2. Rural Energy Systems Highly Sustainable Model for Naturally Sustainable Resources….. Means of Pure Harvesting with No/minimal Exploitation …… P M V Subbarao Professor Mechanical Engineering Department

3. What is A Natural Resource? A highly distributed native boon. Any child of nature, which contains more (?) than what it required for itself. All this excess is meant for other children of nature. This excess it called fertility. Land has a fertility to grow plant and crops. Trees and plants have lushness to generate more food. Many animals possess fecundity to serve others. Rivers have abundance called Reverine Bounty. The ultimate boon almost uniformly available on this globe : Solar Energy.

4. Harvesting : Sustainable Utilization Some thing not an exploitation. Use of a natural resource should not spoil that resource or other resources of nature. Plucking of a fruit from a tree without spoiling the tree. This is called harvesting. The size of energy production system should be completely based on harvesting a resource. Harvesting of Natural Resources is only is possible through a Pico Energy System.

5. The Size & Issue of Sizing A Power Plant : > 100 MW. A Small Power Plant: 5 MW to 20 MW. A Mini Power Plant: 500 kW to 2 MW. A Micro Power Plant: 50 kW to 200 kW. A Pico Power Plant: < 30 kW. –Rural Energy Systems are Pico Plants. –No Standard technologies. –Highly customized Designs. –Low Profit Margins. Why Pico?
