Earth 4 Energy Review
February 26, 2010
It is no doubt that most citizens are bothered by the problem of huge energy cost every month. And all of us know clearly that without energy, we can barely live a single day! Is there a perfect way to solve our problems? Mr. Michael Harvey helps us find a way in his wonderful e-book—Earth 4 Energy.
Earth 4 Energy is a thorough e-book which will help you to build up your energy system step-by-step by your own hands and in your own way!
With the rapid spread of the wave of renewable energy, there appear various books that introduce how to set up an energy device. However, undoubtedly, Earth 4 Energy is the best choice. Not only because it proved itself on the market in the first place, but also it has far more detailed information than its competitors as well as great reputation in the alternative world.
With simple and doable instruction, massive explanation of photos, illustrations and diagrams plus an assistant video containing the whole process, you are able to DIY a solar panels or wind turbine as your wish. Furthermore, Earth 4 Energy has fine service afterwards. You can send e-mails whenever you come across with problems in making the device, and will get satisfied answers in short time. In addition, you can sign up to attend the forum to communicate with other guests.
How beautiful! Giving only $49.97, you will install an energy system, cut your high energy price and protect the environment! You get three birds with one stone! What a bargain!

what are some factors that affect the amount of solar energy that reaches the Earth's surface?
i am confused i can not find this in my notes its for a exam review…what are four factors that affect the amount of solar energy that reaches the Earth’s surface?
It depends on if you mean a small part of the Earth’s surface, like for example your city, or if you mean the Earth as a whole.
For a small part of the planet, the amount that reaches the surface will be affected by weather (especially clouds), time of day (obviously you get more at noon than at dusk), time of the year (you get less in the winter), and air pollution (natural or man-made).
Globally it is mostly constant, but it does change based on small variations in the amount of radiation coming from the sun. Of course, this will also have an effect locally, but not as the local effects do.

Solar energy to human and to entire planet … are two different categories. Solar energy for human means, the direct sun light humans use to convert into electricity and that solar energy is affected by following four factors —– 1) rain clouds which are dark in nature and block most of the sun light 2) dust particles within city area, ash particles in coal burning areas 3) fog/smog mostly during winter season which blocks visibility also 4) other pollutants like smoke/fuel emissions/vehicle and industrial air pollutants
For the solar energy to plants/animals/entire planet the four factors are — 1) dust particles 2) green house gases which brakes the ozone layer and brings harmful ultra violate light inside the earths atmosphere instead of clear and healthy sunlight 3) other pollutants like smoke/fuel emmissions/ vehicle and industrial air pollutants(pollution created by humans) 4) clouds/fog/smog mostly during winter season which blocks visibility also

incomplete question but here goes, my answer is slated toward PV solar
orientation: what latitude you are at has effect on energy the closer to the equator the more power full
(solar panel in the us are always pointed true south to harvest more power)
altitude: higher altitude receive higher amounts of irradiation
(Denver has less sun hours in reality due to its more northerly position on the planet than Los Angeles per yer year but maintains a higher isolation ( sun hours) value due to altitude)
weather: a climate that is constantly cloudy will receive less irradiation.
(the Mojave desert will have more sun hours than Los Angeles due to weather it is virtually same the spot on the earth and has almost identical sun up sun down values)
tilt: what time of day it is will have an effect on irradiation due to the tilt of the earth
(noon will have the strongest irradiation because of angle to the sun
