Fun Facts About Solar Energy

There are tons of cold, hard facts about solar energy out there, but what about fun facts about solar energy?

While solar energy and its related renewable energy cousins, such as wind, geothermal and hydroelectricity, are serious business and options that are being considered to be potential saviors of our planet as we look at a future that has the threat of global warming hanging over it, i am not saying to say there’s not a lighter side to solar and renewable energy.

Sometimes you’ve just constantly some fun and let off some steam in amongst all the serious business of saving money and preserving the planet, so let’s do just that and check out some fun facts about solar energy.

1. Solar energy is available to us in 2 forms – light and heat.

2. When you open your drapes each morning to let some light in, were you aware that you’re also heating up your home?

3. The speed of light is 186,282 miles per second and it takes light approximately 8 minutes to reach Earth. So, light covers the distance of over 90 million miles from the sun inside of 10 minutes!

4. Particles of light are called photons.

5. The “photovoltaic effect” was discovered in the 19th century by French physicist, Edmund Becquerel, when he noticed that when light struck a semiconductor material such as selenium, it generated a small electrical charge.

6. The word photovoltaic is a variety of the words “photon”, meaning, a particle of light, and “volt”, being a measure of electrical force.

7. Modern solar cells operate using the photovoltaic effect, with silicon acting as the semiconductor.

8. Next time you eat Springlike chips, don’t throw the tube away. You need to use it to heat hot dogs! It’s true. You just need the can, a skewer (slightly longer than the can), copier transparency and Scotch tape. Cut a rectangular opening about 6 inches by 3 inches in the heart of the can in an attempt to create 2 flaps. Pull the flaps back and cover the opening with the transparency. Put a hole in the metal end of the can and one in the plastic top. Thread a hot dog onto the skewer and put the skewer inside the can so one end goes through the hole in the metal end and then thread the hole in the plastic top over the other end of the skewer, in order that the skewer with the hot dog on it is suspended during the can. Take the cooker out and place it in direct sunlight, adjusting it here and there to ensure it’s tracking the sun, and, within 30 minutes or so, you ought to have a freshly cooked hot dog!

9. In the 19th century, John Herschel, a British astronomer, cooked food using solar thermal heat while on an African expedition (Absolutely suit, what did he cook?!!??! A hot dog?).

10. Solar panels and solar collectors are different. A panel converts sunlight to electricity and a collector absorbs heat which it transfers to air or liquid.

11. The sun beams down more energy in 1 hour than the whole planet can use in an entire year.

12. Solar energy is used to power more than 10,000 houses in the U.S.A.

In the serious world of solar, a world that sometimes takes itself too seriously, it’s good to let off steam and lighten things up a bit and just have some powerful fun. Hopefully, these facts made your solar day a little more fun.

The Popularity Of The Electric Vehicle

Without a doubt, pollution due to smog emissions has caused significant damage to our planet, environment and natural resources. We can clearly see the derogatory effects of our oil dependency in the current global warming situation, which is rather alarming and cause for serious concern. Despite the International Oil Embargo in 1973, the United States is still continuing to increase its import of oil volume wise. We Americans have become quite accustomed to driving our big SUV’s and cars. Luckily there is a solution in sight for this dilemma and that is the mass production of the electric auto.

At the turn of the early nineteenth century, electric cars were actually more popular when compared with combustion engines vehicles. Unfortunately, what gave way to this preference was the cheaper price of combustion engine vehicles and the lower price of oil; both of which were championed by the major automotive companies in the United States.

Pretty much all of the vehicles built in the twentieth century all had combustion engines. Experts and scientists have recently confirmed that humans are largely responsible for the planet’s global warming and a large part is due to our cars averaging nineteen pounds of carbon dioxide emissions for every mile driven. However surprising it may be, around the nineteen eighty’s the large car manufacturer GM had begun gaining attention for its focus on alternative energies in light of this looming threat. During this time, there was further pressure for auto companies to design and manufacture “clean” products. For example, the state of California had passed its “Zero Emissions Mandate,” which required there to be a certain percentage of cars manufactured that emitted significantly less carbon dioxide and pollutants. And in the 1990’s GM assigned Saturn to market the EV1, the first electric car ever built for mass consumption on a large scale.

