TS Inter 1st Year Environmental Education Study Material 12th Lesson Energy Conservation

Essay Questions

Question 1.
Explain the need for Energy Conservation.
Answer:
The Need for Energy Conservation :
Carbon Footprint :
It is possible to calculate the amount of carbon dioxide and other greenhouse gases that individual or group activities produce. This measure is called the carbon footprint. For instance, approximately one kg of carbon is added to our personal carbon footprint when we drive a car for a distance of about 6km or when we operate a computer for 32 hours. The more the emission of carbon, the more the environment gets polluted. Today there is greater awareness about the need to reduce our carbon footprint and thereby protect the environment. Energy conservation is one of the methods to reduce damage to the environment.

Energy conservation refers to the effort made to reduce the consumption of energy by using less of an energy service. Energy conservation differs from efficient energy use, which refers to using less energy for a constant service. For example, driving less is an example of energy conservation. Driving the same amount with a higher mileage vehicle is an example of energy efficiency. Energy conservation and efficiency are both energy reduction techniques. Energy conservation leads to enhanced environmental quality and greater personal savings. Energy Conservation is one of the most important steps towards building a sustainable energy system. If a country is self-sufficient in energy, it need not bow down to the pressure tactics of other countries to meet its energy needs.

While the government can formulate policies and frame laws which ensure energy conservation, there are many small steps that can be taken by individuals to conserve energy. Given below are energy conservation techniques that you can follow in your daily life to reduce your overall carbon footprint and save money in the long run. Long term solutions for energy conservation too are listed.

I. Energy conservation at the individual level :
1. Install CFL and LED lights :
Incandescent bulbs should be replaced with CFL (compact fluorescent lamp) or LED (light emitting diode) bulbs. CFL and LED bulbs cost more upfront but last 12 times longer than incandescent bulbs. CFL and LED bulbs save not only energy but also money over a period of time.

2. Optimise the Room Temperature :
Heaters, coolers and air conditioners are commonly used to regulate the temperature indoors. The more the difference between indoor and outdoor temperature, the more the energy consumed to maintain room temperature. The temperature indoors should be kept as close as possible to the outside temperature for energy conservation. Programmable thermostats can be used for this purpose.

3. Insulate your house :
Insulation gives cool air in summer and winter.

Energy-Saving Tips

  1. Replace light bulbs with CFLs
  2. Unplug electronics when not in use
  3. Adjust your thermostat 5* higher
  4. Load up dishwasher until full
  5. Keep cool with ceiling fans
  6. Power down your computer
  7. Wash clothes in cold water

4. Maximize the use of natural light :
Switch Off lights during day time will reduce current bill.

5. Get an Energy Audit Done :
Take advice from expert energy saver to save current bill.

6. Use Energy Efficient Appliances :
Buy star products to save electricity bill.

Concept
The Green Building concept is gaining importance in various countries including India. These are building that ensure that were is minized that every stage including the construction and operation of the building resulting low costs, according to experts in the technology.

7. Drive Less, Walk More and Carpool :
Sharing Transport Vehicles will save energy.

8. Switch Off Appliances when Not in Use :
Save energy by switching off computer, Electric devices etc., when not in use.

9. Grow trees :
Plant more trees to provide cool air

II. Long term solutions for energy conservation :
1. Education :
Educate the people to create awareness on Energy Saving.

2. Availability of Eco friendly Alternatives :
Eco friendly alternatives should be available to reduce the carbon footprint. Energy saving bulbs like LED, CFL should be supplied as subsidized for consumers.

3. Zero Energy Balance Construction :
New methods are being used to construct buildings in such a way that there is minimum emission of green house gases.

4. Alternative Sources of Energy :
The use of alternative sources like solar energy and wind energy, is a key energy conservation technique.

5. Cap and Trade Agreements :
There are agreement between Government and Person concerned who establish industry. He will record minimum pollutant limits.

6. Reduced Demand :
With the emergence of specific economy and social conditions Vehicles and Hydride Cars, including in India – the demand has increased and reduce manifold.

7. Research & Development :
Continued funding of research should be done to solve the problem of Fuel.
