importance of conserving energy. Students will group according to their preferred energy source, debate the efficiency and convenience of different options, and research pros and cons of the 10 sources in an assignment. While each source has benefits, all have flaws, so a balanced approach using multiple sources is needed.

The goals of green technology are to meet needs sustainably without damaging resources or the environment through reducing waste and recycling materials. Its key advantages are energy savings, being environmentally friendly, cost effectiveness, power savings, and allowing for reuse of natural resources.
This document discusses types of resources, problems with non-renewable energy, and methods to reduce pollution and conserve resources. It defines renewable and non-renewable resources and examines fossil fuels, pollution, acid rain, and global warming. Suggested solutions include using alternative energy sources, reducing pollution emissions, improving energy efficiency, and recycling resources.
Renewable and Non- renewable energy SourcesGeorge Thomas
Renewable energy is energy which is generated from natural sources i.e. sun, wind, rain, tides and can be generated again and again as and when required. Non-Renewable energy is energy which is taken from the sources that are available on the earth in limited quantity and will vanish fifty-sixty years from now.
The document declares 2012 as the International Year of Sustainable Energy for All and discusses various renewable and non-renewable energy sources such as solar, wind, hydropower, biomass, nuclear, and fossil fuels. It notes that 20% of the global population lacks access to electricity and 2.7 billion people depend on wood, charcoal or animal waste for energy, advocating for a sustainable "Energy Plus" approach to provide energy access for the poor.

Energy is the ability to do work or cause change and comes in different forms. Non-renewable energy sources like coal, petroleum and natural gas are fossil fuels found underground that were created over millions of years and are being used faster than replaced, so will eventually run out. Renewable sources of energy like the sun, wind and water are constantly available and will never deplete as they are replenished naturally. The document discusses key renewable and non-renewable energy sources and ways to conserve energy.
The document discusses both the pros and cons of technology's impact on the environment. On the pro side, it outlines various renewable energy technologies like hydroelectric, wind, solar and geothermal that can help reduce environmental impact. However, on the con side it notes that climate change poses an existential threat if carbon emissions are not reduced rapidly. Certain existing and potential technologies also risk catastrophic destruction if misused, like nuclear weapons. In conclusion, the effect of technology on the planet remains uncertain, but renewable technologies need further development while curbing climate change and limiting weapons proliferation.

CAMBRIDGE GEOGRAPHY A2 REVISION - ENVIRONMENTAL MANAGEMENT: SUSTAINABLE ENERGY SUPPLIES. Presentation suitable for Cambridge A2 level students. It contains: key terms and definitions, topic summary, additional works and suggested websites.
The document discusses renewable energy sources as alternatives to non-renewable energy sources that damage the environment. It summarizes various renewable energy sources such as solar, wind, hydroelectric, biomass, geothermal, and fuel cells. India has potential to harness energy from these sources to meet its growing energy needs in a sustainable manner. However, it currently utilizes renewable sources like solar and wind at a very low capacity compared to its potential. More research and efforts are needed to promote the increased use of renewable energy.
The document outlines the agenda for an environmental science class which includes:
1) Collecting and returning graded quiz papers, discussing current events, and presenting on topics related to the earth's poles and fossil fuels.
2) Covering topics like the environmental impacts of extracting and burning fossil fuels such as coal, oil, and natural gas. Coal mining can pollute air and water while oil and gas production causes land disturbance and increased greenhouse gas emissions.
3) Discussing different strategies for the US energy system, including energy efficiency, developing alternative energy sources, addressing environmental damage from fossil fuel production, and securing future fossil fuel supplies.
Presentation On Green Economy For Sustainable DevelopmentAsif A. Kabani
The document discusses transitioning to a green economy. It defines a green economy as one that improves human well-being and equity while reducing environmental risks. A green economy is low-carbon, resource efficient, and socially inclusive. It explores the relationship between sustainable development and poverty reduction. The document also discusses greenhouse gases, their sources, and their impact on climate change. It notes that human activities like burning fossil fuels and deforestation have increased the atmospheric concentrations of greenhouse gases.
This document discusses and compares various sources of renewable and non-renewable energy. It outlines the benefits of renewable sources like solar, wind, hydroelectric, geothermal and biomass energy over fossil fuels. While renewable sources have upfront costs, they have lower long-term costs, cause less environmental damage and are sustainable. Fossil fuels are rapidly depleting and their extraction and use produces significant pollution and greenhouse gases. Overall, the document argues that renewable sources are a better option for meeting energy needs due to their economic and environmental benefits.
This document discusses several renewable and non-renewable energy sources:
- Fossil fuels like coal, oil and gas currently supply 90% of the world's energy but are being depleted 100,000 times faster than they can be replenished. Their use also releases greenhouse gases and pollution.
- Biomass energy from waste products could help reduce fossil fuel usage and delay depletion if used alongside other renewable sources.
- Geothermal energy taps heat from within the Earth and some believe it could replace fossil fuels for heating applications, though it may not generate enough energy to replace coal.
- Wind power capacity has doubled in recent years and turbines can harness wind almost anywhere, but intermittent wind means it could not
The document discusses strategies for mitigating the effects of rising sea levels in a coastal city. It recommends the following plan of action:
1. Implement adaptation strategies like building dikes and barriers to protect coastal areas from sea level rise, and help coastal populations relocate to higher ground.
2. Pursue mitigation efforts like improving energy efficiency, expanding renewable energy and public transport, and reducing emissions from buildings, transportation, waste, and land use to slow the rise in sea levels caused by climate change.
3. Educate the public about sustainable practices they can adopt to reduce their carbon footprint, like using less energy and materials, recycling and composting more, and opting for more sustainable transportation
Technology can both cause and fix unsustainable resource use. It causes issues like pollution from producing and using technologies that consume significant resources. However, technology can also help replace unsustainable resources with renewable alternatives like hydroelectric power. For example, in China technology improved coal plants to burn coal cleaner. Additionally, China built the massive Three Gorges Dam to generate hydroelectric power and replace coal, though it had environmental and social impacts. Overall, while technology can contribute to unsustainable resource use, it also provides solutions by enabling more efficient use of resources and alternatives to replace unsustainable options.
This document discusses the importance of protecting the environment and implementing more sustainable practices and technologies. It notes that while many appreciate nature's beauty, many do little to protect it as land is developed with little regard for the environment. The document then outlines various strategies proposed in "Plan B" to reduce carbon emissions through increased energy efficiency and renewable energy adoption, including more efficient lighting, appliances, buildings, transportation, materials recycling, and smart grids. It also discusses utilizing wind, solar and geothermal energy instead of fossil fuels. The document concludes by stating that widespread dedication is needed to implement solutions and ensure a sustainable future through reduced emissions.

Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
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.

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.

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...Joshua Orris
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.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
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.
