Sustainable Resources…..
Means of Pure Harvesting with No/minimal
Exploitation ……

2. 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.

3. 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.

4. 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?
