The old siding on my home had finally reached the end of its lifespan. This meant it was time to re-side my home. After doing some research, I knew what features I wanted for my new siding. One of the features that was most important to me was the appearance of the siding and how it would increase the curb appeal of my home. Siding wraps around your entire home and can make it look old and dated, or new and modern. With this website, I hope to discuss different siding products and discuss what sort of appeal and look it can bring to your home. This can help you select the siding type that will impact the overall appearance of your home for the better.
It is common knowledge that solar power presents one of the most eco-sensitive energy alternatives available today. However, relatively few people understand the scientific or business side of this renewable source of power. That leaves many consumers wondering why there is not a more rapid move to solar energy as a primary source of power for the world.
With a few insights into the challenges, you can better appreciate why, after more than a half-century of development, solar power today provides only .03 percent of the energy consumed in the United States.
A Promise that is Difficult to Fulfill
Solar collectors and photovoltaic cells are currently the two primary ways for practical generation of solar power in usable quantities. The amount of energy in sunlight that is actually converted to electricity is expressed as its efficiency. The great limitation of these two methods is their efficiency, which today hovers around 20 to 25 percent.
While such a level of performance is adequate for solar panels in some applications, it simply doesn't provide the economics and practicalities for widespread use. In fact, it is estimated that current technology would require at least 10,000 square miles of solar panels to meet the power needs of the U.S. That area is greater than the combined size of Rhode Island and New Hampshire, and represents an unimaginable economic investment.
Even if such a solar field were built, there is another reality of physics that would limit its usefulness. The electrical grid that supplies the country with electricity suffers transmission losses of 20 to 30 percent, and such line losses become greater over long distances.
The third complication in the equation is the requirement for dependability and availability. As many areas of the country, and the world, simply don't have adequate year round sunlight, they aren't currently candidates for solar as a primary source of power. Given the need for large areas dedicated to solar collection, along with losses of generated power over great distances, these factors are behind the current lack of market penetration.
Much of today's solar research is focused on increasing the efficiency of photovoltaic cells to increase the use and practicality of rooftop and pole mount solar power. Direct solar in the right geographic areas presents sufficiently attractive returns on investment to justify its use in remote and off-the-grid applications. Likewise, rooftop installations currently offer paybacks of roughly 12 to 20 years, depending on the location.
The more exotic areas of solar research are seeking breakthrough methods of harnessing the sun. It is these efforts that provide hope of someday allowing solar power to fulfill its potential as a primary source of clean, global energy. Until that day, you will not see solar playing a major role in the effort to replace fossil fuels. However, you can still purchase solar panels for your home, from a company like DPW Solar Electric, and do your part in using renewable energy.Share
