Man does harm to the climate, water, ground, the different components of the world, and to nature itself, all round. There is just so much man-made waste and environmental destruction that the uncertainty waiting is sufficiently anxious to wake us up. A few developments are taking place from a climatologically standpoint of the overall scenario. Our national and regional climates are both highly polluted. In the densely developed elevations of the northern latitudes, the defensive ozone layer is fading twice as quickly as scientists assumed several years earlier. The accumulation of greenhouse emissions would contribute in the immediate term to major shifts in climate conditions due to global warming. The consequences of environmental degradation are on not only humans, but also on other living creatures as well as the natural world. The issue of environmental contamination and waste disposal will be discussed in this article. All that surrounds us is linked to the environment knowingly or unknowingly. The author of this paper is expressing in what condition our environment is now. What measures can be taken to preserve our environment? Furthermore, he discusses how renewable energy is a boon for our planet that may be proven to be a boon if individuals use it effectively.

Energy is considered as a key source for the future and plays a pivotal role in its socioeconomic development by raising the standard of living and the quality of life, not only for India but also for the world. In view of the scarce fossil fuel reserves, solar energy is one of the important sources of renewable energy used in India because of the suitable climate conditions. It receives about 5485.17 Wh/m2day of solar insolation with an annual total of about 19, 74, 661.2 Wh/m2. Except for the monsoon months, solar radiation incidence is very encouraging, from the application point of view. For the efficient functioning and better performance of solar energy device, the information of solar radiation and its components at particular location is very essential for designing the solar energy devices. Therefore, over the years, several empirical correlations have been developed in order to estimate the more appropriate solar radiation in India as well as around the world. Here we present a review of different solar radiation models which predict global solar radiation and discussed the long-term plan to meet future energy demand with renewable energy due to economy growth.

History Of

‘What are renewables?’ defines renewable energy and provides a brief history of its use. It focuses on energy generated by solar, wind, and hydropower. These energy sources are renewable, in the sense that they are naturally replenished within days to decades. Only a few years ago, giving up our reliance on fossil fuels to tackle global warming would have been very difficult, as they are so enmeshed in our society and any alternative was very expensive. Nearly all of the sources of energy up to the 18th century were from renewables, after which time the world increasingly used fossil fuels. They powered the industrial revolution around the globe, and now provide most of our energy. But this dependence is unsustainable, because their use causes global warming, climate change, and pollution. Other than hydropower, which grew steadily during the 20th century and now provides almost a sixth of the world’s electricity demand, renewable energy was a neglected resource for power production for most of this period, being economically uncompetitive. But now, renewables are competitive, particularly through the support of feed-in tariffs and mass production, and governments are starting to pay more attention to clean energy, as the threat of climate change draws closer. Moving away from fossil fuels to renewables to supply both heat and electricity sustainably has become essential.

The generation of solid waste around the world creates problems if not properly managed. The method of processing solid waste by burning or landfill is currently not optimal. The availability of land where the final processing (TPA) is critical, looking for a new TPA alternative will be difficult and expensive, especially in big cities. The processing of solid waste using bio drying technology has the potential to produce renewable energy and prevention of climate change. Solid waste processing products can serve as Refuse Derived Fuel (RDF), reduce water content of solid waste, meningkatkan kualitas lindi and increase the amount of recycled solid waste that is not completely separated from home. Biodrying technology is capable of enhancing the partial disintegration and hydrolysis of macromolecule organic compounds (such as C-Organic, cellulose, hemicellulose, lignin, total nitrogen). The application of biodrying has the potential to reduce greenhouse gas emissions such as carbon dioxide (CO2), methane (CH4), and dinitrooksida (N2O). These gases cause global warming.

