Repurposing of west virginia strip mines for sustainable
This document discusses potential options for repurposing a former strip mine in West Virginia called Hobet Mine for sustainable energy production. Three main solutions are analyzed: hydroelectric, solar, and wind turbines. For the hydroelectric solution, constructing an upper and lower reservoir with a 300 foot elevation difference could generate 438 MW at an estimated cost of $480 million. A solar farm occupying 2400 acres of the site could generate 150 MW at an estimated capital cost of $166 million. Wind turbines placed on 1800 acres could generate 132GW through 24 turbines, but at a high estimated cost of $234.9 million. Based on metrics analyzing energy output, cost per kW, environmental impact, and social factors, hydroelectric production was determined

The document discusses various renewable energy sources, including solar, wind, hydro, and plant power. It provides details on how these different sources generate electricity. For example, it explains that hydro power uses water flowing through turbines to power generators. Wind power converts the kinetic energy of wind using turbines connected to generators. Solar power can be generated through concentrating solar thermal plants that use mirrors to heat fluid or through photovoltaic panels that convert sunlight directly into electricity. Plant power is an emerging technology that uses living plants to generate electricity through biological and chemical processes in the soil.
Hydroelectric Pumped Storage Potential & Renewable Northwest Integration
Wind generation on Bonneville Power Administration’s (BPA) system in the Northwest grew from almost nothing in 1998 to more than 4,515 megawatts in 2014. The majority of this existing and future potential wind resource is located in the Columbia River Gorge. BPA’s integration of wind is the highest amount as a percentage of load of any utility in the country.
With the clean energy goals of the region and the carbon emissions reductions from the EPA’s proposed Clean Power Plan Section 111(d), the Northwest is facing the retirement of over 3,000-MW of coal-fired generation, further exacerbating the need for dispatchable energy assets.
Wind energy is one of the most affordable forms of electricity today to meet these clean energy and carbon reduction goals. However, the challenges and Achilles’ heel of wind integration lie in the intra-hour variability and uncertainty of wind, making wind energy a difficult resource to dispatch.
The challenge is to find a way to make energy created by intermittent resources like wind and solar energy available on demand to meet current and future load growth. BPA experiences large, unplanned ramping events that occur within the hour and days from several hundred to several thousand megawatts. These large ramps, up and down many times, do not align with when energy is needed by residential and industrial customers.
Hydroelectric pumped storage is a superior solution that offers maximum flexibility to store energy produced on BPA’s system from wind or other renewable resources when it is difficult to utilize these resources on the power grid or integrate them into the power system and to release the energy at a time when it is needed, most often during peak load periods, at a higher value.
Additionally, the present transmission congestion, under or oversupply and overload could be reduced by having a pumped storage project located near significant high-voltage transmission to take advantage of Northwest and Southwest geographic diversity of loads and output from renewable resources, inter-regional exchanges and to mitigate the steep ramping needs, California’s “duck curve,” overgeneration risk and economic de-optimization of the power system.

403
This document discusses the economics of tidal stream power as a renewable energy source. It develops a dynamic optimization model to analyze the costs and impacts of integrating tidal and wind power into electricity grids at different penetration rates. Simulation results for the British Columbia system indicate that renewable penetration rates of 30% would increase electricity costs by 73-150% and the cost of reducing CO2 emissions would be $97.47 to $1674.79 per tonne. The high costs are due to inefficiencies from operating thermal plants at less than optimal levels to accommodate the intermittent renewable sources. The impacts depend on the pre-existing generating mix, with results examined for British Columbia, Alberta and Ontario.

The document discusses the benefits of hydropower as a renewable energy source in the United States. It notes that hydropower currently provides nearly 70% of the country's renewable electricity but that many dams are outdated and in need of rehabilitation to continue providing clean energy. Investing in improvements to existing dams could allow hydropower to generate more power reliably for decades to come while also creating jobs. The document advocates that hydropower should be part of the national discussion on developing renewable energy sources given its clean, reliable and sustainable characteristics.

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.

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
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.

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.
ENVIRONMENT~ Renewable Energy Sources and their future prospects.
This presentation is for us to know that how our Environment need Attention for protection of our natural resources which are depleted day by day that's why we need to take time and shift our attention to renewable energy sources instead of non-renewable sources which are better and Eco-friendly for our environment. these renewable energy sources are so helpful for our planet and for every living organism which depends on environment.
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.

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.
