TRANSCRIPT
Presentation Outline
� Country Background� Background of the Energy Sector
– Global trend– Bhutan – Development philosophy – Policies, priorities & targets
� Renewable Energy Sources� Emerging Issues, Challenges & Opportunities� Strategies for Intervention
Background
� Bhutan has always realized the very close linkages between environment, economy and energy use.
� Follows the “middle path”� Preservation of her rich bio-diversity and the
environment has been enshrined in the constitution.
� One of the four pillars of the development philosophy of Gross National Happiness (GNH).
Energy Sector – Bhutan
� Rich Hydropower resources– Developed with assistance from the GoI.
– Major revenue earner for the country
� Primary energy – Bio-mass – 1.2 million m^3 per annum consumption
– 1.9 m^3 per capita (Highest in the world)
� Imports fossil fuel– for heating & transportation
– Nets out the revenue from export of hydropower

Emerging Issues & Challenges (Global)� Non-sustainable
– Conventional Energy Production is not sustainable
– Increasing oil prices
– Oil reserves will be depleted
� Entrenches Poverty– 2 billion people do not have access to modern energy
services
– Entrenches poverty by limiting access to education, economic opportunity, and healthier livelihoods.
Emerging Issues & Challenges (Global)� Gender Equity
– Burden on Women’s time (for collecting fire wood)
– and related health hazards due to fuel wood burning
� Green house Gas Emission & Climate Change
– Fossil fuels and conventional energy increases green house gas emissions and expedites climate change.
Emerging Issues and Challenges (Global)
Why Renewable Energy?
� Utilizes locally available resources
� Reduce the need to import fossil fuels and enhances energy security
� Provides health benefits
� Contributes to rural development as they are modular in nature
� Contributes to achievement of Millennium Development Goals (MDGs)
� Environmentally beneficial as there are no SOXes and Noxes.
� Reduces climate change as there is no Co2 & methane emissions
Emerging Issues and Challenges (Global)
� Renewable energy has emerged as the energy source that is clean, sustainable and one that allows for ownership/partnership development amongst various stakeholders.
– Hydropower
– Solar
– Wind
– Geothermal
– Biomass
Emerging Issues and Challenges� Electricity for All by 2020
� Only 50% of the households have access to electricity (36% for rural households).
� Very high cost of grid extension ($2000.00 per households – need $100.00 million) & deforestation for right of ways.
� 3900 HH identified as off-grid
� To be electrified either through mini-micro or solar PV systems
� High capital cost for renewable technologies – 20-40 cents/unit of solar pv, 3-8 cents for hydro

CRITERIA
TECHNOLOGY OPTIONS FOR OFF-GRID ELECTRIFICATION
Emerging Issues and Challenges� Lack of policy and regulatory framework for promoting
other renewable sources of sustainable energy.
� Lack of capacity at local level.
� Lack of awareness amongst the players on the benefits of using clean energy.
� Lack of resources and financing
� Lack of community participation and sense of ownership
Strategies for Intervention� Policy Intervention
� How to address the question of affordability for the rural poor who needs the real subsidy?
� How to involve local participation and a sense of ownership?
� Investment excise or other tax credits
� Tradable renewable energy certificates
� Energy production payments/tax credits
� Public investment, loans or financing
Intervention
� Technology initiatives
� Strategic public-private partnerships
� Knowledge dissemination, awareness campaign
� Common goals of poverty reduction and empowering of women
� Carbon trading mechanisms such as the CDM (project bundling and sharing of baselines).
Areas : Specific projects
� Solar PV Systems– How to make it affordable
– Share CDM benefits with funding partners
� Hydrogen fuel pilot projects
– Isolated micro hydels are not run to full capacity in Bhutan
– Increase plant load factor (increase efficient utilization)
� Wind Energy
– Wangdue & Punakha
� Energy plantation – bio fuel
– Community forestry
– Use of waste woods
Areas : Specific Projects
� Waste Management – Saw briquettes
– Sewerage bio-gas extraction project
� Promote rural income generation (textiles,handicrafts)
� Improving Access to Education
� Promote rural ICT (computers)
� Promote Adult Education
Hydrogen Economy for Bhutan
� No experiences till date
� But Bhutan has the right environment for hydrogen economy
� Currently have a case study to be funded by UNEP
� Transportation in Thimphu City is the most viable pilot project.
“A simple chemical reaction between hydrogen and oxygen generates energy, which can be used to power a car producing only water, not exhaust fumes. With a new national commitment, our scientists and engineers will overcome obstacles to taking these cars from laboratory to showroom so that the first car driven by a child born today could be powered by hydrogen, and pollution-free. Join me in this important innovation to make our air significantly cleaner, and our country much less dependent on foreign sources of energy."
— President Bush, State of the Union Address, January 28, 2003
CASE STUDY
MAN• MAN demonstrated a 12-meter, low-floor transit bus
powered by a 120 kW 400 V Siemens/KWU PEM fuel cell.
• Hydrogen is stored on the roof of the bus, holding a total volume of 1548 liters, which lasts over 250 km (156 miles).
• The bus was used in public transit service in late 2000 in the cities of Nurenberg and Erlangen.
• MAN demonstrated a second-generation of liquid hydrogen powered buses in 2001 in Berlin, Lisbon and Copenhagen.

Feasibility & Scope in Bhutan
1. We have abundant water resource (raw material for H2 fuel).
2. Bhutan generate electricity without depending on fossil fuels and they are run of river generation.
3. Electricity tariff in Bhutan is one of the cheapest in south East Asia.
4. Environmental protection is one of the pillars of GNH (60% of the land should remain covered with forest for all time to come).
5. There is 100% dependence of fossil fuels on India (All earnings from our hydropower are spent for oil import for transportation).
6. Many Mini/Micro hydels are under utilized in Bhutan (Excess in Chendebji is 40 kW,Sengor will be 50 kW etc).
7. Can be used for cooking and heating (Bhutan’s dependence on fuel wood is 66% )
