What are engineering challenges to develop solar energy for comfort/home uses?

June 8th, 2009

What are engineering challenges to develop solar energy for comfort/home uses? Solar is an old technology now and is fairly developed. Cost is a bit of a barrier but that is coming down quickly. Production scale could also be considered a barrier, as the industry can't yet make enough solar panels to satisfy demand. The [...]

What are the ways that Solar Energy is more environment-friendly and feasible than Nuclear Energy?

June 2nd, 2009

The more, the better. The arguments should be at least remotely feasible. I'm looking for ecological arguments why Solar Energy is a better alternative than Nuclear Reactors. Just list as many as you can come up with. Its all about the "after life" of the energy source. With solar panels there is some carbon and [...]

How do places with wind and solar energy sustain their power?

May 24th, 2009

Some places rely on solar and wind energy right? To power their homes and such. How do they use energy in the night or when there is no wind? Do they have something that stores the energy like a big battery or something? I have to “make” a green city and it will use renewable [...]

How much money would it cost if we used solar energy and kinetic energy to supply the united states?

May 15th, 2009

I need to know how much money it would cost to supply the entire united states with kinetic, wind, solar, and hydro-electric energy THANKS!!!! First we would have to spend some more money on research to improve our current technologies. powered by Yahoo Answers addthis_url = ‘http%3A%2F%2Fwww.renewable-energy-at-home.com%2Fsolar-energy%2Fhow-much-money-would-it-cost-if-we-used-solar-energy-and-kinetic-energy-to-supply-the-united-states’; addthis_title = ‘How+much+money+would+it+cost+if+we+used+solar+energy+and+kinetic+energy+to+supply+the+united+states%3F’; addthis_pub = ”;

How did the cycling of solar energy through the biosphere begin?

May 7th, 2009

Photosynthesis and cellular respiration are the same chemical reactions headed in opposite directions. Photosynthesis takes carbon dioxide and water and produces carbohydrates and oxygen. Cellular respiration takes carbohydrates and oxygen and produces carbon dioxide and water. Respiration is the exothermic reaction. Photosynthesis requires the input of energy from the sun in order to proceed. In [...]

What impact does solar energy have on the politics?

April 29th, 2009

I am writing a literature review essay..and i have to discuss about the political impact of solar energy..can anyone give me some advices or examples for what i can do about this topic. One of the issues the US presidential candidates are tackling is oil dependence, terrorist and concerns about global warming. Solar energy will [...]

I am considering a solar panels. How can I tell if my area gets enough solar energy a year to be worthwhile?

April 21st, 2009

I want to know how I can determine my area's (Rochester NY) yearly solar energy output to see if it would make economic sense to install solar panels. Any websites or resources where I can look? If you are looking for the cheapest electrical power available solar panels are not going to be what you [...]

How can I make a career in the solar heating / energy field?

April 13th, 2009

I'm working in IT Helpdesk field and no longer interested in this kind of work. I can't stand sitting at a desk in an office answering phones, e-mails and helping others with their technical problems. I am very good with technology/computers and want to start a career in the solar energy field, preferably as a [...]

What are the drawbacks from using solar energy?

April 6th, 2009

What are some drawbacks from using solar energy? I know that it is expensive, and it only works when the sun is out, what are 3 other drawbacks? Well for one, solar panels are not yet fully developed to the point where they're efficient enough for normal use for everyone and everywhere. Solar panels will [...]
