Solar Energy – The Power of the Sun
See Related Article – The Great Earth Engine and 100% Renewable Realistic Goal or Pipe Dream or by Brian Oram
All energy of the planet Earth has it source from the power of a past or current Sun. The universe has been estimated to be about 14 billion years old, but our Sun is only about 5 million years old. Because of the presence of heavier elements, we know that the Sun and our system was likely created by the remnants of a second or third generation star. (WE are all children of a Star and Star dust). This means that the universe recycles and our Sun was created after a previous Sun went through least two or three supernovas. This left behind the building blocks for our current solar system. How did the first building blocks start? (I will let that up to you, but a good book worth reading by [amazon_textlink asin=’1621578984′ text=’Dennis Prager’ template=’ProductLink’ store=’webdespro-20′ marketplace=’US’ link_id=’8d849250-ec9c-43ce-b576-b95d430ee359′]).
Quote:
“Second-generation stars, such as the sun, contain some heavier elements. These elements could not exist just based on nuclear fusion inside stars. Instead, some of this material must have come from the supernovae of other stars. Hence, second-generation stars like our sun were formed after first-generation stars.” Source
Since the solar energy we get from our current Sun provides the solar radiation that is used by solar panels and creates the thermal differences on the planet to support wind and the water cycle, the gravitational pull creates the tides, and the radioactive particles help to support the molten core – The Earth is really powered by past Suns and our current Sun. Since we have to be honest, fossil fuels, including coal, oil, and natural gas, in reality are nature’s way to store solar energy. This means that fossil fuels are actually part of the natural storage system for the Earth, but they are not renewable in our short life-times, but they are renewable in geologic time. Because of this condition, we must learn and invest on other technologies, plus focus on conservation, hardening grid, adapting to a planet that has always changed, we must not rebuilding on unstable landscapes (“build on rock, not sand”), and we must make sure we have diversification in our energy platform. Since we are human, we must also use energy as “soft power” as an alternative to “war and the funding of totalitarian regimes”.
In this post, we are going to attempt to highlight some of the basic information related to traditional solar energy systems for residential and commercial applications and link to solid educational resources. To get a little in the weeds, we do not have an Energy Crisis, we have an energy waste and lack of storage crisis. In the USA, we waste over 50 % of the energy we use and we have a lot of “energy vampires”. Solar energy systems work well, but it depends on location, location, location, system design, system orientation, building efficiency, and building orientation. To take the first in the process of proactive positive change, it is critical to learn. The first steps in this learning process of making a difference and a proactive positive change is to “Learn, Question, and Act/Test”, but this must happen after your are ready to “Stand UP and Look for the Facts” and not play to the “Fear”.
Solar Power Systems
Solar power systems can be divided into three basic types, which includes active solar energy, passive solar energy, and solar thermal energy system. In active solar energy systems, the system includes a “panel” that may be roof, or land mounted with residential and commercial applications. The panels are photovoltaic cells that convert solar energy into an electrical current. With passive solar energy, the goal is to attempt to intercept and store or block and redirect the radiant energy created by the sun. Passive solar energy is managed primarily through building design, material selection, and building orientation. Solar thermal energy system typically is limited to storing the radiant energy of the sun and using it to heat water, such as in roof mounted water heating units to create hot water or systems to heat pools.
If you are interesting in learning about solar energy and its application for your home and may be ready to ask more question or act, we would recommend reviewing the website created by Consumer Affairs. Consumer Affairs created a helpful resource that allows consumers to determine whether their house is a good fit for solar panels and allows them to compare popular solar energy companies. With the help from contributing editor, Zachary Shahan, the guide addresses the types of solar energy technology and how solar panels work. You can read more and determine if solar energy is right for you on The 10 Best Solar Energy Companies guide.

Valley View Holds First High School Energy Fair Archbald Pennsylvania
“Northeastern Pennsylvania gas companies went to Valley View High School in Lackawanna County to sponsor an energy fair introducing youth to energy careers.
The growth and dedication that has been displayed between the natural gas industry and educational institutions over the years has been staggering. While much of that relationship has been amongst local area colleges, high schools have been becoming closely involved too, as evidenced by the Energy Education Program offered at Valley View High School in Archbald.”
As this blog has noted before, the Energy Education Program offered by Valley View is the first of its kind in the state, as it brings energy-specific curriculum to the high school level and was developed as a collaboration between industry experts and school officials. The course covers nine different types of energy and regularly features speakers from the various industries.
But on Friday, Dec. 18, Valley View took the next big step in its program and hosted its first Energy Fair, which was planned and organized by the Energy Education Program class.

The Great Earth Engine – Geothermal Energy for the USA
Reprint of article I wrote for Natural Awakenings Magazine
“When people think of renewable energy, their first thought is typically solar power or wind energy. As snowbirds return to their cooler climates, one natural and reliable renewable energy system is a geothermal or a ground-source heating and cooling system. These systems come with a variety of configurations, and a single system can heat or cool a home without natural gas, coal, oil or biomass. However, some electric power is required to run the system. This relatively obscure technology is robust, proven and available now to those willing to understand the simple beauty of these systems.
A geothermal system moves and stores energy rather than producing energy through combustion or resistance. Geothermal systems work by exchanging hot or cold air from the home with the stable stored energy in the ground, rather than by converting chemical energy to heat. This is a renewable energy system that is very efficient and has enough flexibility to fit a variety of applications. Some added benefits in addition to efficiency are that geothermal energy creates no pollution to our air or water and, other than electricity, they eliminate the need to purchase highly processed petrochemical fuel from less than environmentally conscious producers.
While the air temperature in northern climates can vary from season to season, the Earth’s temperature a few feet under the surface is essentially the same in winter and summer. In the winter, the system can heat a home using the Earth’s relatively warm core energy. In the summer, the same system can cool the home with the Earth’s relatively cool mass. Year-round, geothermal systems can produce hot water.
Geothermal heat pumps have an efficiency of over 300 to 500 percent (meaning they get a payback of three to five times the energy used to run the system). This efficiency provides the heating/cooling needs at a cost that is 30 to 70 percent less expensive than conventional energy systems, without combustion, carbon dioxide, methane, water pollution or the waste generated by other energy systems.
Geothermal ground-source heating and cooling systems work during the night, when the sun is blocked by clouds and when the wind is not blowing. While electricity costs may vary, geothermal costs don’t fluctuate like natural firewood, gas, coal and heating oil. The ground-source system comes in a variety of configurations to easily fit new home construction or homes with a more conventional, existing duct-based heating and cooling system.
The geothermal system has three main components: connection to the Earth, delivery and distribution system and a geothermal heat pump. The Earth connection allows the system to pull or store heat in the Earth. In heating mode, the system uses the Earth connection to pull a small quantity of heat from the Earth to heat a person’s space. In cooling mode, the system does the reverse and transfers heat from the air back to the Earth. The distribution system can be a series of vertical connections or loops buried in the ground that transfer and help to distribute the energy.
The geothermal heat pump is very efficient energy transfer system that moves the energy from the building to the transfer fluid. The system does require an electrical source to run the heat pumps and circulation system, and it is critical that an existing home have a formal energy audit done prior to installing a system.
New construction should use green building and energy efficient insulating systems so the system can be properly sized.
Users can benefit from lower energy costs, elimination of water and air pollution and a significant reduction of the expensive and environmentally destructive infrastructure of fossil fuels by adapting geothermal systems as soon as possible. ”
