Emission mitigation from implementation of minimum energy performance standard (MEPS) for TVs in Malaysia

Abstract

This paper assesses the potential mitigation of emissions by implementing minimum energy performance standard (MEPS) for residential TVs in Malaysia. The ownership of TVs in Malaysian household has increased rapidly over the past three decades. The number has increased from 186,036 units in 1970 to 2,741,640 units in 1991 and is predicted to be about 7,292,931 units in the year 2015. To reduce energy consumption in the residential sector, the Department of Electricity and Gas Supply is considering implementing MEPS for TVs in the coming year. In this study the potential reduction of emissions as a result of implementing MEPS is calculated. It has been estimated that the implementation of MEPS for residential TVs would reduce approximately 57,837,060 kg of CO_2, 351,114 kg of SO_2, 164,609 kg of NO _x and 34,777 kg of CO emissions during the standard period of 10 years. These emissions reduction will eventually enable us to control environmental impacts such as global warming.

Appendix 1. Sample calculations for the year 2005

$$ Sh_{i} = {\left( {5,185,191 - 4,991,025} \right)} + 3,716,410 = 3,910,576\;units $$

(16)

$$ BEC = \frac{{{\left( {75\;{\text{W}} \times 8\;{\text{h/day}} \times 365\;{\text{days}}} \right)} + {\left( {4.5\;{\text{W}} \times 4\;{\text{h/day}} \times 365\;{\text{days}}} \right)}}} {{1,000}} = 225.570\;{\text{kWh}} $$

(17)

$$ SEC = \frac{{{\left( {75 \times 8 \times 365} \right)} \times {\left( {1 - 0.01} \right)} + {\left( {4.5 \times 4 \times 365} \right)} \times {\left( {1 - 0.01} \right)}}} {{1,000}} = 223.314\;kWh $$

(18)

$$ UES_{s} = 225.570 - 223.314 = 2.256\;kWh $$

(19)

$$ SF_{i} = 1 - {\left[ {2005 - 2005} \right]} \times \frac{{1\% }} {{10\% }} = 1 $$

(20)

$$ UES_{i} = 1 \times 2.256 = 2.256\;kWh $$

(21)

$$ AS_{i} = 3,910,576 + 0 = 3,910,576\;units $$

(22)

$$ ES_{i} = {\left( {3,910,576} \right)} \times {\left( {2.256} \right)} \times {\left( 1 \right)} = 8,822,260\;kWh $$

(23)

$$ ER^{{{\text{CO}}_{{\text{2}}} }}_{i} = 8,822,260{\left[ {{\left( {15.50\% \times 1.18} \right)} + {\left( {3.25\% \times 0.85} \right)} + {\left( {58.75\% \times 0.53} \right)}} \right]} = 4,604,338\;{\text{kg}} $$

(24)

$$ ER^{{{\text{SO}}_{{\text{2}}} }}_{i} = 8,822,260{\left[ {{\left( {15.50\% \times 0.0139} \right)} + {\left( {3.25\% \times 0.0164} \right)} + {\left( {58.75\% \times 0.0005} \right)}} \right]} = 26,301\;{\text{kg}} $$

(25)

$$ ER^{{{\text{NO}}_{x} }}_{i} = 8,822,260{\left[ {{\left( {15.50\% \times 0.0052} \right)} + {\left( {3.25\% \times 0.0025} \right)} + {\left( {58.75\% \times 0.0009} \right)}} \right]} = 12,492\;{\text{kg}} $$
