like how do they work exactly?
and if I wanted to do research in this area which
major would be more or less in that direction?
physics?

If you want to research electric cars, the best field would probably be electrical engineering. If you want to research biofuels, the best field would probably be something related to biology. Perhaps if there%26#039;s a bioengineering major or something like that. 100% 1 Vote 0% 0 Votes 0% 0 Votes
All of living humans %26amp; animal ; inhale oxygen %26amp; exhale carban dioxide.
For the earth’s environment plant inhale carban dioxide %26amp; exhale oxygen.
For Eco. Balance oxygen = carban dioxide
but by burning the energy resources to Generate the Power, release the excess carban dioxide , which is causing the green house effect – due to this Global warming is taking place.
Energy resources are mainly – Conventional %26amp; Non conventional
Conventional such as – Coal , Fossil fuel ( Diesel, Petrol, LPG,CNG, etc.) %26amp; Nuclear etc.
Non conventional - Solar, Wind, Hydro %26amp; Bio diesel etc.
These are mainly for used generating power, using Thermal/Gas/ Nuclear Power Plants. Which is turn used for Domestic use, Industrial %26amp; Commercial purposes such as running Factories %26amp; Transportation, running Agricultural Infrastructures etc. Obliviously with Industrial revolution energy requirement is tremendously increasing. However it leads to releasing of harmful gases and solid waste such as fly ash etc. which is causing Green house effect %26amp; Nuclear plant has risk of harmful radiations which is dangers to human life %26amp; animal kingdom.
Diesel, Petrol, ATF %26amp; Gas is being used in big way for IC%26amp; Jet engines which in turn used for transportation (LMV, LCV, HCV etc.) and Generators etc. Which in turn leading to Global warming, melting of polar ice %26amp; climate change etc.
We are still running plants based on old technologies, warn out %26amp; completed it’s full life may be 40 – 50 years old or more. In India we have seen the fiasco such as Enron Power, a new plant but due to red- tapism couldn’t be operated as per initial agreement %26amp; many more cases. ,
Use of Freon in Air conditioners is also causing to damage to environment. By developing the alternative to Freon %26amp; curbing the use of it.
Where new alternatives are under Research %26amp; development such as Bio diesel using Jetropha seeds (Ratan Jot)etc. so can we plant the Jetropha, this can give us Alternative Fuel for future and stopping the deforestation? and Non conventional sources are still not economical compared to conventional ones except hydro in some cases.
so keeping watch of electricity consumed, Airconditioners and SUV%26#039;s %26amp; no. of Vehicles used by us...
As a social cause it’s the duty of all citizen, Govt. %26amp; Industry to conserve the energy recourse, by not exploiting them and Make our planet Greener %26amp; safer for all.

Saving Planet Earth
Pachauri, R K, 2 June 2008

Climate change and the threat that it poses to human existence is a major concern today. Even the youth have an important role to play to save planet earth
There are many lessons in human history which provide adequate warning about the chaos and destruction that could take place if we remain guilty of myopic indifference to the progressive erosion and decline of nature%26#039;s resources. Much has been written, for instance, about the Maya civilization, which flourished during 250-950 AD, but collapsed largely as a result of serious and prolonged drought. Even earlier, some 4,000 years ago a number of well-known Bronze Age cultures also crumbled extending from the Mediterranean to the Indus Valley, including the civilizations, which had blossomed in Mesopotamia. More recent examples of societies that collapsed or faced chaos on account of depletion or degradation of natural resources include the Khmer Empire in South East Asia, Eastern Island, and several others. Changes in climate have historically determined periods of peace as well as conflict. %26lt;/P%26lt; span%26gt;

Democracy in India has taken firm roots, and earlier misgivings about coalition governments at the Centre have proved largely unjustified, as recent experience has shown. However, in one respect, Indian democracy, with and without coalition politics, has not served the interests of Indian society adequately. In mature democracies, even when there are deep divisions on crucial issues of national interest, opposing parties drop their differences to coalesce around what is perceived as common national interest. One wonders when Indian politics would reach such a stage of maturity.
Greenhouse gases: the developed world
Pachauri, R K, 14 March 2008
Time
Most references to the role of China and India in global mitigation of emissions of greenhouse gases (GHGs) are generally simplistic. The typical argument put forward highlights the fact that these countries would continue increasing their emissions substantially, and, therefore, any efforts at reduction in the developed world would be more than neutralized by increases in the former. The reality is in fact much more complex. It is important to remember that the problem of human induced climate change has been caused by the cumulative emissions of GHGs with concentration levels at 280 parts per million of CO2 in pre-industrial times growing to around 380 parts per million currently. This increase is largely the result of substantial increase in use of fossil fuels in the industrialized world. For this reason, the UN Framework Convention on Climate Change (UNFCCC) included the principle of %26quot;common but differentiated responsibility%26quot;, requiring the developed countries to take the first steps in mitigating emissions of GHGs. However, the record of the developed world has been less than satisfactory in this regard.
National debt vs natural debt
Pachauri, R K, 24 February 2008
The Times of India
The Annual Budget is, undoubtedly, an important exercise in charting out the direction of government revenues and expenditures, but it also meets a much larger objective in signalling priorities for growth and development. Based on an assessment of long term trends the Budget must clearly indicate structural changes that could be brought about through a mix of fiscal measures.
Will the Rs 1 lakh car be an environmental nightmare
Pachauri, R K, 26 December 2007
Business Standard
The recently concluded Conference of the Parties to the UN Framework Convention on Climate Change came up with a final declaration that highlighted the need for %26quot;deep cuts%26quot; in emissions of greenhouse gases to combat the problem of global climate change. The tone and content of the Bali Conference represented a perceptible departure from previous such meetings, in view of the major impacts of climate change assessed in great detail in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (lPCC).
Essentially, the problem of climate change, which is the result of cumulative emissions of greenhouse gases (GHGs) since the beginning of industrialisation, represents only a part of the-much larger problem of unsustainable development. While the world has achieved remarkable success through innovation in providing the means for satisfying the needs of the human race, there are also several distortions which have taken place and grown as a result.

The answers to the perils of climate change will come from intellectual innovation.
The environmental problems facing the world and the depletion of natural resources in different regions of the planet require solutions with a strong intellectual content. A good example of this is the fact that it took the world at least a century-and-a-half to realise the effects of emissions of greenhouse gases, most notably carbon dioxide, and to accept its influence on climate.
This delay was in spite of the fact that scientists as far back as the end of the 19th century highlighted the danger of increasing emissions of carbon dioxide on the earth%26#039;s climate. The reason for this enormous delay lies in a lack of scientific analysis of the problem as well as gaps that existed earlier in the dissemination of information of a scientific nature.
