Why Renewable Energy Sources is Important?kristahiles111
Renewable energy sources are important because non-renewable resources like coal, oil, and natural gas are being depleted and are expensive and damaging to the environment. Switching to renewable sources like wind, solar, and geothermal energy would provide a sustainable option for the future. Renewable energy can help reduce global warming by limiting carbon emissions and pollution, and can help address the impending depletion of fossil fuels as demand rises. While the initial investment in renewable energy infrastructure may be high, maintenance costs are low and the sources are abundant, making it a financially beneficial option over time.
This document discusses three types of renewable resources: biomass, nuclear energy, and geothermal energy. Biomass acts as a natural battery that stores solar energy as long as it is produced sustainably. Nuclear energy is derived from nuclear fission reactions that split atoms to produce heat and boil water to generate electricity. Geothermal energy uses steam from reservoirs of hot water deep underground to power turbines that generate electricity without fossil fuels.
This document provides information on various energy resources including fossil fuels, renewable resources, and alternative energy sources. It discusses electricity generation from coal, oil, natural gas, as well as renewable sources like hydroelectric, wind, solar, tidal, nuclear, geothermal, and biomass power. Advantages and disadvantages are listed for each type of energy resource.
This document discusses renewable and non-renewable energy sources and their impact on climate change. It classifies various energy sources as renewable or non-renewable and notes that while non-renewable sources like coal and oil are limited and increase pollution, renewable sources can be replenished from natural sources but devices to collect and store this energy can impact the environment and be costly. It questions whether renewable energy can meet global energy demands and compares energy reserves of non-renewable sources to usage.
solar energy--the ultimate renewable resourceGhassan Hadi
Solar energy originates from the thermonuclear fusion reactions of the sun. It represents the entire electromagnetic spectrum that reaches Earth. While solar energy has the advantages of being pollution-free and sustainable, its disadvantages include inconsistent sunshine and its diffuse nature, requiring concentration. Several methods are discussed for harnessing solar energy, including using flat plate collectors to heat water passively or with pumps in an active system. Solar energy can also be used to directly heat buildings through designs incorporating insulation, collection, and thermal mass storage. Additional methods discussed are using power towers or parabolic dishes/troughs to generate solar-thermal electricity, as well as using photovoltaic cells for direct conversion to electricity, though their efficiency and costs remain
The document discusses renewable and non-renewable resources. It defines renewable resources as natural resources that can replenish themselves, such as through biological reproduction, including agriculture, water resources, organisms that provide food/fibers/drugs. Renewable energy sources mentioned include solar, wind, geothermal power. Non-renewable resources are finite and do not replenish in human timeframes, including fossil fuels like coal, petroleum, natural gas. Specific renewable energy sources then discussed in more detail are tidal power, wind power, solar power, hydropower, and thermal energy.
The document discusses various renewable energy resources including solar, biomass, biofuel, geothermal, wind, hydroelectric, tidal, and wave energy. It provides details on different types of biofuels such as ethanol, biodiesel, and biogas which are produced from organic waste sources. Geothermal heating systems are described that use the ground as a heat source and sink. Advantages of various renewable resources are stated as being clean sources that do not contribute to pollution. The conclusion emphasizes creating awareness and using resources sufficiently rather than greedily.

Renewable energy sources like solar, wind, hydroelectric, and geothermal can be replenished and do not cause pollution. Solar cells convert sunlight to electricity but are currently expensive and only efficient at converting 25% of sunlight. Wind turbines use wind kinetic energy to generate electricity but require many turbines to have a large impact. Hydroelectric dams provide reliable power but can flood habitats. Geothermal energy captures underground heat to power generators. Fossil fuels like coal, oil and gas are non-renewable and produce greenhouse gases and other pollution when burned. Nuclear power produces no emissions but creates radioactive waste that remains dangerous for thousands of years.
Energy and energy sources, types, pros and cons are discussed.
Advantages and disadvantages of Renewable and non renewable energy sources are explained.
Renewable resources are natural resources that can be replenished, such as plants, animals, wind, water, and geothermal energy. Humans use renewable resources for food, energy, and power. There are several types of renewable energy including solar energy from solar cells, wind energy from wind turbines, hydroelectric power from dams, geothermal energy from hot underground rock, and nuclear energy from splitting atoms. Each renewable energy source has advantages and disadvantages related to factors like costs, land needs, and pollution levels.

It then describes a biomass briquettes machine that converts loose biomass waste into solid fuel briquettes using a binder-less technology that exploits the self-binding properties of lignin in biomass. These briquettes provide an eco-friendly fuel source that is cheaper than fossil fuels and does not pollute the environment. Contact information is provided for the company that manufactures the biomass briquettes machine.
This document discusses renewable energy and green technology. It defines energy and lists different forms of energy, including electrical, mechanical, chemical, heat, and nuclear. Energy resources are classified as either primary/non-renewable sources like coal, oil, and natural gas, or renewable sources like solar, wind, biomass, and geothermal that recur naturally. Renewable sources are attractive because they are inexhaustible, have low operating costs, are site-specific so transmission is not needed, and cause less pollution than fossil fuels. However, renewables also have disadvantages like low energy density requiring larger plants, intermittency due to varying natural conditions, lower efficiencies, and higher upfront costs.

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.

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.
Climate Change All over the World .pptxsairaanwer024
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
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.
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.
