Green Energy

International Journal for Research in Applied Science and Engineering Technology (IJRASET), 2022

Environmental concerns have attracted the attention of a wide variety of countries all around the world. As there is depletion in the non-renewable energy sources and there is concern of the non-renewable energy polluting the atmosphere, the renewable energy industry has emerged as a driver of economic growth and possesses a significant untapped potential for expansion. Realizing the ideal allocation of resources, finding a solution to the problem of overcapacity, and choosing the appropriate manner of selection of Technology is essential

There are a number of different energy sources available in the world. Each of them has strengths and limitations. Five energy sources include Solar Power, Biofuels, Hydrogen, Hydropower, and Geothermal Energy. They are being evaluated for their potential in different parts of the world. The different energy sources exhibit varying levels of practicality. While there is no one solution to the energy problem, hydrogen seems especially promising. All of the world's renewable energy sources have great potential, and the chance to become even better.

Throughout the world, fossil fuels are being used in plentiful amounts and are diminishing the Earth's o-zone layer causing harm to the natural environment in which humans live in.

We know that the Energy is the property of objects which can be converted into different forms or can be transferred to other objects but cannot be created or destroyed. Green energy is the energy that is produced in such a way as to minimize its negative impact on the environment. It is a renewable source of energy. Sources of green energy such as solar, wind, geothermal and hydro energy are developed and promoted as alternative source that make little or no contribution to climate change. In this paper the author seeks to explore how green energy is useful for the future aspect of the world. And current application of this emerging technology, like generating electricity for various purposes, heating and cooling of water and more.

Energy can have many forms-kinetic, potential, light, sound, gravitational, elastic, electromagnetic or nuclear. According to the law of conservation of energy, any form of energy can be converted into another form and the total energy will remain the same. For eg: a laborer when pushes the pile of bags, his potential energy stored inside him is converted into the kinetic energy from the movement of matter or when you burn the wood it's chemical energy is converted into the heat energy or when you charge your mobile phone the electrical energy is converted into the chemical energy which gets stored inside the battery's molecules. The many different natural and renewable energy technologies highlighted throughout the website are by no means breakthrough. Many of the renewable energy technologies have been around for years, and as time goes by, are increasing in efficiency. What are the sources of energy? Energy are broadly classifies into two main groups: renewable and Non-renewable. Renewable Energy Renewable energy is energy which is generated from natural sources i.e. sun, wind, rain, tides and can be generated again and again as and when required. They are available in plenty and by far most the cleanest sources of energy available on this planet. For eg: Energy that we receive from the sun can be used to generate electricity. Similarly, energy from wind, geothermal, biomass from plants, tides can be used this form of energy to another form. Non-Renewable Energy A non-renewable resource is a natural resource which cannot be produced, grown, generated, or used on a scale which can sustain its consumption rate. These resources often exist in a fixed amount, or are consumed much faster than nature can create them. Fossil fuels (such as coal, petroleum and natural gas) and nuclear power (uranium) are examples. In contrast, resources such as timber (when harvested sustainably) or metals (which can be recycled) are considered renewable resources. Why should we conserve energy? Energy needs to be conserved to protect our environment from drastic changes, to save the depleting resources for our future generations. The rate at which the energy is being produced and consumed can damage our world in many ways. In other words, it helps us to save the environment. We can reduce those impacts by consuming less energy. The cost of energy is rising every year. It is important for us to realize how energy is useful to us and how can we avoid it getting wasted. To start saving energy is not a big thing at all. We can start saving the energy from our home itself, just by turning off the lights during day hours, washing clothes in cold water or using public transport instead of using our own vehicle and later can implement these things on much wider scale at society level, then at city level then district level and finally at country level.

The sunlight based earth water still is a gadget to create refined water, by buildup of dampness in the ground. It is basically a traditional bowl sun oriented still, without a base, set specifically on the ground. The dampness on the surface of the ground gets dissipated at the high surface temperature, achieved by the frequency of daylight; the dampness is supplanted by dissemination from underneath the surface and the encompassing soil [3].

Measure of the ability of a body or system to do work or produce a change, expressed usually in joules or kilowatt hours (kWh). No activity is possible without energy and its total amount in the universe is fixed. In other words, it cannot be created or destroyed but can only be changed from one type to another. The two basic types of energy are (1) Potential energy: Potential energy or stored energy is the ability of a system to do work due to its position or internal structure. For example, gravitational potential energy is a stored energy determined by an object's position in a gravitational field while elastic potential energy is the energy stored in a spring. It is associated with the nature, position, or state (such as chemical energy, electrical energy, nuclear energy).

Renewable energy is the energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished). About 16% of global final energy consumption comes from renewables, with 10 coming from traditional biomass, which is mainly used for heating and from hydroelectricity. New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 3rd are growing very rapidly. The share of renewables in electricity generation is around 19%, with 16% of global electricity coming from hydroelectricity and from new renewables.