Saturn’s marketing campaign for this vehicle focused on a threefold consumer question: how far? how fast? how much? From the very start the car attracted what seemed to be major interest. In fact, there was a long waiting list of people who were interested in purchasing this car. Interestingly, GM did not put these cars up for purchase and were only willing to lease them. Nevertheless, the drivers were euphoric about the EV1 as it produced zero CO2 emissions and was fast and fun to drive. Clearly, these drivers actually preferred electric over combustion, despite the car only averaging 60 miles per charge. Thus, the clean, quick and sleek electric car was more desirable than its “nuclear time bomb” counterpart. Are you curious to find out what happened to this environmentally friend vehicle?

The auto makers insisted that there was no strong consumer interest despite having put millions into campaign ads, and that the waiting list was not a viable source for proving actual demand. Eventually, the hype was killed with GM removing all leased EV1s from the streets and turning them into demolished cubes. In defense of these roguish actions, among many other discussions, the auto industry argued that electric cars, because they were charged with electricity produced by coal, were even more detrimental for the environment. On top of this, the oil industry supported arguments against this emerging technology, and President Bush pushed for the inefficient and impractical fuel cell and hydrogen technologies to be the wave of the future and replace combustion engines.

The fact of the matter remains that this energy efficient electric car was repressed by the car industry on purpose. The government and oil industry also played a large role in this. What is even more shocking is that we as consumers did our part to support such actions by passively watching the advent of the electric car slip through our fingers. Luckily it is not too late to get this technology back and mass produce it. The EV1 was incredible and any car enthusiast would enjoy taking it out on a spin. Lets take the steps and measures necessary in order to make this car a reality.

Why Pay $1000’s For Solar Power Systems When You Can Build Your Own

Solar power electrical power is becoming easier to implement. You will find excellent new items with directions that you can purchase which will show you how to construct solar panels and install them in a short amount of time. The materials that you will need could be bought for much less than $200 at your local hardware shop.It isn’t unusual for the person who installs home photo voltaic power systems to cut hundreds of dollars per month on their bills from the energy companies. Some households have saved from 50% to 80% on electricity payments.

How Solar Panels Function Photovoltaic cells within solar panels use a semiconductor material (such because the silicon utilized in computer chips) to straight convert sunlight into power. Sunlight striking the photo voltaic cells release electrons from atoms in the silicon. Electrical conductors are attached towards the photovoltaic cells to capture the electrons in an electrical circuit.

The program of grid-off solar power offers power to remote structure which utilize photo voltaic panels, charger controllers, wiring cables and battery although the grid-tie photo voltaic power program is directly connected to your electrical energy organization. During the day time with this kind of program; your solar power is straight generating energy from your primary grid. It then records this and “saves” the power and when night time comes; you are able to draw whatever energy you have put into the program during the day time, and you can use it at night. This kind of method can be used only in residential area.

So what benefits can a household get should they make use of this energy supply for their houses? Nicely, it is 1 great way to supply and sustain the lighting of your home. It is one of the bare necessities that your home ought to be lighted and lighted nicely. If you can generate your personal electricity from the sun, you are able to turn on as numerous lights as you want without having to worry about your electric bill.

You will find 2 kinds of systems depending on exactly where you want them placed. Either about the best of the roof and ground mounted ones. This all depends on how much power you’ll need for your house. Those who have a bigger whole lot or property, ground mounted may be much more advisable for them.

Planning to possess one installed demands cash and knowledge. If you plan to possess this photo voltaic panel system inside your house or you should also calculate the size of your house and calculate your energy consumption on average. Ground mounted systems on the whole are simple to maintain rather than in the roof top. As you know, each solar panel program can hold around 20 panels on a single rack and you are able to make a durable mounting for that solar enegry.

In the topic of photo voltaic cooking, there’s a solar box cooker which is used to literally trap the sun’s power into an insulated box, which can then be utilized for cooking. In regards to photo voltaic lighting, the entire interior of a building – such as your home – could be lit throughout daylight hours utilizing light tubes, and generally, it’s claimed that this really provides the interior a much more natural light and could be used to decrease the power demands of electrical lighting.

Planning to possess one installed demands cash and knowledge. If you plan to possess this solar panel system inside your house or you should also calculate the size of your house and calculate your energy consumption on average.
