India energy supplies :
Case study :Jatropha as a bio fuel in
India
Key idea on WJEC specification
• 1.6 Key question : What are the
environmental challenges and solutions
facing India?
• The causes and consequences of the need
for energy supplies
Energy supplies India a perspective
• In 2006, India was the sixth largest oil consumer in the world.
• India lacks sufficient domestic energy resources and must
import much of its growing energy requirements.
Jatropha as a bio fuel in India
• In 2009 BP announced it is
investing almost £32m in a
jatropha joint venture with
UK bio fuels firm D1 Oils.
• Once dried out and crushed,
the seeds yield oil which can
be burned in almost any
diesel engine - with no
modification.
What are its advantages?
• 1.Impact on climate change :Bio fuel plants like jatropha
absorb carbon-dioxide while they are growing, effectively
cancelling out the carbon dioxide they release when they
burn.
• 2. They could allow developing countries like India to be
more self-sufficient rather than depending on oil and gas
imports.
• 3. Jatropha can grow in poor soils and needs very little
water to survive.
What are the issues with bio fuels and sustainability?
• Subsistence farming growing food to eat - is still a
widespread activity, jatropha
could replace much-needed
food crops, turning India into
a monoculture.
• The UN says basic food
prices for poor countries are
being pushed up by
competition for land from bio
fuels.
• A report from the charity Grain
amplifies recent warnings from the
UN's Food and Agriculture Organization
(FAO) that some bio fuels produce
hardly any carbon savings at all.
• The Grain report says its research
shows how governments and bio fuels
firms in developing countries are
collaborating to push indigenous
people and peasant communities off
their land.
