Solar and wind power are____ and safe forms of energy that are renewable and don't pollute?
Question:
Answer:
natural
Alternative?
efficient
renewable
NATURAL
natural
cheap. It already says renewable and they are anything but efficient.
CO2 free
free of carbon dioxide
efficient, cheap, alternate, abundant, natural
simple
solar,wind,hydro electric power are efficient enough right now that they being combined in an area such as upstate NEW York could work as a unit in all sorts of weather conditions and don't forget about bio mass and co gen and clean coal and geothermal technologies along with the struggling hydrogen cell.
Hi Priscilla,
Do you normally post the same question twice in a row? Well here it is again.
If you want to get extra credit, the other two answers are what may be expected because wind power and solar power are both "abundant" and they are "alternative" sources of energy. "Renewable" may be the best of all of them though, because it goes along with the new political savvy about alternative sources of energy. "Abundant" may not be truly correct though; because, the wind ebbs and blows according to the locale and predominating weather conditions, most specifically, low pressure zones, and all it takes is a single cloud to reduce the efficiency of a solar electric panel down to 30%, and if its totally and darkly overcast, as little as 20% of the power that a solar panel is capable of producing may be all that it will give.
As far as being "safe" goes, what is totally ignored with these two types of power however, is the manufacturing process used to create them in the first place! A single boule of solar cells, grown in a furnace, can use up immense amounts of energy. Even more is used to cut the boule into flat wafers, and more is used yet to polish each wafer to exacting specifications. Then, for every 3 boules produced, only one is suitable to cut solar cells from. Now what is used to produce the energy to produce each viable boule? Yep, you guessed it...fossil fuels, either diesel or coal.
So when you answer this question, force the teacher to tell the entire class the WHOLE truth...bring this up.
cheers!

SENSIBLE. Our gang always quotes Amory Lovins...least cost first! Insulation, air tightness, CF bulbs, high-performance doors and windows, conservation measures. And yes solar and wind are a huge improvement and do not produce carbon.
