Sharp's Energy-Creating and Energy-Saving Products Equalize Sharp's Greenhouse Gas Emissions

Sharp aims to reduce greenhouse gas emissions from its worldwide business activities to such an extent that, by fiscal 2010, the quantity of greenhouse gases emitted that year will equal the quantity of greenhouse gases avoided that same year through customer use of both Sharp solar cells sold during the preceding 20 years and of Sharp energy-saving products.



By reducing as much as possible the amount of greenhouse gases emitted as a result of Sharp's worldwide business activities, while at the same time, significantly increasing the magnitude of reductions in greenhouse gas emissions through customer use of Sharp energy-creating solar cells and energy-saving products, the net reduction in greenhouse gases will more than balance out the level of emissions by fiscal 2010.
For fiscal 2006, greenhouse gas emissions were approximately 1.73 million t-CO2. See this for details
In contrast, the reduction in greenhouse gas emissions resulting from energy created by solar cells was approximately 560,000 t-CO2. For details on how this figure was calculated, see below.

Calculation Method
The reduction in the amount of greenhouse gas emissions for the reference fiscal year is calculated by multiplying the CO2 emissions intensity (emissions per kWh of electricity consumed)*1 by the assumed amount of power generated by photovoltaic power systems. The assumed amount of power is the amount of electricity generated in the reference fiscal year, assuming that all the photovoltaic power systems produced by Sharp over the 20-year period prior to the reference year are in operation by customers.

The assumed amount of power generated in fiscal 2006 was 1,322 GWh, and this figure was calculated based on the following formula.

Assumed power = power generated by photovoltaic power systems (manufactured over the past 20 years) [1] X annual insolation [2] X (1 - power conditioner losses [3]) X (1 - other losses [4])

Assumptions on Which Calculations Are Based
[1] Power generated by photovoltaic power systems: 1,272 MW
· Total amount of solar cells produced by Sharp from 1986 through 2005 (20 years).
[2] Annual insolation: 1,430.8 kWh/m2/year
· The amount of solar radiation measured when installing solar cells tilted at an angle 30° facing due south in Osaka (Japan), the location of Sharp's Head Office, as published in the National Mean Solar Radiation Data Map (NEDO).
[3] Power conditioner losses*2:
· Assumed to be 10%.
[4] Other losses (losses due to temperature rise in solar cell elements, losses from wiring resistance and contamination blocking light at solar cell surface, etc.):
· Assumed to be approximately 19%.

*1 Calculated using the figure of 0.425 kg/kWh (for fiscal 2005) for CO2 emissions intensity (emissions per kWh of electricity consumed) announced by the Federation of Electric Power Companies of Japan.

*2 Power conditioners are devices to convert the DC power generated by solar cells to AC power.
