Solar is a sustainable use of clean energy. In search of a sustainable development of human society, energy savings attributable to the growing use of solar energy attracts global attention.
The status of the use of solar energy in the United States is improving!
In the U.S., the total energy consumption in the construction of 30% -90%. There is always a form of economic development role restrictions. Therefore, the development of solar energy in the U.S. is growing very fast.
To reduce energy consumption, reduce pollution and adapt the structure of energy, sustainable development, the United States have a positive exploration of the solar energy. “A plan of million solar roofs” is the largest in the progressive realization of the project plan. The U.S. plan against the 21 century by a defender of the government. This is a medium-and long-term development. For the implementation of this plan there will be a million houses and buildings are built with solar systems, including solar photovoltaic systems, solar water heaters and air heating. For the implementation of this plan, the application of solar energy technology will be further strengthened to reduce greenhouse gas emissions, increase the possibilities of energy and new high-tech jobs. Brings significant environmental benefits, cost-effective. In 2010, millions of coverage are equivalent to 2-3 plants producing electricity from coal. It not only meet their current needs, but also was able to sell the electricity generated by solar energy.
Recently, U.S. scientists find new energy in the far reaches of outer space. Scientists should the energy harvesting device to communicate via satellite. The solar panel can be installed on the satellite to capture the energy in the room, and the recruitment of the microwave energy is transmitted to the ground, and then converted into direct current. It provides cheap, clean energy, safe, reliable and durable.
Current situation in Japan in the construction of the use of solar energy is very nice!
As the second largest economy in the primary energy consumption in Japan is based in the major countries and is on energy imports. But in recent years, the Japanese energy-saving technologies to increase energy efficiency to significantly improve quickly.
In the area of utilization of solar energy, the Japanese system was installed per kilowatt photovoltaic 887 000 2003.Japanese end, the government plans to install 4.82 million kilowatts in 2010.
In Japan, solar power is very common in normal residential areas. The energy conservation efforts in the suburbs is clearly adopted by the Japanese building codes and standards. There are many specific measures for energy saving lighting. In the energy saving is common in the Japanese residential use of solar energy and mostly passive solar house. Absorption through the roof panels, the efficiency of harvesting solar energy, which is inside automatically with thermal (cold) wind than interior parts. It can also hot water. The use of solar energy in the residential area is not only energy but also to improve the environment. It is also consistent with the construction of community in the sustainable development of energy saving in one direction. It is the Japanese government, care, support and encouragement.
Both countries are very good in the industry of solar energy. Its researchers are working very hard on the development of solar energy. There are still many obstacles in the development of solar energy. In the near future, the use of solar energy will be greater than the lack of oil. Therefore, it is time to pay attention to this industry!
