Non Conventional (Alternative) Energy Source

1) Electrical Energy Management :

Electricity or electric power is produced by generators. The generators are operated by the turbines attached to it. The turbines are rotataed by steam, moving water or wind power to produce electricity.

Conservation of electrical energy:

The following measures can be taken even at home and school to save electricty

1. Use energy efficient applicances to save electricity like Compact Fluorescent Lamps (CFL), Light Emiting Diode (LED) bulbs and other electric equipments.
2. Switch off the lights and fans, television and other electrical appliances when not in use
3. Switch off the mobile phone chargers when not in use
4. Maximise the use of solar radiation.Solar water heating system can be used instead of electric geysers.
5. Minimise the use of air conditioners

2) E-Wastes and its Management?

E-Wastes are generally called as electoinic wastes, Which includes the spoiled, outdated non-repairable electrical and electronic devices. . These waste contain toxic metals like lead, cadmium, chromium and mercury, though also contain iorn, copper, silicon, aluminum and gold which can be recovered.

Sources of e-wastes

• Electronic devices : Computers, laptops, mobile phones, printers, moniters, televisions, DVD players, calculators, toys, sport equipments etc.,

House hold electrial appliances:

• Refrigerators, washing machines, microwave oven mixer, grinder, water heater, etc.,
• Accessories Printing cartridges, batteries and chargers

E-Waste inlcude

• Computer components - 66%
• Telecommunication components 12%
• Electronic Components 5%
• Biomedical Componets 7%
• Other components 6%

3) Environmental impact of e-wastes

Disposal of any kind of electrical and electronic devices without knowldge can become the land fill and water pollutants.

• Electronic equipments contain may hazardous heavy metals such as lead, cadmium that can cuase severs soil ground water pollution
• E-waste dumping yards and the places nearby polluted and cause severe health hazard
