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, energy efficient building for the growing 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 growingvery quickly.

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. By implementing this plan will be a million roofs or buildingsinstalled solar systems including solar photovoltaic, solar water heaters and solar air heating system. be extended to reduce emissions of greenhouse gases through the implementation of this plan, solar energy technology applications continue to expand 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 electricity from coal-fired power 2-3Plants. Will not only sell their electricity needs, but also capable of generating electricity from 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, sustainable energy supply.

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 kilowattsuntil the end of government plans 2003.Japanese 4,820,000 kW in 2010 for the 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 compact fluorescent lamps are the living quarters in the Japanese joint application of solar energy, and is mostly passive solarHome 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 governmentSupport and encouragement.

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!
