In 2040, said SunPower solar power to meet the U.S. demand for electricity

Group co-founder of SunPower, according to Richard Swanson said that if the current pace of promoting the use of solar photovoltaic (PV) cells, solar cells by 2040 to generate electricity that is able to meet the U.S. demand for electricity. SunPower is currently president and chief technology officer, said Swanson, taking into account other renewable energy sources and new energy technologies are emerging at the same time, the 2050 solar cells provided by the growth in electricity consumption will be sufficient to reduce coal power generation as a result of the release of carbon dioxide. He pointed out that other renewable energy technologies such as wind and solar energy along with competition, batteries are growing rapidly. "We think that we (solar technology) can and other renewable energy technologies drive together," Swanson on August 26 at the hot chips of the General Assembly (Hot Chips conference) said. Swanson does not believe that solar energy can not keep up the growth rate of electricity generated by coal power. By reference and SunPower jointly by the U.S. Air Force, Nellis Air Force Base to build 14 megawatt solar power plant joint venture example, laptop battery Swanson said PV industry has been able to build a nuclear power station and about the same power supply capacity of solar power plants. Nellis solar power plant to be completed in December 2007, said its annual capacity of up to 10,001,000 watts 3 - hours.

Apple laptop batteries are also provided free of charge to replace

Apple recently announced that its production of notebook found on the battery, but this need not panic. This issue will not be like last year, "Sony battery door," like an explosion led to the fire, but will affect the battery life time. To that end, Apple recently released notebook batteries for the firmware update procedure, Battery Update 1.2, Apple needs to update the notebook products include: MacBook MacBook (2006 year-end period) MacBook Pro (15 inches) MacBook Pro (15 inch display smoothing) MacBook Pro (15 inch, Core 2 Duo processor) MacBook Pro (17 inches) MacBook Pro (17 inch, Core 2 Duo processor) Apple said that if the system automatically upgrade Battery Update 1.2, the following problems are still one or more of: 1. The system does not recognize the battery, battery desktop appeared on the chart "X",. 2. Connect the power adapter will not automatically after the battery charge. 3. In the number of battery charging and discharging no more than 300, the A1148 battery life significantly shortened. 4. Deformation of the appearance of the battery. For these users, you can contact Apple, the company will replace free of charge for a new PowerBook G4 battery . It is worth noting that because of this problem is not related to security, so even if the waiting time to replace the old problems of the battery can still continue to be used.

Renewable energy: how to "vases energy" to the dominant energy

At present, the international oil prices continued to rise, energy supply growing tensions, the deteriorating environmental conditions, many countries have begun to attach importance to research and development of renewable energy. In China, with the rapid socio-economic development, energy and the environment for sustainable development has become increasingly serious constraint. In light of these problems, the reporters here at the General Assembly on an interview with academicians of the Chinese Academy of Engineering, Energy and Mining Engineering academician of Huang Lai. Academician Li Huang, to energy conservation, demand total control, development of clean energy technologies, accelerate the development and utilization of renewable energy, optimizing energy structure, to fill the gap of conventional energy, environmental protection and reduction of greenhouse gas emissions an important way to the achievement of China's economic and social The only way to sustainable development. The development of the road map Although coal and oil and gas in the future is still quite a long time, major energy laptop battery , but China's oil and gas "reserve-production ratio" has reached the warning line, coal, "reserve-production ratio" is also far lower than the level in most countries. In response, Huang Li academicians, on China's renewable energy development need to establish a more positive goals, he will this goal can be summed up as the road map renewable energy development, renewable energy will gradually be added by upgrading to energy alternative sources of energy, The mainstream of energy and one of the leading energy. Huang Li-academician of the road map to the specific details were described: the recent (around 2010), non-hydro renewable energy strategic positioning is to add energy, can provide 060 million tons of standard coal equivalent of energy demand, accounting for the proportion of the total energy demand 2%: the medium-term (before and after 2020), non-hydro renewable energy is the strategic positioning of alternative energy sources, can provide 180 million -3.3 million tons of standard coal equivalent, the country's total energy demand of 5% -10%; long-term ( Before and after 2030), non-hydroelectric renewable energy strategic positioning is one of the mainstream of energy, to meet the 400 million -8 100 million tons of standard coal equivalent of energy demand, the country's total energy demand of around 10% -19%; long-term ( Before and after 2050), renewable energy is of strategic positioning one of the leading energy, to meet the 880 million -17.1 million tons of standard coal equivalent of energy demand, the country's total energy demand of 17% -34%. Weak "vases energy" Although the Government has to recognize that forward-looking development of renewable energy resources and strategic significance, and January 1, 2006 promulgation and implementation of the "People's Republic of China Renewable Energy Law," a number of other laws and regulations have also introduced, but some industries and regions Unclear in resources, industrial and other issues remained to be resolved weak circumstances, a quick success and disorderly development of symptoms, the need for scientific guidance. In addition, as the future direction of energy development, renewable energy in the early stage of development there are still some inadequacies, through economic and technological development so that it gradually rationalized. To solar energy as an example, Huang said Academician Li, solar cells in the production process will emit silicon tetrachloride, environmental pollution and, using solar energy is much higher than the cost of coal-fired electricity; In addition, from solar energy to supply patterns That the lack of stability. Again, bio-energy in the production process, the diversified technology will cause the diversification of products, some technologies such as methane gas produced only a low utilization rate of resources products, comprehensive utilization efficiency is not high compared with coal, bio-energy production Scattered distribution of raw materials, mining and use of high cost of transport. The development and use of water involved immigration, environmental protection and watershed issues such as distribution of economic benefits. "Every may foster a lack of new projects," Huang Li said. Development should have focused on Academician Li Huang, a family of renewable energy in hydro, wind, solar, biomass and other claims, and should be a clear development of their strategic focus. For example, wind power should be "land-based and network-based, pay attention to the development of distributed, speed up industrial building" solar energy should be "mandatory to promote the construction and use of the thermal technology, solar photovoltaic industry chain on the balanced development "Hydropower should be in protecting the environment and ecology on the basis of active and orderly development. For the current concern to the international community of higher bio-energy development model, Huang Li academicians believe that we should "not with the people for grain, and grain is not in dispute" and "not an agricultural land and water, not fight with livestock feed to ensure that food Security "under the premise of multi-start, with the passage of time, non-grain liquid fuels and alternative oil-based products will become of strategic focus. Specifically, the recent can use more mature type of non-food starch and sweet sorghum production of ethanol, a large-scale production, promote long-term study can be considered second generation of bio-liquid fuel technology, agriculture, forestry, waste utilization in the production of cellulose Bioethanol and biodiesel, the scale of alternative fuel oil to protect the security of energy supplies to contribute. "Fossil energy is the sun yesterday to give our mothers, renewable energy is the sun today to give our mother. A new energy revolution will occur, we can better use of renewable energy, fossil energy left to future generations." Huang Lai Academician said.
