Solar energy is green energy source because it is renewable and does not cause any harm to the environment. This is achieved by converting sunlight into electricity by solar cells. Three basic options on how we can use this form of green energy source, ie passive, active, and using solar cells. When we talk about passive solar, nothing is converted. What happens is the building's design helps prevent heat loss and gain maximum lighting during the day.
This technique can also be used in homes, because studies have shown that this can reduce the heating requirements by as much as 80% of the cost. This means that you do not have to activate the air conditioner or heating so often, and if everyone does that, we don't consume that much electricity which we get from non-renewable resources.
The second approach is active solar energy which is the first way to convert sunlight into heat. You should know that there are certain limits to it and all you can do is make sure you have hot water.
A language is therefore a horizon, and style a vertical dimension, which together map out for the writer a Nature, since he does not choose either. The language functions negatively, as the initial limit of the possible, style is a Necessity which binds the writer’s humour to his form of expression. In the former, he finds a familiar History, in the latter, a familiar personal past. In both cases he deals with a Nature, that is, a familiar repertory of gestures, a gestuary, as it were, in which the energy expended is purely operative, serving here to enumerate, there to transform, but never to appraise or signify a choice.
—Roland Barthes (1915–1980)
The third approach is the larger version and it can power an entire home or office. This is done with the help of solar cells that convert sunlight into electricity. Smaller version can be seen on calculators and watches and larger ones planted over a larger acres of land. The only limit to this source of green energy is that it can not produce energy when the weather is poor and the sun is down. In case of rain, then nothing is collected and converted. When this occurs, the backup system is activated until the weather improves.
Despite this, scientists and students themselves have made solar-powered cars. NASA and the National Aeronautics and Space Administration has sent satellites into space to work with solar panels. A fully functional airport can operate on its own thanks to solar power, even if it is in the middle of the frozen desert.
So people can see the awesome power of solar energy, did you know a kilowatt of solar energy can produce 5.5 hours of electricity per day. If you have more solar cells in place, of course, you will be able to produce enough energy to last several days.
Either over neither, both over either/or, live-and-let-live over stand-or die, high spirits over low, energy over apathy, wit over dullness, jokes over homilies, good humor over jokes, good nature over bad, feeling over sentiment, truth over poetry, consciousness over explanations, tragedy over pathos, comedy over tragedy, entertainment over art, private over public, generosity over meanness, charity over murder, love over charity, irreplaceable over interchangeable, divergence over concurrence, principle over interest, people over principle.
—Marvin Mudrick (1921–1986)
Solar energy is only a form of green energy source around. Over the years we have learned to exploit other resources, and these examples are wind, geothermal, hydro and biogas. All of them are safe and by using these more often, we need not rely on oil which is a nonrenewable resource.
To do this, we must convince our legislators to promote the use of these resources. Even if they have been talking about it for sometime now but nothing much has been done. This is something that must change. We can take the initiative and help save the earth by building our own green energy source.
