Solar's future

Night-time solar power generation is not a major drawback,laptop batteries,but for this there are three kinds of weaknesses can be overcome.
1. The solar cells as power supply program: as a result of higher electricity demand during the day, a simple solar cells only during the day just to provide services for power plants can supply the load more evenly,acer laptop battery, but also to reduce the peak load power grid.
2. The sun light during the day and into other forms of energy storage, such as batteries, flywheel devices, compressed air,acer btp-43d1 , power plants take out to night time and then release the stored energy.
3. The United States and Japan are "Satellite solar power plant" project (Satellite Solar PowerStation, SSPS), a plan the work of this project is to find a space to receive continuous sunlight, such as near the equator over fired with solar cells or thermal power generation system of satellites, the use of satellites in space to absorb solar energy to generate electricity. Because from the day and night, such as temperature and climate factors, and the satellite can be kept stable for receiving solar energy, then it is converted to electrical energy, and then microwave the way back to Earth,travelmate 220 battery, after the earth station to receive the microwave and then conversion returned as electricity, transportation to various places.
The cost of solar cells is currently high - than a lot of green / renewable energy is much higher and can not provide a reasonable cost,acer btp-58a1, high demand.
Can look forward to scientists and engineers continue to study the semiconductor industry coupled with technological progress, the efficiency of solar cells also gradually increased, and the unit cost of power generation systems are declining year after year. Thus, with the increase in solar cell efficiency, reduced costs and rising environmental awareness,ace btp-60a1, the cost of solar cells is expected to greatly reduced.
Now, the solar cell has been widely used in daily life, such as watches, computers, cars, planes, etc., we can see it has great potential,travelmate 240 series battery , I believe the future of solar energy use can play an important role.
Can also make use of cheap sun reflection in the mirror will be to expensive high-efficiency solar cells (need to pay attention to heat), ace btp-52ew,can reduce the cost of power generation.
The world under the general concept of energy conservation, green technology is the current star of the industry. The trend of this wave of green technology, but also having the most solar energy rising, it is possible Hongtoushan hold up half the world's rising star. The face of high international oil prices, the third oil crisis in the coming crisis, a re-shuffle the world's energy card digital warfare,ace btp-63d1,ace btp-42c1 , acer btp-44a3 , acer btp-550p , acer btp-73e1 war has been sounded like a drum, poised to take off.
