Earth 4 Energy

Archive for January, 2010

According to this link Europe uses 4,000 terawatts of energy but in the normally unusable deserts of North Africa and the Middle East 630,000 terawatts fall unused. If solar thermal plants covered the desert about the size of Austria it could power the whole entire world. The technology is cheap and includes an ability to store the energy for nighttime needs. If all this is possible why are Earth are we not employing this clean, cheap, abundent source of energy?

In a previous lesson you learned that the main power source for global weather is the ________.
wind
oceans
the sun
the moon
Which part of the earth’s surface receives more direct, intense solar radiation?
the equator
the poles
the Prime Meridian
the Southern Hemisphere
Which parts of the earth’s surface receive less direct, less intense solar radiation?
the equator
the poles
the Prime Meridian
the Southern Hemisphere

4% D) ___ of the solar radiation entering the atmosphere is reflected by the clouds.
51% E) ___ of the solar radiation entering the atmosphere is reflected by the atmosphere.
Weather systems are set in motion
when solar radiation is abosorbed by the clouds.
by the radiation of heat back into space from the earth.
by the unequal heating of the earth’s surface.
by the heating of the clouds and atmosphere by incoming solar radiation.
The greenhouse effect is important in keeping the temperatures in our atmosphere relatively stable.
True
False
The greenhouse effect becomes a problem
when there is an increase in solar radiation.
when there is an increase in the amount of greenhouse gases in the atmosphere
when green plants produce too much oxygen, increasing the amount of oxygen in the atmosphere
It is believed that increasing amounts of greenhouse gases in the atmosphere will result in
higher average global temperatures.
cooler average global temperatures.
no changes in average global temperatures.

The Earth4Energy guide does its part in helping you become independent from other sources of electricity other than your own. People have used oil to power their homes and so much of the earth has been ruined from this. The kit is the best buy you’ll ever make because you can now power your home with renewable energy.

The guide created by Michael Harvey is everything you need to make everything possible. Plus, you will be more than satisfied with it, and that is a guarantee. You will not be asked to take risks and you can easily download the PDF online anytime you want. The main purpose of this e-kit is to provide you with a comprehensive guide on how to generate renewable source of electricity by building and installing either a solar panel or a wind turbine. You can even do both is you want to just in case you need sources for both sunny and cloudy days. The materials that you’ll get cost $200 at most, and in return, you will see a big improvement on your savings.

Moreover, the guide emphasizes on ways to go environmentally friendly. Traditionally, people have been burning fossil fuels in order to power their home. The fuels are very destructive to the environment is a non-renewable source of energy. You release pollutants such as sulfur and nitrogen oxides. This is no way to live. It’s time to think about your future right now because there will be none to speak of if you remain apathetic.
