Question by somber_pieces: Which renewable energy form has the least amount of negative impact on the envioronment? Solar is nice, but how much energy & chemicals are used to make the solar panels. Geothermal is nice too, except along with the steam comes the other nasty byproducts that come up with the steam, depending upon

Question by bob d: questions about atomic energy? I’m wondering about multiple things. atomic questions———————————- 1.When it comes to atomic energy,it seams like the media demonizes atomic energy,is that true? 2.Did the Chernobyl incident “happen” due to the disabled safety features? 3.Did the power plant had a containment “dome”,like all power-plants today? 4.Why does the

Question by Ottawa Mike: Is the climate change issue really about a push for renewable energy? Here is the scenario as I see it: We are being told to reduce CO2 emissions because they will contribute to catastrophic anthropogenic global warming. To achieve that, we are basically being told (forced?) to reduce coal and oil

Image by NNECAPA Question by Dana1981: If global warming stopped, why is the Earth’s heat content and energy imbalance still increasing? Some people like to argue that global warming stopped in 1998 or 2001 or 2003 or 2005 because global surface air temperatures haven’t increased much over the past few years. But since only about

Yes it is.
But, just now, is too expensive, so the best contribution to save the planet is to save energy.

It’s still kinda expensive, but that should change soon with thin film technology. But in principle, it’s as good as it gets.

good is a value laden term.
Are PV cells a sustainable form of E ?
To determine this requires consideration of the amount of non renewable resources used (and associated CO2 released) during their construction. In addition PV cells do not last forever, they run at optimal efficiency for 10-20 years technology dependant.
You need to consider the whole life cycle of the product.
Trees are natural solar power collectors, and photosynthesis is much more sustainable than PV.

Photovoltaic panels pay back the energy and CO2 used in their manufacture in at most 4 years. Since the panels generally last 20-25 years, they are a net win for the environment.
Are they cost effective? Not yet in most locations without subsidies. If the panels are used only to offset an expensive tier of electricity, then they can be very cost-effective.

Solar Power is Eco clean and has been around for a long time but to expensive for the masses.
Homeowners now have the opportunity for a Solar Electric System without the up-front investment.
You pay only for the electricity that is generated. What’s more, it costs the same as your electricity service does today, but unlike your electric company, the price will stay the same for up to 25 years. Join the solution and reduce our dependence on foreign oil! Sign up for Solar Power today and take a step towards energy independence.
