Solar Selectives
On a smaller scale most of us already realize that the use solar power already is common place with many home and business owners. Plenty of neighborhoods have outdoor solar garden lights for landscaping or solar panels on a rooftop is a frequent site, especially in states where sunlight is more frequent. The benefits and technologies of solar power are now present on a much larger scale.
Thinking beyond the backyard or other household appliances powered by solar energy, the solar thermal power plant is an amazing technology that can impact communities. These plants convert the sun’s energy into a useable heat source. This heat then boils water resulting in the release of steam to generate electricity through a turbine in a similar fashion to a nuclear power plant. This technology can benefit thousands of residents at a time serving entire communities with solar generated useable electricity.
Other solar power technologies being perfected including a method that utilizes mirrors to redirect sunlight onto an oil filled pipe. The heated oil then boils water for the generation of electricity. Mirrors are used in another technique in directing sun’s energy onto a collector which rests a receiver. A generator is then powered by molten salt that flows through the receiver.
Other technologies in use also includes less direct solar power uses such as the collection of solar energy through large windows allowing heat absorbing materials in the walls and floors of buildings to collect heat. At night this heat is released to maintain a steady temperature throughout the building. In a similar method heat absorbing poles installed on a rooftop can heat liquid in cylinders that provides a home with hot water.
If there are any negatives to the use and applications of solar power it may be due to costs and advancing solar technologies are expensive and they require large amounts of land in order to allow enough energy to be collected to impact an entire community. Thanks to new developing technologies and international recognition to the benefits of solar power, the push for using solar has increased by more than 20% since 1995. Solar panels used to be very expensive to develop but prices have dropped significantly and they are more efficient leading to the development of new major international markets. Cost incentives to go solar from our government permits the investment in solar electricity even more worthwhile allowing for a system to be paid for in five to ten years.
