Renewable and non-renewable energy resources and the importance of energy conservation are discussed. Renewable resources include solar, wind, hydroelectric, geothermal, and biofuels which can be replenished. Non-renewable resources like coal, oil and gas are limited and their extraction causes environmental damage. Conservation of energy through efficient use and recycling is emphasized to reduce pollution and delay depletion of non-renewable resources.
this presentation deals with the formation, depletion, conservation of various sources of energy. it also includes the various advantages and disadvantages of the sources.
Natural resources are materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such as fresh water, and air, as well as a living organism such as a fish, or it may exist in an alternate form which must be processed to obtain the resource such as metal ores, oil, and most forms of energy.
Organic-Based Sources; Landfill Methane; Biomass energy; Hydropower ; Flowing water (Hydroelectric); Tidal power (waves and tides); Wave; Geothermal Energy (Geothermal power); Hydrogen Energy; Solar energy: (Energy from sunlight Rapid growing) ; Wind Energy
The presentation is aimed for undergraduate students and covers the details of forest ecosystem, grassland ecosystem, desert ecosystem as well as aquatic ecosystems. It is suitable for compulsory environmental science course at undergraduate level. The content has been simplified for easy understanding of both science as well as humanities students.

PG&E Energy Reduction Plan for Schools http://www.pge.com/rebates/123_reduction_plans/schools/index.html SCHEDULED MAINTENANCE: on units including cleaning burners and air conditioner coils, replacing and cleaning air filters and checking ducts and pipe insulation for damage. LOCKING COVERS: prevents tampering with temperature
PG&E Energy Reduction Plan for Schools http://www.pge.com/rebates/123_reduction_plans/schools/index.html T-8’s and electronic ballasts are more efficient OCCUPANCY SENSORS: shuts off lights when room is not in use REPLACEMENT: install energy star (for HVAC units and roof) when it is time for replacement
