Why Solar Power Now?
As the pace of global warming and abnormal weather phenomena keeps up, we are forced to find global solutions to environmental problems, such as placing controls on carbon dioxide emissions and finding ways to conserve resources. Solar energy has low environmental impact and is available in an inexhaustible supply. It continues to be commercialized and is coming into more widespread use.
Clean Energy
Because operation of the system generates no noise or carbon dioxide, it is considered a clean type of energy.
- If a 4 kW system were installed in each of Japan's nearly 26 million private homes, approximately 100 billion kWh of energy could be generated annually.
- A 3 kW residential system can reduce the annual extraction of carbon dioxide (carbon conversion) by 540 kg-C as compared to oil-fired power.

Inexhaustible Energy
Solar energy is not an underground resource like petroleum or natural gas, and there is no need to be concerned about the source drying up. The volume of energy is limitless, and the amount of solar energy that hits the Earth in one hour is said to be equivalent to the world's annual consumption.
The spread of solar energy use can also help to save fossil fuels.
