International Energy Agency’s (IEA) suggested threshold electricity
consumption is 250 kWh and 500 kWh per household per year for rural and
urban households respectively1.
In rural areas, 250 kWh can power a floor fan, a mobile phone and two
light bulbs. In urban areas, consumption might include a small
refrigerator, a second mobile phone and a small television.
However, according to World Bank data, no country in
the world with an income per capita above $10,000 has electricity
consumption below 3,880 kWh/person/year – nearly eight times the IEA
target for a whole urban household2!
According to IEA statistics, India’s per capita
consumption of electricity in 2012 was 760 kWh (US stood at 12,950 kWh,
China at 3480 kWh and Brazil 2150 kWh). While this is above IEA
thresholds (on average), it is far below what it should be for Indians
to enjoy the lifestyle the West takes for granted. But what would it
mean for climate change if India provides 3880 kWh/person/year – a
fivefold increase over the present?
Electricity and emissions
Emissions associated with electricity generation may
be estimated as the product of 2 variables:
• carbon intensity of electricity generation measured
in kg CO2 per kWh of electricity
generated
• total electricity generated measured in kWh (units)
India’s carbon intensity of electricity generation
(0.7 to 0.9 kg CO2/kWh) is one of the
highest in the world, as the production mix is dominated by coal. In
comparison, in Norway, Iceland and Paraguay, emissions are less than
0.02 kg CO2/kWh3.
Due to the high carbon intensity, India’s total emissions are also high
despite low levels of electricity generation, as demonstrated in the
graph.
Let us explore emissions implications of bridging the
gap between current per capita consumption of 760 kWh and desired 3880
kWh. Doing so in the Business As Usual scenario (increasing production
capacity without changing the proportions of each fuel in the production
mix) will entail additional carbon emissions of over 2 metric tonnes per
capita. This would almost double current emissions of 2.44 metric tonnes
per capita4. If the
proportion of low-carbon sources (solar, wind, nuclear, etc.) in the
production mix were increased, such that low-carbon sources account for
50% of the production mix and coal’s proportion is reduced from the
current 60% to 40%, the carbon intensity of electricity generation
decreases, and therefore so does the quantity of emissions. In this
scenario, additional emissions would amount to approximately 1.5 metric
tonnes per capita: a 30% improvement over scenario 1, but still a 60%
increase over current carbon emissions per capita (Source: Author).
The numbers may be alarming, but they should be seen
in perspective. In the high-carbon scenario, India’s per capita carbon
emissions would rise to 4.5 to 5 metric tonnes per capita. This is quite
small compared to US’s 19.86 metric tonnes, China’s 8.13 metric tonnes
and EU’s 8.77 metric tonnes at present5.
Due to large population, overall emissions in India are likely to be
higher. In fact, India’s total emissions may become highest in the
world. However, from a social justice perspective, the per capita
numbers are equally important. The IEA’s threshold energy consumption is
abysmally low compared to the developed-world consumption levels.
Fortunately, there are significant gains possible in carbon intensity of
electricity production, which may alleviate the problem to an extent.
