Evaluation of Green Technology and the Potential for Environmental Benefit

It is important to first recognize that for the most part human kind has ceased to acknowledge the sacred commonality we beings share with the rest of nature. How much this may have to do with the idea that by our birth in we have in fact “sinned” ignores the fact that as we are one with nature we therefore have in fact never left the “father”. By first awakening to this fact would of course greatly expedite human kinds realization of what needs to occur in order to realign our purpose with the natural order.

To arrive at an informed decision point and to choose an appropriate environmentally correct technology, requires that a number of very essential evaluations be made, primary among which are, first to select categorically, the appropriate energy source that best matches the “work” to be performed. While this seems obvious one need only look at the case of ethanol from corn to understand what we are talking about. Not only is ethanol a poor choice of fuel for reason of the inability to transport it via existing pipelines, it produces significantly lower BTU’s than gasoline and cannot be used as a stand alone fuel to power existing reciprocating combustion engines. But probably a more significant issue is the impact on corn availability as a food staple and the resulting escalation of prices in the market.

The principle method for measuring the EROEI or Energy Return On Energy Invested is based upon a calculation of the total energy cost in terms of Kilo grams of Calories resulting from the manufacture of any given source of green energy divided by the Kilo grams of Calories expended in its manufacturing. For example a tree is the highest rate of return on energy invested to energy produced: 22 to 1. This is calculated based upon the overall land footprint, water use,...

Energy Balance

...Production of biofuels from raw materials requires energy (for farming, transport and conversion to final product, and the production / application of fertilizers, pesticides, herbicides, and fungicides), and has environmental consequences.[28] The energy balance of a biofuel (sometimes called "Net energy gain" and EROEI) is determined by the amount of energy put into the manufacture of fuel compared to the amount of energy released when it is burned in a vehicle. This varies by feedstock and according to the assumptions used. Biodiesel made from sunflowers may produce only 0.46 times the input rate of fuel energy.[29] Biodiesel made from soybeans may produce 3.2 times the input rate of fossil fuels.[30] This compares to 0.805 for gasoline and 0.843 for diesel made from petroleum.[31] Biofuels may require higher energy input per unit of BTU energy content produced than fossil fuels: petroleum can be pumped out of the ground and processed more efficiently than biofuels can be grown and processed. However, this is not necessarily a reason to use oil instead of biofuels, nor does it have an impact on the environmental benefits provided by a given biofuel. Studies have been done that calculate energy balances for biofuel production. Some of these show large differences depending on the biomass feedstock used and location.[32] To explain one specific example, a June 17, 2006 editorial in the Wall. St. Journal stated, "The most widely cited research on this subject comes from......

Geo Politics

...THE GEOPOLITICS OF OIL Beatrice E. Rangel By 2015, we will need to find, develop and produce a volume of new oil and gas that is equal to eight out of every 10 barrels being produced today … the cost associated … is expected to be considerably more than what the industry is now spending. — Mike Bowlin, CEO, ARCO, 1999 en to 5 to 1. Once the ratio hits 1 to1, oil may be technically extractable but it will be of no use as an energy source. The occurrence of the Oil Peak or Huber’s Peak would call for strong international cooperation to rapidly increase output while curbing demand and investing in alternative energy sources. But what if someone has an alternative plan? SCENARIO A: ALL COME TOGETHER The Middle East finds a path to stability; the Americas actively engage in development of energy resources, as the region holds 12% of the world’s energy reserves. The Americas come together under a development-based approach to Energy Security which reduces the rate of consumption of oil in the United States while creating up- and down-stream job opportunities for the lower income echelons in the countries where significant oil and gas reservoirs are located. Pricing policies entice development of alternative sources. Over a period of 20 years, the energy structure of the Americas becomes the most diversified in the world. Innovation tied to alternative sources of energy boosts development rates in the hemisphere. Democracies become gradually more stable, as the development......

Bio-Fuels: a Debatable Topic

...Bio-fuels: a debatable topic A warm welcome to respected dignitaries and all the participants who are present here today, My name is Swaroop. I’m pursuing M.Sc (ag) extension. I remember that my grandfather used to quote “well done is better than well said” a statement given by Benjamin franklin. Biofuels are they as green as they claim to be? It is well said -yes this fuel has a component of BIO, but is biofuel well doing in meeting all its requirements? Hmm…a debatable topic. As context of my argument, I strongly argue that they are not eco-friendly-when completely relied upon. So what are Biofuels? A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms. Examples of this carbon fixation occur in plants and microalgae. These fuels are made by a biomass conversion (biomass refers to recently living organisms, most often referring to plants or plant-derived materials). This biomass can be converted to convenient energy containing substances in three different ways: thermal, chemical and biochemical conversion. Biofuels have increased in popularity because of rising oil prices and the need for energy security. This biofuels are 1St and 2nd generation. 1st generation conatins ethanol, biodiesel, vegetable oil mostly. The second generation biofuels are mostly made from the lignocellulosic biomass or woody crops, agricultural residues or waste. Taking a brisk turn towards my argument, There are......

Green Energy

...GRE-EN-ERGY The Journey to Sustainability. [pic] By Vijeta Kavethkar Green energy is the need of the hour to sustain our energy requirements. Green energy includes natural energetic processes that can be harnessed with little pollution. Anaerobic digestion, geothermal power, wind power, small-scale hydropower, solar energy, biomass power, tidal power, wave power, and some forms of nuclear power (ones which are able to "burn" nuclear waste through a process known as nuclear transmutation, such as an Integral Fast Reactor, and therefore belong in the "Green Energy" category). Some definitions may also include power derived from the incineration of waste. In this report we have discussed on various dimension of non renewable energy resources and its impact on our environment. It is aptly said that “The Earth has enough to satisfy the Need but not the Greed of the Humans” We have gone beyond boundaries, now if we look back the results of our greed is appalling for us. The below sections show the various examples of non renewable energy sector- Electricity Sector in India The electricity sector in India had an installed capacity of 250.256 was of end July 2014. Out of which considerable amount, approx. 69.12% (172.986 GW), is generated from non-renewable energy source. India became the world's third largest producer of electricity in the year 2013 with 4.8% global share in electricity generation surpassing Japan and Russia. On 31st May 2014, in India, there was......

Renewable Energy Sources

...Chapter 8: Renewable Energy Sources The Sustainability Revolution John C. Ayers "In a sense, the fossil fuels are a one-time gift that lifted us up from subsistence agriculture and should eventually lead us to a future based on renewable resources." Kenneth Deffeyes (2001) "I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that." — Thomas Edison, 1931 We cannot create or destroy energy. We can only capture it. The sun provides either directly or indirectly nearly all of the energy available to us. Plants capture solar energy directly through photosynthesis. Fossil fuels contain the energy of sunlight captured hundreds of millions of years ago. Photovoltaic (PV) cells also capture sunlight energy directly. Other energy sources capture the energy of sunlight indirectly. Heat from the sun powers the flowing air and water. We usually capture the kinetic energy of wind and water by using turbines that transfer the energy to an alternator, an electrical generator that produces alternating current. Geothermal energy is different in that it captures flowing heat energy produced by radioactive decay in the earth’s interior. In this chapter we will see that Wind, Water, and Sun (WWS) energy sources are sustainable because they are renewable, clean, safe, and nearly carbon-free. Although they have low energy densities, meaning that they require large areas of land or water to produce......
