The present situation of solar energy in the U.S. and Japan

Solar is a sustainable use of clean energy. In search of sustainable development of human society, building energy-efficient for the increasing use of solar energy is getting worldwide attention.

The status of the use of solar energy in the United States is improving!

U.S. total energy consumption in buildings up to 30% -90%. There will always be some form of economic links role in development. Therefore, development of the United States of solar energy is growingquickly.

To reduce energy consumption, reduce pollution and adjust energy structure, to achieve sustainable development, made the U.S. successful exploration of the solar energy. "One million solar roofs plan" is the largest of the progressive realization of the project plan. The U.S. plan is the 21 century by a government of interests aligned. This is a development plan in the medium and long term. With the implementation of this plan is a million roofs or buildings are installedsystems with solar energy, including solar photovoltaic systems, solar water heating and solar air heating system. The implementation of this plan will be further expanded the applications of solar energy to reduce greenhouse gas emissions, expanding energy choices and create new high-tech jobs. It will generate significant environmental benefits and economic benefits. By 2010, millions of roof to be equivalent to the production of 2-3 coal-fired power power. Notonly his need for electricity, but also able to sell electricity generated by solar energy.

Recently, U.S. scientists find new energy to the far reaches of space. Scientists expected the launch of the satellite energy recovery device. The solar panel can be installed on the satellite to collect energy in space, and the collection of energy such as microwaves transmitted to Earth, and then converted into direct current. It provides cheap, clean, safe, reliable, sustainableEnergy.

Japanese current situation in the construction of solar energy is very beautiful!

As the second largest economy, Japan is the primary energy consumption in major countries, and are dependent on energy imports. But in recent years, Japanese energy-saving technologies to significantly improve energy efficiency is improving rapidly.

In the field of solar energy, photovoltaic roof system installed in Japan was 887,000 kilowatts by the end of2003.Japanese government plans to 4,820,000 kilowatts in 2010 for installation.

In Japan, solar energy is widely used in ordinary neighborhoods. The living quarters of the efforts of conservation of energy clearly promulgated by the Japanese and building standards. There are many specific measures for energy saving lighting. In energy-saving lamps are the living quarters in the Japanese joint application of solar energy, and is mostly passive solar home system.Absorbing roof panels that collect solar energy efficiently, there will be covered with thermal (cold) wind automatically Affairs. It can also provide hot water. The use of solar energy in residential area can not only save energy but may also improve, protect the environment. It 'also in line with the Community Building for Sustainable Development, energy saving in one direction. It 's always the attention of the Japanese government, support andEncouragement.

These two countries are very good for the solar industry. Their scientists are working very hard on this development of solar energy as well. There are a lot of obstacles to the development of solar energy. In the near future, the use of solar energy are more important than the lack of oil. Then it is time to pay attention to this area!
