Green technology addresses climate change and environmental sustainability.
Use energy most efficiently.
Transform our transportation system.
Producing renewable energy.
Stabilizing the climate require changes in many sector of economy.
CLIMATE CHANGE
Reliance on fossil fuels for energy is a central part of the problem.
Reducing their dominance in the global energy system will be key for climate stability.
Carbon dioxide emission from fossil fuels will have to be cut by 85% below current level by 2050 to prevent catastrophic climate change
This require major changes in the worlds energy infrastructure and more efficient use of energy.
Require mobilizing substantial resources which in turn will depend on major policy changes that overcome subsidies that prop up the current energy system.
Transformation in energy has been a relatively static business characterized by slow incremental change.
INDIAN SCENARIO
Changes in national and state policies have created a large domestic manufacturing basis for renewable energy systems and products.
Annual turnover of the renewable energy industry including the power generating technologies for wind, solar and biomass has reached a level of Rs.500 Billion.
LIGHT POLLUTION CONTROL
LED’S BEING A POINT LIGHT SOURCE ,CAN BE
SUITABLY CONTROLLED WITH A LENS TO ILLUMINATE DESIRED AREA .
IDEAL FOR CONTROLLING LIGHT POLLUTION
REDUCTION OF LIGHT POLLUTION IS ACHIEVED BY
MINIMIZING TRESPASS FROM BUILDING AND SITE
AND REDUCTION OF SKY GLOW TO INCREASE
NIGHT SKY ACCESS.