Dramatic Shift

Purpose – The world is undergoing a dramatic shift in climate conditions. A heated debate is on-going over what measures to take in order to overcome the global-warming-related temperature increase, now more than 2 degrees centrigrade. The article tries to evaluate the contribution of the feed-in tariff (FIT) and the price of components for solar plants to the accumulation of new solar capacities in Germany, with the aim of determining the reasons for a drastic decline in the new capacities, observed since 2012. Methodology – An autoregressive integrated moving average (ARIMA) is used with the new PV Capacities as a dependent variable and component prices and feed-in-tariffs as independent variables. Data from German Federal Network Agency is used. Findings – The statistical analysis shows a significant effect of component prices (in EUR per watt) and the value of the FIT (in EUR) on the New PV Capacities. As Germany has not reached the postulated yearly increase rate of New PV Capacities of 2500 MW since 2014 (EEG, 2017), new approaches are necessary to overcome this situation

<p><strong>Abstract.</strong> The world has been alarmed with the global warming effects. Global warming has been a distress towards the environment, thus shorten the Earth’s lifespan. It is a challenging task to reduce the global warming effects in a short period, knowing that the human population is increasing along with the electricity and energy demand. In order to reduce the effects, renewable energy is presented as an alternative method to produce energy in a way that will not harm the environment. Oil palm is one of the agricultural crops that produces huge amount of biomass which can be processed and used as a renewable energy source. In 2016, Malaysia has reported over 5 million hectares of land were covered by oil palm plantations. Placing Malaysia as the second largest country of oil palm producer in the world has given it an advantage to produce renewable energy source. However, there is a need to monitor the sustainability of oil palm plantations in Malaysia via effective mapping approaches. This study utilised two different platforms (open source and commercial) using a machine learning algorithm namely Support Vector Machine (SVM) to perform oil palm mapping. An open source Python programming-based technique utilising Scikit-learn module was performed to map the oil palm distribution and the result produced had an overall accuracy of 91.39%. To support and validate the efficiency of the Python programming-based image classification, a commercial remote sensing software (ENVI) was used and compared by implementing the same SVM algorithm and the result showed an overall accuracy of 98.21%.</p>

The World

The bottom billion has missed out on global prosperity. The current reality for these people is poverty; the issue is whether this will also be the fate of their children. The path that the rest of the world took to lift itself out of poverty—industrialization—is proving much more difficult for these latecomers. Industry has globalized, and China’s combination of huge scale with low wages makes it hyper-competitive when pitched against new entrants. Farming offers them little promise. In Africa, home to most of the bottom billion, agricultural productivity has already fallen far behind international standards. Global warming is likely to widen the gulf, making Africa even hotter and drier, while warming the vast tracts of North America and Eurasia that are currently too cold for cultivation. Nor is aid likely to rescue them; it is under increasing attack, sometimes for good reason, and is being squeezed by the need to rein in fiscal deficits. The countries of the bottom billion have one lifeline: nature. Nature has the potential to lift most of them to prosperity. But nature does not come on a platter. Mankind was not born into an Eden, but into a harsh environment in which we struggled to survive even in tiny numbers. Gradually the natural world has become more valuable to mankind as technology has progressed. Technology turns nature into an asset. However, technology alone merely gives those assets the potential to be valuable to society. Natural assets have no natural owners, and as they become valuable they can trigger a struggle for possession in which their value is dissipated in the costs of struggle. Prehistory was violent; some anthropologists estimate that around 40 percent of deaths were due to fighting. As technical discoveries conferred value on rare natural phenomena such as flint, disputed ownership was inevitable. Basic economics tells us that the value of the effort put into getting possession of natural assets would escalate until it was approximately equal to the value of the assets to be acquired.

The article analyzes the dynamics of consumption of primary energy and production of electrical energy in the world for 1973-2012 and the volume of renewable energy. It is shown that in the crisis year of 20 0 9 there was a significant reduction in primary energy consumption and production of electrical energy. At the same time, renewable energy has developed rapidly, well above the rate of the world economy growth. The development of renewable energy is one of the most effective ways out of the crisis, taking into account its production regime, energy, environmental, social and economic efficiency. The forecast for the development of renewable energy for the period up to 2020, compiled by the IEA, is analyzed. It is shown that its assessment rates are conservative; the authors justify higher rates of development of renewable energy.

This chapter examines Merata Mita’s Mauri, the first fiction feature film in the world to be solely written and directed by an indigenous woman, as an example of “Fourth Cinema” – that is, a form of filmmaking that aims to create, produce, and transmit the stories of indigenous people, and in their own image – showing how Mita presents the coming-of-age story of a Māori girl who grows into an understanding of the spiritual dimension of the relationship of her people to the natural world, and to the ancestors who have preceded them. The discussion demonstrates how the film adopts storytelling procedures that reflect a distinctively Māori view of time and are designed to signify the presence of the mauri (or life force) in the Māori world.
