Renewable source of energy

The development of technology combined with the surge in population has led to a new era of living that has increased energy demand. Fossil fuel has been the main energy source for so many years, but it is no longer sustainable with its depletion and negative consequences. A need has arisen for a replacement resource to replace the depleting fossil fuels using right now. This need is what pushes us towards renewable energy. An examination of renewable energy sources: their uses, potentials, and limitations, as well as their effects on the climate and human health, is presented in this work. As...

The problem of global warming is a problem facing the world community. Since the Industrial Revolution’s birth, the use of energy from fuel oil (FF) has surged, and this causes an increase in Greenhouse Gases (GHGs) resulting from burning fuel. This GHG is the cause of the rise in the earth’s temperature, which is estimated to one day, the earth is not comfortable and even no longer habitable. The solution to the problem is reducing GHGs that can be done by saving fuel use, which is replaced with renewable energy sources (REs). RE sources are obtained from the Solar Power Plant (SPP), Wind Ene...

Stochastic, that is to say, the uncontrollable varying of oil prices on the world market, is the cause of considerable concern not only to energy engineers but also of common people. The reason is as simple as that: the price rise per oil barrel on the world market affects the increasing cost of living for all of us. Recently, we have witnessed the rocketing oil price which had no sooner risen to 160 US $ per barrel, when in only a several days it fell to 50 US $.

The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels (i.e., coal, petroleum and natural gas) and other conventional resources, presently being used for generation of electrical energy, may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy of the world. Also generation of electrical power by cold based steam power plant or nuclear power plants causes pollution, which is likely to be more accurate i...

Integration of renewable energy sources involves integrating in a system any energy resource that naturally regenerates over a short period of time. This time scale is derived directly from the sun (such as for themal, photochemical, and photoelectric energy), indirectly from the sun (such as for wind, hydropower, and photosynthetic energy stored in biomass), or from other natural movements and mechanisms of environment (such as for geothermal and tidal energy). A renewable energy source cannot run out and causes so little damage to the environment that its use does not need to be restricted. ...

This research work is devoted to the issue of studying the key risks of switching to renewable energy sources. The relevance of the topic of work is determined by the fact that, according to climatologists [5], climate change, which has a negative impact on the environment, is caused by the emission of greenhouse gases such as carbon dioxide (CO2). For this reason, measures to prevent or reduce greenhouse gas emissions are at the heart of the energy transition. International treaties such as the Kyoto Protocol and the Paris Agreement lay the foundations for global action to combat climate chan...

The article analyzes the problems and risks of new-fangled renewable energy sources in the 21st century, which can radically change the energy picture of the world and to a certain extent reduce the risk of climate change. However, energy generation from wind is usually available 25—35% of the time, from the sun — 10—25%.Renewable energy sources (RES) face the problem of accumulating or supporting capacities that should replace the unstable generation of RES at the time of inevitable failures. RES cannot exist without excess reserve capacities on traditional energy carriers that can quickly in...

The improvisation of renewable energy sources is of global concern as there is foresight in the depletion of fossil fuels. This is because there is dependence on energy fuel consumers over time and the detriment on the biotic and abiotic component of the environment is alarming. The need for an alternate source of energy source is imperative. Several options have been considered by the scientific community, especially biofuels which hinges primarily on the type of biomass. Agro waste is most considered because of its abundance but it is competed for as feeding purposes in humans and animals. H...
