WHAT IF!! For every 1 degree rise in global average temperature the impact on the planet gets worse!

Science behind Green


à There is a vast difference between climate and weather. Climate is an average of long term weather pattern experienced in that particular area.

Climate change you say….huh?

à Climate change can occur due to natural causes. But today, climate change refers to the change in climate due to the human activities.

Greenhouse effect…is it?

à The atmosphere of the earth is made up of mixture of gases. Some of these gases allow warm rays of the sun to penetrate inside the atmosphere, and make the earth warm, but do not allow them to escape back. This is called greenhouse effect.

Carbon cycle….new cycle?

à The natural cycle of the earth where carbon is added to the atmosphere by various means such as fires, carbon di oxide exhaled by human beings etc. and the same carbon is removed from the atmosphere by photosynthesis by plants, absorption by the oceans etc. is called carbon cycle.

à This cycle would have remained steady if only humans did not intervene. Due to burning of fossil fuels and disruption of greenery, us human beings have intervened in this natural cycle and made it unbalanced.

Global Warming……is the globe warming?

à The average increase in earth’s temperature caused by rapid increase in the greenhouse effect due to human activity is called global warming.

Recharge Gizmos with Sun Energy!

A new kind of solar cell that copies Mother Nature’s way of converting sunlight to energy is the new idea for going green in the electronics market.

This new cell uses a new kind of photosensitive dye to produce energy, the same way plants perform photosynthesis.

These dye sensitive cells will be used to power a wide range of electronic devices ranging from e-book readers to cell phones.

The photosensitive cell will work in full throttle in bright sunlight and also work in inside ambient light such as bulbs and tube lights.

The solar cells have 11 cells each and take about six-eight hours to fully charge the device in bright sunlight, but takes a little more time indoors.

Tips for Green Residential Complexes

· Water Recycling

- A small recycling plant can be devised so that all the grey water coming out from residents can be recycled and reused.

· Rainwater Harvesting

- Tanks on residential buildings or wherever possible should be constructed and used for harvesting of rainwater for future use.

· Garbage disposal

- All waste coming out from residents should be segregated into wet and dry wastes. As far as possible wets wastes should be recycled and reused as manure or compost.

· Planting Trees

- Trees should be planted in and around residential complexes. They not only spread greenery and generate fresh oxygen but they also keep the surrounding air cool.

· Environment friendly construction practices should be adopted.

· Power

- Energy efficient lighting systems should be used in flats. People should be made aware of the general tips they could adopt for saving electricity in their homes.

- As far as possible encourage use of natural day light in common areas of the building.

Case Study – China Builds Low Carbon City

14th May 2010

Turpan, a small town in Xinjiang province in china is going to experience its first environment friendly city.
The model city will be spread across 8.8Sq.Km. Solar energy and wind energy will be utilized to power the city.

For cooling and heating purposes, geothermal energy will be utilized. For public transport, the city will have zero pollutant electrical buses and taxis. The use of private cars will be minimized to least number possible.

Green Lifestyle

The idea of being conservative and environment friendly now has to become more than just an idea.

Many organizations in the professional arena are doing the best they can but this is not it. Smaller changes in the form of individual lifestyle changes in the personal arena can also help and contribute towards sustainability.

In summary we should look in conserving the energy that comes inside the house as also the one which goes outside as waste.

Generally, a home comprises of four main compartments – the bed, the hall, the kitchen and washrooms. These are the places one should look into.

The ideal way to save energy is to use electrical appliances in these four compartments efficiently.

For instance, check whether your ceiling fan has proper blades to spread enough air around the room. Now a days many electrical appliances come with a rating system which tells the consumer how energy efficient that particular appliance is.

Providing consumers with this type of information spreads eco-consciousness among them and they also start thinking the green way.

Another area where individual people can contribute is proper waste management in and around their own locality. Figures say that almost 70% of all household waste is wet waste.

The idea is that individuals now need to assess their own actions and how they impact the environment. This small idea of change in lifestyle can impact the environment to a large extent making it cleaner and greener.

Denmark generates Electricity from Thrash

The people of Denmark can now live clean and happily as their new power plant generates electricity from thousands of tons of household garbage and waste from industries.

This new plant is by far more cleaner than conventional incinerators which is filled with dozens of filters to filter out all pollutants and toxins coming out of it.

Because of this power plant, their energy cost as well as fuel costs have reduced to a greater extent. Not only this, but they have benefited the environment by diminishing the use of landfills and cutting carbon di oxide emissions. 

With all these innovations, Denmark now regards garbage as a clean alternative fuel rather than a smelling environmental hazard.
