Catch wind at night to charge battery on rooftop: Expert

Thiruvananthapuram, June 16 - A renewable energy expert
has said that small aero-generators running at minimum
speeds could be installed along with rooftop solar plants
proposed in the State.
Solar power can charge the battery during the day while
the wind can take over in night, said A.Mohammed Hussain,
director of Chennai-based Centre for Wind Energy
Technology.
NATIONAL GRID
He said this while addressing a workshop on ‘Energy and
environment – challenges and solutions’ organised here by
Kerala State Industrial Development Corporation.
K.M. Chandrasekhar, vice-chairman, State Planning Board,
said that the country should have a strong national grid
that takes care of assured supplies of power.
The national grid could link varied sources of and enable
evacuation of power from surplus to deficit regions, he
said.
It was also important to find a right balance between
energy and environment as both were closely linked
critical areas, Chandrasekhar added.
NOT ENOUGH
Not enough resources were being pumped in to keep Indian
cities clean, according to Kala Seetharam Sridhar, head,
public policy research, Public Affairs Centre, Bangalore.
She said this while giving an economic perspective to
solid waste management in her presentation at the
workshop.
The World Bank recommended an expenditure of 0.5 per cent
of gross national product for solid waste management but
the spending in India was far below, she said.
Open dumping is the least expensive option at an
estimated $3 to $10 per tonne, whereas waste to energy
incineration costs $40 to $100.
This explains why most Indian cities are resorting to
open dumping, Sridhar said.
COMPSTABLE ORGANICS
Kerala had necessary preconditions such as high literacy
and high per capita income that are integral for good
solid waste management practices.
Compostable organics in some cities surveyed in the State
contributed to an average 72 per cent of the total waste,
which was much larger than other Indian cities.
She called for better coordination between departments to
find a common strategy to deal with the problem.
Harnessing information revolution, segregation of waste
at source and conversion of organic waste into energy
could be other options.
“It is also important to recognise and integrate the role
of urban poor such as rag pickers in keeping our cities
and towns clean,” she added.
