#2 Energy Utilization – Need Vs Want

Our body temperature, in normal conditions varies from 36.50C - 37.50C (97.70F – 99.50F) and the condition where our body temperature rises above 380C (100.40F); a minimal increase of 0.50C is considered as fever. Similarly is the case with Earth, the temperature of earth has already raised by 1.10C (after the industrial revolution; 1850), causing fever like condition for earth; obviously with the effects of fever – Global warming just one of that. If there are effects, there must have been some symptoms which we ignored and also there must have been some reasons behind this. Increasing population with few unjustified demands has increased the consumption of high grade energy. This bundled with unmonitored utilization of fossil fuels both directly and indirectly (generation of energy) are few of the causes whose symptoms we simply neglected and as a result of which our media has got a new topic to create interesting pieces of art – “oxygen: a new millennium product” .
This is a fact that the amount of energy which sun can provide us in just two minutes is sufficient to meet needs of human beings for a year, but to harness that energy we will require resources; whose only source is earth and which is very limited. On top of that it is also true that we can’t increase the production of energy from available resources beyond a certain limit. This picture of resources, energy and their utilization, makes efficient usage of energy a mandate for us. International organizations like WWF (World Wide Fund for Nature) after their intensive study on this subject matter has suggested that efficient usage of energy is the only way to meet the needs of energy, with the constraint of 1.5oC rise of temperature (since 1850) by 2050. Developed and few developing countries are already working towards renewable sources of energy. Few are already working upon reducing per capita CO2 emissions of their country.
Energy efficient ways may include upgradation of grid infrastructure, energy efficient manufacturing processes along with improved human activities of saving energy wherever possible. Use of energy efficient lights should be preferred which in long run saves both energy and running cost. Use of naturally cooling constructions should be preferred over glass made constructions as constructions made up of glass capture the solar rays and trap the heat (due to green-house effect). Offices in areas with higher average temperatures can use high energy consuming air conditioners for their purpose. In addition to these, unnecessary usage of energy should also be avoided like continuous usage of air conditions as they not only consume high energy but also devoid us of fresh oxygen leading to health problems. These are just few of the suggestions which can easily be heard being given at different platforms but there are many limitations in implementing such solutions for proper energy utilization. At this point of time, we are not equipped enough either to criticize these suggestions or to suggest alternatives to these. But it is for sure that we are the present users and also we (or someone ours) will be its consume it in future. And we know how to save things at-least which has importance for us.
We believe people will definitely come up with new and creative ideas which can help reduce the energy consumption without changing the whole system and infrastructure. As energy consumption is totally up-to us; each individual and we have to think and decide whether it is our need or want, before demanding for high grade of energy.

#1 Grades of Energy
Grades…everyone must have heard about it but with academic prospect; you will sound rummy to know that energy do have grades….lets know something about this...

According to the ability of conversion of one form of energy into another form, forms of energy are classified as low grade energy (Heat) and high grade energy (Electricity).

Electricity (high grade) can be easily converted to other forms with least losses while conversion of Heat energy (low grade) into useful work or electricity involves much more losses. For example, Fuel run vehicles convert heat energy of fuel into the motion of vehicle (mechanical work); although the efficiency doesn't reach beyond 35%. While the conversion of Heat Energy into Electricity in Thermal Power Plants has maximum efficiency of 38-40%

Converting Heat Energy into Electricity and then converting Electricity into Heat Energy again (Heating purposes) may be effective and can be properly controlled by controlling the amount of current flowing. Suppose 40% (max possible value) of heat energy is converted into Electricity and then again Electricity is converted into Heat Energy with maximum efficiency of 78% (considering transmission losses) giving a total efficiency of 31.2%

Thus using Electrical appliances for general heating purposes like heating water, cooking food (induction cookers), etc. should be avoided as far as possible, so that we could save a bit of energy.
So have a fleck over this and do your part if you feel this worthy.

A type of plastic that can be reheated for an hour and converted back to its original molecular state has been developed by researchers in the US, and being completely recyclable and reusable, petroleum-free, and able to broken down by living organisms, it could change everything about how we consume and reuse plastic.

Water, CO2 and green power are the ingredients for Audi e-diesel
The next step for the project will be industrial scale production

An Audi research facility in Dresden, Germany, has managed to create the first batches of diesel fuel with a net-zero carbon footprint — made from carbon dioxide (CO2), water and renewable energy sources such as wind or solar power.

Germany’s government has welcomed the new technology, created in partnership with a greentech company called Sunfire. Johanna Wanka, Germany’s Federal Minister of Education and Research, even test drove the fuel and called it, “a crucial contribution to climate protection and the efficient use of resources,” according to an Audi press release.

India’s thermal coal imports rise 22% in fiscal 2013-14 at key ports

India’s major state-owned ports handled 17 percent more imported coal in the fiscal year ended March, according to data from the Indian Ports Association (IPA), as its coastal power firms stepped up generation to meet growing demand.
A rush to add power capacity after years of under-investment has forced Indian generators to increase coal imports as state-run domestic monopoly Coal India Ltd (COAL.NS) has struggled to meet demand. Coal-based power generation rose 8 percent to 587.64 billion kilowatt-hours in April-January.
The rising demand from India, Asia’s third-largest economy and the world’s No. 3 coal importer, has helped coal producers in Indonesia and Australia cope with global oversupply and a price slump.
Total coal handled by India’s 12 major ports jumped to 104.7 million tonnes in 2013/14 from 86.7 million a year earlier, the IPA data showed on Friday.
Thermal coal imports through the ports leaped 22 percent to 71.6 million tonnes, while shipments of cooking coal, used in making steel, rose 18.3 percent to 33.1 million tonnes.
India’s major ports handled about two-thirds of coal imports of 137.6 million tonnes in 2012/13. The country has about 176 so-called minor ports.
More than 80 percent of India’s coal output comes from Coal India, which has fallen short of its output target for at least the past seven years due to difficulties in obtaining environmental approvals, lack of railway access and other issues.
India’s total coal production rose by just about 2 million tonnes to 562.4 million in calendar year 2013.

Today there may be rise and fall in prices of sources on which we are dependent, but think over it , fuel sources are depleting. Is there any chances of getting fuel in upcoming years?
And India, It imports 80% of crude fuel. Lets try alternatives. We need engineers for energy, for India...
