A Textbook Example: Why American Schools Must Go Green
 Schools are a black hole for energy consumption. The buildings, which often serve as the hub of communities, are open from early morning to late at night. With air conditioning or heating systems that run continually, it is not unusual for a single building to use hundreds of thousands of gallons of fossil fuel each year. While this energy consumption is a major concern to students, teachers, administrators and the community ? who all wish to lessen dependence on fossil fuels ? school systems are moving at a glacial pace when it comes to making environmentally conscious decision regarding what technologies should power their facilities. |
US-India Solar Business Council Formed
In an effort to promote trade and investment in the solar industry between the U.S. and India the U.S.-India Business Council (USIBC) was formed this week. The USIBC is comprised of private-sector companies and seeks to help the United States' export solar technologies while furthering India's goal of reducing its dependence on imported coal and fossil fuels through the use of solar energy. The USIBC Solar Task Force is a subcommittee of USIBC's Energy, Environment, Enterprise (EEE) Executive Committee, which is comprised of more than 100 members. |
RENEWABLE ENERGY BUSINESS SECTOR RESPONDS TO RICK SCOTT ATTACK
 A group of businessmen, farmers and renewable energy advocates who met today to support Alex Sink for Governor, were abruptly met with an attack from the Rick Scott campaign. |
Green Collars--Where are the Jobs?
 What about a recently laid-off woman who now pushes a reel mower yard to yard to make money? Would lawn lady's be a green job created, a general job lost, or would the two cancel one another for a net job gain of zero? |

What's a Watt?
The evolving discussion over renewable energy technologies has a tendency to get a bit technical. Most of us who work in the renewable energy space take for granted that many potential customers, investors and partners haven't spent any time in academia studying photovaltaics or wind turbines. In fact, they may not have a background in general energy metrics. Terms that once belonged to the realm of industry-insider jargon are quickly becoming standard. Thus, anyone who wants to follow the renewable versus traditional energy debate needs to know what we mean when we say "watt." Here, then, is a brief crash course in energy lingo. |
Desertec Solar Hopes Cloud over as Support Starts To Waver
 A significant piece of good news for the ambitious ?400 billion (Dh1.87 trillion, US $509 billion) scheme came in April, when one of its members, Germany's Solar Millennium, said its 150 MW Kuraymat project in Egypt was nearing completion and could serve as a template for other north African solar farms. |
Cheaper, Better Solar Cell Is Full of Holes
 A new low-cost etching technique developed at the U.S. Department of Energy's National Renewable Energy Laboratory can put a trillion holes in a silicon wafer the size of a compact disc. |

that's one powerful inverter! where did you get it and how much did it cost?

When doubling voltage, wire size may be halved Let us say Power in watts (Volts X Amps) 100V X1A = 100 watts 100W at 10 volts = 10 Amps Wire gauge is very important at low voltages, due to low "pressure" the current flow (in amps) must be unimpeded... so you need thick heavy wire. Look at it this way, 746 watts = 1 horse power, a car starter is usually 1 HP or more, that is roughly 62 Amps at 12 volts raise the voltage 10 times, the current falls to 6.2 Amps You need FAT cables at low voltages

hahaha it sucks

kjpaint8 i agree i need to tidy up lol but the wires going from battery to inverter are large enough the smaller wires in video are coming from the solar panel and they connected to a regulator that only let 14.3 volts at 7amps to travel from panels to battery . thanks for comment .

Your batery bank wire need to tidy up and the batery cable is wrong Type Safty is more Important Thank you International Scouting

slickjimmy76 i have battery cable leads made from the plug on back of a old cloths dryer not sure exactly whtat gauge it is but it use to handle 220 and i have 3 marine batterys in series and at 400 watts im drawing about 42 amps . thanks for the comment !

Battery wiring is much too small- you will see smoke at about 700 watts. My little 300 watt pure sign draws 25 amps (12 volt 880 amp hour bank) at full load. Get some 0/2 welding cable for the battery interconnects. Love the the solar panel set up you have!

I was wondering if you could give me some information. I purchased a 5000watt modified sine wave power inverter. I have three duralast new marine batteries and i want to use it in my 23ft boat. I would like to run a portable air conditioner a 19inch flatscreen tv and a dvd player at one time. Do you think this will power all three of these items. Also what do i need to purchase to have the same set up as you do. Thank you
