American Scientists Believe That Solar Energy Is Expected To Become A Preferred Alternative Energy

American scientists Travis Bradford in the newly published "Solar Revolution," a book predicted that solar energy will be in the next 20 years to become the best effect, the price of the cheapest alternative sources of energy, prices will drop 50% in 10 years, after 20 years of decline 75% .

Bradford is the Massachusetts Institute of Sustainable Development Prometheus founder and president. He said that over the past 10 years has been the development of optoelectronic industries to obtain electricity through photovoltaic cells become economical and practical. Japan, Germany and the United States and other markets around the world, tens of thousands of households and enterprises are using photovoltaic technology.

He wrote that the construction of large wind power or geothermal power facilities now require supporting infrastructure, use of these two methods of generating at least half of funds should be used in the transmission and distribution. Using solar power, without electrical power grid will be able to transmit directly to end-users, the cost is only to tenants to install equipment costs. At present, the supply shortage of fine silicon solar panels limit production. Bradford believes that this situation will change after a few years. First, according to those large and reliable polysilicon manufacturing enterprises, as well as some in the manufacturing metallurgical grade silicon has extensive experience in new business to increase the output of the current situation to 2008, will double the supply of polysilicon. In addition, chips and solar battery maker is studying how to make more effective use of silicon.

He pointed out that some of the world's developing countries are often rich in solar energy resources, but the lack of use of solar energy resources. The future of solar energy prices drop significantly, a household will be able to spend 50 US dollars with a generating power of 30 watts of solar panels, used to recharge cell phones and listening to the radio and so on. In the United States, major residential construction companies are considering new construction using solar energy problems. California passed a new bill on the request of construction companies in 2012 to allow tenants choose to use solar power. Bradford believes that the future five years, the United States will become a solar energy use one of the fastest growing, will be more than Germany and Japan as the world's largest country in the use of solar energy.
