IV. Energy and Water |
| |
Energy used by Delta offices and factories come from purchased electricity and a variety of fossil fuels, depending on availability and needs 6 . The relevant statistics for 2006 are as follows:
1. Purchased Electricity:
In 2006 Delta purchased approximately 337 million KWH of electricity from external sources. The three main factories at Dongguan, Wujiang and Thailand accounted for about 80% of total electricity consumption.
2. Liquefied Petroleum Gas (LPG)
In 2006 Delta's Dongguan and Wujiang factories consumed approximately 36M3 of LPG in total.
3. Natural Gas (NG)
In 2006 Delta consumed around 770,000M3 of NG in total with the Wujiang factory accounting for nearly 60% of all NG use.
4. Diesel
In 2006 Delta's factory facilities (e.g. power generators) consumed around 3,600 KL of diesel, and Dongguan, Wujiang factories accounted for nearly 80% of the consumption. Around 300KL of diesel were used by Delta owned vehicles.
5. Gasoline
In 2006 Delta's factory facilities (e.g. power generators) consumed an insignificant amount of gasoline while around 450KL were used by Delta owned vehicles.
6. Heavy Oil
In 2006 Delta's factory facilities used approximately 36KL of heavy oil with most of it used at the Teningen factory in Germany.
7. Water
In 2006 Delta's total water consumption was around 5,340,000KL. |

Energy Conservation, Recovery and Effects of Solar Power Application |
| |
In addition to the energy/water conservation and resource recovery programs at all Delta factories, the factories at Dongguan (China) and Taoyuan II (Taiwan) use solar water heating systems for their employee dormitories. Solar panels are installed at our Taipei head office, and at our factories in Tainan (Taiwan) and Teningen (Germany). The results from energy/resources conservation, recovery, and solar power applications in 2006 are as follows 7 : |
| |
|
| |
 1. Air-Conditioning Upgrades
Examples include the replacement of old equipment, and the addition of timers or converters. These measures are estimated to save around 1,300,000KWH of electricity a year.
2. Lighting Upgrades
Examples include the replacement of old lighting modules, the use of electronic ballasts, or the addition of timers and sensors. These measures are estimated to save around 3,150,000KWH of electricity a year.
3. Equipment Insulation
Having appropriate insulation not only reduces the ambient temperature around the machinery and makes the work environment more comfortable, but it also reduces the heat emitted, resulting in saving electricity used for air-conditioning. Equipment insulation is estimated to save around 900,000KWH of electricity a year.
 4. Other Electricity-saving Measures
The addition of inverters to elevators and compressors is estimated to save around 590,000KWH of electricity a year.
5. Electricity Recovery
Delta saved an estimated 18,310,000KWH of electricity in 2006 by recovering over 70% of the electricity expended in the product burn-in process.The total benefit from electricity conservation and recovery measures implemented in 2006 was therefore around 24,250,000KWH, or 7.2% of the 337 million KWH actually consumed in 2006.
6. Water conservation measures
In 2006 Delta saved about 154,000 KL of water through water conservation and recovery measures, or around 2.9% of the 5,340,000 KL actually used. The amount recovered was approximately 105,000 KL. These measures included recovery of rainwater and condensation as well as water-saving faucets and toilets. |

 7. Wooden pallet recovery and reuse
In 2006 Delta factories recovered 730 tonnes of wooden pallets, which were converted into wooden products for reuse.
8. Solar power
In 2006, solar water heating systems at the Dongguan (China) and Taoyuan II (Taiwan) factories saved around 700KL in diesel and 7000M3 of natural gas. Solar panels installed at the Taipei head office, and the Tainan (Taiwan) and Teningen factories (Germany) generated 20,100KWH of power during the year.
Through energy saving and recovery measures as well as the use of solar panels and solar water heating systems, we reduced our GHG emissions by around 21,500 tonnes CO2e (carbon dioxide equivalent) a year. |

Greenhouse Gas Emissions, Effluent and Wastes |
| |
In 2006 the main types of waste generated by Delta's offices and production lines included greenhouse gases (GHG), effluent, and solid wastes.
1. Greenhouse Gases: The GHGs specified by the Kyoto Protocol are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs)and sulfur hexafluoride (SF6). Carbon dioxide emissions associated with externally purchased electricity are the main source of GHG emissions from Delta Group. Our current GHG calculations only include externally purchased electricity and fossil fuels used by Delta, giving a total of 265,000 tonnesCO2e。 8 , 9
2. Effluent
