4 (c) Saifur Rahman 4 In 2007, wind capacity reached 93,849 MW (WWEA, 2008). The average annual growth rate in the last 10 years was close to 30% In 2007, photovoltaic (PV) capacity reached 9,100 MW (EPIA, 2008). Solar PV has a ten-year average annual growth rate of 31% In 2006, geothermal capacity reached 9,600 MW (BP, 2008). Worldwide Non-Hydro Renewables

23 (c) Saifur Rahman Nuclear Power Plant 23

24 (c) Saifur Rahman 24 Issues with Nuclear Energy Long term storage of nuclear spent fuel Concern about nuclear proliferation No greenhouse gas (CO2) emissions Cost: US $5 billion to $7 billion for a 1,500 MW plant

25 (c) Saifur Rahman 25 Costs of Renewable Power Technologies

26 (c) Saifur Rahman 26 Cost-Competitiveness of Selected Renewable Power Technologies Source: Renewable Energy: RD&D Priorities, OECD/IEA 2006.

27 (c) Saifur Rahman Jatropha Plant and Seed 27

28 (c) Saifur Rahman 28 Assuming there is no intercropping needed, just jatropha plants, testing shows one can obtain an average of 7.5 kilograms of fruit or 3 kilograms of seeds per tree. Therefore, 6 tons/acre. At a minimum, several hundred acres of land needed for commercial operation. How many tons of Jatropha seeds per acre?

29 (c) Saifur Rahman How many liters of oil per 1,000 acres? With an average ratio conversion of 40% from seeds into Jatropha oil, trees can produce 2,400 tons of Jatropha oil per 1,000 acres. Applying a density rate of 0.9 kg/cm3, it is possible to obtain 2.7 Million liters of oil from 1,000 acres of land per year. 2.646 million liters of biodiesel per 1000 acres 29
