Here we will be using a normal DC/AC inverter and we will be filtering the output frequency by using a filter circuit. This filter circuit will then output a pure sine wave DC/AC inverted power. Either this is pure sine wave; we cannot directly connect this to the main grid because still this is not high frequency grid tie inverter. Therefore we came up with an idea of a changeover system and so it will switch the main grid and inverter as for the power consumptions. In the inverter design chapter it is clearly mentioned the function of this changeover unit.
Using wind energy would be the best way to solve the world’s pollution problem that cause by burning of fossil fuel. The reason why I personally think that is the best way to solve the pollution is because the wind energy (wind turbine) only uses wind to produce electricity. Wind energy is plentiful, renewable, clean and produce no harmful gas. The effects to the environment are less problematic than the other nonrenewable energy source. It is also cheaper than coal or burning gas.
As it’s prefix suggests, hydroelectricity is produced by the force of water. This means there is no chance of pollution to the atmosphere like there is with dangerous energy sources like natural gas and coal (energy.gov). This process of obtaining energy is not harmful to the atmosphere, unlike the ways fossil fuels are gathered. Due to the fact that toxic fossil fuels are absent in the process of turning the force of water flow into sustainable energy, hydroelectricity is a source of energy that people should be more aware of. “In addition to a sustainable fuel source, hydropower efforts produce a number of benefits, such as flood control, irrigation, and water supply.” (energy.gov).
The single effect thermal vapor compression seawater desalination process is illustrated schematically in Fig. 2. This process uses low-temperature heat source such as waste heat from an industrial process or solar energy to generate fresh water. This system has two distinct advantages: First, it can utilize the low-temperature heat source in the range of 50 °C to 80 °C, which leads to lower grade energy is used. Second, seawater doesn’t need to be heated to a high temperature, which saves energy and reduces scale.
Concentrator solar power concentrates light energy from the sun on a smaller surface to boil a liquid. The steam then spins turbines to generate electricity. This is might be cheaper than using photovoltaics because you don’t need to store the energy for overnight. The thermal storage allows for electricity to be generated for up to 24 hours. There are many types of technologies to do this, for example parabolic trough, compact linear Fresnel reflectors, Stirling solar dish and solar power tower.
A few of these types of energy are: Solar panels, wind turbines and nuclear energy, which all do not release toxic gases. However these energy sources also have pros and cons in multiple ways and aspects, two of them being socially and economically which makes the choice hard on which energy source to invest most in to avoid more problems in our climate. Since solar energy is easy to access and is becoming more popular, therefor in has a lot of potential to become the energy source, which will help reduce greenhouse gases. Nuclear energy: Nuclear energy is an alternative energy that can be used to reduce greenhouse gas emissions. The energy is generated by water that is turned into steam, which drives turbine generators to produce electricity.
Demand side management has to consider the technical, organisational and behavioural solutions that will help decrease energy consumption and demand. These measures are implemented mostly for short term which saves the generator units from being started and shut down at short periods to meet the demand. The benefits of DSM include but not limited to the reduction of customer bill, air pollution, heavy investment on power plants and grid congestion , , . The measures also create job opportunities through innovation and technology to produce energy eﬃcient appliances. The tools used in DSM measures are real time pricing, time of use (TOU) tariﬀ, smart metering and web-based or communication systems .
It just help you to import less from the main grid and cut down on your electricity bills. Pros of Wind Energy: Wind energy has many advantages that help you to provide a source of clean and renewable electricity for everyone. Let’s discuss few of the major benefits of Wind Energy: 1.
The hybrid vehicle is common in the market. It helps reduce tailpipe emission by having two mixtures of engines: an internal combustion engine and an electric motor powered by an electric generator. When the speed of the vehicle is moving at a low rate, the electric motor will automatically engaged and will provide the horsepower to the vehicle so the internal combustion engine is not in use so tailpipe emission is at its minimum. The electric vehicle is also common. It gets energy from an electric grid.
In the picture, it shows the weighing of having solar power and its disadvantage. On the left side, there are trees and solar panels which we can conclude that if we use solar power, we are saving our environment, while on the other hand, we have a huge solar sign that tells us that it will be very expensive. Solar power is arguably the cleanest, most reliable form of renewable energy available, and it can be used in several forms to help power your home or business. Another good thing about solar energy is that it can be used anytime or as long as the sun exists. The disadvantage of having a solar power is that Even though solar cell panels are readily available in most hardware stores and the internet, not everyone is still capable of installing the devices properly.
