[QUOTE=PowerBall v1;39978660]Yeah, absorbing sunlight and converting to electricity, thus preventing it from heating up the atmosphere, doesn't contribute to global warming. Maybe solar panels cooling off during the night could affect some ecosystem, but I find it hard to believe.[/QUOTE] Current panels only have an efficiency of around 17% - the other 83% of energy is wasted as radiated heat
[QUOTE=Maloof?;39978674]Current panels only have an efficiency of around 17% - the other 83% of energy is wasted as radiated heat[/QUOTE] Compare this to 100% radiated heat when it hits the ground.
[QUOTE=PowerBall v1;39978681]Compare this to 100% radiated heat when it hits the ground.[/QUOTE] Nope- lighter surfaces such as sand [B]reflect[/B] heat straight back out into space (not with 100% efficiency but near enough). Cloud cover may hinder this. The problem with dark surfaces is that they [B]hold onto [/B]this heat and [B]radiate[/B] it over a longer period of time, hence unnaturally occurring night-time warming
That lucky old sun. also its their money, let them spend it on what they want. I mean what the hell would you idiots buy, Huh?
[QUOTE=striker453;39972788]Cost wise fossil fuel is still immensely efficient to solar energy and clean coal technology exists[/QUOTE] Because short term solutions are so great.
[QUOTE=The golden;39972173]What a waste of money. Holy shit there are so many other things that money could have been spent on. 600mil for 20,000 homes? Who the hell thought that was a good cheque to sign[/QUOTE] Higher initial cost, lower long term cost, that's generally how it is with clean energy, be it electric car, or solar power
[QUOTE=EvacX;39972103]600,000,000$ to power 20,000 homes. That's 30,000$ per household. That is a lot.[/QUOTE] $30,000 to power a household [i]forever[/i] [editline]20th March 2013[/editline] [QUOTE=Maloof?;39978674]Current panels only have an efficiency of around 17% - the other 83% of energy is wasted as radiated heat[/QUOTE] This doesn't use solar panels, it reflects light using mirrors to heat up a central structure and the heat boils water to spin a turbine
