Electric cars were first invented in the 1830s but did not become popular until more recent developments. Electric cars use electricity instead of gasoline to power an electric motor, providing benefits like being eco-friendly, safe, and inexpensive to fuel while avoiding emissions. They consist of main components like lithium-ion or lead-acid batteries to store energy, an electric motor to convert it to movement, and a controller to manage the power flow. While electric cars have advantages in reducing emissions and fuel costs, their shorter driving ranges and need for charging infrastructure can be drawbacks compared to gasoline vehicles.

agriculture, a great amount of energy such as coal, oil
and gas has been consumed in the world. Extensive
use of these fossil energies deteriorates a series of
problems like energy crisis, environmental pollution
and so on. Everybody knows that the fossil energy
reserves are finite, some day it will be exhausted.
It is possible that the world will face a
global energy crisis due to a decline in the
availability of cheap oil and recommendations to a
decreasing dependency on fossil fuel. This has led to
increasing interest in alternate power/fuel research
such as fuel cell technology, hydrogen fuel, biodiesel,
Karrick process, solar energy, geothermal energy,
tidal energy and wind. Today, solar energy and wind
energy have significantly alternated fossil fuel with
big ecological problems.
With the development of the science and
technology, power generation using solar energy and
wind power is gradually known by more and more
people. And it is widespread used in many developed
countries. The merits of the solar and wind power
generation are very obvious-infinite and nonpolluting.
The raw materials of the solar and wind
power generation derived from nature, and wind
power generation can work twenty-four hours a day,
solar power generation only works by daylight. In
addition, this kind of power generation has no
exhaust emission and there is no influence to the
nature. But it also has some shortcomings. Because
of the imperfect of the technology, equipment of the
solar and wind power generation is very expensive.
By far, it cannot be widely used.
In addition, solar and wind power
generation system affected by the changing of the
weather very much, so it has obvious defects in
reliability compared with fossil fuel, and it is difficult
to make it fit for practical use the lack of economical
efficiency .Because of these problems it needs to
increase the reliability of energy supply by
developing a system which interacts Solar and wind
energy. This kind of system is usually called windsolar

Power generating using Regenerative Braking system ppt
Regenerative braking is a system used in hybrid vehicles to capture kinetic energy during braking that would otherwise be lost as heat. The system uses the electric motor to act as a generator during braking, converting the energy into electricity that is stored in the vehicle's batteries. This captured energy can then be used to help power the electric motor, improving the vehicle's efficiency. Regenerative braking provides benefits like greater fuel economy and emission reductions compared to traditional braking systems that waste energy as heat. While more efficient, regenerative braking systems still lose some energy through heat and resistance in transferring and storing the captured kinetic energy in the batteries.

This document discusses the history and development of electric and hybrid vehicles. It begins by covering early electric cars in the 1900s which were clean and easy to use but had limited range. Early hybrid cars from 1900 combined the advantages of electric drives with longer range by adding gasoline engines. Gasoline cars became dominant from the 1920s due to their low costs, mass production, and performance. Interest in electric vehicles revived in the 1960s and hybrids reemerged in the 1970s as battery and electronics technology advanced. The modern hybrid designs of Toyota and Honda combine gasoline engines with electric motors and batteries to improve efficiency and reduce emissions compared to conventional vehicles. The document discusses the energy storage challenges of batteries compared to liquid fuels and outlines the
Electric automobile
Electric vehicles were pursued early in the 20th century but gas-powered cars became dominant due to easier mass production. Interest revived in the 1960s due to environmental concerns, but high battery costs remained a challenge. Modern electric cars are purpose-built from the ground up with lightweight materials and aerodynamic designs to maximize energy efficiency and range. Batteries, electric motors, and regenerative braking systems are optimized while passenger comforts are retained.
Batteries in electric vehicles
Electric vehicles first debuted in 1890 but became rare after Henry Ford mass produced gasoline-powered Model Ts in 1908. Interest revived in the 1990s after laws promoting electric vehicles. Early models included GM's EV-1 but production costs were high. The Toyota Prius, introduced in 1997, was the first mass-produced hybrid. Batteries have transitioned from lead-acid to more advanced lithium-ion types, improving energy density. Lithium polymer batteries currently offer the highest energy and power density and flexibility, making them well-suited to power electric vehicles.

Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
