Solar Living News

If you use solar power to provide light in or around you home, such as outdoor solar garden lights, the light present is delivered through one or more LEDs or Light Emitting Diodes. The LED is specifically made to release light and to do it efficiently with minimal energy absorption. The diode itself is contained within a plastic casing designed to promote the release of light in a specific direction. A large portion of the light produced inside the casing bounces off the side walls before its release through the rounded end.

There are many great advantages to LEDs compared to conventional incandescent bulbs. The LED doesn’t include a filament that ultimately burns out requiring regular replacement. This resuts in an LED bulb lasts much longer often up to 20 times longer operating life. Strength and durability is also a factor as the tough plastic casing of the LED is much more damage resistant than traditional bulbs. Modern electronics also welcome LED bulbs much more than larger bulbs as they can be easily integrated into many designs where light is needed.

Beyond the physical advantages to the LED bulb, it is their energy efficiency that is most recognized. Incandescent bulbs emit lights thanks to the high generation of heat as the internal filament requires this to operate.  As a result a great deal of energy is expended to heat the filament for the production of light. Most of the generated heat escapes nor is it used to generate the visible light. Now LEDs inside your electronic devices or your solar powered garden lights generate barely any heat and just a small amount of energy is required to produce light. The end result is very beneficial to consumers as the cost and use of electricity is greatly reduced thus saving money and energy.

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.

Everywhere you turn, whether in advertisement or just in general discussion, the social catch phrase now seems to be “go green”. Whether its energy conservation or natural and organic lifestyle, the word green has taken on new meaning over the past decade.

When it comes to the environment and energy alternatives, solar energy and the global advantages it creates, is at the forefront of the green energy movement. All other energy sources we use are limited or produce harmful by-products. Nuclear energy has radioactive waste and we all know the political and public hot potato that source is. Also, there’s no such thing as clean coal and we know that electrical power is another form of dirty energy that also is not in endless abundance.

Now consider solar power, the ultimate alternative energy source that will be available providing that our sun continues to rise. However, tapping into this ultimate source and converting it into useable energy for all societies is the challenge that lies ahead. As we all know great advancements have already been made in this field and will continue to move forward.

Every day the sun provides enough solar energy to power the globe for a year. Despite continued advancements in the collection and utilization of solar power, just one tenth of one percent is harnessed towards the global demand of energy. Now according to a recent National Geographic story, solar photovoltaic (PV) technologies could generate enough electricity equal to 40 times the world’s present electricity use. Photovoltaic cells, or solar panels, are a familiar site to most as they are commonly seen on roof tops, outdoor solar garden lighting, in calculators, and of course used on NASA spacecraft. When sunlight heats these solar panels electrons are released from their atoms resulting in the generation of electricity as the electrons flow the solar cell.
