But can we replace Coal completely?

Possible, but not yet!

Renewable Energy

Hydroelectric Power

How does a Hydel Plant Work?

Mini-Hydel/ Small Hydro Projects

Hydel Power• Advantages– Clean and Renewable– Availability is not a constraint– Long Lasting

• Disadvantages– Huge Initial Investments required– Potential threat to biodiversity due to reservoir

in the catchment area.– Displacements of communities in case of large

projects

Geothermal Energy

How Geothermal Energy is Harnessed

Assessment• Advantages– Lifetime availability of heat from the Earth– Relatively simple process and easy to set-

up

• Disadvantages– Cannot be set up at all the places as

compared to Solar / Wind or Biomass

• In India, only areas near Himalayas are rich sources of Geothermal energy.

Wind Energy

Energy from Wind

Assessment• Advantages– Clean, easily available– Cost effective on a large scale

• Disadvantages– Availability of Wind power on all days– Efficiency of the turbine and distribution

What is the world up to?

China Announces Massive Solar Projects

‘Solar City’ coming up at Kadiri - AP

20 GW of solar power by 2022 - India

Solar energy covers 2.8% Spain’s electricity demand

Germany meets 1.2% of electricity demand through Solar energy

SELCO – Dr. Harish Hande• Magsaysay Award winner for 2011

• 17 years in operation

• Installed solar lighting systems in over 120,000 households in the rural areas of these states

• Operates on three principles: – The poor can afford sustainable

technologies– The poor can maintain sustainable

technologies – One can run a commercially viable

venture serving the needs of the poor. 

Pay as you go model – Simpa Networks

• The typical payback period is three to five years.

• At that point, the system is unlocked and the consumer uses the electricity as produced for the expected 10-year lifetime of the product.

• The system includes a microcontroller and user interface that uses cloud-based software that ensures that power goes to the home only when it is prepaid.

Assessment• Advantages– Low Risk– Raw Material always available– Reduces waste and reuses it for electricity

generation – double the advantage

• Disadvantage– Educating people on segregation difficult– Technology efficiencies still evolving

Energy Efficiency

Areas of importance

• Industries– Waste heat recovery in factories for reuse– Energy auditing and efficiency programs

• Domestic/Commercial– Energy efficient lighting – Ex: CFLs, LED lights– Air conditioners, refrigerators

• Is there a system in place to rate products as energy efficient?

250 kgs of coal

What’s the difference?

•700 kgs. CO2 pollution avoided •Rs. 1500 saved

What can you do to help solve the problem?

Simple Things To Do

Turn off your computer or the TV when you’re not using it.

Take shorter showers. Heating water uses energy.

Use Natural Lighting/Heating/Cooling wherever

required

Turn off the lights when you leave a room.

Use CFL or LED bulbs.

Simple Things To Do

Offer to help your parents keep the air filters on your AC and maintain your appliances.

Walk short distances instead of

asking for a ride in the car.

Plant a tree. Recycle.
