Prepare on speech the world energy conservation day
Answers
Explanation:
World Energy Conservation Day is celebrated on 14th December globally to highlight the importance of energy consumption and its use in our day-to-day life, its scarcity and its impact on sustainability of global eco systems. It focuses our concentration on significant issues facing the future of mankind with respect to energy. This Day serves to spell a sense of urgency on the issues involved.
It is a day for building up awareness regarding
- Need for energy conservation,
- Energy efficiency
- Frugality in energy use.
Energy use is a major source of global warming, which has the potential of making the earth uninhabitable. As we all aware of the threatening fact that reserves of all conventional forms of energy are fast depleting. Every day the human population across the world uses energy for leading a civilized life. These resources are critical input of human development which comprises providing adequate food, shelter, clothing, water, sanitation, medication, schooling, transportation, industrial applications, access to information, etc. In short, energy affects all facets of activities related to everyday and modern life. Per capita energy consumption is often considered an important indicator of development. As people and nation’s progress, consumption of energy will increase.
Conventional sources of energy:
The most important and popularly known sources of energy are
- Coal,
- Petroleum
- Products
- Nuclear energy
These resources of commercial energy are available only in limited quantities. At current reserve to production ratio, oil is expected to last around 45 years, gas around 65 years, coal around 200 years. (Source: BP Statistical Review of world Energy, 2010). The above timelines demonstrate the need for urgent world action for funding research and development of alternate energy sources, which are affordable, available in adequate quantity and perennial in nature. The need for energy conservation and economical use of energy arises basically because of its features of universal usage, fast depleting resource and impact on climate change.
Need of Energy management:
'It means saving energy in businesses, public-sector/government organizations, and homes. Much of the importance of energy saving stems from the global need to saveenergy but, if you’re a homeowner looking to save energy, don’t be put off by the fact that this article focuses more on non-residential buildings. Most of the principles that apply to businesses and other organizations are also applicable to homes. We must serve us by energy saving at homes.
- Save Energy in the Home by Air Drying Your Laundry
- Run your heating for just one hour less every day
- Keep the air flow vents on your electric heaters clear of obstructions
- Turn down your thermostat by one degree and you could save up to L65 a year
- When buying new appliances, be sure to purchase energy-efficient ENERGYSTAR labeled models.
- Use compact fluorescent lamps. You can lower your lighting bill by converting to energy-efficient low-wattage compact fluorescent lighting and fixtures.
As exhaustion of fossil fuels, which supply three quarters of this energy, is not far off, and no other energy source is abundant and cheap enough to take their place. Human beings like to believe they are in control of their destiny, but when the history of life on Earth is seen in perspective, the evolution of Homo sapiens is merely a transient episode that acts to redress the planet’s energy balance.
Some false hopes about alternate energy resources:
Today’s second-most-important source of energy, after fossil fuels, is biomass conversion. But all the world’s wood fires, all the grain alcohol added to gasoline, and all the agricultural wastes burned as fuel only provide 15% of the world’s energy. And biomass conversion has little growth potential, since it competes for fertile land with food crops and timber.
Hydropower furnishes about 5.5% of the energy currently consumed. Its potential may be as much as five times greater but this is not sufficient to take over from fossil fuels, and huge dams would submerge rich agricultural soils.
Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. This can be achieved either by using energy more efficiently (using less energy for a constant service) or by reducing the amount of service used (for example, by driving less). Energy conservation is a part of the concept of Eco-sufficiency
1. Make sure your air conditioning and heating units are ENERGY STAR models.
2. Set a non-ENERGY STAR air conditioning unit to “Quiet Guard” or “Power Save” mode.
3. Get a programmable thermostat that will automatically turn your AC and heater on or off to save on energy.
4. Always keep windows and doors tightly shut when running the AC or heater.
5. If you have central AC, close the air vents in unused rooms to avoid cooling or heating unused spaces.
6. Turn off kitchen or bath exhaust fans as soon as possible.
7. Use ceiling fans to cool a room instead of turning on the AC.
