LET THERE BE LIGHT-BUT NOT TOO MUCH

Solutions, for example, that are based on Digital Addressable Lighting Interface (DALI). The wireless application reduces wiring between operating elements & lighting control. Up to 64 devices that control lighting groups may be flexibly positioned via a single bifilar cable. Expenditures for planning & modernization are minimized. Day light dependent lighting control systems, that use sensors to record changes in lighting & balance the system energy-efficiency, have been available for some time.
Equally established is the use of energy saving lighting system for street lighting. Osram played a successful part in projects where quicksilver steam lamps & upto 55% in energy was saved per lamp. Brickmann: “we have been able to successfully apply our expertise in many municipal energy-saving projects, for example with US Air Force properties in Germany”.

                  If the Sun is shining outside, a room needs less artificial light than on a gloomy day in the fall. If a workplace is not occupied, office lights can be shut off. “Intel-ligent lighting systems integrate intensity sensors & the interface to electric blinds to ensure a balanced interplay in buildings”, says Ullrich Brickmann, Head of marketing, solutions for energy efficiency Siemens building Technologies. The company uses lighting agents from Osram. This lighting specialist has developed technologies for lighting solutions dependent on daylight.

LET THERE BE LIGHT-BUT NOT TOO MUCH

Edition-1
Artificial light needs electricity & lots of it. In buildings without other technically complex installations like schools, kindergartens, or administration offices, lighting & computers account for about 30% of energy consumption. Effective lighting concepts are thus an important part of energy saving performance contracting. Within this concept, Siemens makes use of synergies within the company & can intelligently optimize the entire system.
A lot more is at stake than automically switching off the lights when they are not needed. Lighting agents & illuminants play an essential role as well. Moreover, the right lighting system to adapt brightness according to usage & environmental surroundings.

WATER, WATER EVERYWHERE

Edition-2
An ongoing study being conducted by the Central Ground Water Board in Gujarat has found that the water table in the state, which was depleting at a frightening pace until about seven years ago, is now going up, with the decade-long check dam drive being one of the main contribution factors. Another factor that has led to rise in the ground water table is the filling given by the Modi government to drip irrigation. Modi’s mantra has been:’ if you want to save future generations then recharge ground water instead of mercilessly exploiting it.” People are listening, especially farmers.

It can go down as one of the wonders of independent India. The 1 lakh check dams that the Gujarat government, local people & NGOs have built in the past decade as part of a statewide campaign launched by the then chief minister Keshubhai Patel in 1999, & then taken to a missionary level by his successor, Narendra Modi, has created something that gives hope to the entire country. (Check dams are barriers built on shallow rivers, or even streams, for water harvesting). The message: If Gujarat can bring up the once depleting water table in the state, the rest of India, which is struggling to cope with water crisis-created by overuse of water & the lack of water table recharge measure-can also do it.

WEST BENGAL GOV., (INDIA) FAIL TO GIVE ITS PEOPLE SAFE DRINKING WATER

After a long 28 years pass away, still the West Bengal Gov. did not able to prepare the Arsenic area affected map. Due to this, it is practically impossible to take any workable project to reduce the Arsenic pollution.

                        Today, ground water contamination with Arsenic is not only serious problem in India but also to world. Because groundwater is natural & safest source for drinking water (compare to other source), heavy metal Arsenic makes this water undrinkable to us.

                        At present in West Bengal, 17,000 villages of 79 blocks are under Arsenic contamination. It does not end here. New area is affected by passing time & until recognization process speed up. The Arsenic problem in West Bengal creates Cataclysm. When the eyes of West Bengal Gov. will open? God knows until, the work of Institution like BESU are appreciatable. However, this work is not for Institutional or NGO’s, it totally depends on Gov. to give its people safe drinking water.

                   One other way to ensure India is not too drunk on oil & coal is to promote clean power. Wind & solar, for instance. Apart from tax sops & incentives for generation, the government plans what are called renewable-energy certificates. Under this, renewable energy target for utilities & big power consumers will be set. Each megawatt-hour will stand for one renewable energy certificate. Again, those exceeding targets can sell to the laggards. This too is a market mechanism.

                       The developed world has offered emission reductions in varying proportions, from the more ambitious EU & Japan to the politically practical & modest US. India & China & similar developing countries would not announce absolute emissions. They have settled for carbon intensity reductions, or emissions per unit of economic output. In a growing economy, this would not lead to a cut in absolute emissions.

                         Meanwhile, the developed world, already more aware in environmental matters, is mulling things like green procurement. This will enable it to reject products made in an ecologically unsustainable manner. It is also pouring money into clean-tech research. The current emission-reduction pledges off all countries, however, are not seen by scientists to be good enough to stop a dangerous increase in temperatures. The arguments continue.

What polluters such as China & India have done is have national road maps to attack climate change. India has called the National Action Plan on Climate Change. It has eight components, including measures to boost solar energy, energy efficiency, ensure sustainable habitats & agriculture, optimize water use, sustain the Himalayan ecosystem, promote afforestation, and build knowledge in climate modeling.
This is a source of regulatory risks & opportunities. Its energy efficiency component, for instance, will be targeted at the industrial sector. Those like power, cement, fertilized, iron & steel plants. The idea is to set energy efficiency standards for each sector. Those bettering standards can sell energy-efficiency credits or energy-saving certificates to the laggards, as part of a market mechanism. The other potion for laggards is to be penalized.

Start cutting emissions right away, scientists have been warning nearly two-and-one-decades. In addition, someone like Al Gore, former US Vice-President, drummed up awareness for the cause through his award winning film An Inconvenient Truth. World governments, in principle, agree with scientists. However, the worldwide framework to tackle climate change still eludes them.
The US, a big polluter, opted out of the first such effort, the Kyoto Protocol, set to expire in 2012. It was in this Protocol that the clean Development Mechanism made its debut. Under this, developed countries had either to cut down the emissions or buy carbon credits from greenhouse gas-reducing projects in developing countries. Corporate in China and India generated the majority of credits. Under Kyoto, developing countries did not need to make emission cuts, & THIS THE BONE OF CONTENTION NOW. This is sensitive because emission reduction is seen as economically suicide.

     Cut Trees, Burn Coal. Burn some other fossil fuel too, let us say oil. Do it for 200 years. In addition, result you have climate change on your hands. So well human beings that we are finding it difficult to change, even if our very survival hinges on it, have perfected this recipe. Climate change, by the way, is how the earth’s climate is getting impacted by carbon-di-oxide emissions & other green house gases, courtesy the cutting & burning. It, of course, means a hotter plant. However, it also means changes in rainfall patterns, ocean currents & melting of glaciers. It would not make for a livable planet. The Maldives, for instance, is seen sinking. Yet, skeptics still call climate change fiction.
