Environment Management Answers To Question Bank
Renewable energy replaces conventional fuels in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services. Need/lamentation of Renewable Energy Innovations: – Fossil fuels when burn, create harmful greenhouse gas emissions and our planet is already feeling the impact of climate change. By using renewable energy instead of silos fuels we would significantly decrease the current levels of greenhouse gas emissions, and this would have positive environmental impact for our entire planet. Renewable energy can improve our energy security by reducing the need for foreign oil import. The global oil market has been characterized by extremely volatile prices and our dependence on oil continues to grow.
By switching to renewable energy and using more domestic renewable energy sources, we would drastically improve our energy security and energy independence. Renewable energy offers variety of different options to choose from. What this means is that countries can choose between sun, wind, biomass, geothermal energy, water resources, etc, depending on the potential and availability of each of these sources. Renewable energy can also give strong boost to our economy in form of new Jobs. The number of people employed within the renewable energy industry is rapidly growing. Renewable energy

In these rural areas renewable energy is much cheaper energy option to satisfy energy needs as compared to traditional energy solutions. Renewable energy can also help improve political ties between countries by sharing technological know-how. Some large renewable energy projects could even be Joined works of two or more different countries. Commercial Advantages of Renewable Energy Innovations: – A] Building Designs: – New buildings should be designed with minimum energy use in mind. Renewable energy measures such as solar thermal / heat pumps / biomass boilers / stoves can then also be considered. Buildings designed to create a comfortable working environment with the minimum of artificial heating, cooling and lighting have lower Energy costs and environmental impacts.
B] Geothermal/Ground Source Heat Pumps: Ground source heat pumps are an ideal solution for heating and cooling in commercial buildings. These systems can collect energy through pipes buried Just below the ground. Also, the running costs are lower. C] Solar Panels: – Solar collectors can be particularly economical for space or water heating in large buildings. Photovoltaic (PA) panels, which convert solar energy directly into electricity, can be used for powering electric fencing or as a backup power where grid supplies are unreliable. D] Landfill Sites: – Landfill sites continue to produce environmentally damaging and potentially hazardous methane emissions.
Collecting this gas for electricity production is a Bio-fuels, derived from a variety of crops and wastes, can be blended with conventional vehicle fuels to produce a greener alternative. Using bio-fuels reduces CA emissions and the use of finite fossil fuels. F] Wind Turbines: – Small wind turbines combined with battery storage can provide a solution to electricity supply problems for small communities and businesses. 5 Reasons of limited growth of Renewable Energy in India:- Growth in the Indian solar sector has slowed down in 2013. The main reason for the slowdown is uncertainties and delays around policies. The new government wants to now push the solar market.
India is an ideal market for renewable energy. It has got a vast potential for generating power from the sun, from wind, from small hydrophone and from biomass. But, Bureaucracy and a lack of dependable and transparent policies are holding back investments. Previously government used to provide 2 types of incentives I. E. ‘Accelerated Depreciation’ (AD) & ‘Generation-Based Incentive’ (GOBI). AD would provide tax-benefits, whereas GOBI would provide incentives for every turbine installation. Both these incentives are withdrawn. Due to this, investors are not turning up. Bottlenecks caused by Indian’s weak grid system are another barrier to higher growth of renewable energy.
Due to weak grid system, the generated electricity cannot be transmitted to the remote and deprived areas. Sluggish market dynamics, lack of holistic vision, absence of long term planning are the other reasons for slow growth of renewable energy in India. Q. 1) b) Carl Fredrick’s ideologies visa-a-visa environment & what major issues are alt in the feature? Carl Frederickson, the protagonist of the movie, worked hard to fulfill his and his passed away wife’s dream of ‘having club house on the cliff facing paradise falls’. He gets disturbed by the heavy arbitration around his house which also forces him to leave his place. He makes makeshift aircraft by using 10000 helium balloons which lifts his house.
He takes his house toward paradise falls which suffers from thunderstorm; destroying few balloons, due to which, his floating house comes closer to hill surface but far away from falls. He drags his house toward falls; during his Journey he comes across his childhood hero Mount who wanted to capture a bird. Mount uses dogs as slaves for capturing bird & controls them through electrical methods. Which shows humans can go to any levels for their wants and wishes. Carl throws all his belongings which he preserves as memories; so that he can fly his house for saving bird. He fights with Mount and saves bird; and helps injured bird to find her chicks leaving them safe in their natural habitat. Also accepts Dug as his own dog. He gives away his belongings, his house, wife memories to save bird and the environment there.
