Promoting the use of solar energy
As indicated in our last newsletter, we have been
promoting the use of solar-powered lighting devices. We
are currently involved in the installation of
solar-powered street-lamps with the additional advantage
of newly-designed fixtures consisting of light emitting
diodes (LEDs). While the use of solar energy results in
direct conservation of electricity, the LED-based
devices also result in energy saving, as they are more
efficacious: a 27 W fixture emits as much light as (i.e.
luminous equivalent of) a 40 W fluorescent tube.
Further, the relatively long durability of LEDs, as
compared with the fluorescent options, reduces the cost
and effort of replacement. Installation is taking place
for street-lighting at a new residential colony. More
details will be provided in the following newsletter.
Energy for Sustainable Development (ESD),
the journal of the International Energy Initiative
XII, No.4 of IEI’s
quarterly journal Energy for Sustainable Development
(ESD) has been
published this month. It is a Special Issue on
access to clean energy for the urban and peri-urban poor.
While better (cleaner and more efficient) forms of
energy are more easily available in urban areas, these
are often not “accessible” to the
economically-disadvantaged because of their inability to
pay the prices of higher quality services and/or their
insecure housing. The articles in this issue are
primarily based on case-studies of poor areas of
specific cities: Bangkok and Khon Kaen (Thailand), Cape
Town (South Africa), Dakar (Sénégal), Nairobi (Kenya),
Delhi (India), and Buenos Aires (Argentina). While the
circumstances vary from city to city, certain policy
recommendations appear to be widespread, the most
important of which is legalising housing. Another
policy would be to subsidise the initial cost of
electricity, LPG, or natural gas connection, rather than
the energy use, as it would also encourage
conservation. Further, subsidies should be targeted at
poorer households rather than uniformly applied to all
households. The studies were commissioned by the Global
Network on Energy for Sustainable Development (GNESD).
