The sun is at the helm of all life on the Earth. It is a virtually inexhaustible energy source that all living things, including us humans, need to grow and thrive. The sun converts its own mass into light particles known as photons. It charges the Earth with trillions of photons that fill the atmosphere each moment. The truth is, the sun supplies more energy in a single hour than all of humanity uses within one year.
A French physicist named Edmund Becquerel discovered in 1839 that little amounts of electricity were produced by the sun’s energy. Since then, solar energy knowledge has escalated to what we know it as today. Solar energy has been touted as the new way to produce electricity without harming the earth and creatures. But what do the real facts show?
Advantages Of Solar Energy
As long as the sun rises in the sky, using solar energy will be completely free. And if you are able to produce more energy than you need, many utility companies have programs where you can sell your excess energy back to them. There are also numerous grants available for individuals who switch over to solar energy, along with local and federal tax incentives for people who install solar energy in their home or place of business.
Using solar energy is better for the environment because it doesn’t produce pollution like so many other current sources of energy do. Because solar panels cost is becoming increasingly cheaper and more advanced, it is now more affordable to switch over to solar energy than in the recent past. Some consumers have even chosen to build their own with the low startup cost of only around a few hundred dollars. Because solar energy is renewable, the only cost is for startup.
Because in some remote places it is more difficult to install power lines, solar energy is a great alternative as the panels can be installed virtually anywhere there is unused space.
Having solar panels installed on your property can make the value of your property go up because of the reduction in the home’s energy costs. Current solar energy panels have a life-span of 30 years or more if maintained properly.
Converting to solar energy can be quite costly. And depending upon how much solar energy you want to produce, a reasonable amount of space is needed to produce the level required.
Solar panels are very expensive and even though the newer panels are able to makeup the shortfall in energy produced because of pollution and clouds, the older panels don’t have this ability. So if a person is slowly working towards getting “off the grid” by purchasing solar panels as they afford them, technology may be one step ahead of them by continually upgrading the panels ability to harness the sun’s energy.
Because the solar panels only collect energy during the daytime, an added expense of solar battery chargers is needed to lower that negative effect.
Solar panes contain photo-voltaic cells which can be damaged by pollution.
Strong winds or storms can also damage or blow the panels away, and many people who installed them solely as a backup to power outages will lose out on any energy they did gather.
To fully understand the advantages and disadvantages of solar energy one needs to have an understanding of where our own energy comes from. Many non-renewable energy sources we use are causing global environmental problems such as global warming. Meanwhile, solar energy is a non-polluting, clean and renewable resource. Also, solar technology is constantly evolving. And while your personal situation may dictate the appropriateness of the solar energy for your own needs, it is important to know that above all the energy sources we use, solar energy exhibits the most long-term potential for resolving the global energy problems.
