Facts About Solar Energy
Author: Anna
With today's technology, we are able to capture this radiation and turn it into usable forms of solar energy - such as heating or electricity.
Although one could go into technical dissertations on the subject of electromagnetic radiation, how it is converted into solar energy, and the exact qualities of its electromagnetic rays, this is not something the average person needs or wants to know.
But in order to be able to benefit from the use of solar energy, there are a few facts you should know. Knowing these facts can assist you to make sound decisions, when looking at the use of solar power as a clean energy source for your home, RV, or whatever the case may be.
Environmental Facts about Solar Energy
All life on earth is dependent upon solar energy. In fact, without solar energy, there would be no life at all. Even the lowest life forms, such as plankton and microbes, need solar energy (in the form of sunlight) in order to survive.
Solar energy is completely environmental friendly, producing absolutely no carbon emissions or other harmful byproducts whatsoever.
Solar energy can be used successfully and cost-effectively just about anywhere on the planet. You do not need to live in a tropical or desert climate in order to benefit from the use of solar energy. Solar power has been used successfully in many cold climates and even in the polar regions.
Every area of the United States of America receives enough sunlight to benefit from and make use of solar energy and solar technology.
Currently, the cheapest and most effective way of using solar energy in your home is through the use of solar water heating systems. In fact, solar water heating systems have been commercially available in the United States for over a 100 years.
Solar energy can be used for heating homes effectively in cold climates, as well as in warm climates. In fact, for decades now, solar heating has been in use several cold-climate northern European countries.
Solar energy technology has advanced to the point where it can be now be a viable and cost-effective replacement for regular grid-electricity.
Solar energy is rapidly increasing in popularity - so much so that the demand for solar-powered gadgets is currently greater than the supply.
Facts about Solar Energy Usage
Solar energy can be used to provide electricity, heating and hot water for homes.
Solar energy can also be used to heat swimming pools. Many pools in Scandinavia and Europe are in fact heated with solar energy.
Solar Energy can be used to power vehicles, such as solar powered cars, and even a solar powered airplanes. NASA has successfully designed, built, and tested an airplane which is powered wholly by solar energy.
A few examples are: solar battery chargers, solar flashlights, solar calculators, solar radios, solar-powered attic fans, solar power backpacks (to recharge batteries for small devices), hybrid solar chargers (for cell phones, satellite phones, and more), solar-powered garden lights ... and much, much more.

can someone help me with facts about solar energy?
i’m doing a project on solar energy and i need help with the following question…..
1. Explain why solar energy is considered renewable.
2. Explain how solar energy is harvested and converted into a usable form. Name any major equiptment that is used. (Example: drilling equipment and oil wells are used to harvest petroleum.)
3. What are main uses of solar energy? (Examples: idustry, heating, electricity, making fuel)
4. How much is solar energy currently being used and who uses it the most? ( Which countries, states, people in specific areas)
5. What do you think the future will hold for solar energy? (will it be used more or less? will it have different uses)
6. Explain 3 disadvantages of solar energy.
7. Explain 3 advantages of solar energy.

Do you any of you know any facts about solar energy?
We have to do a project and I’ve checked everywhere and I haven’t found any cool information.
what are some facts about solar energy?
I am doing a science project and need some help on solar energy. Thanks! : )

Interesting facts on solar energy:
It takes 8 minutes 17 seconds for light to travel from the sun’s surface to earth.
In 5 billion years the sun will run out of fuel.
A Swiss scientist, Horace de Saussure invented the world’s first solar energy collector, or ‘hot box’ in 1767.
In the 1830s British astronomer John Herschel used a solar energy collector box to cook food during an expedition to Africa.
Albert Einstein won the Nobel Prize in 1921 for his experiments with solar energy and photovoltaics.
Enough sunlight falls on the earth every minute to meet the world’s energy demands for an entire year.
If we covered a small fraction of the Sahara desert with photovoltaic cells, we could generate all the world’s electricity requirements.
All TV and communications satellites are powered by solar energy using photovoltaic cells.
Here’s a few more facts:
Basic facts about solar energy:
•Solar energy reaches earth from the sun through its rays.
•Energy from the sun comes in the forms of light and heat.
•The term solar energy refers to the use of energy from the sun.
•Solar power more specifically refers to the utilization of the sun’s energy for electricity.
Facts about solar energy usage:
•Solar thermal technology makes use of the sun’s heat.
•Photovoltaic (PV) technologies convert light from the sun into electricity.
•Solar thermal technology can also create electricity by creating steam to power generators.
•The use of solar energy does not cause greenhouse gas emissions.
Other interesting facts about solar energy:
•In 1990, a solar powered airplane flew across the U.S.
•During the 15th century, Leonardo da Vinci already had plans for solar concentrators in his notebooks.
•In just one hour, the earth receives more energy from the sun than the entire world uses during a whole year.
I hope this helps a bit!!!
Good Luck!
1. most of the energy given off by the sun is in the form of visible light, that’s why our eyes have evolved to see in that range.
2. the amount of energy that hits the earth at the top of the atmosphere is 1.3 to 1.4 kilo watts per square meter
3. enough energy hits the earth from the sun to power every car, truck, train, boat, house, factory and all the equipment in the world many times over.
4. most commercially available solar panels convert 10 to 15% of the sunlight into electricity, but panels exist that convert up to 30%
5. simple devices exist which convert solar energy into heat at close to 100% efficiency (like black pavement). That heat can power a generator at up to 40% efficiency.
6. the wind is powered by the sun, so wind turbines are also solar energy collectors.
7. ocean waves are powered by the wind, so ocean wave powered generators are also solar energy collectors.
8. Most houses will end up with a surplus of electricity if they have 700 watts worth of solar panels, that can easily fit on almost any roof.
9. if a car uses 20 gallons of gas in a week, it would need about 3.5 kw worth of solar panels to feed it’s needs, that can also fit on most roofs.
10. the suns rays can be focused with a lens or a curved mirror to produce extremely concentrated beam of light that can produce extremely high temperatures.
