As i understand it, solar power generated electricity still are not competitive, and require subsidies to be competitive. How much is the cost difference nowadays? When will it be competitive w/o subsidies? What is the likelihood that this will ever… Continue Reading
Did you know they can obtain up to 20% of total energy from renewable sources? What the heck are we doing in America? Nothing??? Let’s be serious. What are we, lazy or idiots?
Apparently this is the latest going green solar technology that will power our cities, see description here http://www.squidoo.com/solarchimney. Is this actually going to work? They have a great computer graphics video here, but a tower 1 KM tall? can they… Continue Reading
I’m interested in heating our water with solar energy. We live in Virginia, and have direct sun on our ranch style roof. How much would it cost to purchase the technology and to maintain solar panels just to heat our… Continue Reading
is there really a technology more efficient and cheaper than solar cells? if yes, what is it? can you explain it? is there really a technology more efficient and cheaper in generating electricity or energy than solar cells? if yes,… Continue Reading
Right now, solar efficency is around 30-40%. So as technology increases, and this % increases to 90+%, could it be a reasonable source? I am not talking about having Boeing 747’s run off of them, just like small Cessna’s. Keep… Continue Reading
The Pacific island of Palau is being proposed as the site to have microwaves beamed down from an orbitting satelite. http://news.yahoo.com/s/ap/20071223/ap_on_sc/space_power;_ylt=AsXoXCpo8gq2JVCGTeDXtXAPLBIF
Some states like TX and NJ will subsidize solar energy 40% worth. But the technology to date has been quite costly in spite of these states’ subsidizing the cost. However, solar energy is starting to turn the corner cost-effectively in… Continue Reading
Would like to know how much $ is reserved/set aside by Fed Govt to use solar energy tech for some Federal buildings – also how much money is being spent by Fed Govt on using non-solar air conditioning technology (traditional… Continue Reading
