Anyway, one of the solution I believe to deduct dependence on energy.

we know the coal is black and also aware of the darkness behind the light it produces. on the other hand with each passing day our demand and dependence on energy sources is on increase. coal is substantially meeting the power demand of India though its exhaustible.accessibility to electricity is one of the prime parameters of material development. As I experience, human life (pretends/seems) to be indispensable without electricity. Green energy is looked as an alternative. Nuclear energy would have far more environmental consequences. Solar energy still can not be fully relied on. Potential of wind energy is unknown and seems to be costly affair, at least in the beginning. Energy addict/obsessed world even thinking of generating energy from tides. Big hydro projects promoted as green businesses have irreversibly been devastating river ecology. NO TECHNOLOGY AND ENERGY SOURCE CAN BE 100% GREEN. Human civilization has survived for last 800 yrs without electricity. THEN WHY WE FEEL TOO DEPENDENT ON ENERGY. the other gloomy fact what I have seen their is no equal distribution of resources. Cities are supplied huge fraction of total electricity generated. areas beyond NCRs/Metropolitan sink in darkness for most of the time. No mention of remote rural areas. Influential and rich (Govt. and corporate offices) schools, colleges, offices, institutions I BELIEVE WASTE ALMOST 60 % OF ENERGY. the demand of cities is insatiable, the resources are finite. Misuse is so far going as usual/unchecked. Cities(residential complexes, offices) are so insensible built as they require light/bulbs to be on even during day time.
