Renewable Energy Essay – Unlike fossil fuels, which are depleted due to their non-renewable nature, renewable resources can be easily replenished. Wind is an inexhaustible resource because wind is generated by the daily heating and cooling of the earth by the sun. Hydropower is the world’s leading source of renewable energy. It depends on the water cycle, which consists of rain or snow, river water, groundwater, and water vapor. Therefore, the water on the ground is constantly replenished with rain and snow.

Therefore, the water used to drive the turbine can be reused to generate electricity. Renewable energy sources produce little or no greenhouse gas emissions. Geothermal energy produces almost 50 times less carbon dioxide, nitrogen oxide and sulfur emissions than traditional fossil fuel power plants. According to Jacqueline Langwit (“Renewable Energy”), wind turbines and solar photovoltaics can greatly help reduce carbon emissions. Hydroelectric plants also do not pollute the environment, as they do not emit greenhouse gases or other pollutants during the production of electricity.

The costs and financial risks of setting up an efficient wind turbine or biogas plant are high because the current market demand for renewable energy sources is not high enough. It also makes the resource a hard-to-find commodity, even for consumers who want to “go green.” Furthermore, renewables may be environmentally friendly, but their ease of use is not. For example, we need dams to produce hydroelectric power, which can have a serious impact on local wildlife. Because reserves of crude oil, coal, and natural gas are still high, conventional resources are cheaper than renewables.

It is also the easiest to use as well as the most effective resource. All alternatives to gas in transportation, for example, either last shorter or perform worse. Little competition also means it’s easy for consumers to top up compared to renewables, which require a dedicated service provider.

The energy infrastructure of most industrialized countries was built to run on fossil fuels. According to Andy Darvill’s science website, non-renewable fossil fuels provide 66 percent of the world’s electricity and still provide 95 percent of our total energy needs. This includes heating, transport and electricity generation. Existing infrastructure makes it easier to use fossil fuels than renewables, which require more upfront investment. For example, photovoltaic solar panels or wind turbines can be expensive. But existing buildings can get electricity from the grid and existing gas pipelines without new equipment. Non-renewable energy sources can also provide a more continuous supply of energy as long as the fuel exists. Renewable energy sources can depend on erratic or less frequent conditions, such as sunlight to generate solar energy, or wind to power turbines.

One of the long-term problems with the use of non-renewable resources is their lack of sustainability. Eventually, these finite resources will either run out or become difficult to extract, and our energy infrastructure will be deprived of the fuel supplies we need. Of greater concern is the pollution that results from the extraction, processing, and use of these fuel sources. Dangerous levels of air pollution are created by coal-fired power plants and electricity generated by burning petroleum products. Another problem with the use of this type of fuel is the possibility of accidents that can destroy human life and the environment. Although an accident in a coal mine, oil rig, or nuclear reactor is relatively rare, it is very serious. I believe renewable energy is better for El Paso.

I would support it since we get full sun. El Paso could easily support our city with solar power. Also, the fact that we have so much open space can be used to install solar panels, which will ultimately result in a lot of space for energy storage. Basically we only benefit from the sun because we are not near the water and the wind is not that strong. There will be some drawbacks, but they will be offset by the benefits that solar energy will provide.

In today’s world, there are traditional methods of obtaining energy from renewable sources, and many others are used to generate electricity. The world is moving towards renewable energy production because conventional methods are more harmful to the environment, create limited resources and higher costs. Researchers are looking for more diverse methods of converting renewable energy sources into electricity. Power generation using vibration induced vibration (VIV) is the newest technology used in power generation. The kinetic energy of a moving fluid converted into electricity is fundamental.

Traditional production methods using turbines do not work for slow fluid flows. Fluid flow past an inclined body, such as a circular piston, will cause periodic vortices to be shed into the body except at minimum flow velocities. This process produces fluctuating lift and thrust forces which, if the body is compliant or elastically supported, can lead to vortex-induced vibrations. Using this oscillating kinetic energy, electricity can be generated.

Today’s topic will be the Smart Building concept. Its current application areas focus on the use of small self-contained wireless sensors (thus eliminating the need for wires), structural health monitoring, HVAC (ventilation and air conditioning) and building automation.

This project aims to design and develop a power supply unit for wireless sensing and data transmission devices (humidity and temperature) for HVAC applications. It involves the process of harvesting energy from the environment or surrounding system and converting it into electrical energy that can be used to power these sensor devices and transmitters.

Power requirements may vary by application. Applications such as wireless sensing and data transmission devices require a small power range (0.5 mW to 2 W, depending on the device). This project will help eliminate the need for wiring and meet the power needs of small-scale autonomous wireless sensors for HVAC duct systems in smart building concepts. Aims and Objectives Objective Design and manufacture of an energy saving device (0.5 mW – 2 W) using vibration induced vibration Objective Develop a mechanism for converting the energy of a moving fluid into vibrational motion Develop a conversion method for generating electrical energy through vibration Develop a prototype energy harvesting device An energy conversion device is developed to assess effectiveness.R.A.P.

VORTICESHVAC SYSTEMS INTEGRATED WITH AIR CONDITIONING SYSTEMS What is HVAC Heating, ventilation, and air conditioning (HVAC) equipment provides heating and/or cooling for residential, commercial, or industrial buildings. An important requirement of the ventilation system is the ability to operate in both cooling and heating modes. [1]The ventilation and air conditioning system can also act as a supplier of fresh outdoor air and removal of indoor pollutants such as resident odors, volatile organic compounds (VOCs) emitted from indoor furniture, cleaning chemicals, etc. d. A properly designed and maintained system will provide a comfortable indoor environment all year round.1010346191717 Figure 2.1. Installation of ventilation [2] Why air conditioning? When we talk about HVAC systems, there are many important metrics that we need to consider and measure. As energy efficiency and indoor air quality become more important and your customers opt for Internet of Things (IOT) capabilities, sensors are becoming an even more important component of HVAC. Some of these, such as pressure sensors, are most useful for HVAC technology. Pressure sensors play an important role in improving the efficiency of HVAC systems by measuring airflow and pressure throughout the system for efficient air distribution. By measuring the pressure in individual rooms and controlling the airflow in each room, HVAC systems can optimize cooling, heating and airflow in a building and reduce energy consumption. Some of the sensors used in HVAC systems are pressure sensors, ducted smoke detectors, presence sensors, VOC sensors, thermostat sensors. In this project, we will use piezoelectric energy harvesting (PEH) using the vibration-induced vibration (VIV) phenomenon to connect these sensors. Piezoelectric energy harvesting (PEZ) is one of the most promising technologies. It consists of converting mechanical energy into electrical energy or mechanical vibrations into electrical charges. These harvesters produce electricity depending on the amount of force used to compress or deform the material, the amount and type of deformation of the material’s crystal structure, and the speed or frequency at which the material is compressed or vibrated. [2] Using this technology, the design will result in predictable and simple airflow properties. An air conditioning duct system is ideal
